Are Vegetarians More Healthier Than People Who Eat Meat?

3 min read

According to a study published in the Journal of the American Medical Association, vegetarians show a 12% reduction in premature death compared to their meat-eating counterparts. This finding, however, only scratches the surface of the complex nutritional and lifestyle factors that determine if vegetarians are more healthier than people who eat meat.

Quick Summary

This article examines the health outcomes of vegetarian and meat-based diets by reviewing scientific studies on chronic disease rates, nutrient intake, and overall wellness. It highlights both the proven benefits and potential drawbacks of each eating pattern.

Key Points

Reduced Chronic Disease Risk: Studies show vegetarians have lower rates of heart disease, type 2 diabetes, and certain cancers compared to average meat-eaters.
Not All Vegetarian Diets Are Healthy: A diet of processed snacks and junk food, even if meat-free, is not conducive to good health.
Potential Nutrient Deficiencies: Strict vegetarian or vegan diets require careful planning to ensure adequate intake of nutrients like Vitamin B12, iron, and omega-3 fatty acids.
Lower Saturated Fat and Calories: Plant-based diets are typically lower in saturated fat and total calories, which contributes to lower body mass index (BMI) among many vegetarians.
Lifestyle Factors Play a Major Role: The health benefits often seen in vegetarian groups are also linked to other healthy behaviors, such as higher physical activity and lower rates of smoking.
A Balanced Approach Is Key: A well-planned, nutrient-dense diet is the most important factor for health, whether it is plant-based or includes meat.
Hybrid Diets Offer Benefits: Eating a plant-forward diet that includes lean meats, like the Mediterranean diet, also significantly reduces disease risk.

The Health Landscape: Deconstructing the Vegetarian and Omnivore Diets

The debate over whether a vegetarian or meat-inclusive diet is healthier is complex, as overall health depends on numerous factors beyond just meat consumption. A healthy diet, regardless of type, requires careful planning.

Chronic Disease Risks: Where the Evidence Points

Plant-based diets are linked to lower rates of heart disease, type 2 diabetes, and certain cancers. These diets are typically rich in fiber, vitamins C and E, and magnesium, and low in saturated fat and cholesterol. The EPIC study found vegetarians had a 19% lower risk of death from heart disease. A study also showed a vegetarian diet was twice as effective for weight reduction in type 2 diabetes patients compared to a low-calorie diet. It's worth noting that vegetarians often have other healthy habits like lower smoking and alcohol rates, and increased physical activity, which contribute to these benefits. However, a BMJ study noted a potential 20% higher stroke risk for vegetarians, particularly hemorrhagic strokes, possibly linked to low B12 or very low LDL cholesterol.

Nutrient Intake: Pros and Cons of Each Diet

Balancing nutrient intake is vital for any diet. Here's a look at common considerations:

Potential Nutrient Concerns in Vegetarian Diets:

Vitamin B12: Found mainly in animal products; fortified foods or supplements are needed for vegans.
Iron: Plant-based non-heme iron is less absorbable; combining with vitamin C helps.
Omega-3 Fatty Acids: EPA and DHA levels can be lower; ALA from plants isn't converted as efficiently.
Calcium and Vitamin D: Vegans may need fortified products or supplements.

Potential Nutrient Concerns in Meat-Inclusive Diets:

Saturated Fat and Cholesterol: High intake from red and processed meats increases heart disease risk.
Fiber: Often lower in omnivore diets compared to vegetarian ones.
Micronutrients: May be lower in protective antioxidants and phytonutrients if fruit and vegetable intake is low.

Comparison Table: Vegetarian vs. Meat-Inclusive Diet


Health Aspect	Vegetarian Diet	Meat-Inclusive Diet
Heart Disease Risk	Lower risk of ischemic heart disease.	Higher risk, especially with high red/processed meat consumption.
Type 2 Diabetes Risk	Lower risk, often linked to lower BMI.	Higher risk, linked to red and processed meat intake.
Certain Cancers	Lower overall cancer rates observed in some studies.	Higher risk for certain cancers (e.g., colorectal), linked to red meat.
BMI & Weight Control	Generally lower BMI and tendency to weigh less.	Higher average BMI and higher obesity rates.
Nutrient Balance	Requires careful planning to avoid deficiencies in B12, iron, and omega-3s.	Provides reliable sources of B12, iron, and omega-3s, but often lacks fiber.
Long-Term Health	Well-planned versions linked to longevity, but potential risks (e.g., stroke) exist.	Depends heavily on intake quality; less meat and more plants is key.

A Broader View of Health: It's Not Just About Food

Overall health isn't solely defined by whether meat is included in the diet. The quality of the diet and lifestyle choices are paramount. A vegetarian diet of processed junk food is not healthier than a balanced diet including lean protein, whole grains, fruits, and vegetables. Other healthy behaviors like exercise, not smoking, and moderate alcohol consumption also significantly influence health outcomes and are often seen in studies of vegetarian populations. Both dietary paths can support good health with careful planning and healthy habits. Consulting a registered dietitian can provide personalized guidance.

Conclusion: The Path to Optimal Health

Evidence suggests health benefits often associated with vegetarian diets, such as lower risk of heart disease, diabetes, and certain cancers, often stem from higher fiber and nutrient intake and reduced saturated fat. However, these benefits require a carefully planned diet; a poor vegetarian diet can lead to deficiencies. Those who eat meat can achieve similar health outcomes by reducing red and processed meat consumption and increasing plant-based foods. Ultimately, optimal health depends on a balanced, nutrient-dense diet and healthy lifestyle choices, not solely the inclusion or exclusion of meat.

Frequently Asked Questions

Yes, a varied vegetarian diet including legumes, nuts, seeds, and whole grains provides sufficient protein. Lacto-ovo vegetarians also consume eggs and dairy.

No, the healthfulness of any diet depends on the quality and balance of food choices, not just the exclusion of meat. A vegetarian diet of processed foods is not healthy.

Vegetarians and vegans should ensure adequate intake of Vitamin B12, iron, calcium, and omega-3 fatty acids, often found in animal products. These can be obtained through fortified foods, strategic food pairings, or supplements.

High consumption of red and processed meats is linked to increased risk of heart disease, type 2 diabetes, and certain cancers. Reducing meat and increasing plant foods can mitigate these risks.

Yes, a 'flexitarian' or 'plant-forward' diet with limited red meat and emphasis on plant foods can offer significant health benefits comparable to a strict vegetarian diet.

Some studies, including one in The BMJ, have reported a higher risk of hemorrhagic stroke in vegetarians. This is not fully understood but may relate to very low LDL cholesterol or B12 deficiencies, requiring further investigation.

A well-planned, balanced diet rich in whole foods is most important, regardless of whether it includes meat. Avoiding processed foods and maintaining an overall healthy lifestyle with exercise are also crucial.
