Superfoods and risks

Some super foods like broccoli, lentils and blueberries can be harmful if consumed in large quantities. That's the result of a recent study of the effects of antioxidants in these foods.

Blueberry.

Scientists have found that consuming too much superfoods also means losing the balance between the amount of antioxidants (which slows down the aging of muscles, reducing the risk of disease. heart and cancer) and oxidizing agents.

Researchers at the University of Kansas Pulmonary Experimental Laboratory have studied ways to improve oxygen supply to skeletal muscles during physical activity using antioxidants.

Their findings suggest that sometimes antioxidants may reduce muscle function and increase fatigue during exercise, which really reflects the effect of oxidants.

Studies on animals with different doses of antioxidants give results: samples taken with too many antioxidants exhibit muscular dysfunction.

Professor David C. Poole, from the lab, said: "A person who is treated after a heart attack will feel that walking on a treadmill is very difficult. Their muscles are painful and stiff. We tried to understand why blood cells do not circulate properly and why they cannot carry oxygen to the muscles, as always happens in healthy people. '

A lab researcher, Steven Copp, added: "Antioxidants are one of the words we are familiar with right now. But what many people don't think about is the balance between anti-substances. Oxidation and oxidants are really necessary.

One of the findings in the study is that you can't just give your body a large amount of antioxidants and expect some health benefits. In fact, you can really make health worse '.

Professor Poole said that in the past, most antioxidants are thought to help the body get better, but their studies have shown that antioxidants can actually hinder signaling mechanisms. Important for muscles to function effectively.

Therefore, before giving advice to consume a lot of antioxidants, we need to understand more about their function in physiological systems and in different circumstances such as exercise.
