Nutrition

How nutrients help

Nutrients, essential substances that help us grow properly and remain healthy, help maintain the immune system. In contrast to the delayed responses associated with malnutrition, vitamin A fights against multiple infectious diseases, including measles. Along with vitamin D, it regulates the immune system and helps to prevent its overactivation. Vitamin C, an antioxidant, protects us from the injury caused by free radicals.

Poly phenols, a wideranging group of molecules found in all plants, also have anti-inflammatory properties. There’s plenty of evidence to show a diet rich in plant polyphenols can lower the risk of chronic conditions, like hypertension, insulin insensitivity and cardiovascular disease.

Why don’t we Americans eat more of these plantbased foods and fewer of the bliss-based foods? It’s complicated. People are swayed by advertising and influenced by hectic schedules. One starting place would be to teach people how to eat better from an early age. Nutrition education should be emphasized, from kindergarten through high school to medical schools.

Millions of Americans live in food deserts, having limited access to healthy foods. In these circumstances, education must be paired with increased access. These long- term goals could bring profound returns with a relatively small investment.

Meantime, all of us can take small steps to incrementally improve our own dietar y habits. I’m not suggesting we stop eating cake, french fries and soda completely. But we as a society have yet to realize the food that actually makes us feel good and healthy is not comfort food.

The COVID-19 pandemic won’t be the last we face, so it’s vital that we use every preventive tool we as a society have. Think of good nutrition as a seat belt for your health; it doesn’t guarantee you won’t get sick, but it helps to ensure the best outcomes.
