Vegan Diet Benefits For Diabetics: How Long To Commit?

A vegan diet can be a healthy choice for people with diabetes, but careful planning is required to ensure nutritional needs are met.

The vegan diet is completely free of meat, dairy, and animal-based products. It can be a nutritious way of eating, but it requires careful planning to make sure all nutritional needs are met. This is especially true for people with diabetes, who need to keep their carb intake consistent throughout the day.

A vegan diet for diabetes should include a healthy balance of plant-based protein, carbs, and fat. It should also include non-starchy vegetables, which are very low in carbs but full of fibre and nutrients.

There is some evidence that a vegan diet can help improve blood sugar levels and insulin sensitivity, as well as aid weight loss among people with overweight or obesity. However, it's important to avoid excessive carbs and highly processed foods, and to ensure adequate protein and nutrient intake.

Some tips for succeeding on a vegan diet for diabetes include planning ahead, eating plenty of non-starchy vegetables, balancing each meal and snack, and supplementing wisely.

A vegan diet can help with weight management, which is key to improving glycemic control

Meals and snacks should be balanced with carbs, protein, and healthy fats, as including non-carb foods can reduce the impact of carbs on blood sugar. Many plant-based foods, such as beans and grains, contain a mix of carbs, protein, and fat, so they can be used in various ways in meal planning.

Fiber, a type of indigestible carb found in most plant-based foods, helps make meals more filling and may reduce their blood sugar impact. It is important to eat a variety of plant-based protein sources to get all the essential amino acids needed for optimal health.

Vegan diets tend to be lower in fat and calories than omnivorous diets, which may make weight loss easier. Research shows that vegan diets may improve blood sugar levels and insulin sensitivity and aid weight loss among people who are overweight.

However, it is possible to overeat carbs on a vegan diet, which can affect blood sugar levels. Plant foods tend to be higher in carbs than animal foods, so it is important to moderate intake to maintain healthy blood sugar levels.

In addition, vegan diets can be low in certain nutrients, so supplementation is often necessary. It is also important to get enough protein, as protein is necessary for creating new bodily tissues, and amino acids play a variety of roles in health.

How the vegan diet for diabetes works

For people with diabetes, following a vegan diet will require an extra layer of planning. In general, people with diabetes need to keep their carb intake consistent throughout the day, as carbs affect blood sugar levels more significantly than protein and fat.

Meals and snacks should also be balanced with carbs, protein, and healthy fats since including non-carb foods in your meal can help reduce the carbs' effects on your blood sugar.

Blood sugar management

There is some evidence that a vegan diet can help improve blood sugar levels and insulin sensitivity, as well as aid weight loss among people with overweight or obesity. One 12-week study in 93 Korean people with diabetes found that following a vegan diet resulted in slightly improved blood sugar management than following a conventional diet.

Another review noted that diets that emphasized plant-based food intake, including vegan, vegetarian, Mediterranean, and the Dietary Approaches to Stop Hypertension (DASH) diet, tended to reduce hemoglobin A1C by 0.8%. Your hemoglobin A1C level is a measure of blood sugar management across the previous 3 months, and it’s a good indicator of long-term blood sugar management.

Insulin sensitivity

Because type 2 diabetes is characterized by insulin resistance (when cells stop responding to the hormone insulin), increasing insulin sensitivity can help reduce blood sugar and insulin levels, as well as the need for insulin injections among some people with diabetes.

One way researchers measure insulin resistance is called the homeostasis model assessment index for insulin resistance (HOMA-IR). In one 16-week study among 244 overweight adults, researchers noted that those who switched to a low-fat vegan diet had greater decreases in their HOMA-IR than those eating their normal diet, meaning they became more sensitive to insulin.

A similar study in 75 overweight adults noted that a vegan diet significantly reduced HOMA-IR, along with body weight and fat mass, compared with a control diet. Researchers theorize that animal proteins may contribute more strongly to the development of insulin resistance than plant proteins. However, overall diet quality is likely a greater contributor than animal protein consumption or avoidance.

Weight management

Finally, a vegan diet may be beneficial for people with type 2 diabetes by helping them manage their weight. Losing weight can help improve insulin sensitivity, and vegan diets tend to be lower in fat and calories than omnivorous diets, which may make it easier to lose weight. Alongside the improvements in insulin resistance observed in the studies above, researchers also noted that the vegan diet resulted in more body fat and weight loss.

Downsides of a vegan diet

There are some potential downsides to the vegan diet in general — and particularly for people with diabetes. Fortunately, these downsides are avoidable with careful planning.

Nutrient deficiencies

People who eat vegan diets are at a greater risk of developing certain nutrient deficiencies than other people, particularly deficiencies in vitamin B12, vitamin B6, niacin, iron, calcium, omega-3 fats, iodine, and zinc, which are all more prevalent in animal foods. However, you can get all of these nutrients by either supplementing or purposefully including plant-based foods that are good sources of these nutrients in your diet.

