Your Guide to a Low-Glycemic Vegan Lifestyle

This article will walk through the vegan diet, what foods are low GI that you should include in a vegan diet, and what foods to minimize. You’ll find meal and snack ideas and tips to help you follow a lower-GI diet. 

Let’s start with a quick overview of the glycemic index and the vegan diet. 

Foods that are high on the glycemic index are refined carbohydrates, meaning they are often high in sugar and low in fiber, fat, and protein. Foods that fall lower on the GI index are whole grains, vegetables, fruits, beans, nuts, seeds, most dairy products, and meats. 

When you do eat foods higher on the glycemic index it is just important to know how to combine them with foods high in protein, fat, and fiber. This will help slow their absorption and will help keep your blood sugar stable.

What Does It Mean to Follow a Vegan Diet?

A vegan diet eliminates all animal foods and ingredients from animal sources. It focuses on fruits, vegetables, and grains with protein coming from beans and legumes, nuts, and seeds. 

A recent study looked at the effects of a vegan diet on blood sugar control in people with type 2 diabetes and those at risk for type 2 diabetes¹. The results found that despite the vegan diet being high in carbohydrates, those following it had reduced blood glucose levels, better glycemic control, and improved insulin sensitivity. They also had reduced body weight, improved cholesterol and lipid levels, and lower blood pressure¹.

So a vegan diet may sound like the perfect way to eat if you are on a low glycemic diet, but there can be pitfalls if you aren’t careful. Many of the foods on a vegan diet are high in carbohydrates, so knowing what to eat, what to limit, and how to combine food into a meal is important.  

Let’s explore what you should eat and things to avoid if you are following a vegan, low GI diet. 

Foods to Eat on a Low-Glycemic Vegan Diet

• Grains: Whole grains, like quinoa, brown rice, oatmeal, and barley all make a good base for a meal. 
• Beans & Legumes: Fiber-rich beans like chickpeas, black beans, or lentils give a nice protein boost. 
• Soy: Edamame, tofu, and soy protein powders are good sources of protein and low-glycemic².
• Fruits: Apples, pears, apricots, peaches, plums, berries are lower on the glycemic index.
• Nuts andSeeds: Walnuts, almonds, pecans, nut butter, chia seeds, flax seeds, and pumpkin seeds all contain protein and are good sources of other nutrients important for vegans.  
• Vegetables: Non-starchy vegetables like leafy greens, asparagus, broccoli, Brussels sprouts, mushrooms, and cauliflower are all low on the glycemic index. 
• Healthy Fats: Avocado, grapeseed oil, olive oil 
• Starchy Vegetables: Corn, peas, winter squash, and potatoes can be paired with lower glycemic foods along with fat and protein which will help slow the rise in your blood sugar.

Foods to Avoid on a Low-Glycemic Vegan Diet

Are there foods that aren’t great choices for someone wanting to follow a low-glycemic vegan diet? 

• Refined Grains: White bread and rolls, white rice, enriched white pasta, pancakes, waffles, and chips.
• Pastries: Cookies, cakes, and candy
• Sugary Drinks: Soft drinks, kombucha, sweetened tea, and energy drinks
• Cereals and Cereal Bars: Sugar-coated and refined cereals, some instant oatmeals, granola bars, cereal bars.
• Agave: Even though it’s vegan and low glycemic, agave is essentially concentrated fructose. Overconsumption of agave can lead to excess fat stored in the liver (the liver is the only place that fructose can be stored).

Many of these foods aren’t great sources of nutrition anyway. But if you are going to enjoy these, pair them with something that is high in fat and protein. Fat and protein help lower and slow the rise in your blood sugar and keep it more stable.

How to Make Sure You’re Getting Enough Nutrients on a Low-Glycemic Vegan Diet

Because a vegan diet eliminates all animal products, you need to pay extra attention to making sure you are getting the nutrients your body needs. There are some vitamins and minerals that are primarily found in animal products and may be lacking in a vegan diet. 

A recent systematic review found that people who follow a vegan diet do have lower intakes of riboflavin, niacin, vitamin B12, vitamin D, iodine, zinc, calcium, potassium, and selenium. The study also found lower intakes of protein than people following a western diet³.

The good news is that many lower GI foods are still good sources of most of these nutrients and by eating a variety of foods you can make sure you get all the nutrition you need. 

For instance, while meat is an excellent source of B vitamins including riboflavin and niacin, you can find those in whole grains. Beans, nuts, and seeds, in addition to being a primary source of protein for vegans, and are also a good source of zinc and omega-3 fatty acids. Leafy greens and soy products including tofu and soy milk are good plant-based sources of calcium.^{4, 5, 6, 7}

Tips for Following a Low-Glycemic Vegan Diet

There are three easy tips to keep in mind if you are following a low-glycemic vegan diet. 

1. Focus on eating protein at each meal: Protein will help slow the absorption of those higher carbohydrate/ higher GI foods. Foods like tofu, beans, nuts, and nut butter are good choices.
2. Aim for at Least 5 Grams of Fiber at Each Meal: Fiber will help keep you full longer and will also slow the absorption of higher GI foods.‍
3. Eat a Variety of Food: It’s easy to get into a rut, especially for breakfast and lunch, but do your best to mix it up a bit so you get a variety of nutrients every day. This will help ensure you get all the nutrients your body needs.
