The Numerous Benefits of Going Plant-Based
In recent years, there has been a growing interest in adopting a plant-based diet. With the rise of documentaries like "Forks Over Knives" and "What the Health," more and more people are becoming aware of the potential health benefits of minimizing or eliminating animal products and adopting a diet focused on fruits, vegetables, whole grains, legumes, nuts and seeds. But what exactly are the benefits of going plant-based? Let's take a closer look at some of the key ways this diet can impact your health.
1. Lower Risk of Heart Disease
One of the best known benefits of a plant-based diet is a reduced risk of heart disease. According to a major 2021 study published in the Journal of the American Heart Association, middle-aged adults who ate the most plant-based foods had a 16% lower risk of having a cardiovascular condition, like heart disease or stroke, compared to those who ate the least amount of these foods. Plant-based diets have been shown to help lower cholesterol levels, blood pressure and inflammation, all key factors in heart health.
2. Reduced Risk of Type 2 Diabetes
Several studies have found that following a predominantly plant-based diet can reduce the risk of developing type 2 diabetes. A large review published in Nutrients looked at ten studies with over 150,000 participants. It found that both semi-vegetarian and vegan diets were associated with a 30% lower risk of type 2 diabetes compared to non-vegetarian diets. Plant-based diets are typically high in fiber and nutrients that help regulate blood sugar levels and lower insulin resistance.
3. Lower Blood Pressure
High blood pressure is one of the major risk factors for heart disease. A plant-based diet full of fruits, vegetables, whole grains, beans, lentils, nuts and seeds has consistently been shown to lower blood pressure levels. One review in the Journal of Geriatric Cardiology looked at 27 randomized controlled trials. It found that plant-based diets reduced systolic blood pressure by 4.8 mmHg and diastolic blood pressure by 3.2 mmHg on average.
4. Improved Gut Health
Your gastrointestinal system contains trillions of bacteria, fungi and other microorganisms that impact your overall health. Studies indicate that plant-based diets high in fiber and phytonutrients help support the growth of beneficial gut bacteria. They also minimize harmful bacteria and inflammation in the gut microbiome. This optimizes digestion and gut functioning to lower the risk of gastrointestinal disorders.
5. Healthy Weight Management
Obesity continues to be a major public health challenge worldwide. However, research shows that plant-based diets can be effective for long-term weight loss and maintenance. This is likely due to their high fiber and water content, which helps promote satiety and reduce total calorie intake. One study followed over 130,000 people in France for 5 years. It found that those who increased their intake of plant foods lost more weight compared to those who decreased plant food intake.
Additional Benefits of a Plant-Based Lifestyle
Beyond these major health benefits, there are numerous other advantages associated with plant-based diets, including:
6. Lower Cancer Risk
Eating more plant foods and less processed meat has been linked to a lower incidence of cancer. The World Cancer Research Fund International reports that vegetarian diets could prevent over 11% of cancer cases in developed countries like the US, UK and Australia.
7. Increased Longevity
Several studies have found that those who adhere to plant-based diets, like vegans and vegetarians, tend to live longer than meat-eaters. According to one study in JAMA Internal Medicine, vegetarians had a 12% lower risk of death over a 5.5 year study period compared to non-vegetarians.
8. Lower BMI
Plant-based diets are associated with lower BMIs (body mass index). BMI is a measure of body fat based on height and weight. A systematic review and meta-analysis published in the Journal of General Internal Medicine looked at 156,317 people. It found that vegetarians and vegans had significantly lower BMIs compared to meat-eaters.
9. Clearer Skin
Some research indicates that certain plant foods like fruits, vegetables, nuts and seeds, and even dark chocolate, may support healthy, clear skin. Meanwhile, studies link dairy intake to increased acne. More investigation is still needed, but anecdotal evidence suggests plant-based dieters often report improvements in skin health and appearance.
10. Ethical Reasons
In addition to health, many people choose to go plant-based due to environmental, ethical or religious concerns. For example, reducing meat consumption lowers your carbon footprint and promotes more sustainable farming practices. These are compelling reasons for some to adopt a predominantly plant-based lifestyle.
Achieving an Optimal Plant-Based Diet
While any increase in plant foods is beneficial, experts recommend focusing on the principles of a whole food, nutrient-dense diet for optimal health:
Emphasize Vegetables, Fruits, Legumes, Nuts and Seeds
Make plant foods like leafy greens, vegetables, fresh fruits, beans and lentils the foundation of your meals. Get protein from nuts, seeds and soy foods like tofu and tempeh.
Choose Whole Grains
Opt for minimally processed whole grains like oats, brown rice, farro, buckwheat and quinoa whenever possible over refined grains.
Limit Processed Foods
Highly processed vegan meat alternatives and snacks should be minimized. Always check the ingredient lists.
Don't Forget Healthy Fats
Include plant-based sources of omega-3s, like walnuts, flax and chia seeds. Use extra virgin olive oil and avocados for healthy fats.
Take B12
Vegans should supplement with vitamin B12 or consume fortified foods to avoid deficiency.
The Takeaway
Transitioning to a plant-based diet is one of the most impactful lifestyle choices you can make to dramatically improve overall health and longevity. By focusing on eating more vegetables, fruits, legumes, whole grains and healthy plant-based fats, you can experience benefits ranging from a reduced risk of major diseases to better weight management and more.
