 Certainly, the aging signs include not only grey hair, wrinkles but also decreased brain function, memory loss, and an increasing risk for chronic diseases like heart disease, cancer and osteoporosis. Healthy aging is also determined as living a longer, healthier life. Many studies have substantiated the connection between a healthy diet and prevention of chronic or age-related illnesses.
The best way to get a defense against aging is to adopt a healthy lifestyle that include regular mild physical activity, corresponding rest, giving smoking up, and a diet full of healthy foods and drinks. Dietary choice is good to detain the beginning of aging and age-related diseases. Besides the sooner you start, the greater the advantage.
Some foods and drinks include powerful substances called phytonutrients. Some researchers believe that they are able to unlock the key of longevity. Phytonutrients belong to the antioxidant family; they raven free radicals - molecules of oxygen that play a role in the onset of disease such as heart disorders, osteoporosis, cancer and Alzheimer's disease.
As we getting older, we become more sensitive to the long-term effects of oxidative stress and inflammation on the cellular level. An oxidative stress is a condition of organism when the body basically has too many free radicals. Researches believe that antioxidants and other age-defying compounds help cells prevent harm from free radicals and reduce the impact of aging.
Apart from the antioxidants, some other components in foods can affect aging. Experts affirm that they can be organized accordingly to their impact on inflammation at the cellular level.
 Most dermatologists hold the opinion that all foods set in three categories: pro-inflammatory, neutral, and anti-inflammatory. You can help to slow aging at the cellular level by consuming foods that are anti-inflammatory and rich in antioxidants.
Age-related changes may be abrogated by taking foods and drinks that are rich in a great number of components, including antioxidants, and are anti-inflammatory, like cold-water fish and richly colored fruits and vegetables.
On the other hand, pro-inflammatory foods can quicken aging.
If we consume large amounts of saturated or trans fatty acids, starches, and sugars, insulin levels surge quicken the process of aging.
While the benefits to eating healthy are many, expert note that diet is definitely not the only motive force that affects the process of aging.
Hormones, stress, ultraviolet light, and a weakened immune system also promote aging.
