Following three new studies, scientists said consuming apples and tomatoes can help restore lung damage caused by smoking.
Other scientists said eating a daily diet of leafy vegetables reduces brain aging by about 11 years.
A third scientific team said: "Children who eat fish weekly will have better IQ and better sleep.
Apples and Tomatoes
The study from Johns Hopkins Bloomberg School of Public Health in the US found that adults who on average ate more than two tomatoes or more than three portions of fresh fruit a day had a slower decline in lung function. It added that this kind of diet heals damages caused by smoking.
The study concluded that the natural decline in lung function over a 10-year period was slower among former smokers with a diet high in tomatoes and fruits.
The scientists compared those who ate three servings of fruit and two fresh tomatoes a day to monitor the slowing down of lung function, to those who ate less than one serving of fruit and less than a tomato.
The researchers found such positive aspects even in individuals who continued to smoke but ate large amounts of tomatoes, but the result was not the same with other dietary sources such as processed foods containing fruits and vegetables like tomato sauce.
This study is part of another study funded by the European Union on lung aging, with researchers from the Imperial College of Britain, was published in the December issue of the European Respiratory Journal, which is dedicated to respiratory studies.
The researchers published their findings on December 20 in the neurological journal Neuroscience of the American Academy of Neurology.
