In addition, studies suggest that high levels of B6 and B12 in the blood are correlated with higher risk of certain cancers, such as prostate and lung cancer. In my opinion, having mild nutrient deficiency is not cause for alarm if you're a fully grown adult, and in fact, studies suggest that malnutrition might confer a longer lifespan.
- zuminator 6y agoAre those malnutrition studies about nutrient deficiency or caloric deficiency?
- LegitShady 6y agoI do not think those are good suggestions for the average person. I've read meta analyses about low caloric intake but not about malnutrition, which in general is a bad idea. That being said most people who aren't severely restricting the types of food they eat, and eating healthy food, are unlikely to have significant malnutrition. The lung cancer thing I remember was specifically smokers, so its not straightforward.
- scythe 6y ago>studies suggest that malnutrition might confer a longer lifespan. There are some data suggesting that inadequate supply of this or that nutrient reduces certain aging mechanisms and leads to longer lifespans in a laboratory setting. However, outside of a laboratory setting these nutrient deficiencies can affect the body's ability to fight infections and heal injuries, which on average cancels out any benefits. More generally, trying to increase lifespan by adjusting the diet seems to me like trying to fix a car by playing with the buttons and knobs on the dashboard. You might obtain a small improvement, but you're not really going to get anywhere unless you open the hood.
