Vegan Diet Benefits: A Healthier Body

A vegan diet can have a wide range of health benefits for the body. Research suggests that a plant-based diet can improve heart health, lower the risk of chronic diseases, and support weight loss.

Vegan diets are typically rich in nutrients and low in saturated fats. They are associated with a reduced risk of heart disease, type 2 diabetes, and certain types of cancer. Additionally, vegans tend to have lower body mass indexes (BMIs) than non-vegans, making it an effective approach for weight management.

However, it is important to note that a vegan diet may require careful planning to ensure adequate intake of certain nutrients like iron, calcium, vitamin B12, vitamin D, and omega-3 fatty acids, which are typically obtained from animal products.

Overall, a well-planned vegan diet can be a nutritious and healthy choice, offering benefits such as weight management and reduced risk of chronic diseases.

Weight loss

A vegan diet can be an effective way to lose weight. Research has shown that people who follow a vegan diet tend to have a lower body mass index (BMI). This could be because plant-based foods are generally high in fibre and low in fat, leading to a reduced calorie intake and increased feelings of fullness. A study published in the *European Journal of Clinical Nutrition* found that participants who followed a vegan diet lost an average of 13 pounds over 16 weeks, without receiving nutritional guidance or restricting their calorie intake.

However, it is important to note that not all vegan foods are healthy. Vegan junk food, such as cakes, candies, and fried foods, can also lead to weight gain. To maximise weight loss on a vegan diet, it is important to focus on whole, unprocessed plant-based foods such as fruits, vegetables, whole grains, legumes, nuts, and seeds. These foods are rich in fibre and essential nutrients, which can support weight loss and overall health.

• Focus on whole foods: Prioritise eating whole, unprocessed plant-based foods. These foods are rich in fibre, vitamins, and minerals, which can support weight loss and overall health.
• Practice portion control: Even when consuming plant-based foods, overeating can hinder weight loss. Pay attention to hunger and fullness cues and practice mindful eating.
• Optimise protein intake: Include various plant-based protein sources such as legumes, tofu, tempeh, and plant-based protein powders. Protein helps with satiety and preserves lean muscle mass during weight loss.
• Understand the role of fats: Incorporate healthy fats, such as avocados, nuts, seeds, and plant-based oils, in moderation. These fats provide satiety and contribute to overall meal satisfaction.
• Balance macronutrients: Aim for a balanced distribution of complex carbohydrates, proteins, and healthy fats. This supports sustained energy levels, promotes fullness, and aids in weight management.
• Consider snacks: Include healthy snacks such as fresh fruits, raw vegetables, nuts, or homemade plant-based options. Choose nutrient-dense snacks and be mindful of portion sizes.
• Avoid ultra-processed plant-based foods: Not all vegan products are healthy. Many packaged cookies, chips, and meat substitutes are vegan but highly processed and high in calories.
• Prioritise physical activity: Combine your vegan diet with regular physical activity, including strength and resistance activities, to maintain lean muscle mass while losing weight.

By following these tips and focusing on a balanced, whole-food vegan diet, individuals can effectively lose weight and improve their overall health.

Lower risk of type 2 diabetes

A vegan diet can help lower the risk of type 2 diabetes. Research has shown that a plant-based diet may help restore the function of beta cells, which produce insulin and keep blood sugar stable. A 2019 study found that a plant-based diet can completely reverse the decline of beta-cell function, improving its ability to produce insulin and stabilise blood sugar.

Beta-cell failure is indicated by a loss of sensitivity to glucose. In a study, scientists found that beta-cell glucose sensitivity increased by 65.5% in the vegan group, resulting in a notable increase in insulin secretion compared to the control group. This suggests that a diet high in plants and low in animal products may produce these positive results by reducing oxidative stress and inflammation.

Vegan diets are also associated with lower body mass indexes (BMIs) and lower body fat percentages. This is beneficial in reducing the risk of type 2 diabetes, as insulin resistance is often high in overweight people, putting a strain on beta cells to produce insulin.

A vegan diet can also help manage existing cases of type 2 diabetes. A 2006 study reported that a vegan diet lowers blood sugar levels in people with diabetes more than the recommended diet from the American Diabetes Association (ADA). In a 2009 study, 43% of participants following a vegan diet were able to reduce their dosage of blood sugar-lowering medication, compared to only 26% of participants who followed an ADA-recommended diet.

