5 Tips for Future Interns to Promote Success during the Internship

By Tori Wannemuehler

Last Sunday was match day for future dietetic internship students. I remember being in their shoes only last year, eager for the year to come and excited for all the new opportunities I was about to experience. I genuinely am shocked that a year has already passed, but the opportunity to write this blog post gave me the chance to reflect on what has occurred over the past year, as well as the numerous lessons I’ve learned along the way. Here is a list of advice for future interns as things I have experienced firsthand, although I believe they apply to more than just the internship:

1. Allow yourself a buffer of time

This applies to just about everything that can be completed in the internship- studying for exams, assignments, checklist items, and even scheduled events. As a natural procrastinator, I find myself waiting until the last minute to accomplish tasks. This allowed me to fall into some sticky situations over the past year. Overestimate how much time you need to work on an assignment or how much time you need to get to rotations in the morning (traffic can often be unpredictable). This way you will be pleasantly surprised when you finish ahead of schedule and should you need the extra time you will be prepared.

2. Plan your schedule wisely

One of the most difficult parts of the internship and graduate classes is balancing all of your responsibilities and assignments. There are many tasks that need to be accomplished from many different sources, as well as various meetings or scheduled events. I personally find the best method for keeping organized is using a planner and an online calendar. At the beginning of each semester, I lay out all my syllabi, copy all the due dates and important events into my planner, and use that to navigate assignments. When I have a new event or meeting, I make note of it in my iCalendar, so I can see it in my phone or on my computer. I love getting reminders that I have a meeting coming up or an assignment due so that I do not forget. This might not be the best choice for you but be sure to find a system that works for your tastes and allows you to keep track of everything. In addition to this, be strategic on planning your schedule. I can speak from personal experience that scheduling a cooking demo the same weekend as a health fair and the same day as an exam will not set you up for success. Some of this is inevitable, but do not overestimate your capabilities only to be disappointed. Try and plan your days as to not stress yourself out with too many responsibilities.

3. The best thing you can be is flexible and open minded

I intentionally put these two points back to back to present some healthy balance. Creating plans and a schedule is great in theory, until something unexpected comes along that changes said plans. This has been a large theme in the lives of interns over the past month. The effects of COVID-19 have significantly changed our methods of education, and no one planned to complete the semester remotely. Learning to be flexible and adapt to change can make you a better student and a better future RD. There are plenty of cool experiences you can have when you decide to say yes to something new. A prime example of this in an intern setting is during one of my rotations, my preceptor asked me if I would be interested in helping her with a cooking lesson after the time I was scheduled to leave. I was fortunate enough to be able to stay late and help her with this cooking lesson, and it was an amazing opportunity that I would not have experienced had I just stayed during my normal 8am-4pm workday. Being open minded to new opportunities and flexible will get you farther than you can imagine.

4. Have an outlet to give your mind a break, and incorporate it into your schedule

This lesson is a huge one that I feel like most people, interns or otherwise, could benefit from learning. The internship is difficult, there is no getting around that. You need to find ways that help you take a break and relieve some stress. Whether that be working out, hanging out with friends, getting outside, or anything else you can think of, find something you love to do and make a point to incorporate it into your daily or weekly schedule. Do not forget to prioritize your mental health, you deserve a break.

5. Do not overwork yourself; know when to move on

I had an eye-opening conversation early this year. I was talking with someone about having a routine and giving your all. I said that I struggled to give 100% to all the tasks I had on my schedule, as I did not feel I had enough hours in the day to accomplish everything on my plate to perfection. That person told me that I was looking at it from the wrong angle. They went on to say if you’re giving 100% all the time, you will burn out, as it is okay to not give your best effort each and every day. At times, you need to learn when enough is enough and realize that not everyone will be as critical of your own work as you are. You could work for 16 hours a day on everything you have and still feel like you have unfinished business. To that point, set limits for yourself. For me, this is giving myself an hour after rotations are done to relax, then working on whatever is on my plate for the day until 8pm, then taking the rest of the night off. This allows me to get work done daily, but not be overwhelmed and burnt out. Getting into a routine and setting boundaries for yourself will help you navigate the work-life balance associated with the internship and set you up for success.

