How Eating a Vegetarian or Vegan Diet Can Lead to Nutrient Deficiencies

It is widely known that a vegetarian or vegan diet can be an incredibly healthy way to eat. Plant-based diets are abundant in essential vitamins and minerals and can reduce the risk of many diseases. However, there are some nutrient deficiencies that can arise from eating a vegetarian or vegan diet that could be better known. Here, we will detail the link between vegetarian or vegan diets and nutrient deficiencies, explaining which nutrients may be lacking, as well as how to prevent such deficiencies from occurring.

What Nutrients are often missing in Vegetarian or Vegan Diets?

The nutrients generally lacking in a vegetarian or vegan diet are vitamin B12, vitamin D, calcium, iron, zinc, and omega-3 fatty acids. Vitamin B12 is an essential nutrient for nerve health, and it can only be found in animal-based foods. Vegans lack a consistent source of this Vitamin, so much supplementation is needed. Vitamin D is important for healthy bones and it is found in animal fatty tissue. People eating a vegan diet will likely require Vitamin D supplementation. Calcium needs may be slightly higher in vegan diets, while iron, zinc, and omega-3 fatty acids may also be lacking.

What are the Symptoms of Nutrient Deficiencies in Vegetarians or Vegans?

The symptoms of a nutritional deficiency can vary, depending on the type and severity of the deficiency. For example, Vitamin B12 deficiency may cause fatigue, shortness of breath, constipation, and tingling in the hands and feet. Calcium deficiency can lead to low bone density, weak and brittle bones, joint pain, and osteoporosis. Iron deficiency can cause fatigue, dizziness, and loss of appetite. Zinc deficiency can lead to poor growth, slow wound healing, and anemia. Lastly, Omega-3 fatty acid deficiency can lead to the development of heart disease and depression.

Are These Nutrients Found in Non-Animal Sources?

Yes, there are non-animal sources for all of these essential nutrients. Vitamin B12 is most commonly found in fortified foods such as soy products, nutritional yeast, some breakfast cereals, and some plant milk. Vitamin D can be found in some mushrooms, although supplementation may be necessary. Calcium can be found in leafy green vegetables, fortified plant milk, nuts, and seeds. Iron is primarily found in legumes, beans, and dark green vegetables. Zinc can be found in whole grains, legumes, tempeh, and fortified cereals. Finally, Omega-3 fatty acids are most abundant in flaxseeds, hempseeds, chia seeds, and some algae-based supplements.

How can nutrient deficiencies be prevented in Vegans and Vegetarians?

It is important for those who are vegan or vegetarian to consciously plan and supplement their diets to ensure that all necessary nutrients are being consumed. People following a vegetarian or vegan diet should be mindful of their nutritional status and ensure that they are getting adequate amounts of vitamins and minerals from food sources, or through supplementation if needed. It is also important to speak with a healthcare practitioner to determine which supplements may be needed for an individual's particular circumstances.

Conclusion

Overall, vegetarian and vegan diets can be very healthy and provide essential vitamins and minerals. However, there can be some nutrient deficiencies that come along with these diets, such as Vitamin B12, Calcium, Iron, Zinc, and Omega-3 fatty acids. It is important to plan and supplement one’s diet appropriately and to consult a healthcare professional to ensure that all nutritional needs are being met. With careful thought and planning, it is possible to safely and healthfully follow a vegan or vegetarian diet.