Protein and amino acids

It can also be difficult for people on vegan diets to get enough protein and the right variety of amino acids (the building blocks of protein) to maintain optimal health. Protein is necessary for creating new bodily tissues, and amino acids play a variety of roles in your health.

Although again, this problem can be solved with a little bit of planning. Great vegan sources of protein include soy, legumes, nuts, seeds, grains, and protein powders. In addition, most vegan protein sources are considered incomplete — meaning that, unlike animal protein sources, they don’t contain all of the essential amino acids in the right amounts. To make sure you’re getting all of the amino acids you need, mix up your protein sources and get your protein from various plant-based sources each day.

Excessive carbs

One final pitfall of the vegan diet that can affect people with diabetes, in particular, is that it’s easy to overdo it on the carbs, which can affect your blood sugar levels. Plant foods tend to be higher in carbs than animal foods, so a vegan diet will naturally be higher in carbs than an omnivorous diet. If you eat many highly processed vegan foods, it can be easy to eat carbs in excess of what your healthcare team recommends. While carbs as a whole aren’t unhealthy and can certainly be part of a healthy diet for diabetes, it’s important to moderate your intake to maintain healthy blood sugar levels.

A vegan diet can help reduce the risk of developing type 2 diabetes

A vegan diet is a way of eating that excludes all animal products, including meat, dairy, eggs, and honey. It is often chosen for ethical reasons, such as concern for animal welfare or the environment. A vegan diet can also offer some health benefits, such as lower levels of type 2 diabetes, reduced hypertension, lower cholesterol levels, and reduced cancer rates.

A vegan diet can be a healthy and balanced way to manage type 2 diabetes. It tends to be lower in saturated fat and higher in fibre, fruit, and vegetables, which are all beneficial for people with diabetes. Additionally, a vegan diet can help with weight management, which is crucial for improving insulin sensitivity.

There are a few potential downsides to a vegan diet that people with diabetes should be aware of. Firstly, it can be more challenging to get enough protein and essential amino acids on a vegan diet. It is important to include a variety of plant-based protein sources, such as soy, legumes, nuts, seeds, and grains, to ensure adequate protein intake.

Another potential downside is the risk of nutrient deficiencies. People following a vegan diet may be more likely to develop deficiencies in vitamin B12, vitamin B6, iron, calcium, omega-3 fats, iodine, and zinc. However, these deficiencies can be avoided by including plant-based sources of these nutrients in the diet or taking supplements.

Finally, it can be easy to overdo it on carbs when following a vegan diet, as plant-based foods tend to be higher in carbs than animal-based foods. Excessive carb intake can affect blood sugar levels, so it is important to monitor carb intake and choose low-GI options.

Pitfalls to avoid on a vegan diet with diabetes

Excessive processed food intake

Highly processed foods — including vegan ones — are often loaded with sugar and additives and poor in fiber and protein. Although you don’t have to avoid these foods totally, you should limit them, especially if you have trouble managing your blood sugar levels.

Low fat and low protein meals

You should try to avoid meals or snacks that primarily comprise carbs and contain little protein or fat. Protein can help reduce carbs’ effect on your blood sugar levels and may help enhance sensations of fullness. In addition, fat sources like olive oil may provide some additional health benefits like improving heart health and helping boost the absorption of certain nutrients.

A vegan diet can help reduce the risk of other health complications associated with diabetes

Vegan diets tend to be lower in saturated fat, higher in fibre, fruit and vegetables, and other protective substances like phytochemicals and antioxidants. This means they fit well with the current dietary guidelines for people with diabetes.

Vegan diets have been shown to help in the treatment of many chronic diseases and are often associated with lower levels of type 2 diabetes, less hypertension, lower cholesterol levels, and reduced cancer rates.

Some studies also show that vegans are less likely to be overweight and tend to have a lower percentage of body fat, which in turn will reduce the risk of many other diseases.

However, it's important to note that not all vegan diets are healthy. Ingredients such as salt, sugar, and fat can still be added, making them less healthy. It's also important to ensure that a vegan diet contains enough calcium, vitamin B12, and omega-3 fatty acids, as these nutrients are more prevalent in animal foods.

In addition, it can be challenging for people on vegan diets to get enough protein and the right variety of amino acids to maintain optimal health. Most vegan protein sources are considered incomplete, meaning they don't contain all the essential amino acids in the right amounts.

To ensure a healthy and balanced vegan diet, it's important to do your research and consult with a dietitian. It's also crucial to monitor your blood sugar levels regularly, especially if you have diabetes, to stay aware of your blood sugar patterns and notify a healthcare professional if you notice any concerning trends.