I hope these tips are helpful for future interns as well as anyone else reading this. While the past year has been one of the most hectic years of my life, it has also been one of the most rewarding and I have experienced a tremendous amount of growth, both professionally and personally. I am excited on behalf of those starting internships and wish they can grow and take time to enjoy the internship over the next year.

The following images are photos I have taken throughout the year and a little background as to why it is relevant- feel free to include any of them!

The Truth about Soy!

By Haley Serra

Soy, or the soybean is a legume of the pea family, named because it grows in pods containing seeds or “beans” as they are commonly termed. There are various foods originating from this plant including edamame (immature, green soybeans), soymilk, tofu (soy curd pressed into block form), tempeh (fermented cooked soybeans), and miso (fermented soy paste), among many others.

Retrieved from https://www.healthline.com/nutrition/foods/soybeans#nutrition

Okay, so soy has gotten a bad rap in the past. I’m sure you’ve heard the accusations. The main claim is “soy causes breast/prostate cancer”. This is a major health claim. I too, would be concerned if I heard this with no other knowledge. So, where do this come from?

These claims about soy stem from their high concentration of compounds called isoflavones, which are a type of plant estrogen (phytoestrogen). These compounds function similarly to human estrogen but have much weaker effects. The idea is plant estrogen adds to human estrogen, and increased estrogen has been linked to certain types of cancer. In theory, this may seem like a logical connection, HOWEVER, we have to base our knowledge on evidence. After delving into the current research on soy, we can break down these misconceptions.

Retrieved From https://www.delishknowledge.com/how-to-make-crispy-baked-tofu/

First and foremost, many studies that saw this relationship were completed in rats. Rats process soy and its compounds differently than humans, and these effects have not been replicated in humans. Furthermore, these research claims often reference extremely high doses of phytoestrogens, way exceeding the amount you would be able to consume eating soy foods.

A meta-analysis completed in 2018 of 30 case control and cohort studies from the United States Europe, Japan, and China, intakes of soy food were significantly associated with a reduced risk of prostate cancer [1].

The Shanghai Women’s Health Study is one of the largest studies of soy and breast cancer risk. This study followed Chinese women for 7 years and the results of this study showed that women who consumed the most soy had a 59% lower risk of premenopausal breast cancer compared with those who consumed the lowest amount [2].

The American Cancer Society’s statement on soy is “so far, the evidence does not point to any dangers from eating soy in people, and the health benefits appear to outweigh any potential risk” [3].

Retrieved From https://www.culturesforhealth.com/learn/recipe/yogurt-recipes/homemade-soy-milk/

Based on this research, consuming soy foods may have a protective effect on hormone sensitive cancer. But that’s not the only benefit dietary soy has to offer!

Soy contains all of the essential amino acids, making it a high-quality, complete protein source. It is also rich in nutrients including fiber (both soluble and insoluble), B vitamins, calcium, magnesium, potassium, and omega-3 and omega-6 fatty acids. Furthermore, it is naturally free of cholesterol and low in saturated fat making it a heart-healthy meat alternative. These translate into decreased cholesterol, decreased blood pressure, and decreased risk of chronic disease.

Retrieved From https://frommybowl.com/easy-baked-tempeh/

If you were someone who was skeptical of soy, rest assured. The bottom line is soy provides many health benefits, can be part of a healthy diet, and is a super versatile food.

Retrieved From https://www.foodnetwork.com/content/food-com/en/healthyeats/2013/07/15-surprising-ways-to-enjoy-edamame.html

If you’re new to this food, here are some ways to incorporate soy products into a healthy diet.

Bake in the oven or pan sear tofu or tempeh to add to rice bowls, in stir fry’s, or on top of salads
Use soymilk in place of cow’s milk in oatmeal, cereal, and baking
Add soymilk or silken tofu to smoothies to give them a smooth, creamy texture
Toss edamame into salads, soups, or on their own as a protein rich snack!
Replace beef burgers with soy-protein based burgers once in a while.

