Chilis are indeed full of nutrients and antioxidants. And researchers saw its benefits of lengthening a lifespan. But researchers could not explain completely how red chili pepper makes life longer to chili-lovers. However, they have a theory that may be a possible reason behind longevity. The main component of red chili, protects the body against obesity and lowers the risk of cardiovascular diseases. It has anti-microbial properties that could alter the gut's bacteria, shielding it from obesity and cardiovascular diseases. Also, it contains a lot of other nutrients like vitamin B and C and a compound that turns into Vitamin A, which all contribute to the beneficial effects.

But, researchers do not yet prove that red chili peppers truly cause longevity. They need more researches and experiments to make this theory scientifically factual.

But whatever. I do not care. Red chili peppers are part of healthy foods, and healthy foods do really make life longer. So, if you want your dog to live longer, feet it with a red chili.
