Statins were more effective at lowering cholesterol levels compared with six dietary supplements touted for heart health benefits, including managing cholesterol.

A 2022 study found that women ages 35 to 69 who ate vegetarian diets were significantly more likely to break a hip than peers who ate fish or meat. Vegetarians need to be sure they get adequate amounts of dietary protein, calcium, vitamin D, and other micronutrients to maintain bone health.

Over-the-counter supplements touted to support prostate health are popular, and supposedly help prevent and manage symptoms of an enlarged prostate (benign prostate hyperplasia). Some of the ingredients are said to protect against prostate cancer or slow its growth. While research has explored supplements’ role in prostate health and some had positive results, the findings are far from conclusive. A better dietary option for prostate health is to follow a plant-based diet like the Mediterranean or DASH diet.

Many people have misconceptions about avoiding heart disease. One involves the use of over-the-counter fish oil capsules, which do not prevent heart disease in healthy people.
