Vegans eat larger portions to meet calorie needs, study reveals

A 2021 study involving 150,000 vegans has revealed that those following strict plant-based diets consume larger portions to meet their calorie needs. The research, led by Professor John Drawley of the University of California School of Public Health, also found that participants spent more on non-animal-derived foods than their non-vegan counterparts. The findings highlighted a key difference in eating habits between vegans and other dietary groups. Participants in the study reported buying greater quantities of food to compensate for the lower calorie density of plant-based options. This trend led to higher grocery bills for non-animal products.

Meanwhile, Samuel Maina, a nutritionist and lecturer at Kenya Medical Training College (KMTC) Nairobi campus, has weighed in on the debate. He cautioned against eliminating animal-derived foods purely for ethical reasons. Maina pointed to the nutritional advantages of items like honey, eggs, milk, and blood, arguing that they provide essential health benefits.

The study sheds light on the dietary challenges faced by strict vegetarians, including increased food consumption and costs. Maina's comments add another layer, suggesting that animal products may still play a valuable role in balanced nutrition.
