If there is one certain truth in this planet, it is aging. Everyone ages as aging is one of life's processes which cannot be escaped by anyone. Though inevitable, signs of aging can be staved off.  Health experts gave countless advice to slow down aging, 

Healthwomen explained how a person's nourishment is linked to aging. "Your diet can affect the way you age. Oxidative stress is the cumulative, day-to-day assault our cells endure. The longer we live, the more oxidative stress our bodies experience.

Studies show that there are several foods that appear to repair the toll this stress takes and even protect against further damage. The foods studied also increase the number of brain cells we have and improve their functioning."  

Costa Rica, Sardinia and Okinawa are the three of the places in the world with the longest-time living people. The secrets of their lengthy lives are attributed to what they eat.

Seaweed- Some seaweed types are highly comprised of fucoidans, also known as alpha-L-fucan.  According to Memorial Sloan-Kettering Cancer Center, "Fucoidan is a type of sulfated polysaccharide found in several different species of brown seaweed, including bladderwrack and kelp. Fucoidan contains galactose, glucoronic acid, xylose and several other major constituents that give the substance its potential health benefits."

Some of the numerous health contributions they give include fighting against high blood pressure, infections or allergies. They also contain substances good to cure cancer and tumor. Seaweeds have detoxifying elements that strengthen the body and fortify its ability to fight against diseases that can end up life at an earlier stage. Japanese centenarians credited their lives to this food.

Mediterranean Diet- A study that was released in the BMJ showed the relation between longer life and Mediterranean diet.  Immaculata De Vivo, associate professor of medicine at Harvard Medical School and one of the research officiator stated, ""Our contribution is that we provide a link at the molecular level, at the DNA level, of the association between the Mediterranean diet and longevity and beneficial health effects. We didn't find that any single component was driving the association. It was the entire package, the pattern of eating itself."

Less Meat- People from Costa Rica consume meat sparingly but eat big amounts of beans and fruits and green vegetables. They eat for 4-5 times a day with little quantity of food.
