A low-fat vegan diet rich in grains, beans, fruits, and vegetables can lower insulin needs while improving blood sugar control, and enhance insulin sensitivity in diabetes, according to a groundbreaking study. The research also highlights benefits such as better weight management, improved cholesterol, and healthier kidney function.
Diabetes results from reduced insulin production due to an autoimmune reaction. Dietary fat can worsen insulin resistance while keeping blood sugar high and increasing the risk of complications. Read more to know how veganism makes managing diabetes easier.
Nutritional Benefits of Veganism
The vegan diet generally excludes all animal-based foods, including meat and dairy products. Although it can be a nutritious way of eating, following a vegan diet as a diabetic person requires an extra layer of planning.
Fortunately, many plant-based foods, such as grains and beans, contain a mixture of proteins, carbohydrates, and fats, so they can easily perform double or triple nutritional duty in meal planning.
Additionally, fibre is an indigestible carbohydrate generally found in most plant-based foods. It helps make these foods more filling and may even reduce blood sugar levels.
Vegan Diet and Type 2 Diabetes Management
Some of the research-backed and potential benefits of a vegan diet for type 2 diabetes mainly include:
Vegan diets have been shown to help manage blood sugar levels in individuals with Type 2 diabetes. They may also reduce the need for diabetes medication and improve insulin sensitivity by approximately 10%.
A vegan diet also helps people manage weight with type 2 diabetes. The diet usually contains fewer calories and less fat. Losing weight also improves insulin sensitivity.
Veganism and Cardiovascular Health
Compared to non-vegetarian diets, vegetarian diets are linked to a lower risk of cardiovascular disease and death. Vegan diets, in particular, show improvement in heart health, including:
Lower blood pressure
Balanced cholesterol levels
Reduced triglyceride levels
Ideal BMI (Body Mass Index)
Lower inflammation markers
Long-Term Health Outcomes
Here are some important factors to keep in mind when following a vegan diet for diabetes to reduce health-related risks:
Highly processed vegan foods can be low in protein and fibre, and high in sugar and additives. This mainly includes sugary drinks like fruit juices and sodas.
Excessive processed food can increase the risk of diabetes, certain cancers, and high blood pressure. While a person doesn't need to avoid them entirely, it is best to limit them, especially in case a diabetic patient has trouble managing blood sugar levels.
A person should avoid snacks or meals that are mostly carbs with little fat or protein.
The use of protein in vegan diets helps reduce the impact of carbs on blood sugar while making a person feel full for a longer time.
Healthy fats such as olive oil can also improve heart health and even help absorb nutrients.
Challenges and Considerations
People with diabetes may face certain challenges when following a vegan diet, but these can be effectively managed with proper planning.
Diabetic patients on vegan diets may be at higher risk of nutrient deficiencies, especially in vitamin B6, B12, calcium, iron, niacin, zinc, iodine, fats, and omega 3. These are mainly found in animal products. However, these nutrients can be obtained through plant-based foods or supplements rich in them.
People with diabetes on a vegan diet may find it difficult to consume enough protein and the essential amino acids needed for good health. However, this can also be managed with proper diet planning.
A vegan diet for people with diabetes can lead to consuming too many carbs that may affect blood sugar levels. Plant-based foods are generally high in carbs. So, it is important to moderate the intake and consult healthcare providers for the right amount.
Here are some essential tips if a person wants to succeed at a vegan diet for diabetes to help them stay on track and stay strong:
A person should plan meals and keep healthy snacks ready. They can also check restaurant menus in advance when dining out.
Non-starchy vegetables are low in carbohydrates but rich in nutrients and fibre. They have a minimal impact on blood sugar while helping to keep a person full and satisfied.
Vegan diets can be low in certain nutrients, so supplementation is usually necessary. A person can consult their doctor to choose the right supplement according to their nutrient deficiencies.
A person should also make sure that every snack and meal contains a healthy balance of protein, fats, and carbs, along with some non-starchy vegetables for better nutrition.
Taking a variety of plant-based protein sources in a diet ensures that a person gets all the amino acids in the amount that is required for optimal health.
A person should also check the blood sugar regularly to be aware of the blood sugar patterns. It is required to consult a healthcare provider in case of any concern.
Conclusion
A vegan diet is known for health benefits such as blood sugar control, better cholesterol, and lower risks of diabetes, heart disease, and obesity. However, a person must avoid processed foods, limit carbs, and also ensure to get enough nutrients and protein for better results.
While a vegan diet is a healthy option for managing diabetes, people should even explore its long-term effects and understand the latest insights for improved health outcomes.
