Decrease in polyamines with aging and their ingestion from food and drink

Home of Kyle J. Norton for The Better of Living & Living Health Human aging is a biological process, no one can stop, but delay it. It is possible that one person looks younger than his or her biological if one engages in healthy living life style and eating healthily by increasing the intake of good healthy food such as whole grain, fruits, vegetables, beans and legumes, etc. and reducing the consumption of harmful foods, such as saturated fat, trans fat, artificial ingredients, etc.
Spermidine is a naturally occurring polyamine involved in multiple biological processes, including DNA metabolism, autophagy and aging.
Decrease in polyamines with aging and their ingestion from food and drink
In the study to were measure the changes in polyamine levels during aging  in 3-, 10- and 26-week-old female mice, indicated that the level of polyamines in pancreas, brain, and uterus was maintained during these periods. The level of spermidine slightly decreased in intestine, and decreased significantly in thymus, spleen, ovary, liver, stomach, lung, kidney, heart and muscle during these periods. In skin, the level of spermidine was maximal in 10-week-old mice and markedly reduced in 26-week-old mice. The results suggest that maintenance of polyamine levels may play important roles in the function of the pancreas, brain and uterus in 3- to 26-week-old mice. We next looked for polyamine-rich food materials as a dietary source of polyamines. Foods found to be rich in polyamines included wheat germ, rice bran, black rice, Philippine mango, green pepper, Japanese pumpkin, nuts, fermented pickles, pond smelt, turban shell viscera, whelk viscera, salted salmon roe, salted cod roe, beef intestine (boiled) and liver of eel, beef, pork and chicken; and, as previously reported, soybean, fermented soybean (natto), mushrooms, orange and green tea leaf. These results offer useful information when it becomes necessary to ingest polyamines from food(18).
