Six Healthy Diets That Promote Longevity
In various diets, staples, fruits, vegetables, aquatic products, soy products, and tea are the six categories associated with healthy longevity in the elderly.
Recently, Peking University and the China Aging Research Center found in a study on factors affecting healthy aging in China that high-age elders who eat mixed grains as their staple food have better health outcomes than those who eat rice, while those who eat wheat-based foods have better health than those who eat mixed grains.
The study found that high-age elders who regularly consume fresh fruits have better health than those who don’t—due to the high levels of vitamins and dietary fiber in fresh fruits. Similarly, elders who frequently eat fresh vegetables have better health, thanks to their rich chlorophyll and vitamins.
Research indicates that regular consumption of fish and seafood significantly correlates with better health in the elderly. Fish and seafood proteins contain all nine essential amino acids required by humans and are easily digestible, with 87% to 98% being absorbed by the body.
Soy products are another significant dietary factor related to elderly health. They are rich in plant protein, contain a high proportion of linoleic acid, and are cholesterol-free—all beneficial for the health of older adults.
Tea is also significantly linked to elderly health. Tea contains over 500 chemical components, including proteins, amino acids, polysaccharides, vitamins, and inorganic salts with nutritional value. It also contains abundant bioactive substances—tea polyphenols—which help prevent various diseases and thus contribute to healthy aging.
