Increase the vegetable protein and fiber in your diet by decreasing the amount of saturated fat, cholesterol and animal protein. Switch the beef in your burger to a vegetable or soy-based burger. Soybeans, once considered the domain of vegetarians, are now making their way to meat eaters' plates.
Legumes are rich in protein and low in fat.
The soybean itself contains high amounts of B vitamins, protein, fiber and low amounts of saturated fat and cholesterol. Now compare that with the nutritional content of a hamburger from Burger King. Cindy Raife, owner of the New City Market, says that if you want a meat-tasting vegetable burger, try the Boca and Natural Touch brands. For a grain-tasting vegetable burger, try the Original Garden brand. If taste and nutritional content don't convince you to try a vegetable burger, perhaps the overall health benefits will.
