5 Dangers Of Being A Vegan

Last Updated on Mar 24, 2024 by HappyDieter

Different societies offer answers about what humans, as omnivores, and meat eaters, need to eat. Many vegetarians as a source of protein consume at least an egg. Because a vegan diet is not adequate in the long run, there are no vegan societies. This highlights some of the potential dangers of being a vegan, as it may lack certain nutrients essential for health if not properly planned.

You can be satisfied when knowing that you are giving your body what it needs by eating nutrients and raw foods to maintain good health, and by making an effort to create variety in your food consumption. These are the main dangers of being a vegan:

Key Takeaways

  • Ensure you supplement with B12 vitamins if you follow a vegan or vegetarian diet to prevent deficiencies in nutrients.

  • Incorporate plant-based protein sources like legumes, tofu, and quinoa to avoid protein deficiency among vegans and vegetarians.

  • Include sources of healthy fats such as avocados, nuts, and seeds in your vegan diet for overall health.

  • Consume fortified foods or consider supplements to meet the requirements for vitamins A and D as vegans.

  • Address digestive issues by gradually introducing high-fiber foods and staying hydrated to support gut health.

1. Lack of B12 vitamins

B12 vitamin is found only in meat and necessary minerals like zinc and calcium. Especially for newborns when there is a deficiency of these nutrients present, they have a big chance to develop nerve damage, retarded growth, rickets, low energy, and problems with lack of calcium that may cause osteoporosis. Even though we can get B12 through eating food supplements, it is not efficient and beneficial enough because we are not vegans getting it naturally,

2. Protein deficiency

Protein deficiency is the biggest risk for vegans eating a soy diet. There are proteins from the “first-class” that we get by consuming eggs, meat, and milk, and “second-class” proteins that come from vegetables, fruit, and soy. Even though there are many plant protein sources, most people don’t cover their protein needs because they don’t include enough variety of foods.

Especially when it comes to babies. Responsible vegan parents know that breast milk is ideal because vegans eating it contains many valuable nutrients, including immune and growth factors and cholesterol (which babies use to make nerve cells). Studies show that vegan breast milk lacks enough docosahexaenoic acid which is vital as it is for brain development and eyes.

3. Lack of healthy fats

Fats are very important because without healthy fats our brains don’t work properly and our skin becomes wrinkled and dry. It is not enough for vegans to consume just seeds and nuts but also fish oil because it provides the fatty acids that are so vital for healthy skin and brain function.

4. Lack of vitamins A and D

Vitamin A andVitamin D are highly important in our body because they are responsible for hormone balance, digestion, immune regulation, and fertility. Meat resources like pastured egg yolks and liver provide true vitamins and vegetables provide carotene, a precursor to vitamin A. Also, only in meat products can be found natural or usable vitamin D. The stories about that we can find vitamin D from mushrooms are just a myth.

5. Digestive issues

People are omnivores so we don’t have the digestive system same as herbivores. Vegan people who only eat plants have extremely limited muscle mass. Unless we eat concentrated sources of protein, we are simply unable to build a lot of lean mass. Proper digestion starts with the production of strong stomach acid that sets the stage for the digestive process which is pH-driven. If juices are not stimulated naturally and regularly, the digestion system weakens and absorbs fewer nutrients than it should.


In a nutshell, being a vegan can lead to deficiencies in essential nutrients like B12, protein, healthy fats, and vitamins A and D. These deficiencies can cause various health issues, including digestive problems, which are some of the dangers of being a vegan. To ensure you maintain a balanced diet as a vegan, consider incorporating supplements or fortified foods to meet your nutritional needs adequately.

Remember, taking care of your health is crucial regardless of your dietary choices. Consult with a healthcare professional or a registered dietitian to create a personalized plan that ensures you get all the necessary nutrients for your body’s optimal functioning. This is especially important considering the potential dangers of being a vegan, such as nutrient deficiencies. Always prioritize your health and well-being.


Are B12 supplements necessary for vegans?

Yes, B12 supplements are essential for vegans as this vitamin is mainly found in animal products. A deficiency can lead to fatigue and nerve damage. Consult a healthcare provider for appropriate supplementation.

How can vegans ensure they get enough protein?

Vegans can meet their protein needs by consuming plant-based sources such as legumes, tofu, tempeh, quinoa, and nuts. Combining different plant proteins throughout the day helps ensure all essential amino acids are obtained.

What are some healthy fats that vegans can include in their diet?

Healthy fats for vegans include avocados, nuts, seeds, and olive oil. These sources provide essential fatty acids like omega-3 and omega-6 which support brain health and reduce inflammation in the body.

Can vegans obtain enough vitamins A and D from plant-based sources?

Vitamin A can be sourced from orange vegetables like sweet potatoes and carrots while vitamin D can be obtained through fortified foods like plant-based milks or supplements. Adequate sunlight exposure also aids in vitamin D synthesis.

How can vegans manage digestive issues associated with their diet?

To manage digestive issues, vegans should gradually increase fiber intake by eating to allow the gut to adjust. Drinking plenty of water, consuming fermented foods like sauerkraut, and seeking guidance from a healthcare professional can also help alleviate digestive discomfort.
