Going 100% Raw Vegan
Raw foods, such as fresh fruits, vegetables and seeds, are certainly nutritious. Eating only raw foods, however, can pose some risks. "A raw food diet can be very healthy," Giblin says, "however, you want to be sure that you are still meeting your nutritional needs." This includes nutrients raw food diets often lack, such as calcium and vitamins B-12 and D, Giblin points out. Consuming too little vitamin B-12, which derives mainly from animal products that are restricted from raw-food diets, can cause fatigue, constipation, appetite loss and numbness. Without enough vitamin D and calcium, which promote bone health, you can develop weak, breakable bones. If you choose to follow a vegan or raw vegan diet, you should consider taking a vitamin B-12 supplement and a vitamin D supplement. You can also produce vitamin D by spending more time in the sun however, it's important to limit exposure of skin to sunlight depending on your skin pigment in order to lower the risk for skin cancer.