Intermittent Fasting: What the Research Shows

By Sam Scardigli

Source: https://www.vectorstock.com/royalty-free-vector/logo-of-intermittent-fasting-clock-face-vector-23297574
Intermittent fasting has become an increasingly popular diet of choice for many Americans looking to improve their health, but is it effective?  Is it practical?  Let’s jump into some of the most recent research to find out how effective intermittent fasting is for weight loss and overall health, while also evaluating its practicality.  

What is an Intermittent-Fasting diet?
First, the numerous different ways to intermittently fast will be discussed.  Intermittent fasting can be defined as eating patterns where individuals go extended periods of time with little or no caloric intake, with intervening periods of normal food intake, on a recurring basis3.  The logic behind intermittent fasting is that current regular eating patterns of three meals per day plus snacks is likely to lead to overconsumption of food, ultimately leading to weight gain and/or chronic disease.  By shortening the time window in which people eat, it makes it more difficult to overeat.  As mentioned previously, there are multiple different ways to intermittently fast.  The three most common forms from recent research are alternate day fasting, 5:2 intermittent fasting, and daily time-restricted feeding.  Alternate day fasting involves alternating fasting days (no calories consumed) with eating days (food and beverage consumed as desired)4.  5:2 intermittent fasting allows individuals to eat what they desire for 5 days per week while severely restricting their intake on 2 nonconsecutive days during the week.  Lastly, daily time-restricted feeding allows individuals to consume food as desired during a set time window each day while fasting for the remainder of the day.  A typical daily time-restricted feeding regimen is consuming all calories between 10:00 am and 6:00 pm and fasting the other 16 hours of the day.  

Weight Loss


The driving force for many people wanting to start intermittent fasting is for weight loss.  Research has shown that humans tend to behaviorally reduce their food intake when performing daily

intermittent fasting (daily time-restricted feeding)1.  A small recent study that lasted 8 weeks resulted in an average of 9% weight loss in obese individuals 1.  It was noted that participants in the study tended to struggle to meet energy requirements when eating in a more restricted time window.  

Overall, studies on all three types of intermittent fasting have proved to be effective for weight loss in normal and overweight individuals.  However, lots of research is showing that alternate day fasting and 5:2 intermittent fasting are difficult to sustain long-term 4.  During fasting days, many participants reported extreme and persistent hunger, causing discomfort 1,4.  Individuals performing daily time-restricted feeding, however, seem to deal with fewer hunger issues 1.  



Effects on Chronic Disease
Intermittent fasting has not only shown promise for weight loss, but also in improving chronic disease measures.  Cardiovascular disease risk seems to improve during intermittent-fasting 2.  Intermittent fasting has shown to improve blood pressure, cholesterol, and blood glucose control, all of which contribute to a lower risk of developing cardiovascular disease 2.  Improved glycemic control in individuals with type 2 diabetes has been observed during intermittent fasting when compared to those who are on a regular diet as well 1.  Additionally, intermittent fasting has also shown reduced markers of inflammation in the body 2.  The evidence on improving chronic disease risk through intermittent fasting isn’t as strong as the evidence for weight loss.  However, recent research is promising that intermittent fasting can reduce risk of cardiovascular disease while also providing an anti-inflammatory effect on the body.  
Ramadan
Interestingly, many Muslims throughout the world practice a form of intermittent fasting each year during the month of Ramadan.  Muslims taking part in Ramadan typically do not eat or drink anything during daylight hours and will consume one meal just before dawn and another after sunset 5.  This would be considered daily time-restricted feeding.  Many researchers saw the unique eating habits during Ramadan as an opportunity to research this form of intermittent fasting.  A recent research article stated that 60% of studies on fasting during Ramadan indicated significant weight loss, averaging around 3 pounds 4.  Additionally, improvements in cholesterol, blood glucose, and inflammation were noted in numerous studies 4.  This research further strengthens evidence that intermittent fasting can help aid in weight loss and may provide other beneficial health outcomes.  
Summary
Intermittent fasting appears to be a good option for weight control for those who struggle with overconsumption of food.  In addition to weight loss, some research is showing other potential benefits such as reduced risk of cardiovascular disease and lower levels of inflammation.  Although, types of intermittent fasting such as alternate day fasting and 5:2 intermittent fasting require periods of 20-36 hours with either no food or very little food intake1.  The ability to sustain these types of intermittent fasting is reported to be very difficult1.  Time-restricted daily feeding, however, seems to cause less of a hunger burden and may be the more practical option.  Time-restricted daily feeding typically includes 8 hours of eating time and 16 hours of fasting time, but slight changes can still allow for better weight control.  For some people, a 12-hour fast and a 12-hour eating time will help reduce consumption.  Overall, nutrition and eating habits are very individualized and intermittent fasting isn’t for everyone, but research indicates that certain types of intermittent fasting are reasonable options.

