Low protein diet for longevity

Having a low-protein diet early in life may help you live longer. A study found fruit flies which share more than two thirds of humans genes live twice as long when given minimal protein diet at tender age. A typical western diet is high in protein and fats from meat, diary, and eggs with red meat in linked to heart disease and cancer. There is an evidence that eating too much protein long-term can lead to an increased risk of osteoporosis and kidney problems.

The researchers also believe their findings could be explained because a low-protein diet produces less toxic lipids secreted by the skin. Health skin lipids form a natural barrier keeping out dirt, impurities and harmful chemicals that can accelerate ageing. Scientists used the fly drosophila melanogaster to understand how diet in early life acts to alter lifespan. These insects are used in lifespan experiments because it lives for only two to three months.

The team stressed that there was enough evidence to recommend pregnant women go on low-protein diets to boost their unborn child's health. There is evidence in humans and other mammals that a mother's diet can alter the risk of her offspring developing cardiovascular disease and diabetes later in life, but the genetic processes underlying this effect remain to be identified.

Effects of father's diet on fetus

Father's diet before conception can impact newborn's health, low carbohydrate and high protein diet can make the fetus healthy. Experiments were performed on fruit flies and the results showed offspring were less likely to survive if their fathers consumed a poor diet of high carbohydrates and low protein.

The insects were used because they have 60 percent of human genes.
Researchers mated male fruit flies with females after they altered their diet.
Since fruit flies share similar genes to that of humans, the researchers believe the impacts of the bugs' diet would correlate with that of men.

The study claims that men who want to become fathers should have a diet consisting of fish, meat, vegetables and fruit while cutting out pasta, rice and white bread. Sugary foods such as sweets, cakes and biscuits should be avoided. Exposure to toxins can be passed from the father to his offspring through his semen. During the experiment, female fruit flies were fed the same diet while males had different ones consisting of yeast and sugars.

The insects ate different foods, from low to high concentrations of proteins, carbohydrates and calories. After some days the males were mated with two females. The results showed that embryos were more likely to survive if they had a father with a high protein and low carbohydrates diet. Mortality was highest for offspring of males given a high carbohydrate, low protein diet. Researchers also found a connection between the male's body condition and his offspring's mortality.
