10 Scientifically Proven Foods to Eat for HUGE Endurance

It’s hard enough to pick out a work out, let alone match it with the perfect diet. There are lots of ways to exercise, and there are lots of foods to eat, and even more combinations of the two to try. Although nutrition is a big part of performance not a lot of coaches and athletes do a lot of research on what the best diet is for their specific workout needs.

Unlike strength training athletes which need lots of quick-release energy, endurance athletes need more access to long term energy. The best foods to eat for endurance athletes contain plenty of carbohydrates and protein, provide lots of vitamins and minerals, have a minimal amount of fat, and keep you hydrated.

Endurance training is a great way to exercise, although results in a study using rats it was found that endurance-type exercise may make the heart more susceptible to oxidative stress. Eating lots of foods with antioxidants you can prevent this oxidative stress. It is better to get antioxidants from your food rather than taking antioxidant supplements.

Not sure if you’re eating the right kinds of foods for your endurance routine? Look at the following delicious and nutritious foods:



Start your day off right with a bowl of oatmeal or add it to a protein shake for a healthy boost.  In a recent study, the beta-glucan found in oats has been proven to improve endurance in rats. Oatmeal is a whole grain which means it’s made out of carbohydrates also known as complex sugars. Unlike simple sugars, complex sugars aren’t very sweet but they are a better source of longer-lasting energy, just the kind of thing your body needs before and after exercising.  But that’s not all — oatmeal still has a few tricks up its sleeve. Oatmeal is also an excellent source of fiber and antioxidants.


Cherries like all fruits contain fructose, a perfect all-natural carbohydrate that makes cherries taste sweet and gives us the energy boost we need when exercising. Their tart yet delicious juice has been proven to decrease oxidative stress. Some cherries even contain high levels of polyphenolic compounds including flavonoids and anthocyanins which not only have antioxidant and anti-inflammatory effects but also reduce muscle damage. Cherries are a great treat to have after a long workout.



It’s true what they say about eating your greens: greens really do make you big and strong!  Kale is especially great at making your bones big and strong since it is such a good source of calcium. Kale also provides your body with all the fiber and minerals it needs without adding extra oxidants that could cause oxidative stress. Plus, kale contains plenty of vitamin C; vitamin C has been shown to help lower cholesterol levels. Kale keeps your heart happy, you’re oxidative stress low and your bones strong.


Milk is delicious and nutritious. It is a staple of the American diet, an important part of a healthy breakfast.
