7 Ways to Maintain Healthy Blood Sugar Levels

Updated: Mar. 09, 2021

Here are science-backed diet, exercise, and wellness tweaks that can help you maintain healthy blood sugar levels.

Easy steps to keep blood sugar levels in check

Knowing what is a healthy blood sugar level is important when you have diabetes. What you eat and how much you move helps you avoid highs and lows. Here’s some smart advice to keep healthy blood sugar levels through diet, exercise, and simple lifestyle measures you can take every day.

Enjoy Mediterranean meals

For those who follow a Mediterranean diet, the odds of developing diabetes are 20 to 23 percent lower according to a review of studies published in 2016 in Endocrine. The diet builds meals around plant-based foods, including fruits and vegetables, beans, nuts, whole grains, and olive oil. You eat fish and chicken regularly, but not red meat, butter, or sweets. Phytonutrients and fiber in the plant foods help maintain healthy blood sugar levels, and the olive oil might reduce inflammation. The Mediterranean diet helps keep your glucose levels on an even keel, versus some sneaky things that raise your blood sugar levels.

Go blue

Eating more anthocyanins—the nutrients that give grapes and berries their bright red and blue colors—was linked to healthy blood sugar levels in a study published in 2014 in the Journal of Nutrition. Researchers found that those who consumed plenty of anthocyanins had lower insulin resistance.

Don’t skip breakfast

If you frequently miss a morning meal, you may be more likely to develop type 2 diabetes. Eating breakfast may help stabilize blood sugar levels throughout the day. Prepare a healthy blend of protein, complex carbs, and fat—yogurt mixed with fruit and nuts, for example. Starting the day with lots of simple carbs (such as a bagel and orange juice) is just as bad for your blood sugar as skipping the meal, according to research published in Diabetes Care. (Make sure you are also following these rules to maintain healthy blood sugar levels.)

Sweat and strengthen

Several studies have found that women who did both cardio (at least two and a half hours) and strength training (at least one hour) every week had the lowest diabetes risk. It can be as much as one third less than that of non-exercisers. After an exercise session, your muscles take up more glucose from the bloodstream. As you become more fit over time, cells become more sensitive to insulin.

Step away from the desk (and the TV)

Walk around for two minutes after every 20 you spend sitting down. Many studies have researched the benefits of walking to promote healthy blood sugar levels and lessen spikes in your blood sugar after you eat. A study published in 2013 in Diabetes Care found that three 15-minute daily walks after meals can significantly lower blood sugar levels for mature people. But walking any time is good for people of all ages; just fit it into your day whenever you can.

Calculate your risk

To help you know what is a healthy blood sugar level and whether you are at risk, complete a diabetes risk test, and take the results to your next doctor’s appointment, suggests Robert Ratner, MD, chief scientific and medical officer of the American Diabetes Association. A higher score may spur earlier or more frequent blood sugar checks. Watch that you don’t have these clear signs of high blood sugar.

Examine your medicine cabinet

Drugs for common conditions—such as steroids to control asthma, statins to improve cholesterol levels, and diuretics to lower blood pressure—may raise what is a healthy blood sugar level. Ask your doctor whether other medications can treat your condition without such side effects.
