The Effects of Celery on Blood Sugar Levels

All carbohydrate-rich foods are likely to have some sort of effect on your blood glucose. Celery is high in fiber and contains very low amounts of digestible carbohydrates in the form of sugars. Ultimately, the crunchy stalks aren't likely to have drastic effects on your blood glucose. Due to its fiber content, celery may actually be a good tool to help keep your blood glucose levels under control.

Sugar Processes

Your body can't tell the difference between added sugar in a candy bar and natural sugar from a stalk of celery. All sugars wind up as simple carbohydrate molecules in the form of glucose, which become your body's main fuel source, according to the Mayo Clinic.

Every fruit or vegetable lands somewhere on the glycemic index, a measuring tool that classifies carbohydrate-containing foods by their ability to raise blood sugar levels, according to the Mayo Clinic. While fruits like bananas are a little higher on the glycemic index, celery lands on the lower end of the spectrum, according to the New Hanover Regional Medical Center.

Insulin’s Role

When glucose hits your blood, your body produces insulin, a hormone that regulates sugar absorption, according to the Mayo Clinic. Insulin forces glucose into cells to give them the energy they need to work.

However, if glucose isn't needed, insulin allows cells to store the fuel for later. Without adequate insulin, sugar stays circulating in your blood, leaving you with abnormally high blood sugar. Luckily, celery isn't high in carbohydrates and shouldn't raise blood sugar levels too high.

Fiber’s Effects

Although fiber is a type of carbohydrate, like sugars and starches, it's processed differently. The human body can't fully deconstruct fiber, leaving it primarily intact as it travels through your gut, according to the Mayo Clinic. This can help normalize digestion and promote satiety.

Although fiber doesn't turn into glucose, it can still affect your blood sugar. Soluble fiber turns into a jelly-like substance when it binds with fluid in your gut, according to the Mayo Clinic. This material slows digestion as a whole, including delaying sugar absorption. As a result, your blood glucose is more likely to stabilize. As celery is high in fiber, it can help keep your blood sugar under control.

Your Carbohydrate Allowance

If you're managing prediabetes or diabetes (or simply want to control your blood sugar) you have to keep track of the carbohydrates you consume at each meal. Generally, you should start out with about 45 to 60 grams of carbs at each meal, the American Diabetes Association recommends.

This basic carb recommendation includes both digestible sugar and starch carbohydrates — the ones that have a direct effect on blood sugar. One medium size stalk of celery has less than 2 grams of carbs, making this a safe food that won't affect your blood glucose too much.
