It's often said that plant proteins contain no essential amino acids, but this is not true.
In fact, the majority of plant proteins contain 20 amino acids, but tend to have limited amounts of certain essential amino acids.
This in no way detracts from their health benefits, particularly in reducing the risk of cardiovascular disease and diabetes. They are also a good way to vary protein sources.
All in all, the benefits of plant proteins are very similar to those of a classic whey.
Here are a few tips for adapting your diet without meat sources:
Plant proteins: opt for legumes (beans, lentils, chickpeas), soy-based products (tofu, tempeh, edamame), nuts, seeds and whole grains (quinoa, buckwheat).
Combine your plant proteins with carbohydrates: Legumes are an incomplete source of protein, lacking an amino acid found in carbohydrates. You therefore need to add carbohydrates to your meals. You can add rice, wholegrain pasta, wheat, etc.
Iron-rich foods: include green vegetables such as spinach, kale, dried fruit (apricots, prunes) and quinoa. To increase iron absorption, eat foods with a source of vitamin C, such as citrus fruits or peppers.
Sources of calcium:
For a vegetarian diet: dairy products such as milk, Greek yoghurt, cottage cheese, goat's, sheep's or cow's cheese.
For a vegan diet: use alternatives such as soya milk, oilseeds such as almonds, tofu, falafel, citrus fruit, peppers, etc.
Vitamin B12: include cereals, tofu, tempeh, shiitake mushrooms, yeast spreads and nutritional yeast.
Omega-3 fatty acids: flaxseeds, chia seeds, walnuts and rapeseed oil will give you an adequate supply of essential fatty acids.
By carefully planning your diet and choosing your foods, it's perfectly possible to follow a vegetarian or vegan diet and still get an optimal protein intake! So don't neglect your protein intake, and create an optimal food plan for yourself!
