Are Meat Eaters Healthier Than Vegans? Debunking the Myth
As a nutritionist, I am often asked whether meat eaters are healthier than vegans. The answer is not as straightforward as one might think. Both diets can be healthy, but it depends on the individual’s food choices and dietary patterns.
In this article, I will examine the nutritional comparisons between diets, health outcomes and disease risks, and dietary patterns and lifestyle factors to help answer this question.
It is important to note that both diets can meet all of the body’s nutritional needs. A well-planned vegan diet can provide all of the necessary nutrients, including protein, iron, calcium, and vitamin B12.
However, some nutrients, such as vitamin B12 and omega-3 fatty acids, are more readily available in animal-based foods.
On the other hand, meat-based diets can be high in saturated fat and cholesterol, which can increase the risk of heart disease and other health problems.

Nutritional Comparisons Between Diets
As a nutritionist, I have often been asked about the differences in nutrition between meat-eaters and vegans. While both diets can be healthy if well-planned, there are some key differences in the nutritional content of each diet.
Protein Sources
One of the biggest concerns for people transitioning to a vegan diet is where to get their protein.
While meat is a complete protein source, vegans can get their protein from a variety of sources, including nuts, seeds, soy products, and legumes.
In fact, some studies suggest that plant-based protein sources may be better for heart health than animal-based sources.
Vitamin and Mineral Intake
Vegans and meat-eaters have different sources of vitamins and minerals in their diets.
For example, meat-eaters get their vitamin B12 from animal products, while vegans need to supplement or get it from fortified foods.
On the other hand, vegans tend to consume more fiber, vitamin C, and vitamin E than meat-eaters.
To ensure adequate intake of essential nutrients, both diets require careful planning and attention to food choices.
Fats and Cholesterol Levels
Meat-eaters tend to consume more saturated fat and cholesterol than vegans, which can increase the risk of heart disease and other health problems.
However, not all fats are created equal.
Vegans need to make sure they are getting enough omega-3 fatty acids, which are found in fatty fish and some plant-based sources like flaxseeds and walnuts.
Meat-eaters can also choose leaner cuts of meat and limit their intake of processed meats to improve their overall health.
Health Outcomes and Disease Risks – Are Meat Eaters Healthier Than Vegans?
As a health professional, I am often asked about the health outcomes and disease risks associated with different diets. In this section, I will discuss the differences in health outcomes and disease risks between meat eaters, vegetarians, and vegans.
Heart Disease and Blood Pressure
Heart disease is one of the leading causes of death worldwide. A diet high in red and processed meat has been linked to an increased risk of heart disease.
On the other hand, vegetarians and vegans tend to have lower rates of heart disease. According to a study published in the Harvard Health Blog, rates of heart disease were 22% lower in vegetarians compared to meat eaters.
Additionally, rates of heart disease were 13% lower in pescatarians, who eat fish but no other meat.
High blood pressure is another risk factor for heart disease.
According to the same study, vegetarians and vegans tend to have lower blood pressure compared to meat eaters. However, other factors, such as body mass index and physical activity, can also affect blood pressure.
Diabetes and Obesity
Type 2 diabetes and obesity are also major health concerns. A diet high in red and processed meat has been linked to an increased risk of type 2 diabetes and obesity.
On the other hand, a plant-based diet has been shown to decrease the risk of these diseases.
According to a study published in the National Center for Biotechnology Information, a vegan diet decreases the risk of cardiometabolic diseases, such as type 2 diabetes, obesity, and non-alcoholic fatty liver disease.
However, the study also noted that veganism has been associated with adverse health outcomes, namely, nervous, skeletal, and immune system impairments, hematological disorders, and nutritional deficiencies.
Cancer Risks
Cancer is another major health concern. A diet high in red and processed meat has been linked to an increased risk of colorectal cancer. However, the evidence linking meat consumption to other types of cancer is less clear.
