DIABETES DIET: HOW THE MEDITERRANEAN PLAN HELPS LOWER RISK

Managing blood sugar can feel confusing, especially when advice seems to change with every new diet trend. But experts agree on one thing: food plays a powerful role in preventing-and even controlling-type 2 diabetes. The right eating habits can steady glucose levels, improve insulin sensitivity and reduce your risk of serious complications. Here's what doctors and dietitians say about the best diabetes diet and the simple swaps that make a big difference.

What is type 2 diabetes?

Let's start by understanding type 2 diabetes 

"People with type 2 diabetes experience high blood sugar (or blood glucose) levels because their body either doesn't produce enough insulin or because the body doesn't respond properly to the insulin available," explains registered dietitian Gigi Kwok-Hinsley, DrPH, MS, RDN, a scientist at Amway. "Either situation prevents the sugars from being used as a source of nutrients and energy and may result in symptoms such as fatigue, constant thirst, dry skin or blurred vision."

Many people with type 2 diabetes use medication such as Metformin to improve insulin sensitivity and reduce blood sugar, but following a diabetes diet can have similarly beneficial effects. 

Is Diabetes Hereditary? How to Reduce Your Risk If It Runs in the Family

How the Mediterranean diet could lower diabetes risk

If a chronic illness like type 2 diabetes runs in your family, avoiding it may feel impossible. But in most instances, type 2 diabetes is preventable with a healthy diet and consistent exercise. There are many opinions on what the healthiest diet looks like, whether it's low-carb, paleo or something else, but new research suggests we should all consider the Mediterranean diet, especially if lowering diabetes risk is the goal.

"The Mediterranean diet is really just eating the way people around the Mediterranean have eaten for centuries," says Phyllis Pobee, MD, a triple-board-certified physician and founder of GeneLean360°. What does that mean? "Lots of vegetables, fruits, beans, nuts, fish, olive oil, some whole grains and not much red meat or processed food."

And it has powerful effects on diabetes risk. In a new study in Annals of Internal Medicine, co-led by researchers at the Harvard T.H. Chan School of Public Health, researchers followed 4,746 adults in Spain between the ages of 55 and 75 who were overweight or obese but did not have type 2 diabetes. Over 6 years, participants who followed a Mediterranean diet, cut 600 calories from their daily diet and walked briskly for 45 minutes a day six days a week lowered their risk of developing type 2 diabetes by 31 percent and lost an average of 3.7 percent of their body weight. 

Parth Bhavsar, MD, a board-certified family medicine physician with extensive clinical experience in urgent care, virtual primary care and telehealth, says the Mediterranean diet works to combat type 2 diabetes because of the way its healthy fats and fiber impact insulin.

"To understand how it lowers diabetes risk, you must understand at a conceptual level what diabetes is," says Dr. Bhavsar. "Type 2 diabetes is largely caused by inability or decreased ability of tissues to utilize the floating sugar in the bloodstream due to insulin resistance. The Mediterranean diet, due to its properties mentioned above, improves insulin sensitivity; therefore, more sugar is taken up by the tissues to be burned as fuel, resulting in less sugar in the bloodstream, which equals less diabetes risk."

Expert-approved Mediterranean diet meals 

If you're ready to use the Mediterranean diet to lower your risk of diabetes but aren't sure where to start, our experts shared a few deliciously easy toss-together ideas for creating Mediterranean-inspired meals:

Breakfast: Greek yogurt with walnuts and berries: "The combination of healthy fats with fiber and protein causes slowing of digestion and decreases blood sugar spikes," says Dr. Bhavsar.

Lunch: Feta and chickpea salad with olive oil: "Fiber lowers glucose spikes and olive oil helps with lipid metabolism," says Dr. Pobee. 

Dinner: Barley with tahini and roasted veggies: "Beta-glucan in barley helps insulin sensitivity and tahini adds minerals and healthy fats," says Dr. Pobee. 

Snack: Sliced carrots and peppers with hummus: This protein-rich snack is packed with fiber-without the refined carbs in most crackers and chips.

4 Foods That Lower Your Blood Sugar Fast-Including Potatoes!

More foods to enjoy on a diabetes diet

1. Vegetables

"Vegetables are often chock full of fiber that slows digestion," Kwok-Hinsley says, and nonstarchy veggies are your best bet. This moderates the amount of glucose that enters your bloodstream, keeping blood sugar within the healthy range. 

