Five a day: Fruit and vegetables are healthy for all of us, but some people are better equipped than others to synthesize long-chain omega-3 fatty acids from plant-based food.

Fish genes: In Inuit and other populations traditionally relying on seafood, researchers have found gene variants that weaken the endogenous synthesis of the fatty acids that these people take up with their regular doses of fish.

Western diet: Many people of European descent regularly eat large amounts of meat, even though European genomes show a clear selection in favour of genes adapted to a more plant-based diet since the introduction of agriculture.

Fish oil: Long-chain omega-3 fatty acids are widely promoted as healthy nutritional supplements, but in truth a detailed genetic analysis of a given person would be necessary to determine whether such supplements would be good or bad for their health.
