Overall, diets that include meat are the most common worldwide according to the results of a 2018 Ipsos MORI study of 16–64 years olds in 28 different countries. Ipsos states “"An omnivorous diet is the most common diet globally, with non-meat diets (which can include fish) followed by over a tenth of the global population."” Approximately 87% of people include meat in their diet in some frequency. 73% of meat eaters included it in their diet regularly and 14% consumed meat only occasionally or infrequently. Estimates of the non-meat diets were also broken down. About 3% of people followed vegan diets; where consumption of meat, eggs, and dairy are abstained from. About 5% of people followed vegetarian diets; where consumption of meat is abstained from, but egg and/or dairy consumption is not strictly restricted. About 3% of people followed pescetarian diets; where consumption of the meat of land animals is abstained from, fish meat and other seafood is consumed, and egg and/or dairy consumption may or may not be strictly restricted.