Healthy Eating on a Budget


By Macia Noorman

As nutrition professionals, we are constantly spreading the message to eat healthy. Eat more fruit! Eat more vegetables! But we sometimes forget that, for many people, that just sounds like dollar signs. Many people want to eat healthy, but don’t know how to do that on a tight budget.

I’ve found myself on a tighter budget than usual this year, and I am here to tell you that you can still eat healthy on a tight budget! It takes a little extra work and time getting started, but once you’ve built some new habits, it will feel like second nature. Here are a few tips to get you started!

Plan Ahead

Have you ever gone to the grocery store and started putting stuff in your cart and get home to realize that you have lots of odds and ends and no clue how to put them together? Or maybe you grabbed a whole bunch of fruits and vegetables that were still sitting there a week later, attracting fruit flies? All that food equals money sitting in a cabinet or landing in the trash.

It’s a lot easier to stick to a budget if you know exactly what you are going to buy and how you are going to use it before you ever set foot in a store. Start by finding a time every week that you can spend some time planning your menu for the next week and building your grocery list. I usually do my menu planning on Thursday or Friday during lunch and in the evening (because I rarely have enough time to get it all done in one sitting).

Building a collection of your favorite recipes and food blogs can make the planning step easier because you won’t have to come up with everything on your own. My two favorite blogs for menu planning are Skinnytaste.com (which even has weekly menu plans if you want to simplify this step even more) and BudgetBytes.com (because budget is right in the name!). And don’t forget to check the ads for your grocery store while you’re planning! Steak may be too expensive to have every week, but it might fit your budget once in a while when it goes on sale!

Shop Smart

You’ve got your list, now stick to it. But how can you do that for the lowest price? You could go to every grocery store around and price compare, but that would take all day! Chances are, one of your area grocery stores promotes itself as a lower cost option. Mine is Ruler Foods (their slogan used to be “measure the savings”). It’s a rare week that I can get everything on my list there, but I can usually get most of my items there and pick up just a few items at the more expensive grocery chain down the street.

A typical Ruler Foods bill for me is between $25 and $45 for breakfast, lunch, and dinner for five days for two people. I pick up the handful of items I couldn’t get at Ruler Foods (usually some produce and the occasional international ingredient) at Schnucks for another $25 to $30. That means, my weekly grocery bill is usually about $50 to $75. For three meals a day. For five days. For two people. That comes out to $1.66 to $2.50 per meal. I’m paying McDonald’s prices for healthy, home cooked meals!

COOK

Here’s the kicker. To eat healthy on a budget you have to be willing to do some of your own cooking. I happen to take that to the extreme and even make my own breads and marinara sauce most of the time (I also have a food allergy that makes that a necessity, but that’s another blog post).

Cooking doesn’t have to be a huge chore that takes over your entire life. The two blogs I mentioned earlier (skinnytaste.com and budgetbytes.com in case you forgot) have tons of very easy recipes that anyone could make with some very basic skills and kitchen supplies. If you’re busy during the week and just don’t have the time to cook dinner every night, try to set aside some time on the weekend to prepare for the week ahead. And become a fan of leftovers! A lot of recipes are designed to make four servings. That means you can cook once and eat four meals!

