Olympic Nutrition: 5 Foods to Enhance Athletic Performance

image

During the bitter cold winter this year, there is at least one thing to look forward to – The Winter Olympics!  Watching the Olympians may just inspire you to get off the couch and hit the gym or, better yet, step off the treadmill and hit the slopes! If you consider yourself an athlete, here are a few natural tools that could take your performance to the next level. Keep in mind, the recommendations outlined below are for those who spend at least 1 hour or more per workout doing vigorous physical activity. The suggestions won’t do much good, and could even be counterproductive for gym goers looking to merely shed a few pounds or focus on wellness. After all, these are added calories!   

Five functional foods that can enhance your athletic performance.

Beet Juice

Beets, like all fruits and vegetables, have antioxidants, fiber, and are rich in vitamins and minerals.  Recent research suggests that beets may also help improve athletic performance.  How so?  Beets are an excellent source of nitrates, which stimulates the production of nitric oxide.  Nitric oxide, also known as nitrogen monoxide, is a gas that widens blood vessels, increasing blood flow and oxygen to the skeletal muscles.  This leads to increased endurance and heightened strength.  If you want to give beets a try, world renowned sports dietitian Nancy Clark recommends 200 to 500 mL (6 to 16 oz) of beet juice or 75 mL (2.5 oz) of concentrated beet juice approximately two to three hours before an event.  You can opt for a cup of baked beets or other nitrate-rich foods such as spinach, arugula, or rhubarb.

Watermelon Juice

As our Bushwick Nutrition explored back in July 2013, watermelon contains a compound, L-citrulline that is a critical component of our new friend nitric oxide.  Similar to beet juice, watermelon juice can boost performance and relieve post workout soreness.  Research suggests that athletes can benefit from half a liter of watermelon juice post event and event training.  Watermelon is also, as the name suggests, about 90% water and lower in sugar than most juices- so it’s great for rehydrating. You can also count on a healthy dose of Vitamin A and C and even some potassium in your serving of watermelon juice. 

Dried Fruit: Prunes, Figs, Plums, or Other

Dried fruit is an oldie but a goodie.  It has been known to be an athlete’s trusted key  to a quick energy boost. Did you know that early Olympic athletes were given figs as a training food? Dried fruit keeps fresh in basically any condition so you can take it with you on long runs or keep in your gym bag for a quick snack after a workout. It’s critical to provide the body with a serving of easily digestible carbs to replenish one’s energy stores. Dried fruit provides a burst of calories but unlike processed sugary sports gels, you benefit from fiber and naturally occurring antioxidants. If you like bars over bags of dried fruit, you can try the KIND fruit and nut bar. They have no artificial ingredients and the nuts provide protein  - it’s a win win. If fiber bothers you, make sure to eat prunes and dried fruit only after your workout, or try lower fiber alternatives such as dried mango, orange slices, or apples.  

Sodium Bicarbonate

Does anyone remember this from their high school chemistry class?  Sodium bicarbonate acts as a buffer of lactic acid, the compound that makes your muscles burn while exercising.  Sodium bicarbonate can slow down the build up of lactic acid in the blood leading to improved performance in high intensity interval training (HITT) lasting about one to three minutes. You can find sodium bicarbonate in a capsule form just read the ingredient list to make sure there are few ingredients and none that you cannot pronounce.  

Chia Seeds

Touted as one of the “it” foods of 2013, chia seeds are a super natural food. The seeds contain nutrients like omega-3 fatty acids (healthy fats), antioxidants, protein, iron, and can absorb up to 10 times their weight in water, which make them great for hydration! In Mexico, both the Aztecs (fiercest warriors) and the Tarahumara Indians (barefoot marathoners of their time), used chia seeds as a staple in their diet. NFL players have also been known to use them for their intense training! Chia seeds are great for energy and a healthy digestion. Just be forewarned that when combined in water, as the recipe below entails, they get a little gelatinous, not necessarily a bad thing but be ready for some texture.

