Introduction
Adopting a vegan lifestyle has numerous benefits, including improved heart health, weight management, and a lower risk of certain diseases. However, vegans need to be mindful of their nutrient intake, particularly when it comes to vitamins. In this article, we’ll explore the eight vitamins that vegans may be missing out on and how to include them in a plant-based diet.
1. Vitamin B12
Vitamin B12 is crucial for nerve function and the production of DNA and red blood cells. It’s primarily found in animal products, which can make it challenging for vegans to obtain sufficient amounts.
Sources for Vegans: Fortified plant milks, nutritional yeast, and B12 supplements.
2. Vitamin D
Vitamin D is essential for bone health and immune function. The primary natural source of vitamin D is sunlight, but it can also be found in animal products.
Sources for Vegans: Fortified plant milks, fortified orange juice, mushrooms exposed to sunlight, and vitamin D supplements.
3. Omega-3 Fatty Acids
Though not a vitamin, omega-3 fatty acids are essential nutrients that support heart and brain health. They are predominantly found in fish and other seafood.
Sources for Vegans: Flaxseeds, chia seeds, hemp seeds, walnuts, and algae-based supplements.
4. Iron
Iron is vital for transporting oxygen in the blood. While plant-based sources of iron exist, they are not as readily absorbed by the body as animal-based sources.
Sources for Vegans: Lentils, chickpeas, beans, tofu, quinoa, spinach, and fortified cereals. Pairing these with vitamin C-rich foods can enhance absorption.
5. Calcium
Calcium is necessary for strong bones and teeth as well as muscle function. Dairy products are the most well-known sources of calcium, but vegans need to find alternatives.
Sources for Vegans: Fortified plant milks, tofu, almonds, sesame seeds, tahini, and leafy green vegetables like kale and bok choy.
6. Zinc
Zinc supports immune function and DNA synthesis. Plant-based sources of zinc are often less bioavailable than animal sources.
Sources for Vegans: Legumes, chickpeas, lentils, tofu, nuts, seeds, and whole grains.
7. Iodine
Iodine is essential for thyroid function. While iodized salt is a common source, many health-conscious vegans may opt for other types of salt.
Sources for Vegans: Iodized salt, sea vegetables like seaweed, and iodine supplements.
8. Vitamin K2
Vitamin K2 is important for bone and heart health. It is primarily found in animal products and fermented foods.
Sources for Vegans: Fermented foods like natto, sauerkraut, and some vegan supplements.