You may be saying, “This is all well and good theoretically, but the proof is in the pudding.” So, here’s my proof!

Sample One-Week Menu

I only plan a menu for Monday through Friday. We eat whatever is leftover on the weekends and are more likely to go out with friends.

Day
Breakfast
Lunch
Dinner
Monday
6 oz Greek yogurt
½ cup blueberries
1 teaspoon honey
Schnucks bakery muffin
Skinnytaste Chickpea Tuna Salad
1 slice bread
BudgetBytes Chili Lime Shrimp Bowls
Tuesday
Skinnytaste Breakfast Pizza
1 banana
Leftover Chili Lime Shrimp Bowls
Skinnytaste Pressure Cooker Pozole
Wednesday
Leftover Breakfast Pizza
1 banana
Leftover Pressure Cooker Pozole
BudgetBytes Lemon Ricotta Pasta
Thursday
3 Skinnytaste Petite Quiches
1 cup cantaloupe
Leftover Lemon Ricotta Pasta
BudgetBytes Carnitas & Pickled Red Onions
3-4 tortillas (tacos!)
Friday
3 Leftover Petite Quiches
1 cup cantaloupe
Leftover Carnitas &Pickled Red Onions
3-4 tortillas
BudgetBytes Spring Rolls & Quick Peanut Sauce

And here are my receipts! My grocery total for the week was $63.62 for two people. That includes three meals a day for five days. Our per meal price for the week is $2.12.

 

It takes some dedication and time to eat healthy on a budget, but it can be done! Decide to make a plan and stick to it, and you and your bank account will start to feel healthier soon!

Plant Forward Diets and Why They Shouldn’t Be a Trend

By Madeline Nathe

            If you follow food trends you’ve probably heard of the phrase “plant based.” Even if you don’t follow food trends I’m guessing you’ve heard your doctor, dietitian, or mom tell you to eat more fruits and vegetables. But is that all that a plant based diet is? I want to dive headfirst into the idea of plant based diets and explore how you might be able to incorporate this into your lifestyle.

            First off is the “why.” Why would you as an individual and food consumer want to take up a plant based diet. As a dietitian whose SLU education taught her that evidence based practice is best, I found some research to support this. And as someone who knows that research articles aren’t the most exciting thing to read, I’ve boiled it down to the nitty gritty for you. Both the American Heart Association and the American Diabetes Association recommend following a diet with a variety of fruits and vegetables, whole grains, nuts, legumes, poultry, fish, and vegetable oils.1,2 All but 2 of the items on that list are plant based. Fruits and veggies also have high contents of phytochemicals, antioxidants, and phytoestrogens which can help reduce inflammation, inhibit oxidation of bad fatty acids, and lower blood pressure.3 Plant based foods are high in dietary fiber, a component of foods that is very important for our health in various ways. Fiber gets fermented in our gut and provides a healthy microbiome – this plays an important role in our immune system, our brain health, and perhaps even body weight.4,5 Some other reasons to go plant based include environmental and sustainability reasons, cost purposes, and a desire to eat less processed foods – each of these reasons could be a series of blog posts on their own, so we’ll just focus on the basics today.

Source: https://www.plantforwardkitchen.org/
            Now that we’ve got a good idea of why and how this can be a good practice for our health, I want to think of it in a slightly different light. The word “diet” often scares people and makes them thing of cutting out sweets, bread, or entire food groups (I’m looking at you, keto diet). In actuality, the word diet literally means “the kinds of food that a person, animal, or community habitually eats.”6  I’d also like to think of plant based diet as a plant “forward” diet. The word “forward” in general sounds more optimistic to me, which is something I like when thinking about food, but it is also makes me think of plants being at the forefront of my meal, plate, or menu.

