Diabetes Myths

Do you have diabetes or prediabetes? If so, you may be getting a lot of messages about it. Some of those messages may be conflicting, and some may be difficult to believe. Which information is true, and which should you ignore? These are 7 myths about diabetes, and the truths behind them.


Myth 1: I will get diabetes if I am overweight.

Truth: Not everyone who is overweight gets diabetes, and not everyone who gets diabetes is overweight. Some people who are overweight are metabolically healthy. Physical activity levels, genetics, and whether or not you smoke affect diabetes risk, too. Age is also an important factor, since insulin sensitivity naturally decreases when you get older.

That said, extra weight is the most common risk factor for diabetes. Your risk of developing type 2 diabetes may be 7 times higher if your BMI is 25 to 29.9 (overweight) and by 20 times higher if your BMI falls into the class 1 obese (BMI 30 to 34.9) category compared to if your BMI is under 25 (“normal weight”).[1]

You can calculate your BMI right here. 


Weight gain is another risk factor, with each extra kilogram (2.2 lbs.) you gain raising risk for diabetes by 49% over the next 10 years[2]. As bad as that may sound, take heart: losing a kilogram lowers your risk by 33%!


Myth 2: Eating sugar causes diabetes.

Truth: Eating sugar does not cause diabetes, but it certainly increases your risk. Study after study links sugar consumption to diabetes. The biggest culprits are sugar-sweetened beverages, such as fruit drinks, sodas, flavored coffees, and sports drinks. The reason why sugar leads to diabetes is because it tends to cause weight gain. Sugar may also lead to diabetes by impairing insulin sensitivity, but that is still debatable.

Note that added sugars, not natural sugars, cause these negative effects. The natural sugars in dairy products, such as milk and yogurt, are not linked to diabetes. Neither are the sugars in fruit. In fact, people who eat more fruit may have a lower chance of developing diabetes.[3]


Myth 3: People with diabetes cannot eat carbohydrates.

Truth: Carbohydrates can be a healthy part of your diabetes diet. A few carbohydrates are actually necessary for life. Beyond that, you can choose a carb approach that works for you. Some people with diabetes follow a very low-carb ketogenic diet or a nearly-as-restrictive low-carb diet. These diets exclude grains, most legumes, most fruits, sugary foods, and starchy vegetables. Low and very low-carb diets can lower A1C, but they have questionable long-term benefits. They are difficult to follow for long because they can get boring and do not allow for treats and special occasions. They may also pose threats to heart or kidney health.

A moderate carb approach that focuses on healthy carb sources can also work to control blood sugar. By including 1 to 3 small servings of high-carb foods, such as beans, fruit, or starches, at each meal and snack, you can keep your blood sugar levels more stable. Along with keeping portion sizes down, you can help by choosing nutritious sources of carbs, or sugars and starches.

So, a healthier diet for diabetes limits carbohydrates from added sugars and refined starches, but it should include whole grains and fruit. These are not only linked to weight loss and heart health, but also to better blood sugar control.

Limit or Eliminate... Include Regularly in Moderation...
Added Sugars Fruits and Dairy Products
  • White, brown, turbinado, and other sugar, corn syrup, molasses, honey
  • Sugar-sweetened beverages: soft drinks, energy, fruit, and sports drinks, sweet tea and flavored coffee
  • Cakes, pies, cookies, muffins
  • Ice cream, pudding, custard
  • Candy, sweetened chocolate
  • Jam, jelly
  • Flavored oatmeal and yogurt, sweetened breakfast cereals
  • Fresh fruit
  • Unsweetened frozen fruit such as berries, melon, mango, peaches
  • Low-fat and non-fat milk
  • Low-fat and non-fat plain yogurt and Greek yogurt
  • Reduced-fat cottage cheese and ricotta cheese
  • Cheeses such as parmesan, cheddar, feta, goat, mozzarella, swiss
Refined Starches Nutritious Starches
  • White bread, such as sliced bread, English muffins, bagels, tortillas
  • White pasta and rice
  • Rice cakes, white crackers and pretzels
  • Refined breakfast cereals
  • Potato chips, corn chips, tortilla chips

  • Whole-grain pasta and brown rice
  • Bulgur, quinoa, barley
  • Brown rice cakes, whole-grain crackers and pretzels
  • Whole-grain breakfast cereals
  • Sweet potatoes, potatoes, winter squash, peas, corn, carrots

Myth 4: People with diabetes need to eat special foods. 

