Can I get enough protein eating a plant-based diet?
Not only will you get all the protein you need, for the first time in your life you won’t suffer from an excess of it.
Ample amounts of protein are thriving in whole, natural plant-based foods. For example, spinach is 51 percent protein; mushrooms, 35 percent; beans, 26 percent; oatmeal, 16 percent; whole wheat pasta, 15 percent; corn, 12 percent; and potatoes, 11 percent.
What’s more, our body needs less protein than you may think. According to the World Health Organization (WHO), the average 150-pound male requires only 22.5 grams of protein daily based on a 2,000 calorie a day diet, which means about 4.5 percent of calories should come from protein. (WHO recommends pregnant women get 6 percent of calories from protein.) Other nutritional organizations recommend as little as 2.5 percent of daily calories come from protein while the U.S. Food and Nutrition Board’s recommended daily allowance is 6 percent after a built-in safety margin; most Americans, however, are taking in 20 percent or more.
Doctors from my father to Dean Ornish to Joel Fuhrman, author of the best selling Eat to Live: The Revolutionary Formula for Fast and Sustained Weight Loss (Little, Brown), all suggest that getting an adequate amount of protein should be the least of your worries.
Look around you and tell me the last time you saw someone who was hospitalized for a protein deficiency. Or look around in nature, where you will notice that the largest and strongest animals, such as elephants, gorillas, hippos, and bison, are all plant eaters.
Also, the type of protein you consume is as important as the amount. If you are taking in most of your protein from animal-based foods, you’re getting not only too much protein, but also an acid-producing form that wreaks havoc on your system.
Why is protein so potentially harmful? Because your body can store carbohydrates and fats, but not protein. So if the protein content of your diet exceeds the amount you need, not only will your liver and kidneys become overburdened, but you will start leaching calcium from your bones to neutralize the excess animal protein that becomes acidic in the human body.
That’s why, in the case of protein, the adage “less is more” definitely applies. The average American consumes well over 100 grams daily—a dangerous amount. But if you eat a plant-strong diet, you’ll be getting neither too much nor too little protein, but an amount that’s just right.
