Vegan And Meat Diets: Can They Coexist?

Veganism has become increasingly popular in recent years, with many people adopting a vegan diet for ethical, environmental, or health reasons. A vegan diet is plant-based and excludes all animal products, including meat, dairy, and eggs. While veganism can provide several health benefits, such as lowering the risk of certain diseases and improving heart health, it is important to ensure that the diet is well-balanced and provides all the necessary nutrients. This is because a vegan diet can be restrictive and may lead to deficiencies in protein, calcium, vitamin B12, iron, and omega-3 fatty acids. Therefore, it is crucial for vegans to carefully plan their meals and include a variety of nutrient-rich plant-based foods to maintain a healthy and balanced diet.

The benefits of a vegan diet

A vegan diet can provide a range of health benefits, from supporting weight loss to reducing the risk of chronic diseases.

Firstly, vegan diets tend to be rich in nutrients and low in saturated fats. Research suggests that the diet can improve heart health, with a 2019 study linking a higher intake of plant-based foods and a lower intake of animal foods with a reduced risk of heart disease and death in adults. Animal products are the main dietary sources of saturated fats, which raise cholesterol levels and increase the risk of heart disease and stroke.

Secondly, a vegan diet may help with weight management. Many animal products are high in fat and calories, so replacing them with low-calorie plant-based foods can aid weight loss. A 2015 study reported that vegan diets were more effective for weight loss than omnivorous, semi-vegetarian, and pesco-vegetarian diets.

Thirdly, a vegan diet can lower the risk of type 2 diabetes. A 2019 review found that following a plant-based diet reduced the risk of type 2 diabetes, particularly when eating healthful plant-based foods such as fruits, vegetables, whole grains, nuts, and legumes.

Additionally, a vegan diet may offer some protection against certain cancers. The World Health Organization reports that at least one-third of all cancers can be prevented by factors within our control, including diet. A 2017 study found that vegans may have a 15% lower risk of developing cancer, and eating legumes regularly may reduce the risk of colorectal cancer by 9-18%.

Finally, a vegan diet can be beneficial for kidney health and managing blood sugar levels. A 2006 study reported that a vegan diet lowered blood sugar levels in people with diabetes more effectively than the recommended diet from the American Diabetes Association. A vegan diet may also reduce the risk of complications for people with type 2 diabetes, and several studies suggest it may help relieve pain caused by peripheral neuropathy, a common complication of diabetes.

In conclusion, a well-planned vegan diet can provide a range of health benefits, from improved heart health and weight management to a reduced risk of chronic diseases such as type 2 diabetes and certain cancers. However, it is important to ensure a balanced intake of nutrients, especially those that may be lacking in a vegan diet, such as vitamin B12, calcium, and iron.

The risks of a vegan diet

While a vegan diet has many health benefits, it also has some risks if not properly balanced. A vegan diet can be restrictive, and it is important to ensure that essential vitamins, minerals, and nutrients are obtained from a wide range of sources. Here are some of the potential health risks associated with a vegan diet:

Vitamin B12 Deficiency

Vitamin B12 is commonly found in red meat, eggs, fish, and milk, all of which are excluded in a vegan diet. This vitamin is critical for normal brain function, red blood cell production, enzyme formation, and cellular growth. A deficiency can lead to anemia, gastritis, stroke, Crohn's disease, and Celiac disease. It is important for vegans to include vitamin B12-fortified foods or supplements in their diet and monitor their vitamin levels.

Anemia

Anemia is a condition where the body fails to produce healthy red blood cells, disrupting oxygen distribution to organs. Vegans can develop anemia through iron deficiency or a lack of adequate vitamin B12 and folate, which are necessary for red blood cell production. Symptoms of anemia include irregular heartbeats, fatigue, and shortness of breath.

Leaky Gut Syndrome

Leaky gut syndrome or intestinal hyperpermeability occurs when tight openings in the intestinal barriers loosen, allowing toxic particles to enter the bloodstream. While the direct cause is unknown, illnesses like Crohn's disease and Celiac disease, which are associated with vegan diets, are linked to increased intestinal permeability. Legumes, a common source of protein in vegan diets, contain antinutrients that can contribute to leaky gut syndrome.

Mental Health Issues

Vegan diets have been associated with a higher prevalence of mental health problems, including depression and anxiety. This may be due to shortages in brain chemicals like serotonin, dopamine, and norepinephrine, which are influenced by nutrients in the diet such as omega-3 fatty acids, folates, vitamin B12, zinc, calcium, iodine, and iron. A vegan diet that does not adequately replace these nutrients can trigger symptoms of depression.

Hormonal Imbalance

Soy products, a common source of protein in vegan diets, contain phytoestrogens, which can act as endocrine disruptors and affect normal body functions. It is important for vegans to diversify their protein sources and not rely solely on soy products.

Pregnancy and Fetal Outcomes

Pregnant women on strict vegan diets are at risk of vitamin deficiencies, which can lead to poor fetal outcomes, including an increased risk of small-for-gestational-age infants and low birth weight. Vegan mothers may also have lower maternal fat reserves for breastfeeding, affecting their nutritional profile. It is crucial for pregnant and breastfeeding women to ensure they are meeting their nutritional needs through supplements or fortified foods.