Truth: A healthy diet can help people with diabetes control blood sugar better, but the foods do not need to be special. The same types of healthy eating plans that can help improve heart health and control weight can help lower blood sugar. You might choose to follow a Mediterranean-style diet, a DASH (Dietary Approaches to Stop Hypertension) eating pattern, or a general healthy diet based on increasing whole foods and limiting processed foods.

Most people do not need to use special diabetes diet products. Bars, shakes, and other meal replacement and snack options can be expensive and may not offer any benefits over healthy food choices. They can contain highly processed ingredients. Also, eating a bar or drinking a shake may not be as satisfying as eating an entire food-based meal, so these products can get in the way of weight loss in prediabetes or diabetes.


Myth 5:  I would start to feel symptoms if I got prediabetes or diabetes.

Truth: Most people with prediabetes do not get symptoms. In fact, 90% of those with an A1C in the prediabetes range do not know that they have prediabetes.[4] Symptoms of prediabetes could include a softening and darkening of the skin at the back of the neck and under the armpits.

If you have diabetes, you might not have any symptoms, or you may notice one or more of the following symptoms.

Excessive thirst and urination.

  • Increased hunger.

  • Unexplained weight loss.

  • Fatigue.

  • Tingling or numbness in hands and feet.

Since it is impossible to know whether you have diabetes or prediabetes without a blood test, you are best off asking your doctor if you should get tested if you are concerned or if you are overweight, over age 45, or have a family history of diabetes or you had gestational diabetes when you were pregnant.


Myth 6: Everyone with prediabetes will get diabetes.

Truth: About two out of three people with prediabetes develop type 2 diabetes eventually, but there is a good chance that you do not need to be among them! Research shows that while prediabetes develops into diabetes if you do nothing, you can dramatically lower your risk for developing diabetes with simple lifestyle changes. Losing as little as 7 percent of your body weight - about 12 to 18 pounds for many people - can cut your risk of diabetes by over half, and each of the following changes can add to that effect.

  • Increasing physical activity.

  • Eating more leafy greens and whole grains.

  • Eating less fried food and sugar.

  • Drinking water instead of sugar-sweetened beverages.

  • Avoiding tobacco.

  • Getting adequate sleep.


Myth 7: Diabetes is no big deal.

Truth: Diabetes is a huge deal. The only thing about diabetes that is “no big deal” is that a lot of people have it. Other than that, diabetes takes a lot of time to manage, it is expensive, and it can lead to serious health problems.

Diabetes management requires a lot of time and effort on your part. People with diabetes may need to measure blood sugar one or more times every day. You may be on one or more prescription medications, including insulin that may need to be injected one or more times per day. You will need to attend medical checkups with a regular doctor and specialists such as a kidney and food doctor.

Aside from the nuisance, and the cost of paying for medications and medical care, diabetes causes health concerns. Complications can include blindness, kidney disease, foot problems, and neuropathy. Diabetes also increases the risk for heart disease, kidney disease, stroke, and hypertension.

Diabetes and Rice

Do diabetes and rice mix? Will eating rice raise your A1C and blood sugar levels if you have diabetes? Does rice cause type 2 diabetes?

Rice pilaf, risotto, fried rice, steamed rice, rice casseroles and soups, and other rice dishes may taste good and be satisfying, but rice is high in carbohydrates. That may leave you questioning  how rice affects blood sugar and whether it is okay to eat rice if you have type 2 diabetes or are worried about getting diabetes. Here is what you need to know about how rice can affect blood sugar and insulin, and how you can make rice a healthy part of your life.


White Rice, Brown Rice, and Diabetes Risk

Does white rice put you at risk for type 2 diabetes? It appears to. Research has found that people who eat higher amounts of white rice are more likely to develop type 2 diabetes compared to people who eat almost none.[1, 2]

On the other hand, brown rice appears to have the opposite effect. Not only does brown rice not cause diabetes, but it actually seems to protect against it. That is, people who eat more brown rice have a lower risk for diabetes. 

White versus Brown Rice

Brown rice is the unprocessed form of the grain, while white rice is the more processed form. Brown rice still has the high-fiber bran, high-nutrient germ, and starchy endosperm components, while white rice has only the starchy endosperm. Any variety of rice, whether jasmine, basmati, or arborio, can be white or brown, depending on its processing.

