what is vegan that you can't eat
Veganism is a strict type of vegetarianism that excludes meat and all animal products. Vegans do not eat meat, fish, eggs, dairy products, or any foods containing them. A vegan diet relies on plant-based foods including fruits, vegetables, grains, beans, nuts, and seeds. A vegan diet can be a healthful and nutritionally adequate diet; however, a vegan must make sure they eat enough foods with protein, calcium, iron, vitamin B12, and omega-3 fatty acids.
If you are vegan, you cannot eat fish or shellfish. Seafood contains DHA and EPA, long-chain omega-3 fatty acids that can lower your risk for heart disease. You can get short-chain omega-3 fatty acids from some plant-based foods, including canola oil, flaxseeds and walnuts.
