" Overall, it is fair to say that any plant-based food has many more similarities in terms of nutrient compositions to other plant-based foods than it does to animal-based foods. The same is true the other way
around; all animal-based foods are more like other animal-based foods than they are to plant-based foods.
As you can see, plant foods have dramatically more antioxidants, fiber and minerals than animal foods. In fact, animal foods are almost completely devoid of several of these nutrients. Animal foods, on the other hand, have much more cholesterol and fat. They also have slightly more protein than plant foods, along with more B]2 and vitamin D, although
the vitamin D is largely due to artificial fortification in milk.
But if one looks a little more closely,
the fat and the protein of nuts and seeds are different: they are more healthful than the fat and protein of animal foods. They also are accompanied
by some interesting antioxidant substances "
