How does Nutrition Affect your Lifespan?

As we grow, our nutrition changes accordingly, and it is no surprise that different age groups have varied nutritional needs. Foods play a major role in a person’s health and maintaining their immunity. Humans are busily unveiling the best dietary methods, heath routines and more to prolong our lives. 

Life expectancy is an important topic that piques the interest of the masses. So, here’s how food research can help increase our lifespan:

A Changing World

The world has changed in various ways, including our nutrition needs. Noe people are more inclined to diets and supplements than actual food consumption. Such practices are useful for meeting the nutrition needs of the current lifestyle. But, a healthy diet is more effective for longevity than any number of supplements.

Lean Is Key

A study conducted on Nutrition Research on Centenarians (People over 100 years old) at Boston University showed that most are lean, especially men. Another notable factor for longevity is beating obesity.

Drink Water

Most of us have heard this or heard this about multiple times a day. But it is scientifically proven that drinking plenty of water and a good diet helps flush out toxins, keeps you hydrated and makes the skin healthier.

Seeing Green

Eating green vegetables is very beneficial for detoxification and helps improve eyesight. Lutein is a type of chemical found only in green leafy vegetables that helps sharpen vision and slows down the progression of ageing eyesight issues.

The Big Picture

Eating healthy has many benefits, from reducing disease prevalence to maintaining a healthy lifestyle. When we eat well, stay hydrated, and manage our lifestyle-oriented stresses better, we will surely live longer and healthier.