As Americans and especially Midwesterners, we often think of dinner as what meat or protein we’re going to have and then what do we eat as sides, which is where we add in our veggies. If you are making a plant forward meal, you might be planning your meal around what fruits and vegetables are in season and what protein would complement it, versus the other way around. Thinking of meat as a supplement to your meal and not the main focus, is one way to practice a plant forward diet. Another option you can do in practicing plant based diet would be to swap meats for beans, tofu, or other plant proteins. You could also do half meat and half plant based. Something I saw during one of my food service rotations was using half ground beef and half mushrooms in tacos and meatloaf recipes. Mushrooms still provide a meaty flavor and texture but overall you are cutting back on the amount of meat you’re using. However, the best advice I can give when cooking vegetables and fruits is to properly season and highlight them. Use spices, acids, vinegars, seeds, herbs to complement the fruit or veggie so they shine and become truly delicious. I hosted a popup dinner last year for my capstone project and served a beet salad (see picture above). The salad was simple and had 6 ingredients: beets, oranges, cumin, sumac, chickpeas, cilantro, plus olive oil and salt (absolute staples you need in your kitchen). Many people at the dinner told me they never liked beets until they tried that – and I attribute it all to the power of using tangy acids, spices, and bright oils to elevate the beets.

But how else can we make this fit in our lifestyles successfully so that it’s not just a short term trial like so many other diets? In the US we’ve seen a decline in home cooking and a rise in eating out, buying convenience food items, and premade fast casual options. Perhaps plant forward for you means cooking at home because you won’t purchase and consume as much meat. Or maybe it means finding less processed, convenient snacks and swapping them with a homemade plant forward option. Challenging yourself to do meatless Mondays, or simply eating a smaller portion of meat is one way to ease into plant forward eating. Figure out what you could play with and know what you will not change in your diet. For me, its dairy. I know that dairy is a great source of protein and nutrients for me. I see this as a nutrient dense food in my plant forward diet. Because of that, I choose to go plant forward in other areas of my diet.

Stepping into a plant forward lifestyle and diet can be intimidating at first. Just simply walking around the farmers market always inspires me and gets the wheels turning about what plant forward meals I want to make. The produce is beautiful, it is always buzzing with people, and during peak summertime there’s usually too many delicious fruits and veggies to bring home at once. This is a trendy “diet” right now, so I’m seeing lots of food bloggers, magazines, and Instagram accounts developing plant forward recipes. Seeing a picture of a beautiful dish can usually get me in the kitchen to try it out for myself. Finding your own way to practice plant forward eating will lead to health benefits and a new found exploration for ingredients, meals, and menus. And as Michael Pollan says, “Eat food. Not too much. Mostly plants.”7 Happy eating!

Here are some Instagram accounts, blogs, and cookbooks that I gravitate to for plant forward eating:

All About Nixtamal

By Sarah Morrissey

While the flavor of sweet corn is delicious it is own right, there is a something different to the flavor and texture of corn-based foods like corn tortillas and grits. The commonality in flavor of these familiar foods can be credited to a process called nixtamalization.


What is Nixtamalization?

Nixtamalization is an ancient Mesoamerican technique where whole dry corn kernels are mixed with an alkaline solution, heated, and soaked overnight. Extensive soaking the dry corn in a basic solution, typically slacked lime (calcium hydroxide) or wood woodash (potassium hydroxide) softens the corn. Once washed it can be more readily consumed as hominy or ground into masa.

Historical Context

The earliest evidence of maize, or corn, processing in Latin America dates back to 1500 -1200 BC. The softness of the corn was likely the appealing attribute as it was practically easier to chew. Retrospectively, it is now understood that this process enhances the flavor and aroma, reduces the susceptibility to common molds and fungi,  and improves the overall nutritional quality of the corn.

Lasting Nutritional Relevance
Nutritional comparison of whole corn to nixtamalized whole corn. | GRAPHIC BY SARAH MORRISSEY

Without nixtamalization, niacin (vitamin B3) is bound in the corn so our body is unable to digest it. However, with nixtamalization, niacin is released, therefore, preventing pellagra. Not only does nixtamalization free bound niacin, it increases the overall protein content of whole corn and increases the bioavailability of calcium, iron, copper and zinc. In a culture where dietary intake of calcium is relatively limited, the integration of calcium hydroxide has historically filled the nutritional gap. Overall, the cumulative effect of this basic process allowed ancient civilizations to thrive.

