4 eating patterns linked to longevity
Jan. 23, 2023—Want to live a long, healthy life? Putting the right food on your plate might make a big difference.
In a large, long-term study published in JAMA Internal Medicine, researchers found that healthy eating may help you lead a longer and healthier life. Four dietary patterns were linked to a lower risk of death during the study period.
Researchers analyzed data from more than 100,000 participants over 36 years to see how eating habits affect the risk of death. They found that participants who reported following one of four healthy diets had a lower risk of death and a reduced risk of cancer, heart disease and respiratory diseases.
The study analyzed four patterns:
The Healthy U.S.-Style Eating Pattern. It involves vegetables, whole grains, low-fat and fat-free dairy, healthy fats, lean meats, and poultry. It discourages red and processed meat, calories from added sugars, unhealthy fats, refined starches, and alcohol.
The Alternate Mediterranean Eating Pattern. It emphasizes filling your plate with plant-based foods and healthy fats. The diet stresses healthy fats, which include olive oil and seafood.
The Healthful Plant-Based Eating Pattern. It focuses on eating plant-based products and discourages all animal products.
The Alternate Healthy Eating Pattern. It involves consuming fresh veggies, fruit, whole grains, nuts, legumes, plant-based protein, fish and healthy fats. It discourages the consumption of red and processed meats and sugar-sweetened beverages.