According to a study published in the BMC Nutrition, the cardiovascular disease risk factors associated with flexitarian diets (plant-based eating habits with occasional consumption of meat and processed meat products) compared to both vegans and omnivores remain underexplored.
Dietary Patterns and Lifestyle Factors
As a nutritionist, I have been asked many times whether meat eaters are healthier than vegans. One of the factors that can affect health outcomes is dietary patterns, which includes the consumption of animal products.
However, it is important to consider other lifestyle factors that may influence health, such as exercise, smoking, and alcohol consumption.
Exercise and Physical Activity
Regular exercise and physical activity are important for maintaining good health.
According to a study published in the Journal of the American Medical Association, physical inactivity is a major risk factor for chronic diseases such as heart disease, diabetes, and cancer.
Meat eaters and vegans can both benefit from regular exercise, regardless of their dietary patterns.
Smoking and Alcohol Consumption
Smoking and excessive alcohol consumption are two lifestyle factors that can negatively impact health.
According to the Centers for Disease Control and Prevention, smoking is the leading cause of preventable death in the United States, and excessive alcohol consumption can lead to liver disease, cancer, and other health problems.
While there is no clear evidence that meat eaters or vegans smoke or drink more than the other, it is important to note that both smoking and excessive alcohol consumption can increase the risk of chronic diseases, regardless of dietary patterns.
Environmental and Ethical Considerations
Animal Welfare
One of the primary reasons people choose to adopt a vegan or vegetarian diet is due to concerns about animal welfare.
Many vegans and vegetarians believe that consuming animal products is cruel and inhumane, and that it is morally wrong to exploit animals for food.
The ethical considerations surrounding animal welfare are complex and multifaceted. While some argue that consuming animal products is necessary for human survival, others believe that a plant-based diet is not only sufficient but also more ethical.
Sustainability and Food Production
Another important consideration when comparing the health benefits of a vegan diet versus a meat-based diet is the impact of food production on the environment.
According to a study published in the American Journal of Clinical Nutrition, a vegan diet is associated with a lower carbon footprint than a meat-based diet.
This is because animal agriculture is a major contributor to greenhouse gas emissions, deforestation, and water pollution. Additionally, animal agriculture requires significantly more land, water, and other resources than plant-based agriculture.
In terms of sustainability, a plant-based diet is generally considered to be more environmentally friendly than a meat-based diet.
However, it is important to note that not all plant-based foods are created equal. For example, some vegan foods, such as avocados and almonds, require a significant amount of water to produce.
Special Populations and Dietary Needs
Pregnancy and Child Development
For pregnant women, it is important to have a balanced diet that provides all the necessary nutrients for both the mother and the growing fetus.
According to a study published in the Journal of the Academy of Nutrition and Dietetics, a well-planned vegan diet can provide adequate nutrition for pregnant women and their infants.
Pregnant women who follow a vegan diet need to pay special attention to getting enough protein, iron, calcium, vitamin D, and vitamin B12.
Meat eaters may have an advantage in getting these nutrients, as they are more easily available in animal-based foods. However, vegans and vegetarians can get these nutrients from fortified foods and supplements.
For example, fortified plant milks and cereals can provide vitamin B12 and vitamin D, while supplements can provide iron and calcium.
Aging Population
As we age, our nutrient needs may change. According to a study published in the Journal of the American College of Nutrition, older adults who follow a vegetarian or vegan diet may have a lower risk of chronic diseases such as heart disease, type 2 diabetes, and certain types of cancer.
However, older adults may have difficulty absorbing certain nutrients such as vitamin B12 and vitamin D.
Meat eaters may have an advantage in getting these nutrients, as they are more easily available in animal-based foods. However, vegans and vegetarians can get these nutrients from fortified foods and supplements.
For example, fortified plant milks and cereals can provide vitamin B12 and vitamin D, while supplements can provide iron and calcium.
Challenges and Misconceptions
Protein and Nutrient Deficiency
One of the common misconceptions about a vegan diet is that it lacks protein and essential nutrients such as zinc, B12, iron, and calcium.
