What should be on your not-to-eat list? Stay away from foods that are less nutrient-filled, as they typically add more body fat rather than build muscle. Processed foods should be avoided, as they’ve gone through many changes from their natural state, which can include the addition of flavors, preservatives, food additives, nutrients, or substances that have been approved to use in food items like fats, sugars, and salts, according to the Department of Agriculture (via Mayo Clinic).

Some examples of processed foods include sweetened breakfast cereals, cookie and cake mixes, packaged instant soups, carbonated soft drinks, packaged breads, and reconstituted meat products. according to Mayo Clinic, some of the highest processed foods are deli meats, crackers, microwaveable dinners, and frozen pre-made meals. Additional processed foods are salad dressing and jarred pasta sauce.

Goodson stresses the importance of limiting the consumption of highly processed foods with saturated fats and added sugars. Instead, opt for nutrient-dense foods, such as veggies, fruits, dairy, whole grains, healthy fat, and lean protein. She advises, “Specifically look to consume high antioxidant foods (typically produce) and omega 3-fatty acids found in fatty fish like salmon, trout and tuna, walnuts and seeds.”

In the timeframe leading up to a race or run, it’s especially important for runners to limit high-fat meals and snacks, which are likely to sit heavily on their tummy and make them not feel so great. “Focusing on carbohydrates in your pre-run snack with a little protein is the best option for fueling. If you ate a meal within 2 hours, you might be able to just eat a carbohydrate snack to fuel the run, depending on how long and intense it is,” Goodson explains.

Typically, a diet high in complex carbohydrates, some healthy fat, and protein are quite beneficial for runners. “Carbohydrate needs are based on how much you run/train. The more you run, the more carbohydrates you need. The less you move, the less you need. Think of it like driving your car around; if you drive your car around a lot you have to put gas in it more frequently.

She adds, “Runners should be eating often throughout the day to keep their bodies well-fueled. Most runners can think of shaping their plate with 1/3 complex carbohydrates, 1/3 high-quality protein, 1/3 veggies, some fat , and a fruit at meals on normal training days. snacks should consist of a carbohydrate and protein like whole grain crackers and cheese, Greek yogurt with berries and granola, whole grain bread with peanut butter and a banana, hummus with pita chips and string cheese, etc.”
