How a vegan diet can affect your intelligence

A vegan is an individual who avoids animal products, such as meat, eggs, dairy products, and other animal-derived substances. A vegan diet typically includes vegetables, legumes, whole grains, and fruits. Some vegans also avoid products that are processed using animal products, such as refined white sugar and some wines. 

Many vegans also prevent clothing and other items that use animal products, such as leather or silk. The vegan diet has been proven to have many health benefits. A vegan diet typically (not always) is associated with a lower body mass index, lower cholesterol levels, lower blood pressure, lower rates of type-2 diabetes, lower overall cancer rates, and lower overall mortality.

Nutritionists warn that it lacks essential brain nutrients that could undermine our thinking ability.

Today, and especially in Western countries, the number of people who adhere to a vegetarian or vegan diet has increased considerably for health reasons or animalistic causes. According to the BBC, there are more than 375 million vegetarians on the planet in the latest statistics. This diet is shown as a balanced and healthy diet. However, it generates a great controversy in nutrition over the possible deficits of some nutrients.

First, the vegan diet logically encompasses a smaller variety of foods. Therefore, more careful planning of all meals is necessary to cover all the body’s nutrients. As there is no animal input, there is no vitamin B12 essential for the body. Besides, some other nutrients in this diet may be compromised or ingested in insufficient quantity. Examples include calcium, vitamin D, essential fatty acids in fish, and iron.

“A vegan diet could reduce your intelligence. Nutrients of interest include: creatine, carnosine, taurine, omega 3, heme iron, B12, D3, B6, selenium, folic acid and choline. Particularly worrying deficiencies for brain development,” Dr. Paul Mason, an expert in nutrition and sports medicine, has written in a “tweet.”

How can a vegan diet affect your intelligence?

Is it true that a vegan diet can affect your intelligence?

There are many different reasons to cut out animal products from your diet. One of them is that they can affect your intelligence, and it’s no secret how fast the world is growing. 

Nowadays, the number of people adopting veganism is expanding for many reasons. A vegan diet can improve your heart health, prevent cancer, and other health benefits. But is veganism good for your brain? Is it possible that going on a vegan diet can make you smarter? 

The world is facing an obesity epidemic, which has led many people to wonder whether a vegan diet can help. According to some people, the benefits of a vegan diet don’t stop at weight loss. There are also claims that it will increase your brainpower and help you to maintain your mental faculties in old age. 

Reasoning with people who question your diet if you are a vegan

A vegan diet is considered a very healthy diet and is often followed by people who want to adopt a healthier lifestyle. It does not include animal food products. A vegan diet will consist of plant foods and fruits, nuts, grains, vegetables, and legumes. By the definition of a vegan, no animal products are included in their diet. Some people follow this diet because they believe it is the right way to live as a human; others follow it for its health benefits; some do so because they think it will be better for the environment. 

Veganism is a lifestyle that more and more people choose to live by. There are many reasons why people want to go vegan — for health reasons, animal rights, sustainability, or a combination of factors. 

A vegan diet is a “pure” plant diet containing no animal products. Vegans do not eat meat, fish, poultry, or any other products obtained from animals. The word is also often used to refer to lifestyle. 

A higher IQ has been directly correlated with a higher B12 level in the blood.

Vitamin B-12 assists in red blood cell formation, cellular metabolism and helps keep both the nervous system and your DNA healthy

It’s widely known that their parents largely influence a person’s intelligence, but a new study shows that it may also be linked to one’s diet. Researchers at the prestigious Massachusetts Institute of Technology (MIT) discovered that the amount of B12 in a person’s blood had been directly correlated with their IQ.

Most people know that being deficient in vitamins and minerals is terrible for the body, but most people aren’t aware that this also applies to blood levels of B12. A new study has found that the higher a person’s B12 levels are, the brighter they are. The study used participants from around the world, and as it turns out, the average person’s blood level of B12 is the same as in the early 20th century—and the higher a person’s blood level of B12, the higher their IQ.

According to a team that included researchers at the Friedman School of Nutrition Science and Policy at Tufts University, people with low levels of vitamin B12 in their blood have lower IQs than people with normal levels of the vitamin. The researchers also found that B12 is linked with higher cognitive performance in people whose vitamin levels are not yet low but are lower than optimal.

Did the meat make us human?

Apart from these shortcomings, nutrition experts are now raising another issue that can call into question the adequacy of this increasingly booming diet: could this deficiency affect the ability to think?

There’s been intense debate amongst anthropologists about what our early ancestors ate. Some studies even point out that meat consumption is what makes us human.

One reason for this theory is that intelligence needs to be “fed”: the brain devours about 20% of our daily calories, although it only accounts for 2% of our body weight. And what better way to find the wide variety of fats, amino acids, vitamins, and minerals that these organs require than by eating animals, which already include these nutrients?