Nixtamalization Seen Today

The most widespread culinary application of nixtamalization is masa, which is freshly ground hominy. Masa which can be made into corn tortillas, tostadas, tamales, among other dishes central to Mexican food and culture.

The Future of Nixtamalization

Since the beginning of time, evolution has predominantly been driven by food and technology available for preparation. As technology has allowed food production to be more time-efficient and motivated convenience, it is important to be cautious when accepting these practices as inherently better. While much can be learned from the globalization of food, it is imperative to slow down and consider ancient techniques like nixtamalization that have sustained past civilizations to understand how they can benefit all aspects of the modern food system.

Fueling the Athlete: How to Build a Performance Plate

By Cameron Mottet


What is a Performance Plate?

As a runner, I know how important it is to fuel my body for performance. One strategy I use is building myself a performance plate. A performance plate is a meal that consists of the correct combination of foods based on your training load and activity level. The foods we eat play a significant role in our energy, hydration, and recovery status.

Important Components of a Performance Plate

There are five main components of a performance plate including: whole grains, lean proteins, fruits and vegetables, healthy fats, and fluid/hydration. To build a nutritious energy dense meal we will need to include these five important components on our plate.

  • Whole grains & energy-enhancing foods: 100% whole wheat breads, whole-grain pasta, brown rice, beans, potatoes, oatmeal, whole-grain cereals
  • Lean proteins or recovery/muscle-building foods: chicken breast, fish, turkey, lean beef, eggs, low-fat cheese, tofu
  • Fruits and vegetables or antioxidant-rich foods: apples, bananas, oranges, blueberries, strawberries, broccoli, green beans, spinach, carrots, cauliflower, tomatoes
  • Healthy fat or immunity/flavor-enhancing foods: salmon, nuts, seeds, olive oil, avocado, nut butters, oil-based salad dressings
  •  Fluid or hydration-promoting beverages: water, low-fat milk, 100% fruit juice

Training Load and Macronutrient Intake

As I mentioned earlier, as a runner, it is important to take into consideration the duration and intensity of my workout throughout the week. My longer and harder runs will require more calories and carbohydrates than my shorter and easier runs.

Light training days where I perform at a low intensity it is recommended to consume 3-5 g/kg/d of body weight in carbohydrates. Moderate training days where the duration of exercise is about an hour it is recommended to consume 5-7 g/kg/d of body weight in carbohydrates. For high training days, or endurance activity lasting from 1-3 h/d it is recommended to consume 6-10 g/kg/d of body weight in carbohydrates. Lastly, for very high duration greater than 4 hours it is recommended to consume 8-12 g/kg/d of body weight in carbohydrates.

Now, I know this may seem very confusing and hard to use, but below I have an easy way to divide up your performance plate based on hard and easy training days.
Hard Training Days

For competition days or harder training days, it is recommended to fill your plate half full of whole grains or other energy-enhancing foods, a quarter of your plate with lean proteins or recovery/muscle-building foods, and a quarter of your plate with fruits and vegetables or antioxidant rich-foods. You will also want to include a larger amount of healthy fats and adequate fluid intake for hydration.

Moderate Training Days

For in-season or moderate training days, it is recommended to fill your plate one third full of whole grains or other energy-enhancing foods, one third full with lean proteins or recovery/muscle building foods, and one third full with fruits and vegetables or antioxidant rich-foods. You will also want to include moderate amounts of healthy fats and adequate fluid intake for hydration

Light Training Days

For offseason, or lighter training days it is recommended to fill your plate half full of fruits and vegetables or antioxidant-rich foods, a quarter of your plate with whole grains or energy enhancing foods, and a quarter of your plate with lean proteins or recovery/muscle-building foods. You will want to include limited amounts of healthy fats and adequate fluids for hydration.