Is Rice Bad for Diabetes?

Is it okay to eat rice If you have diabetes? It depends. Rice has a high glycemic index and a lot of carbohydrates. That means that rice can quickly raise blood glucose to very high levels. Eating a lot of high-glycemic foods can increase insulin resistance and make it harder to control your blood sugar.

Brown rice, though, appears to be healthier. It is just as high in carbs and has a glycemic index that is only slightly lower than that of white rice, but it increases insulin sensitivity. It causes slightly less of a blood sugar spike after meals compared to white rice. Furthermore, brown rice has the heart-healthy benefits of lowering total and “bad” LDL cholesterol.[3] That is good news if you have diabetes, since diabetes is already a risk factor for heart disease!


Does Rice Have Sugar and Carbohydrates?

Rice does not have sugar in it, but it does have starch - a lot of starch. Sugars and starches are both types of carbohydrates. Starch is a complex carbohydrate made up of many pieces of a type of sugar called glucose. When you eat rice, your body breaks down the starch into its glucose components and releases the glucose into your bloodstream. This raises your blood glucose or blood sugar levels. That is why eating rice is like eating a sugary food even though it has no sugar.

Rice is almost pure carbohydrate. A cup of cooked rice has 45 grams of carbs. White rice has almost no fiber, with only 0.6 grams per cup. Brown rice has 3.5 grams. Fiber helps lower blood sugar and has other benefits, such as lowering cholesterol.

To put rice in perspective, the following table shows the amount of carbohydrates and fiber in various foods.

Food Carbohydrates, Grams Fiber, Grams
White rice, 1 cup cooked
Brown rice, 1 cup cooked
Whole-grain pasta, 1 cup cooked
Barley, 1 cup cooked
Whole-grain bread, 1 thick slice
Oatmeal, 1 cup cooked
Sweet potato, 1 cup mashed
Lentils, ½ cup cooked
Corn, 1 cup

Healthier Meals with Rice

You can fit rice into a healthy diet for preventing or managing diabetes and blood sugar by being careful. Brown rice is a more nutritious choice that is better for blood sugar than white rice. Choose brown rice and products such as brown rice noodles, brown rice cakes, and brown rice crackers instead of white rice products. Regardless of which type of rice you choose, keep portion sizes in mind. A side order of rice can have over 150 grams of carbohydrates, which is more than enough for an entire day for some people. A good goal is to stick to ½ to 1 cup.

You can make your meal or snack healthier by adding low-carb foods with protein, healthy fats, and fiber to lower the glycemic index and stabilize your blood sugar levels.

Some Healthy Rice Ideas

  • Veggie burger with brown rice and ingredients such as beans, carrots, cashews, tomatoes, mushrooms, onions, oats, and bell peppers.
  • Stuffed bell peppers or eggplants with a filling containing brown rice, lean ground turkey, tomato sauce, diced onion and tomato, and chopped water chestnuts or walnuts.
  • Broccoli rice casserole with brown rice, broccoli, onions, spices, milk, and cheese, and crushed pecans on top.
  • Chicken and brown rice soup with vegetables such as carrots, celery, onion, sweet potato, zucchini, and corn.
  • Salad with romaine lettuce tossed with brown rice, fat-free refried beans, cheddar cheese, tomatoes, avocado, and fat-free plain yogurt.

Sometimes, you might want to choose alternatives to rice that are higher in fiber or lower in carbs. Higher-fiber and lower-carb foods can keep prevent spiking blood sugar when you have diabetes. These are some examples.

  • Wheat bran and shredded wheat instead of puffed rice

  • Oatmeal instead of cream of rice or hot rice cereal.

  • Barley, sweet potatoes, or beans in soups or for side dishes.

  • Pulverized “riced” cauliflower as a substitute for rice in recipes.

  • Shredded cabbage or broccoli instead of rice in fried rice.

  • Raw vegetables or roasted soybeans instead of brown rice cakes.

Is rice bad for diabetes? The answer is a bit complicated! Too much white rice can raise risk for type 2 diabetes and increase blood sugar when you have diabetes, but moderate amounts of brown rice can be good for diabetes. It can be hard to figure out what to eat when you have diabetes or are trying to prevent it, but Lark Diabetes and Lark DPP can help. As your personal health coach, Lark can guide you towards healthier eating for blood sugar control and weight loss, along with the other healthy habits that can keep you as healthy as possible.
