Eat Alpha Lipoic Acid-Rich Foods to Live Longer
A high dietary intake of foods containing alpha lipoic acid (ALA), a plant-based amino acid essential to the body’s metabolism, is associated with a 10 percent lower risk of death from all causes, an 8 percent lower risk of cardiovascular disease death and an 11 percent lower risk of coronary heart disease, reports a new study in The BMJ, a peer-reviewed medical trade journal published by the British Medical Association. An international team of researchers conducted a meta-analysis of 41 studies involving 1,197,564 participants that were followed for up to 32 years. They found that each additional gram per day of ALA (equivalent to one tablespoon of canola oil or a half-ounce of walnuts) was linked to a 5 percent lower risk of cardiovascular disease death. “A higher intake of ALA, however, was associated with a slightly higher risk of cancer mortality,” the researchers wrote. ALA is found in nuts, soybeans, canola oil, flaxseed, chia seeds and other food sources such as avocados, dairy products, navy beans and oatmeal.
