Nutritional supplements may not always be that good for us

 

New research suggests that nutritional supplements may, in some cases, lead to increased mortality rates.

I am sure that these supplements are very helpful in some situations, but it also is a reminder that there is no substitute for eating healthy, and that eating healthy in most cases is sufficient.

After all, we evolved for billions of years – counting our pre-human ancestors – eating whole organisms, and we have only had nutritional supplements for a few decades. Food contains nutrients in a form and combination that our bodies have evolved to make use of.  So when it is available to us, it makes more sense to rely on varied, fresh, mostly whole, and less processed foods.

And if it is local (family farms, CSAs), and grown in healthy soil (organic, biodynamic), it has additional benefits. It tastes great, supports the local economy and ecosystems, and supports a healthy form of food production. And if we need an extra boost, teas and infusions are a good first choice before supplements.

Research has suggested certain vitamin supplements do not extend life and could even lead to a premature death. A review of 67 studies found “no convincing evidence” that antioxidant supplements cut the risk of dying.

Scientists at Copenhagen University said vitamins A and E could interfere with the body’s natural defences.

“Even more, beta-carotene, vitamin A, and vitamin E seem to increase mortality,” according to the review by the respected Cochrane Collaboration.
