Soon, genetic testing may identify what diet you should consume for a longer, healthier life.

Researchers have identified a group of genes that allow an organism to adapt to different diets and show that without them, even minor tweaks to diet can cause premature aging and death.

“The studies have revealed that single gene mutations can alter the ability of an organism to utilise a specific diet. This could explain why certain diets work for some but not others,” explained Sean Curran, assistant professor at University of Southern California (USC).

In the age of commercial gene sequencing, people might be able to identify which diet would work best for them through a simple blood test, added Shanshan Pang from USC.

They studied caenorhabditis elegans – a one-milimetre-long worm that scientists have used as a model organism for years.

Curran and Pang identified a gene called ‘alh-6’ which delayed the effects of aging depending on what type of diet the worm was fed by protecting it against diet-induced mitochondrial defects.

“What we have learned in the worm could translate to a better understanding of the factors that alter diet success in humans,” Curran said in the study appeared in the journal Cell Metabolism.

Finding a genetic basis for an organism’s dietary needs suggests that different individuals may be genetically predisposed to thrive on different diets.

This could be the start of personalised dieting based on an individual’s genetic makeup, Curran stressed. (IANS)

A Diet Rich in Nutrients Helps In Living Longer: Study

Anti-inflammatory foods consist of fruits and vegetables, tea, coffee, whole grain bread, breakfast cereal, low-fat cheese, olive oil.

Adhering to a diet rich in fruits, vegetables, whole grain bread, nuts, olive oil and canola oil may help you live longer, a new study has found.

The findings, published in the Journal of Internal Medicine, suggest that those who closely follow an anti-inflammatory diet have an 18 per cent lower risk of all-cause mortality.

The researchers also found that those who follow the diet experience a 20 per cent lower risk of cardiovascular mortality, and a 13 per cent lower risk of cancer mortality, when compared with those who followed the diet to a lesser degree.

“Our dose-response analysis showed that even partial adherence to the anti-inflammatory diet may provide a health benefit,” said lead author Joanna Kaluza, Associate Professor at the Warsaw University of Life Sciences in Poland.

It was also found that smokers who followed the diet experienced even greater benefits when compared with smokers who did not follow the diet, the team said.

For the study, the research team involved 68,273 Swedish men and women aged between 45 and 83 years. The participants were followed for 16 years.

The anti-inflammatory potential of the diet was estimated using the validated anti-inflammatory diet index (AIDI), which includes 11 potential anti-inflammatory and five potential pro-inflammatory foods.

Anti-inflammatory foods consist of fruits and vegetables, tea, coffee, whole grain bread, breakfast cereal, low-fat cheese, olive oil and canola oil, nuts, chocolate, and moderate amounts of red wine and beer.

Pro-inflammatory foods include unprocessed and processed red meat, organ meats, chips, and soft-drink beverages, the team said. (IANS)
