Veganism and Health

Many people worry that a vegan lifestyle might lack essential nutrients like protein, iron, and B12, but the reality is, those fears are completely unnecessary. Veganism is not only the healthiest choice, but it also provides everything your body needs. Protein is abundant in delicious plant-based foods like mock meats, lentils, chickpeas, tofu, and quinoa. Iron can easily be sourced from spinach, beans, fortified cereals, and pumpkin seeds, making it just as accessible as any other diet. Other important nutrients, such as vitamin B12 and omega-3 fatty acids, can be found in seaweed, fortified foods, or supplements, ensuring that every part of your body is nourished.

So, let’s dive deeper into how adopting a vegan lifestyle will benefit your health and well-being!

What The Health
This eye-opening film uncovers the corruption within the food and healthcare industries, showing how government policies often prioritize profit over public health. What The Health reveals the damaging effects of processed meat, dairy, and animal products on the body, making a persuasive argument for transitioning to a plant-based lifestyle to prevent disease and boost well-being.

The Medical Community’s Take

You might not know it, but a significant shift is occurring within the medical community, with an increasing number of doctors advocating for plant-based diets, due to their profound health benefits and potential to prevent and manage chronic diseases.

A recent
article in The Independent reported on doctors calling for the UK government to stop promoting meat and dairy as essential for health. They argue that such recommendations are misleading and do not align with the latest scientific evidence.

Did you know that the Dr. Tedros Adhanom Ghebreyesus, the Director-General of The World Health Organisation (WHO), has emphasized the necessity of transitioning to plant-based diets to improve both human health and environmental sustainability? He pointed out that food production, particularly animal agriculture, is a significant contributor to global greenhouse gas emissions and the global burden of disease​.

And did you also know that two of the largest and most respected nutritional organizations, The Academy of Nutrition and Dietetics and the British Dietetic Association, affirm that vegan diets are suitable for all stages of life? These include pregnancy, lactation, infancy, childhood, adolescence, and older adulthood, and they can provide all necessary nutrients if properly planned​, just like all diets.

Health Benefits

Cardiovascular Health: Studies have consistently shown that plant-based diets are linked to lower blood pressure, reduced cholesterol levels, and a decreased risk of heart disease. A comprehensive review of 48 studies found that vegetarian and vegan diets are associated with significantly lower risks of heart disease, gastrointestinal, and prostate cancers​.

Cancer Prevention: Plant-based diets, rich in antioxidants, fiber, and phytonutrients, have been shown to reduce the risk of various cancers. The review highlighted that these diets are associated with a reduced risk of metabolic diseases and cancers due to their impact on key health markers like blood pressure and cholesterol​.

Diabetes Prevention: a vegan diet improves insulin sensitivity due to the high fiber content, which helps regulate blood sugar levels. It also tends to have a lower glycemic load, promoting stable blood sugar. Additionally, plant-based diets are associated with better weight management, reducing the risk of obesity—a major risk factor for diabetes. They are low in saturated fats and rich in anti-inflammatory foods, both of which improve metabolic health and reduce insulin resistance. Studies, including the Adventist Health Study-2 and EPIC-Oxford, support these benefits, showing significantly lower diabetes risk among those following a vegan lifestyle.

GP Advice

Many people might, understandably, be sceptical about switching to a plant-based diet, especially if their general practitioners (GPs) have traditionally recommended meat for iron and dairy for calcium. However, it is worth remembering that many regular GPs are not nutritionists. They receive minimal nutrition training—often only about 24 hours throughout their entire education.

One major example that highlights this issue is, as we’ve just mentioned: dairy. It’s no coincidence that the countries with the highest dairy consumption also have some of the highest rates of osteoporosis. I know, right? How can this be, when doctors are so vocal about dairy being essential for bone health?

While dairy products are rich in calcium, the human body does not efficiently absorb it. According to Harvard Health, only about 30% of the calcium in dairy is absorbed by the body. The consumption of all animal protein, be it dairy, meat, or eggs, causes your body to leach calcium from your bones, which is then excreted through urine. This is because animal protein is too acidic for our bodies. Because of this, it has to find a way to neutralize that acidity and fast, and our bone density is the cost, putting people at higher risk of developing conditions like osteoporosis and developing sometimes fatal fractures in later life.

It can feel so scary, having lived your whole life believing in one thing, believing in the knowledge of certain individuals, only to be told something completely contradictory. You feel betrayed, confused. We get it. Every vegan has been there, and it is indeed terrifying. But these are the very real facts, and very real consequences of consuming meat and other animal products.

Animal Products: The Health Risks

Meat

Consuming meat comes with alarming health risks that many people may not realize. Meat can harbour parasites like tapeworms, and the curing process doesn't change the fact that you're essentially eating a slowly decaying corpse. Meat takes much longer to digest in the human body, leading to digestive issues. Animal Protein is also highly acidic to us and contributes to clogged arteries, high blood pressure, and heart disease. Animals raised in unsanitary, dark, and stressful environments - which make up the majority - are often riddled with infections, diseases, tumours, and stress hormones, which you absorb when consuming their meat.

Additionally, widespread use of antibiotics in animal farming increases the risk of antibiotic-resistant bacteria, adding to the health dangers.