Chia Lemonade

  • ¼ cup of freshly squeezed lemon or lime juice (~ 2)
  • ¼ cup maple syrup grade B or Agave nectar
  • 4 cups water
  • 2 tablespoons chia seeds

Directions: Combine lemon juice, sweetener, and water in a large pitcher. Once well combined, add chia seeds and let mixture sit for at least 30 minutes, so the chia seeds plump up. Serve and enjoy!

Serves 5 cups. Per cup: 80 calories, 3 grams of protein.

Watermelon: Nature's Canteen

image

When the weather outside rises upwards of 90°F and humidity levels soar above 70%, it becomes crucial to remain hydrated. According to general guidelines, men and women should drink ~13 cups and ~9 cups, respectively, of water a day. This number should increase when you exercise, sweat a lot, or if you are overweight/obese. So make sure to always have water handy or…

Take advantage of seasonal foods that have high water content, such as watermelon. As the name implies, watermelon is almost entirely water – 92% (or higher) with 6% sugar and traces of protein. In season from July to September, watermelon is part of the Cucurbitaceae family, and is related to the cantaloupe, squash, pumpkin, cucumber, and gourd. Despite there being 1,200 known varieties, only about 50 are grown in the US. To find out more about your locally grown varieties, which are naturally low in pesticides and more wallet-friendly, check out What is Fresh.  

Delicious and Nutritious!
One cup of cubed red watermelon contains 25% of your Daily Value (DV) of vitamin C, 10% vitamin A (from carotenoids), 175 mg of potassium and one gram of fiber – all for only about 45 calories! Watermelon also contains magnesium, vitamin Bs (B1-thiamine and B6-pyridoxine) and has high content of lycopene, a powerful antioxidant found in the reddish pigment.

The Benefits of Watermelon

  • It’s a great low-calorie snack.
  • It’s a heart-healthy food according to the American Heart Association because of high potassium, magnesium and vitamin C content.
  • It decreases cancer risk due to lycopene content – specifically prostate, breast, endometrial, lung and colorectal cancers.
  • It supports healthy eyesight and prevents glaucoma.
  • It aids in the maintenance of electrolyte and cellular function.
  • It increases levels of arginine, an amino acid researchers believe improves blood flow and consequently high blood pressure. Preliminary evidence also shows that it may aid in preventing excess accumulation of fat in fat cells.

Selecting a Watermelon

  • Color: Deep red/pink is better. Recent studies confirmed that fully ripe watermelon has a much higher nutritional content, and is flush with lycopene, beta-carotene and phenolic compounds. If purchasing pre-cut watermelon, look for flesh that is a deep color with as few white streaks as possible. Today, 85% of all watermelons grown in the US are seedless. However, if you select a watermelon with seeds make sure it is deep in color or white. The underside should be creamy yellow, indicating ripeness. Note: seedless watermelons are not the result of genetic engineering but of hybridization.
  • Weight in Water: A fully ripe watermelon will feel heavy for its size because water content increases as it ripens. Heavier is better!

How to Store and Prepare
Whole watermelon is best stored below 70°F as room temperature has been shown to increase levels of lycopene and beta-carotene. Once cut, cover and refrigerate. Eat within a few days up to a week. Note: always wash the watermelon before cutting to eliminate any bacteria that may be on the surface, that way the knife won’t contaminate the inner flesh.

Ideas on How to Cook and Serve

Watermelon has a thirst quenching texture but is also delicately crunchy, which makes it unique.

  • Cut up into triangles or “melon balls” for an easy snack.
  • Make a fruit salad and add yogurt and/or granola.
  • Grill watermelon as a side dish or dessert.
  • Make ice pops or ice-cubes. Blend watermelon (no added water necessary) with fresh mint, crushed ginger, and black pepper. Freeze and enjoy!
  • Try one of many fresh summer salads including a watermelon and jicama salad or a watermelon and tomato salad (pictured above). Recipe: Mix 2 cups of watermelon (cubed) with 1 red tomato (½ inch pieces) and chopped fresh basil. Drizzle balsamic vinegar and sprinkle crumbled feta or queso fresco. So easy, and so tasty!
