Vegan Lifestyle and Nutrient Deficiencies – Myth or Reality?

Vegan Lifestyle and Nutrient Deficiencies

More and more people are adapting to a fully vegan lifestyle nowadays. In the United States, there are 6.5 million people who identify themselves as proud vegans. This increasing number of people turning vegan distinctly depicts that veganism has been successful in waking up the ethical and pure side of humans.

More people have started believing in an organic lifestyle that would not cause blood to shed, which would not be the reason for murder.

Apart from the conscience of human’s veganism deals with, it also directly points out the unhealthy aspects of carnivorous diets. The meat, fish, poultry people love to eat are fetching them into the dungeon of severe health problems, some of which are life-threatening. On the other hand, nature has only good to offer us.

But there is another less-discussed aspect of veganism. There are high chances of lacking some of the essential nutrients in a vegan diet.

Heather Fields, M.D of Community and Internal Medicine at Mayo Clinic in Arizona, says, “We found that some of these nutrients, which can have implications in neurologic disorders, anemia, bone strength and other health concerns, can be deficient in poorly planned vegan diets.” This is the say of many people out there.

But there lies a simple thing which we often tend to ignore. Vegan nutrient deficiencies associated with a plant based diet occurs when someone has not researched enough about what veganism has to offer. That’s why people who want to embark on this way of vegan life need to know about what nutrients vegans lacks and other common deficiencies in vegans.

As veganism is a lifestyle, one cannot jumpstart into it. The person needs to go through a lot of reading and talking to other vegans to be fully prepared and knowledgeable about it.

Today’s article is going to address all the matters related to vegan nutrient deficiency symptoms and what vitamins do vegans tend to lack. It will concentrate on bringing the effect of various nutrients on our bodies, their common sources, as well as vegan foods containing the nutrients and vegan supplements. Let’s begin the journey of knowledge then!

Benefits of the Plant-based Diet

A vegan lifestyle showers one with a great many health benefits. Most people get to know that veganism is linked with weight loss, but there are other science-based health benefits of the plant-based diet, which some people often tend to ignore.

1. Weight Loss

Weight loss can be a driving force behind a lot more Americans choosing a vegan diet. Vegans tend to have lower BMIs, Body Mass Indexes than non-vegetarians or vegetarians. This is due to the low-fat content and excellent amino acid profile of vegan foods, which provide sufficient energy without contributing to fat build up in your body.

2. Lowers Blood Sugar Level and chances of Heart Diseases

Several observational studies show that vegans have higher insulin sensitivity and lower blood sugar levels than people who follow the omnivorous diet. This is linked with reducing the chances of various heart diseases as it decreases blood pressure.

3. Improves Kidney Functions and Digestion

Many doctors tend to prescribe their patients to follow a vegan diet who are especially suffering from diabetes. A proper vegan diet improves Kidney functions. And because of the high fiber content, it enhances your digestion and perfects any irregular bowel movement.

4. Prevents Type 2 Diabetes and many types of cancers

Type 2 Diabetes is an emerging issue among Americans. Veganism helps prevent this. Vegans eat more vegetables, legumes, and fruits. Consuming legumes on a daily basis reduces the risk of colorectal cancer. Avoiding meat and dairy products also lower the risk of prostate cancer.

According to various studies, vegans eat more fiber, antioxidants, vitamins, and minerals, magnesium, potassium, and folate compared to non-vegans. This wholesome nutrient profile of a proper vegan diet helps one reduce the risks of several life-threatening diseases such as cancer and type 2 diabetes. Cutting off processed meat and dairy products from your diet and including more and more plant-based goodness is certainly a way of living a healthier, disease-free, and longer life.

Common Deficiencies In Vegan Diet (Nutrients Vegans Lack)

Common Vegan Dietary Deficiencies

Despite the huge amounts of essential nutrients veganism offers, a poorly planned vegan diet routine can also push you towards many health issues. Vegan dietary deficiencies mainly happen because of a lack of knowledge and loads of misconceptions. There are some common deficiencies in vegan diet, such as vitamin B12, vitamin D, calcium, iron, zinc, creatine, and long-chain omega 3s.
