2. Concerns over Estrogen-like Compounds
Consuming soy-based products as the primary source of protein in a vegan or vegetarian diet has raised concerns among some individuals regarding the presence of plant estrogens, which are also known as phytoestrogens. These compounds are structurally similar to our own body’s estrogen and can bind to estrogen receptors, leading some people to worry about their potential effects on hormone levels.
However, scientific evidence shows that phytoestrogens do not have the same effects as human estrogen in the body, and may even have potential health benefits. Studies have suggested that consuming phytoestrogens may lower the risk of breast cancer and heart disease. The amount of phytoestrogens found in soy products and other non-soy plant-based protein sources is not likely to have any significant effect on hormone levels.
For individuals who are still concerned about phytoestrogens, adding more variety to their diet with non-soy plant-based protein sources is a great option. Lentils, chickpeas, and peas are highly nutritious sources of protein that can be used in many different types of dishes. Quinoa, hemp seeds, chia seeds, pumpkin seeds, and spirulina are also great choices that can add both protein and other essential nutrients to the diet.