In 2016, the German Nutrition Society categorically stated that vegan diets are not recommended for children, pregnant or nursing women, and adolescents, supported by a research review 2018. In Belgium, forcing your children to eat a vegan diet can lead you to spend time in prison.

But does it damage our intelligence? The only research was conducted on 555 schoolchildren in Kenya who fed three different types of soup – with meat, milk, or oil – or did not receive soup during seven school periods. You examined them before and after to see how their intelligence evolved.

Better reasoning and arithmetic skill

According to this research, the children who received the soup containing meat daily seemed to have a significant advantage. At the end of the study, they outperformed all other children in a nonverbal reasoning test.

Along with the children who received oil soup, they were also the best in an arithmetic skill test.

This study, while inconclusive, raises some unknowns about whether veganism might be slowing some people’s mental development.

Experts seem to agree that essential brain nutrients don’t exist in plants or mushrooms.

Creatine, carnosine, taurine, EPA, and DHA omega-3 (you can find the third type in plants), heme iron, and vitamins B12 and D3 are generally found naturally in foods derived from animal products. Among other foods, vegan food tends to contain relatively small amounts of these.

The benefits of a vegan diet

What are the benefits of a vegan diet

Are you a vegan or vegetarian? Or are you considering becoming a vegan? If so, you may want to know the health benefits of a vegan diet. I am sure this concerns you, and you have probably seen several arguments for and against a vegan diet. If you want to lose weight, it is essential to understand that there is no one-size-fits-all type of diet; however, there are several advantages to such a diet.

A vegan diet can have many health benefits, depending on how well you plan it. For example, a well-planned vegan diet can provide adequate protein, calcium, and vitamin B12. A poorly designed vegan diet, on the other hand, can leave you lacking in some essential nutrients, like omega-3 fatty acids, iron, zinc, and vitamin B12. A well-planned vegan diet also can be a good choice if you’re concerned about your health. People who eat this way face a lower risk of heart disease, strokes, cancer, and diabetes.

The main principle of veganism is that it rejects all forms of exploitation of animals for human purposes. Many see A vegan lifestyle as a way to respect animals. Also, it protects the environment from destruction and reduces the risk of human diseases caused by eating animal-based foods.

So, is a vegan diet safe?

One of the questions that many people are asked is about eliminating animal products from their diet. The answer can seem complex, but it’s pretty simple. A vegan diet can be safe for you and your family if it’s done right.

Protozoa, Eimeria, and Cryptosporidium are parasites that cause potentially fatal diseases in fish and shellfish. A U.S. Centers for Disease Control and Prevention report indicates that 123,200 parasites from animal-based foods occur yearly in the United States, suggesting a lack of consumer awareness about the risk of foodborne infections. Most patients are caused by eating undercooked or raw fish or shellfish. Examples are sushi or sushi-grade fish — and certain raw vegetables, fruits, and nuts, while others are caused by eating unpasteurized milk products. 

A diet for the smart?

Is the vegan diet a diet for the smart ones?

Surprisingly, another study in the UK concludes that “the higher the IQ, the greater the chances of being vegetarian.” This work was published in the British Medical Journal. In this research conducted 20 years after completing the first IQ tests on children, 366 participants claimed to be vegetarians, although more than 100 said they still ate chicken or fish.

Vegetarian men scored 106 IQ, compared to 101 non-vegetarians. Vegetarian women scored an average of 104 compared to 99 non-vegetarian women. There were no significant differences between those who followed a vegetarian diet with a slit board and those who claimed to eat chicken or fish.

Therefore, vegetarian adults got, on average, five more Intellectual Coefficient (CI) fuckers than they were not.

In short, the “boom” of vegetarians vegans generates numerous medical doubts, and therefore, the option of the flexitarian diet, based on balance, achieves more and more adherents every day.


Can a vegan diet improve brain function?

A vegan diet, rich in vitamins, minerals, and antioxidants, may improve cognitive function by reducing oxidative stress and inflammation in the brain.

Is there a link between veganism and intelligence?

Studies suggest no direct link; however, a well-planned vegan diet can support brain health, possibly influencing cognitive abilities positively.

Does a vegan diet affect memory?

A nutrient-rich vegan diet, with adequate B12, omega-3s, and other essential nutrients, can support memory function.

What nutrients are essential for intelligence on a vegan diet?

Key nutrients include omega-3 fatty acids, B-vitamins, particularly B12, vitamin D, iron, and iodine, which are crucial for cognitive processes.

Can a vegan diet lead to cognitive deficiencies?

If poorly planned, a vegan diet can lead to deficiencies in nutrients like B12 and omega-3, affecting cognition; careful planning can mitigate this risk.


A vegan diet, rich in nutrients and ethical values, might be the smartest move for your gray matter. Studies suggest that plant-based munching can boost brainpower thanks to a cornucopia of vitamins, minerals, and antioxidants. But beware, a poorly planned vegan voyage could lead to nutritional shipwrecks, missing crucial cognitive cargo like B12 and Omega-3s.
