You got the news and you have Gestational Diabetes.

Yet what you need is a Gestational Diabetes diet for Vegetarians, is there such a thing?

Well you have come to the right place.

You have been instructed by your doctor or registered dietitian to have a carbohydrate controlled diet and to increase your protein intake. 

However, because you are a vegetarian you are worried you may not have a balanced enough meal to control your blood sugar levels.

I get it, it can be overwhelming but vegetarians that are pregnant with gestational diabetes can have a variety of nutrients in their diet, if well planned.

This comprehensive article will explain the science behind gestational diabetes and help you understand the best diet for vegetarians to help manage your blood sugar levels.

What does my body normally do with its blood sugar levels?

When you eat food, your body breaks down that food into simple sugar. Therefore, simple sugar is easily absorbed into your bloodstream for energy use or is stored for later use. If you have a lot of sugar in your bloodstream, your body responds by releasing insulin which is the key that lets all that extra sugar out of your blood and into your body for use.

Insulin is a hormone that is made by the pancreas, the pancreas releases this hormone to help control sugar levels in the bloodstream. It controls it by removing the blood sugars out to the liver, the liver then transforms it to fat as storage for future energy use.

Sometimes the pancreas cannot release the correct amount of insulin and will manifest as Diabetes. 

In the case of a pregnant woman, the change of hormones throughout her body creates an environment where sugar levels are difficult to control. The body has a difficult time keeping up with your body demands.

What is Gestational Diabetes?

Called pregnancy diabetes, it comes only during pregnancy and goes away as soon as you give birth.

Your body is doing a great feat of creating another human being, and your body sure feels the burden.

Although not every woman that is pregnant will develop gestational diabetes, there are risk factors that can increase the possibility of developing it.

-A big risk factor is obesity prior to pregnancy

As your nutritional needs increase over time, you may become increasingly bored with these options. What if i told you that it’s possible to still eat well and not get bored. The key is to make sure that you have variety within your restrictions.

What is also important to keep in mind is that snacks can be your source of plant-based proteins. Having a snack that is protein based can help you feel full longer as well as help you manage your serving size. Having long stretches without food can cause you to struggle in controlling your serving size out of increased hunger.

The first thing to remember is to have a carbohydrate that is complex, this means a whole grain type of carbs. These grains can be bread, tortillas, oatmeal, cereal, and farina.

Next, add your protein source from the list mentioned above.

If possible, add a veggie to complement your meal.

Fat is also important and with a small amount can give your food flavor and help you feel full longer. Fats can be found in butter, mayonnaise, dressings, vegetable oil, olive oil, some nuts and seeds.

Depending on your lifestyle, lunch can be easy to arrange or difficult. If thinking of lunch makes you feel overwhelmed, you are probably not prioritizing its importance. At this stage, with a diagnosis of gestational diabetes it has to become a priority to make sure you have a healthy baby after giving birth.

The same thing applies to lunch, a balance of carbs, protein and fat.

Depending on the recommendation from your Registered Dietitian, you may need to eat snacks. Some may recommend 1, 2, or 3 snacks. 

The following are some examples that can help you get an idea of what a vegetarian snack can be. 

Snack Option 1
