Chlorella, the green life extender
Rats that are fed with chow that is mixed with Chlorella live longer than rats that are given standard feed. Japanese scientists from the Yakult Central Institute for Microbiological Research discovered the life-prolonging effect of Chlorella some fifteen years ago.
The researchers experimented with a type of lab rat with a genetic predisposition to cardiovascular disease. They divided their animals into 4 groups, and gave one group standard chow. The other three groups received feed that had been enriched with 5, 10 of 20 percent Chlorella.
If the rats had been human adults, they had been given about 25, 50 and 100 grams of Chlorella/day.
Yup, that's a lot.
The rats given Chlorella by their feed lived longer than the rats in the control group. The larger the dose, the more prominent the life-prolonging effect.
The blood pressure of the rats increased as they got older, but supplementation with Chlorella inhibited that process. [Figure] At the same time, Chlorella improved the cholesterol balance and reduced the risk of brain haemorrhages. In the type of lab rat that the Japanese used, brain haemorrhage is a prominent cause of death.
The researchers suspect that Chlorella's life-prolonging effect in this animal study is caused by three types of ingredients: arginine, an amino acid that helps blood vessels to remain supple, carotenoids like lutein that protect enothelial tissues against aggressive molecules, and phospholipids, which plays a role in collagen metabolism.

Delay aging without strict diet: supplement with ketones
When you fast, and also if you follow a strict low-carb slimming diet, and the body goes over to using fat as its main fuel, the concentration of ketones in the blood rises.
Animal study: half cup of green tea daily is life extending
If you react in the same way to EGCG, the most important bioactive substance in green tea, as the mice that American sports scientist Brandt Pence used in his experiments, then you'll live longer if you drink half a cup of green tea every day.
The anti-AGE-ing effect of olive oil
If olive oil is your main source of fatty acids, then you probably live longer than if the bulk of your fats come from butter. Spanish researchers at the University of Cordoba discovered this in an experiment in which twenty healthy over-65s participated as test subjects.