Eggs

Consuming eggs also presents several health concerns. Eggs are often contaminated with harmful bacteria like Salmonella, and even organic or free-range eggs are not exempt. Eggs are also high in cholesterol, which can contribute to heart disease and clogged arteries. Furthermore, the protein in eggs, like all animal proteins, contributes to an acidic environment in the body, weakening bone density over time. The conditions in which hens are kept lead to substantial antibiotic use, promoting antibiotic resistance in humans.

Dairy

Consuming dairy products comes with its own set of concerning health risks. Milk, especially organic, can contain pus and blood from cows due to infections, and this is legally allowed up to a certain limit. The acidic nature of animal protein weakens your bone density, increasing the risk of osteoporosis. Additionally, antibiotics used in dairy farming contribute to antibiotic resistance, while the hormones intended for baby calves disrupt human bodies. These hormones often exacerbate menstrual issues, acne, and inflammatory conditions like arthritis, making dairy consumption harmful in more ways than one.

Fish

Consuming fish comes with serious health risks due to contamination with heavy metals and toxins. Large predatory fish like tuna, swordfish, and sharks can accumulate dangerous levels of mercury, leading to neurological and developmental problems, particularly in pregnant women and children. Fish also contain plastic compounds, PCBs, and hexachlorobenzenes (HCBs), which are linked to cancer, liver disease, and reproductive issues. Farmed fish often suffer from diseases and parasites, are treated with antibiotics and chemicals, and contain artificial coloring. While fish provide omega-3s, the contaminants far outweigh the benefits, and cleaner sources like algae offer a safer alternative.

Common Health Objections, Answered:

“Humans are natural omnivores."

Humans are actually anatomically closer to herbivores than omnivores. Our closest living relative, the chimpanzee, consumes plants almost exclusively, with them making up over 97% of their diet. These animals suffer from far fewer diseases than humans and possess strength far superior to ours. Plus, our teeth, jaw movement (in the sense that we grind our food with our teeth, as opposed to rip and swallow), and incredibly long intestines are designed to process plant-based foods. Unlike true omnivores and carnivores, we lack sharp claws and have a far less acidic stomach, which makes digesting meat far more difficult than it is for, say, a lion to.

"We have canine teeth."

Human canines are small and blunt, better suited for biting into fruits and vegetables rather than tearing flesh. Many herbivores, like gorillas and hippos, have far bigger canines but primarily eat plants, proving canines are not exclusive to meat-eaters.

"Our ancestors ate meat, so we should too."

Early humans consumed meat opportunistically rather than as a dietary staple. Modern nutrition science shows that a vegan diet provides all necessary nutrients, offering health benefits and reducing the risk of many chronic diseases. Besides, we have moved on in so many ways since then. Just because our ancestors did something, it doesn’t make it morally right, does it? Our ancestors also kept slaves, owned wives like property and hung people for their sexuality - should we have continued to do all those things?

"Humans need animal protein for muscle growth."

Plant proteins are more than sufficient for building and maintaining muscle. Many athletes and bodybuilders thrive on plant-based diets, as seen in the documentary Game Changers, demonstrating that plant proteins provide all necessary amino acids. Studies show that vegans often have greater stamina and faster recovery times than most meat-eaters.

"Vitamin B12 can only be obtained from animal products."

Vitamin B12 is actually produced by bacteria, not animals. Animals are frequently injected with B12 themselves, so by not eating them, you’re simply cutting out the middle man, as well as a whole host of harmful things. B12 is readily available through fortified foods, like vegan milk, cheese and supplements.

"Humans have always hunted and eaten animals."

Historically, animal consumption was a survival strategy. Modern humans now have access to supermarkets, where there are a variety of plant foods that meet all our nutritional needs. Plus, it’s healthier, more sustainable, and ethical.

"Our digestive system is designed to process meat."

While humans CAN digest meat, it struggles to do so. As stated in the information above, the consumption of any animal protein causes your body to leach calcium from your bones, because it is too acidic for us. Also, our long intestines and less acidic stomachs are, scientifically-speaking, more suited for a plant-based diet. A lion, by comparison, has much shorter intestines, so that the meat is digested quickly. In humans, it takes a long time to break down. This is linked to numerous health issues, including heart disease, cancer, and diabetes.

"A vegan diet lacks essential nutrients."

Any individual’s poor dietary choices can lead to poor health - it has nothing to do with the diet itself - particularly if the person following it lives on only chips and lettuce leaves. But a varied diet rich with animal product alternatives, grains, fruit and vegetables provides all essential nutrients, including protein, iron, calcium, omega-3 fatty acids, and vitamins.

Our Closest Living Relatives

Chimpanzees, our closest living relatives, offer compelling evidence that humans are naturally inclined toward a plant-based diet. In Michael Bluejay's article, the comparison between human anatomy and herbivorous animals shows clear similarities, from jaw structure to digestive processes. Chimpanzees, whose diet is 95-99% plant-based, with only a small percentage coming from insects like termites, demonstrate that even animals with "canine" teeth are predominantly plant eaters. This suggests that humans, with similar biological traits, thrive best on a plant-focused diet.
