On November 1st, vegans around the world celebrate World Vegan Day, an opportunity to celebrate and promote the benefits of a plant-based lifestyle. A vegan diet offers numerous health benefits, including a lower risk of high blood pressure, heart disease, and diabetes. Some studies even suggest that vegans have a lower risk of certain types of cancer.
Although a vegan diet offers many health benefits, it's important to ensure your body receives all the essential nutrients in sufficient quantities. Some essential nutrients are found primarily or exclusively in animal products.
In this blog post, we will take a look at 9 nutrients that are considered potentially critical for vegans due to their complete avoidance of animal products.
1. Vitamin B12
Vitamin B12 performs several important functions in the body. Among other things, it is important for blood formation and cell division, and for the normal functioning of the nervous system. Vitamin B12 is a key nutrient that vegans should pay particular attention to, as it is mainly found in animal products. Vegans should therefore include fortified foods such as plant-based milk and breakfast cereals in their diet or regularly take vitamin B12 supplements.
2. Vitamin D
Vitamin D is important for calcium metabolism, bone health, muscle function, and the immune system, among other things. It is largely produced through sunlight from cholesterol stored under the skin. Since sunlight in Europe during the fall and winter months is too low for sufficient vitamin D production in the skin, and we also spend less time outdoors than before, vitamin D deficiency is unfortunately widespread in the population.
Vitamin D can also be obtained through diet, but primarily from animal products such as (fatty) fish and, to a lesser extent, meat and eggs. Therefore, vegans and vegetarians should ensure they are exposed to sufficient sunlight or consider taking a vitamin D supplement regularly.
3. Omega-3 fatty acids
The omega-3 fatty acids DHA and EPA belong to the polyunsaturated fatty acids family. DHA and EPA are beneficial for heart health, with DHA also contributing to normal brain function and the maintenance of vision. Although the body can synthesize DHA and EPA to a limited extent from alpha-linolenic acid (ALA), these fatty acids must be obtained additionally through the diet. Since omega-3 fatty acids are mainly found in oily fish, it is advisable for vegans to supplement these fatty acids with vegan supplements.
4. Iron
Iron deficiency is not uncommon among vegans, as plant-based iron sources (non-heme iron) are less easily absorbed by the body than the heme iron found in animal products. Iron is important for, among other things, the formation of hemoglobin in red blood cells, energy metabolism, and the normal function of the immune system.
To meet their iron needs, vegans should eat iron-rich foods such as legumes, whole grains, nuts and seeds, and green leafy vegetables. Combining them with vitamin C-rich foods can improve iron absorption. However, in some cases, iron supplementation may be beneficial.
5. Calcium
Calcium is important for, among other things, the development and maintenance of bones and teeth, energy metabolism, and muscle function. Calcium is found primarily in dairy products, but also in certain vegetables such as spinach and kale.
If dairy products are not consumed, there is an increased risk of calcium deficiency. Vegans can obtain calcium from fortified plant-based milk, tofu, and dark green leafy vegetables, or take calcium supplements .
6. Iodine
Iodine is a trace element essential for the production of thyroid hormone. This hormone is important for growth, nervous system development, and metabolism. Iodine occurs naturally in marine fish, eggs, dairy products, and algae. Iodine is sometimes added to table salt and baker's salt, but this is often not the case with organic or homemade bread.
It's important for vegans to ensure they get enough iodine into their diet, as seafood, a major source of iodine, is not included in the vegan diet. Supplementing with iodine through a dietary supplement may therefore be beneficial.
7. Zinc
Zinc is an essential trace element. It is important for metabolism, the health of skin, hair, and nails, and the healthy functioning of the immune system, among other things. Zinc also acts as an antioxidant, helping to protect cells from oxidative stress.
The largest amounts of zinc are found in animal products such as shellfish, dairy products, and meat. Plant products such as oatmeal, legumes, and nuts also contain zinc, but in smaller amounts. Therefore, taking a zinc supplement as a supplement to a vegan diet can be beneficial.
8. L-Carnitine
L-carnitine is a naturally occurring compound of the essential amino acids methionine and lysine. Tissues that derive their energy from fat, such as heart and skeletal muscle, are particularly rich in L-carnitine.
Although L-carnitine can be produced by the body, it must also be obtained through food. Since L-carnitine is primarily found in animal products such as red meat, fish, poultry, and milk, vegetarians and vegans may be more likely to suffer from a deficiency and may benefit from L-carnitine supplementation .
9. Selen
Selenium is an essential trace element. Even though the mineral is present in only small amounts in the human body, it is vital to our survival.
Selenium plays an important role in the function of antioxidant enzymes and helps protect cells from oxidative stress. It is essential for the healthy functioning of the immune system and contributes to normal thyroid function. Selenium is also important for maintaining healthy skin and hair. Vegans should include selenium-rich foods such as nuts, seeds, legumes, and whole grains in their diet. Selenium supplements can be considered if needed.
Conclusion
On World Vegan Day, we want to emphasize the importance of a balanced and healthy vegan lifestyle. Through careful planning and the use of supplements where appropriate, vegans can ensure they get all the nutrients they need while maintaining an ethical and environmentally friendly lifestyle. Let's use World Vegan Day as an opportunity to spread the word about the benefits of veganism and work together to make the world a healthier and more sustainable place .
