Choosing the right energy foods doesn’t have to be complicated. It just takes knowing a few key things about how nutrients work in the body and which foods are good sources of those nutrients.
Carbohydrates are known to be an energy storehouse for athletes, but certain vitamins and minerals play an equally important role in helping us feel energetic. The important thing to remember is that real energy comes from food. “Energy” pills or supplements claims haven’t stood up to scientific study when compared to actual food. “Energy” drinks rely on extreme amounts of caffeine which does increase alertness but isn’t a substitute for real food. Lastly the body prefers to use protein for important biological functions instead of burning it for energy. A protein shake before exercise won’t give you the same energetic feeling that carbohydrates will.
Repeat after me, carbohydrates are good….
Ignore the latest anti-grain food fad and choose diverse sources of whole grains for maximum energy. Whole grains differ from refined grains because they haven’t been stripped of the nutrient rich outer bran and germ. These contain fibre, minerals, vitamin E and B-vitamins. B-vitamins help the body convert calories into useable energy. Again and again whole grains are shown to increase athletic performance and contribute to lowered risk for heart disease and type 2 diabetes1,2. Whole wheat, brown rice and oats are classics. However, think outside the box with these ancient grains:
- Barley was once the food of the Roman gladiators1. A good source of fibre, selenium and B-vitamins, it works well in soups and pilafs.
- Millet has been cultivated for 8,000 years and is a staple food in many countries1. Not only a good source of carbs and fibre, it contains the minerals manganese and phosphorus, which are important in bone health.
- Buckwheat makes for delicious noodles and is gluten free.
- Spelt is another ancient grain that has higher protein content than wheat. It does contain gluten but might be less reactive in those with mild wheat sensitivities. It can be used in breads, pancakes and baked goods and has fibre, iron, zinc, magnesium and phosphorus2.
- Quinoa cooks faster than rice, is a good source of protein, and is gluten free.
- Couscous will cook in only five minutes and is perfect when you are short on time.
Quick Burst Energy vs. Long Sustained Energy
The Glycaemic Index is a tool that gives a numerical value to a specific amount of food based on how it affects your body’s blood sugar and insulin over a specific time period. Foods with lower numbers provide energy over a longer time. Whole grains, vegetables and other low glycaemic index foods will help give you sustained energy, but sometimes you want to grab something for quick, immediate energy during an intermission or a short break. In this case, protein or dairy isn’t what you want. Choose simple carbs from fresh grapes, strawberries, dried fruit, pretzels, oatbars, bread and preserves, or crackers. These get absorbed and used-up fast without leaving you feeling sluggish.
Non-grain food superstars for energy and wellness
- Mushrooms: Find ones treated with UV light in the produce refrigerated section of your grocery. The UV light increases the amount of vitamin D with one serving containing more than half your recommended vitamin D for the whole day. Vitamin D isn’t just important for bone heath, it is critical in immune function and disease prevention. You can’t feel energetic if you are sick. People with normal Vitamin D status in their body can fight infections better than those who are deficient.
- Sweet potatoes: Contain Vitamin C and the antioxidants beta-carotene and Lutein. Lutein is an antioxidant whose protective effect may increase when heated2. Sweet potatoes’ glycaemic index score is 41 points better than a standard white russet potato3.
- Beans, lentils, and peas: Only one half cup of these nutrient powerhouses have 23 grams of carbohydrate but they also have a full serving of protein too4. Plus they have iron and zinc, which are important in fighting illness. And, you can’t beat the price at $0.25/ serving.
