| Abstract: |
| Objective The relationship between aging and diseases and the research progress on the anti-aging effects of
major nutrients in diet were reviewed. Methods Based on extensive literature this study explored the essence of aging
investigated the causes of diseases and elucidated the mechanisms of anti-aging effects of major nutrients in diet. Results
Aging is essentially the accumulation of microscopic cell damage over time resulting in the formation of senescent cells
SC . This process is accompanied by an increase in the expression of senescence-associated secretory phenotype SASP
in cells leading to systemic chronic inflammation and a decline in immune system function. Aging is a common
underlying factor for various age-related human diseases and it also increases the frequency and susceptibility of serious
diseases such as cancer diabetes and the COVID-19 pandemic in the elderly. Aging is not positively correlated with
age and scientific dietary nutrition can delay aging. Conclusion Under the premise of controlling carbohydrate intake
complex carbohydrates and their metabolic intermediates can act as anti-aging agents by regulating cell aging protein
balance and inflammation. A diet with a ratio of plant proteins and proteins to high carbohydrates of less than 1 ∶ 10 is
beneficial to health and longevity during the aging process. Fatty acids especially those rich in ω-3 polyunsaturated fatty
acids PUFAs have been shown to be beneficial in ameliorating age-related diseases. Vitamins such as D E and B2
appropriate minerals such as Mg Zn and Fe plant polyphenolic compounds and probiotics in the diet all have antiaging effects and promote health and longevity. |
