We often write in these pages that the Mediterranean diet is good for your heart and brain. Now it appears that the Mediterranean diet may also help protect your telomeres, according to a Harvard study published in the Dec. 2, 2014, BMJ. Telomeres sit at the ends of your chromosomes and help protect the ends from fraying. Telomere length is considered to be a biomarker of aging: shorter telomeres are associated with a lower life expectancy and higher rates of developing chronic diseases. After analyzing the detailed food questionnaires and telomere measurements of more than 4,600 women, Harvard researchers concluded that a greater adherence to the Mediterranean diet was associated with longer telomeres, and that even small changes in diet made a difference. The Mediterranean diet is rich in olive oil, fruits, vegetables, nuts, and fish; minimizes red meats and processed meats; and includes a moderate amount of cheese and wine.

Confused about fats? Learn the latest on which fats offer the best health benefits.

If you have high blood pressure, scaling back the sodium in your diet is a smart move. Excess sodium (a main component of salt) makes the body hold on to extra water, which can elevate blood pressure. And most of us consume more than double the limit of 1,500 milligrams per day of sodium recommended by the American Heart Association.

Whole grains, including brown rice, are part of a healthy diet. However, health advocates have raised concerns about the tiny amount of arsenic that rice plants absorb from the soil. Also, a handful of studies have linked rice consumption to cardiovascular disease, although the evidence is preliminary and inconsistent. But now rice eaters can rest a little easier, thanks to a study in The American Journal of Clinical Nutrition.
