People who eat plenty of vegetables are up to a third less likely to catch Covid-19.
Vegetarians and vegans are the best protected, but anyone whose diet is mainly made up of vegetables, legumes and nuts also reduces their chances of catching the Covid virus.
Scientists from the University of Sao Paulo in Brazil think the chemicals in plants boost the immune system that naturally protects us against infection.
They analysed the diets of 702 people during the summer of 2022, a third of whom were vegetarian and 87 were ‘flexitarians’ who ate meat on three days or less each week.
Overall, 52 percent of those who were eating meat and dairy caught Covid at some later date, but this happened to just 40 percent of vegetarians. Meat eaters were also more likely to suffer a severe infection, the researchers noted.
