Notice the differences?

A typical vegetarian's diet is high in dietary fibre. Due to the low biological value of plant proteins (in comparison to animal proteins), vegetarians are advised to consume a larger amount of legumes which would have been classified under 'Meat & alternatives' in usual HDP. Therefore, you can see that portions for 'whole grains' and 'legumes' are about the same size as represented graphically in the vegetarian diet pyramid.

Eating too much foods rich in saturated fats and cholesterol (e.g. seafood, meat products) can increase the risk of heart diseases, stroke and some cancers. You may want to know that plant foods are essentially free of cholesterol, so there are indeed some incentives to adopting a rabbit's diet!
