I have done some research for one of my class this semester regarding the relationship between aging and food consumption. The results came out really surprising. One finding suggested that eating less calories could slow your aging process. Second, less food could reduce your of risk of developing major health problems such as cardiovascular diseases, diabetes, and memory loss.
But a recent study conducted at the Institute of Healthy Aging at University College London, found that eating less “protein” could slow your aging process and make you live longer life. These are new findings, and scientists have always thought that “calorie restriction” is the key to longer life. But the study still believe that reducing calories by as much as 30 per cent could reduce risks of developing heart disease or cancer by half and increase lifetimes by nearly a third.
The study leader, Dr Matthew Piper said ” vegetarian diet could be one way to achieve the effect”.
Dr. Matthew has also said that eating protein is necessary, but you have to balance your intake.
So, What does all that mean?
That means that by reducing foods that contain the protein – such as meat, fish and certain nuts – people should live longer without the need to cut down on meals.
