Diabetes is one of the most significant and challenging health issues worldwide. However, we can look at a mix of medical interventions and lifestyle changes to cure diabetes. Therefore, it is necessary to follow specific diet plans to control it.

Some studies recommend a vegan diet or plant-based foods as the best choices to lower the risk of diabetes. Contrary to popular belief, a vegan diet provides a variety of nutrients in sufficient amounts to maintain good health.

Diabetes and Vegan Diet

If you have diabetes, it is essential to introduce dietary modifications to maintain a healthy lifestyle. Also, some foods cause a rise in blood glucose levels.

Experts say a vegan diet or plant-based food is the best choice in this case. ‘Choose Plant based foods more often, as it’s kinder to the body and the environment… this makes it a double win for you and the Earth‘- Parul Dube (Nutritionist with HealthifyMe)

Obesity has direct linkages with Type 2 diabetes. Hence, consuming foods with a low glycaemic index can reduce weight and insulin resistance.

Other benefits of a vegan diet include lowering cholesterol, reducing saturated fat, and reducing the risk of heart disease. All of these are good for people with diabetes.

It is preferable to finish dinner between 7 and 8 p.m. People with high sugar levels should avoid eating fruits at night. Dinner should be light, and you must follow it with a post-dinner walk. You can have a bowl of soup and some salad with tofu or besan chilla for a satisfying but easy-to-digest dinner. In addition, you can have clear soups with grilled paneer/chickpea or red bean salad.

Foods to Avoid in a Vegan Diet Plan

There are certain foods for diabetic patients to avoid in their regular diet plan. Here is the list of those food items and reasons to avoid them.

White Bread

White bread is a favourite food in general. But unfortunately, it is high in sugar and carbohydrates. These increase the sugar levels in your body abruptly. So refrain from having it.

Sugar Laden Nut Milk

Store-bought nut milk may contain sugar and can be from peeled nuts. Therefore, the fibre content reduces, and antioxidants get removed. As a result, it may spike sugar levels.

White Rice

We usually love eating white rice. White rice is polished and has a higher GI value. However, it is high in carbohydrates and fibre. These can also cause sugar levels to rise. People with sugar should opt for unpolished brown or red rice instead of white rice.


We all love our share of French fries. However, potatoes are high in starch and can spike blood sugar levels. So it is better to avoid them.

Fruit Juices 

Research shows that an average of 18% of people who consume large amounts of fruit juices develop diabetes. So people with sugar should avoid them.


Raisins are high in calcium, magnesium, potassium, fructose, glucose and antioxidants. These can also cause sugar levels to rise.

French Fries

French fries are a favourite food of many when going to theatres and restaurants. But unfortunately, the ingredients used in them are made with potatoes. Hence, it is not suitable for people with diabetes.

Soft Energy Drinks

Those with sugar should also avoid soft drinks with added sugar. These include preservatives and additives that increase  and cause sugar levels to rise.

Artificial Sweeteners

Many sugar patients consume artificial sweeteners. However, some natural sweeteners, like stevia, may suit your health better. Moreover, do consult with your family doctor before you make a swap!

Additional Tips to Control Diabetes

Multiple factors impact blood glucose levels that lead to hyperglycaemia. So there are numerous options practices and a vegan diet plan to look over for managing diabetes. You can expect significant improvements if you follow some tips and a vegan diet plan.

Regular Exercise

Regular exercise in your daily routine can help you maintain a constant weight and increase insulin sensitivity. While exercising, your body utilises the blood sugar for energy and muscle contraction, thus decreasing the levels and maintaining blood glucose within the range.

Research suggests that getting mild intensity walks and simple resistance activities lower blood glucose levels. Simple exercises include walking, cycling, running, brisk walking, squats, dancing, and weightlifting helps in regulating glucose levels in the body.

Drink More Water

Drinking more water is simple, easy and yet best practice to minimise blood sugar levels. Excess moisture in the body helps the kidneys flush out additional blood glucose and other toxins through urine. In addition, water and other zero-calorie liquids without artificial sweeteners help you maintain blood glucose levels.

Maintaining Moderate Weight

Moderate weight management aids in reducing blood glucose levels and thus lowers the chances of developing type 2 diabetes.

Reducing Stress 

If you have more stress, then you risk developing type 2 diabetes. When stressed, the body releases glucagon and cortisol hormones that increase blood glucose levels. So try to reduce the stress to lead a healthy life.

Meditation and Yoga

As discussed earlier, stress can affect blood glucose levels. So to reduce it, meditation and yoga are the best practices. They can also rectify insulin secretion problems, thus helping regulate glucose levels in the blood.

Keep Checking Your Blood Glucose Levels 

Constantly checking your blood glucose levels will help you understand how your body responds to your diet plans, exercises or medications. Over time, using this strategy you can make the necessary modifications to  better maintain your health. Regulate and maintain them within the limit.

Enough Sleep

Having good quality sleep is essential for your health. Conversely, poor sleeping habits and lack of rest affect insulin sensitivity and lead to stress. In addition, it increases the production of cortisol hormone in your blood. As a result, it increases the chances of getting type 2 diabetes.

Have Healthy Snacks Frequently 

Eating snacks between meals reduces the chances of type 2 diabetes. Also, experts suggest eating low glycaemic index foods multiple times in a smaller quantity throughout the day. It decreases glycated haemoglobin readings and improves blood glucose levels.


Food intake, mainly a vegan diet, plays a significant role to control your diabetes. But all vegan foods are not suitable for diabetes. Those with low carbohydrates, low GI and rich in proteins and minerals are the best choices to include in the regular diet on a plan. In addition, plant-based foods are good for diabetes. However, those on a vegan diet may still be at risk of certain nutrient deficiencies like Vit B12, B6, B1, Calcium, Iodine, and omega-3 fatty acids. So make sure to use supplements.

You should also include nutrient-dense vegan foods like fortified yeast, chickpeas, potatoes, bananas, dark chocolate, soya milk, almond milk, flax seeds, chia seeds and kidney beans. Please remember one size does not fit all. It is prudent to take advice from a certified nutritionist when designing a modified menu plan.