While it is true that these nutrients are typically found in animal products, it is possible to obtain them from plant-based sources.
For example, beans, lentils, tofu, and tempeh are excellent sources of protein. Nuts and seeds are rich in zinc, and B12 can be found in fortified plant-based milks and cereals. Meanwhile, calcium can be obtained from leafy greens, fortified plant-based milks, and tofu.
It is important to note that nutrient deficiency can occur in any type of diet, not just a vegan or vegetarian one. It is essential to ensure that you are consuming a balanced diet and meeting your daily nutrient requirements, regardless of your dietary preferences.
Social and Cultural Impacts
Another challenge that vegans and vegetarians may face is social and cultural impacts.
In some cultures, meat is a staple food, and it can be challenging to find vegan or vegetarian options when dining out. Additionally, some people may not understand or accept the ethical or environmental reasons for choosing a plant-based diet.
However, with the rise of veganism and vegetarianism, more restaurants and food establishments are offering plant-based options.
It is also essential to communicate your dietary preferences with friends and family to ensure that they understand and can accommodate your needs.
Transitioning to a Plant-Based Diet
As with any major dietary change, transitioning to a plant-based diet can be challenging. However, with the right approach, it can be a smooth and enjoyable process.
Starting a Vegan or Vegetarian Diet
If you’re new to a vegan or vegetarian diet, it’s important to start with the basics.
Begin by incorporating more fruits, vegetables, grains, legumes, seeds, and nuts into your diet. These foods are rich in essential nutrients and can help you feel full and satisfied.
It’s also important to find plant-based sources of protein, such as soy, tofu, beans, and whole grains. These foods can help you maintain muscle mass and keep you feeling energized throughout the day.
Maintaining Variety and Balance
One of the keys to a successful plant-based diet is maintaining variety and balance.
Make sure you’re getting a wide range of nutrients by incorporating a variety of fruits, vegetables, grains, legumes, seeds, and nuts into your meals.
To ensure you’re getting all of the essential nutrients your body needs, consider taking a vitamin B12 supplement. This nutrient is primarily found in animal products, so it’s important for vegans and vegetarians to supplement.
In addition, be mindful of your calorie intake. While plant-based diets are generally lower in calories than meat-based diets, it’s still possible to overeat. Focus on eating whole, nutrient-dense foods and listen to your body’s hunger and fullness cues.
Comparing Long-Term Health Implications
When it comes to the long-term health implications of being a meat-eater versus a vegan, the scientific evidence is mixed.
Some studies suggest that vegans and vegetarians have lower rates of chronic diseases such as ischemic heart disease, type 2 diabetes, and some cancers, compared to meat-eaters. However, other studies have found no significant differences in mortality rates between these groups.
One study published in the EPIC-Oxford cohort found that vegetarians had a lower risk of ischaemic heart disease, diabetes, diverticular disease, kidney stones, cataracts, and possibly some cancers, but a relatively high risk of stroke, compared to meat-eaters.
Meanwhile, a review published in PubMed found that vegetarians have a lower prevalence of overweight and obesity and a lower risk of ischemic heart disease compared to non-vegetarians from a similar background, whereas the data are equivocal for stroke.
It’s worth noting that being a vegan or vegetarian does not automatically mean you will be healthier than a meat-eater. A vegan diet can be just as unhealthy as a meat-based diet if it is high in processed foods and lacks essential nutrients. On the other hand, a well-planned vegan or vegetarian diet can provide all the necessary nutrients for optimal health.
In terms of weight loss and obesity, some studies have found that a vegan or vegetarian diet can lead to greater weight loss and a lower body mass index (BMI) compared to a meat-based diet. However, other studies have found no significant differences in weight loss between these groups.
When it comes to blood pressure and hypertension, some studies have found that a vegan or vegetarian diet can lead to lower blood pressure levels compared to a meat-based diet. However, other studies have found no significant differences in blood pressure between these groups.