In general, a vegan diet is thought to lower the risk of complications for people with type 2 diabetes. People with diabetes who substitute plant protein for meat may also reduce their risk of poor kidney function.

Lower risk of certain cancers

A vegan diet may help lower the risk of certain cancers. Research suggests that a vegan diet may reduce a person's risk of cancer by 15%. This is because plant-based foods are high in fibre, vitamins, and phytochemicals—biologically active compounds in plants that protect against cancers. Phytochemicals also decrease inflammation and interrupt processes in the body that encourage cancer production.

Plant-based diets are full of fruits, vegetables, and legumes, with little to no meat or other animal products. Vegans generally eat more legumes, fruits, and vegetables than non-vegans. This may explain why a 2017 study found that vegans may benefit from a 15% lower risk of developing cancer.

Eating legumes regularly may reduce the risk of colorectal cancer by 9–18%. According to the National Cancer Institute, eating more plant-based foods reduces the risk of several types of cancer, including stomach, lung, mouth, throat, colon, prostate, and pancreatic cancers.

Vegan diets also tend to contain more soy products, which may offer some protection against breast cancer. Additionally, avoiding meat and dairy may help reduce the risk of prostate, breast, stomach, and colorectal cancers. Red meat, smoked meat, or processed meats cooked at high temperatures are thought to promote certain types of cancers.

However, it is important to note that these studies are observational and do not pinpoint the exact reason vegans have a lower risk of cancer.

Improved heart health

A vegan diet can improve heart health in several ways. Firstly, it can help to reduce the risk of heart disease and death in adults. This is because a vegan diet is typically rich in plant-based foods, which are high in fibre, and low in animal-based foods, which are the main dietary sources of saturated fats. According to the American Heart Association (AHA), eating foods containing saturated fats raises cholesterol levels, increasing the risk of heart disease and stroke.

Plant-based diets are also associated with a lower body mass index (BMI) and a reduced risk of obesity, which is a major risk factor for heart disease. This is because people on a vegan diet often consume fewer calories than those on a standard Western diet, due to the higher proportion of whole foods in their diet. A moderate calorie intake can lead to a lower BMI and a reduced risk of obesity.

In addition, a vegan diet can help to lower cholesterol levels, particularly "bad" LDL cholesterol, which is another risk factor for heart disease. This is because plant-based diets tend to be rich in nuts, plant proteins, viscous soluble fibre, plant sterols, and monounsaturated fats—all of which are beneficial for lowering cholesterol.

Furthermore, a vegan diet can help to reduce high blood pressure, which is a risk factor for heart disease. Observational studies have reported that vegans may benefit from up to a 75% lower risk of developing high blood pressure, due to the inclusion of more fruits, vegetables, legumes, and fibre in their diet.

Overall, a well-balanced vegan diet can significantly reduce the risk factors that contribute to heart disease and improve overall heart health.

Reduced pain from arthritis

A vegan diet can help reduce pain from arthritis, particularly rheumatoid arthritis, an autoimmune disease that causes joint pain, swelling, and permanent joint damage.

A 2015 study found that a vegan diet significantly reduced C-reactive protein (CRP), a marker for acute and chronic inflammation. A 2017 meta-analysis of 17 studies also found that a vegan diet was associated with lower CRP levels.

A study published in the American Journal of Lifestyle Medicine found that a low-fat vegan diet improved joint pain in patients with rheumatoid arthritis. The study included 44 adults with rheumatoid arthritis who were put on a vegan diet for 4 weeks, followed by the elimination of additional inflammatory foods for 3 weeks. The vegan phase of the study resulted in a greater reduction in joint pain and swelling compared to the placebo phase. Researchers suggested that the reduction in swelling and inflammation recorded among participants showed that dietary changes were associated with symptomatic improvements.

A vegan diet may also help reduce arthritis pain by eliminating certain trigger foods that promote inflammation. These include red and processed meat, processed foods, refined carbs, saturated fat, alcohol, sugary foods and drinks, and gluten-containing carbohydrates for individuals with non-celiac gluten intolerance.

In addition to reducing pain and swelling, a vegan diet has also been found to lead to weight loss and improved cholesterol levels in individuals with rheumatoid arthritis.

However, it is important to note that dietary interventions may not be sufficient on their own to manage arthritis symptoms, and alternative traditional medical treatments may also be necessary.