Cory Rice, DO, a functional medicine doctor and chief clinical advisor at Biote, adds, "‘leafy green vegetables such as spinach and kale, along with cruciferous vegetables such as broccoli, cauliflower and cabbage," are especially beneficial. These "are very effective at both glycemic control and insulin response."

2. Fruits

Many type 2 diabetics avoid fruit because of its sugar content, but Morgan Walker, MS, RD, LDN, a registered dietitian, sports nutritionist and adjunct professor at Lebanon Valley College says that isn't necessary. "The fiber in many fruits helps slow down the absorption of sugar, preventing rapid spikes." What's more, certain fruits are low-glycemic, meaning they're less likely to cause blood sugar fluctuations.

Low-glycemic fruits include cherries, grapefruit, peaches, apples and pears. "These fruits tend to have a higher fiber content and are nutrition-dense, which helps glycemic response," explains Dr. Rice. Just be sure to opt for fresh or frozen whole fruit over canned or dried fruit, since the latter often has more sugar.

3. Beans and legumes

"The fiber and protein [in beans and legumes] slow the absorption of sugar in the bloodstream and help stabilize blood sugar levels," Walker says. Beans and legumes also contain vital nutrients like iron and magnesium and are low in fat, "making them a heart-healthy choice." 

Some of the most nutrient-dense picks are black beans, chickpeas, lentils, kidney beans, split peas and pinto beans.

4. Nuts

"Because nuts are a source of healthy fat and protein, they don't spike blood sugar," notes Kwok-Hinsley. "There isn't one nut that is superior overall, but research has shown that almonds, walnuts, pistachios and cashews can support those on a type 2 diabetes diet."

Walker recommends enjoying nuts in small amounts because, while healthy, they're calorie-dense. Likewise, she encourages you to "opt for unsalted, raw or dry-roasted versions to avoid added sodium." 

5. Lean protein

Protein is a key part of a healthy type 2 diabetes diet. Kwok-Hinsley says protein helps you feel fuller longer, prevents blood sugar from spiking and assists in building muscle. Research in The American Journal of Clinical Nutrition confirms that increased protein intake lowers blood sugar after eating and improves overall blood sugar control. Kwok-Hinsley recommends lean proteins such as fish (cod, halibut, haddock), skinless chicken, turkey and soy (tofu).

6. Cinnamon

"Research shows that cinnamon may play a role in improving blood glucose management, as it might enhance insulin sensitivity when consumed regularly," she says. "Try sprinkling cinnamon on oatmeal, yogurt or baked sweet potatoes for a flavorful and beneficial addition to your meals."

Indeed, a study in the International Journal of Food Science found that consuming 3 to 6 grams of cinnamon (about 1-2 tsp.) daily improved insulin resistance and helped keep blood sugar levels stable. 

How to stick to a diabetes diet when eating out

Wondering how to stick to a healthy eating plan-and still satisfy your taste buds-when eating out? These tips make it easy:

Go for grilled fare

"It's always a little tricky when you explore a restaurant's menu," Kwok-Hinsley says. "It's not immediately clear what ingredients are in the sauce or what cooking process the kitchen used." A safe bet? "Opting for lean proteins like chicken or fish that are grilled, baked or steamed. 

Dr. Rice says that "focusing on lean protein while dining out helps you feel full so that you don't want to eat as much sugar or starchy, carbohydrate-filled food" that can spike your blood sugar.

Swap your sip

Try trading alcohol, which Dr. Rice says "dramatically drives blood sugar up and increases cravings for sweets and carbs" for a sparkling water. This helps keep your glucose levels in check.

Kwok-Hinsley adds that water is always the best option, as many beverages contain a surprising amount of added sugar. But "if you want more flavor, unsweetened iced tea and regular tea are good options."

Order off the kids' menu

"My favorite trick to managing portion size is to order kids' meals, which often have fewer side dishes or smaller portions," Kwok-Hinsley shares.  "Or, you can order a kids' meal and add a side of vegetables or salad so the portion is slightly bigger but still not quite the size of a regular entree." 

Save carbs for last

Turns out the order you eat your food can help play a role in steadying your blood sugar. "Clinical evidence suggests that consuming vegetables first followed by protein and then carbohydrates, helps reduce post-meal blood sugar spikes," Dr. Rice says.

"People with diabetes don't have to avoid starchy carbohydrates like rice, pasta and breads altogether, but make sure these foods don't fill more than half of your plate and try to pair them with high-fiber carbohydrates, lean proteins and healthy fats," Kwok-Hinsley adds.

The bottom line on eating a diabetes-friendly diet
