what do plants contain
Plants contain (actually, they manufacture them) many oils and sugars which animals (actually, mammals - don't know if other vertebrates and invertebrates store fat in the same way) eat and then process to use for fuel. Unused portions are stored in the body in the adipose tissues. So, while plants contain the basic ingredients of what we think of as fat, they don't store them in any kind of fatty tissue the way animals do, in what we think of generically as fat.. Plants don't eat a diet high in anything, good or bad.