The benefits of a meat diet

Meat is a rich source of several essential nutrients, and a great way to ensure you are getting the right amount of nutrients in your diet. Meat and poultry contain protein, which is important for growth and development, and other nutrients your body needs, such as iodine, iron, zinc, and vitamin B12.

Iodine helps your body produce thyroid hormones, while iron carries oxygen around your body. Zinc keeps your immune system strong, your skin healthy, and is important for growth, development, and reproductive health. Vitamin B12 is vital for your nervous system, and omega 3 supports heart and brain health.

Meat is a great source of these nutrients, and including meat in your diet can help ensure you are getting enough of them. For example, the Australian Dietary Guidelines recommend that you eat 1-3 servings of lean meat and poultry per day. During pregnancy, 3-4 servings are recommended.

Meat is also a good source of essential fatty acids and omega 3, which support heart health. Including meat in your diet can be a great way to ensure you are getting enough of these important nutrients, which have a range of health benefits.

However, it is important to note that the way you cook and store your meat matters. Lean, grilled meat is a healthier option than fried meat with added oils. It is also important to stick to the recommended serving size and not to eat too much meat, as it can be high in salt and saturated fat, especially processed meat.

Overall, a meat diet can provide several benefits due to the high nutrient content of meat. However, it should be complemented with a balanced diet of fruits, vegetables, and whole grains to ensure optimal health.

The risks of a meat diet

There are several health risks associated with meat consumption, especially in the long term. The risks are more pronounced with red meat and processed meat, such as bacon, sausages, and salami. Here are some of the potential dangers:

Increased Risk of Mortality and Disease

Regular consumption of red meat, especially in high amounts, has been linked to an increased risk of total mortality, including from cancer and cardiovascular disease. Substituting meat with other protein sources like fish, poultry, legumes, and whole grains can help lower this risk.

Cancer

Studies have found a correlation between meat consumption and an increased risk of certain types of cancer, including colorectal cancer and breast cancer. The World Health Organization has classified processed meat as carcinogenic, placing it in the same category of cancer risk as asbestos and cigarette smoking.

Cardiovascular Disease

High intakes of red and processed meat have been associated with a higher risk of cardiovascular disease. Meat consumption can lead to harmful cholesterol levels, which can cause clogged arteries and contribute to heart disease.

Type 2 Diabetes

Research suggests that even modest consumption of red or processed meat can significantly increase the risk of type 2 diabetes. This is because meat is considered one of the most well-established dietary risk factors for this illness.

Obesity

A diet high in meat can contribute to obesity. This is because meat protein is digested more slowly than fats and carbohydrates, resulting in a surplus of energy that gets converted and stored as fat in the body.

Alzheimer's Disease

A Western diet that is heavy in animal proteins has been linked to a higher risk of developing Alzheimer's disease. On the other hand, plant-based diets rich in fruits, vegetables, and nuts have been associated with better cognitive health.

Shorter Lifespan

Long-term vegetarians tend to have a longer life expectancy than those who regularly consume meat. One study found that those on a vegetarian diet for more than 17 years enjoyed an increase in life expectancy of 3.6 years.

How to balance a vegan and meat diet

A vegan and meat diet can be balanced, but it requires careful planning to ensure you are getting all the right nutrients. Here are some tips to help you balance a vegan and meat diet:

Focus on Whole Foods

Choose whole food plant ingredients instead of processed options whenever possible. Processed vegan and vegetarian products often contain extra salt, added sugars, and calories. By focusing on whole foods, you will get more nutrients, including vitamins, minerals, and antioxidants. Some examples of whole foods to include in your diet are fruits, vegetables, nuts, seeds, and legumes.

Get Enough Protein

Protein is essential for maintaining healthy muscles, skin, bones, and organs. Include high-protein foods in your diet, such as eggs, dairy products like yogurt and cottage cheese, legumes, seeds, and nuts. If you have certain health conditions or dietary restrictions, consult a healthcare professional for personalized advice.

Monitor Your Vitamin and Mineral Intake

Pay attention to your vitamin and mineral intake, especially vitamin B12, calcium, iron, and zinc. Vitamin B12 is typically found in animal products, so vegans may need to include fortified foods or supplements in their diet to meet their daily requirements. Calcium can be obtained from dairy products for vegetarians, while vegans can opt for calcium-rich vegetables like collard greens, kale, and soy products, as well as calcium-fortified plant-based milk and orange juice. Iron and zinc can be found in plant-based sources, but their absorption is enhanced when combined with vitamin C-rich foods.

Choose Healthy Carbohydrates

Opt for whole grains such as brown rice, quinoa, and oatmeal instead of refined carbohydrates like white bread and white rice. Whole grains provide more fibre, B vitamins, and iron, promoting better nutrition and satiety.

Be Mindful of Added Sugars and Fats

Read nutrition labels and be mindful of the saturated fat and added sugars content in ready-made vegan and vegetarian products. High intake of saturated fat and added sugars can lead to health issues like weight gain, heart disease, and diabetes. Choose unsaturated fats like olive, vegetable, grapeseed, or sunflower oil when possible.

Include Omega-3 Sources

Omega-3 fatty acids are essential for maintaining heart, eye, brain, and skin health. While they are commonly found in fish, vegans can obtain omega-3s from plant-based sources such as walnuts, beans, chia seeds, flaxseeds, and green leafy vegetables.

Remember to consult a healthcare professional or a registered dietitian if you have any specific health concerns or need personalized advice on balancing your vegan and meat diet.
