A new study suggests people should aim to get more protein from vegetable sources rather than meat, to boost life expectancy. Researchers looked at 30 years’ of diet data for 130,000 people and found a reduced risk of early death in people who ate more plant-based protein, and an increased risk in those who ate more animal protein. The study recommends people should consider eating more plant proteins like nuts or soy, and if you do choose to get your protein from meat, fish and chicken are your best choices.
