The food we eat influences the lifespan. It is a known fact that eating healthily prolongs the lifespan and keeps diseases away.

Several researchers have done a good job in asserting the importance of healthy eating and how it boosts the immune system against certain immunological diseases.

However, prolonging the lifespan does not just lie with healthy eating but how frequent we eat.

According to research, making amends in food intake frequency can be beneficial to the health.

Researchers and nutritionists often point out the importance of eating a diet that is full of fruits and vegetables, whole grains, nuts, fish, poultry, and vegetable oils.

A research study published in the Journal of nutrition, also revealed that people who eat diets consistent with a healthy dietary pattern had a 31 percent lower risk of heart disease, a 33 percent lower risk of diabetes, and a 20 percent lower risk of stroke.

But then, researchers focus more on the foods we eat and less on the frequency of our eating habits.

While speaking to the, Dr Sarah Brewer, Medical Director of Healthspan and Author of Live Longer, Look Younger, gave an insight into the current research in centered on how the frequency of food intake affects the lifespan.

“Restricting your calorie intake can significantly extend your lifespan, although you may argue that life quality is reduced,” she said.

In Dr Brewer clarification, you will have to limit your calorie intake to 60-70 percent of your regular daily needs to extend your lifespan by 30-50 percent.

This can be difficult, mostly if you have a mentally and demanding lifestyle.

Nonetheless, according to Dr Brewer, eating every other day (i.e. fasting one day, and eating what you like the next) seems to yield the same outcomes with the health benefits starting within as little as two weeks.

This idea is from researchers writing in the journal Medical Hypotheses.

As Brewer narrated, the researchers implied that this method might boost insulin resistance, asthma, allergies, infections, autoimmune diseases (eg asthma, rheumatoid arthritis), osteoarthritis, heart problems and menopausal symptoms.

It may furthermore delay, prevent or improve neurological conditions such as Alzheimer’s, Parkinson’s and multiple sclerosis.

Dr Brewer also pointed out the importance of exercise in prolonging the lifespan.

“Exercise can partially reverse the effects of the ageing process on physiological functions and preserve functional reserve in the elderly,” said Dr Brewer.

“In particular, deaths from coronary heart disease were reduced by 41 percent and risk of stroke reduced by 50 percent,” she said.

According to Dr Brewer, regular exercise can prevent the risk of diabetes and cancers.

“Both the Finnish Diabetes Prevention Study and the Diabetes Prevention Program found that changes in lifestyle of high-risk overweight subjects with impaired glucose tolerance reduced the risk of type 2 diabetes by 58 percent,” she revealed.

The NHS also counseled that adults should do a minimum of 150 minutes (two hours and 30 minutes) of moderate-intensity aerobic activity, like cycling or fast walking, every week.
