Mediterranean or vegan? Steak or turkey schnitzel? Fruit, but wich one? A recent study analyzed which eating habits may contribute to healthy aging, identifying foods that could⁣ be particularly beneficial. The⁤ findings suggest that there isn’t one single “right” way to eat for ‍optimal health.

The study, published in ⁤ Nature Medicine,⁤ analyzed data from two large American long-term studies, following over 100,000 people for 30 years, from 1986 to 2016. The participants were predominantly women (66%) with an average age of ⁢53 at the study’s start.

Researchers defined healthy aging as reaching 70 years of age⁣ without major chronic diseases such as cardiovascular disease, cancer, or type 2 diabetes, and without important mental or⁤ physical limitations.

Only a ⁢Fraction of Participants Aged Healthily

Only ⁣about 9.3% of the participants achieved healthy aging, according to⁤ the study’s definition. Their dietary patterns shared⁤ some common characteristics. Those who ‍aged well tended to ⁢consume⁤ fruits,⁢ vegetables, whole‍ grains, legumes, nuts,⁣ and low-fat dairy products regularly.

Conversely, a high consumption of trans ⁤fats (found in potato chips and fast food), excessive salt, sugary drinks, and processed meats like sausage was associated with poorer health in old age. Highly processed foods, such ‍as frozen pizza, chocolate, and⁤ toast bread, also reduced the likelihood of healthy aging.

Researchers categorized participants into various nutritional‍ styles and compared them. The Choice Healthy Eating Index, characterized by high consumption of fruits, vegetables, whole grains, nuts, fish, and unsaturated ⁣fatty acids,‍ was associated with the greatest chance of healthy aging.

A Mediterranean diet, rich in vegetables, fish, and healthy oils, was also found to be nearly as effective. However, the study’s definition of the Mediterranean ‍diet placed less emphasis on whole⁢ grain products compared to the Alternative Healthy Eating Index.

A sustainable diet, sometimes referred to as a planetary health diet index, which aims to promote both human and environmental health, was linked to notably strong cognitive skills in older age.

regardless of the specific dietary style,certain foods were commonly consumed by the healthy agers. Researchers identified the following as particularly beneficial: fruits (especially berries), unsaturated fatty acids (found in olive oil and nuts), whole grain products, nuts and legumes (especially beans), green leafy vegetables (such as spinach, salad, or kale), yogurt, and fish.

Foods to Limit?

The study indicated ‍that some foods were associated with less successful healthy aging outcomes, including ⁤eggs and potatoes.

Foods that showed particularly poor associations with healthy aging included trans fats, sausage, butter, margarine, red meat, fries, fruit juices, and ‍poultry.

while many of these findings⁣ may seem intuitive, the researchers caution that the list is somewhat arbitrary and dependent on⁤ the specific dietary habits of the study participants. The study focused on evaluating this specific group and should not be interpreted as general nutritional advice. the researchers noted that, based on the study’s findings, wine might appear more beneficial than fruit juice, a conclusion that warrants further scrutiny.
