It has been found that lesser calorie intake could improve the functioning of important defensive cells in the immune system and therefore augment the human immune mechanisms.
The defensive T-cells get affected by the aging process, so their function decreases in putting up the fight with illnesses.
Previous studies showed that reduced calorie input reduced aging in rats, worms, yeast, zebra fish, flies, and spiders.
A new study decided to perform the same experiment on 13 young adult Rhesus monkeys and see the long term effects. By restricting calories, T-cell production improved, which further reflected on the higher resistance to infectious diseases.
The better resistance to infectious diseases we have, the longer we’ll live, the scientists say. They were more than happy to show that extending longevity lies in imbibing strength and vitality to the immune system.
A recent experiment found that fasting and low cal diets bring about longevity. Insulin growth factor-1 (IGF-1) is involved with the aging process. When you have a lot of this protein around it activates programmed cell death by turning on the suicide genes inside of cells. With low-cal diets and fasting, levels of IGF-1 drop. This allows cells that are damaged to repair themselves and their DNA, allowing the body to regenerating providing for longevity.
