50. Agave and Other ‘Natural’ Sweeteners Agave syrup and other so-called “natural” sweeteners, such as honey, maple syrup, and coconut sugar, are often promoted as healthier… Alina Yasinskaya - September 4, 2025

According to the CDC, over 37 million Americans have diabetes and 96 million more have prediabetes. The pancreas produces insulin, a hormone vital for keeping blood sugar in check. When insulin function is impaired, blood glucose can rise to dangerous levels. Unfortunately, diabetes often develops silently, with symptoms appearing only after significant damage. Identifying and managing blood sugar spikes early is crucial for long-term health and preventing complications.

White bread is a staple in many diets, but its impact on blood sugar can be significant. Made from refined grains, white bread is stripped of fiber and essential nutrients during processing. As a result, it digests quickly and rapidly converts to glucose in the bloodstream, causing sharp spikes in blood sugar levels. This effect can be particularly concerning for those with diabetes or prediabetes, as frequent blood sugar spikes contribute to insulin resistance and long-term health complications.

Research from the Harvard T.H. Chan School of Public Health highlights that refined grains like white bread have a high glycemic index (GI), meaning they cause a rapid increase in blood glucose. Consuming high-GI foods regularly can make blood sugar management much more difficult. Instead, choosing whole grain alternatives such as whole wheat bread, rye, or multigrain options can help slow digestion, reduce blood sugar spikes, and support overall metabolic health. Reading labels and opting for breads with at least 3 grams of fiber per slice is a practical way to make healthier choices and stabilize blood sugar throughout the day.

2. Sugary Breakfast Cereals

Many breakfast cereals marketed as healthy options are actually loaded with added sugars. These sugars are quickly absorbed by the body, leading to rapid blood sugar spikes shortly after consumption. For individuals trying to manage their blood sugar, starting the day with a sugary cereal can set a challenging precedent for the rest of the day’s meals. According to the Environmental Working Group (EWG), some popular cereals like Frosted Flakes and Froot Loops contain more than 10 grams of sugar per serving, rivaling the sugar content found in many desserts.

The combination of refined grains and added sugars in these cereals offers little fiber or protein to slow digestion and blunt the blood glucose response. In contrast, cereals made with whole grains and minimal or no added sugar—such as plain oatmeal, shredded wheat, or unsweetened muesli—provide more stable energy and better support for blood sugar control. Checking nutrition labels for sugar content and choosing options with at least 3 grams of fiber per serving are practical steps. For more information on making smarter cereal choices, see CDC’s guide on choosing breakfast cereal.

3. Soda and Sweetened Beverages

Soda and other sweetened beverages are among the leading contributors to excessive sugar intake. Unlike solid foods, the sugars in these drinks are in liquid form, allowing for extremely rapid absorption into the bloodstream. This can result in immediate and dramatic blood sugar spikes, putting significant stress on the pancreas and increasing the risk of insulin resistance over time. According to the Centers for Disease Control and Prevention (CDC), nearly half of all added sugars in the American diet come from beverages like soda, energy drinks, and sweetened teas.

Real-world data reveals that, on average, Americans consume about 38 gallons of sugary drinks per person each year, as reported by the Statista. This high intake is linked to a greater risk of type 2 diabetes and other metabolic conditions. To help stabilize blood sugar, it is advised to limit or eliminate sweetened beverages and opt for water, unsweetened tea, or sparkling water instead. Reading labels and being mindful of serving sizes can further help reduce unnecessary sugar consumption and its harmful effects.

4. White Rice

White rice is a dietary staple worldwide, but it can cause significant blood sugar spikes due to its high glycemic index. During processing, white rice is stripped of its bran and germ, removing much of its fiber, vitamins, and minerals. As a result, it is digested and absorbed quickly, leading to a rapid rise in blood glucose levels. This makes white rice a risky choice for individuals with diabetes or those aiming to maintain stable blood sugar.

In contrast, brown rice retains its bran and germ, providing more fiber and nutrients. This slows down digestion and leads to a more gradual increase in blood sugar. Research from the Harvard T.H. Chan School of Public Health found that substituting white rice with brown rice or other whole grains can significantly lower the risk of type 2 diabetes. For those who enjoy rice, serving tips include mixing brown and white rice to transition your palate, pairing rice with high-fiber vegetables or lean proteins, and keeping portions moderate. These strategies help blunt the blood sugar response and improve overall dietary quality.

5. Pastries and Doughnuts

Pastries and doughnuts are popular treats, especially as breakfast options, but their combination of high sugar and unhealthy fats can be particularly problematic for blood sugar control. These baked goods are typically made with refined flour, significant amounts of added sugar, and trans or saturated fats, creating a food that is quickly digested and absorbed. This leads to an immediate spike in blood glucose, followed by a rapid drop that can cause cravings and energy crashes. The American Heart Association warns that foods high in both sugar and fat, such as breakfast pastries, may increase the risk of insulin resistance and heart disease (source).

Even a single doughnut or frosted pastry can contain more than a day’s recommended sugar intake and a significant amount of unhealthy fat. To moderate consumption, consider limiting these items to special occasions, sharing portions, or opting for healthier homemade versions using whole grain flour and less sugar. Pairing a small serving with protein-rich foods, like Greek yogurt or eggs, can also help stabilize blood sugar. Practicing mindful eating and savoring these treats occasionally rather than habitually is key to managing their impact on health.

6. French Fries

French fries are a favorite comfort food, but their effect on blood sugar can be quite harmful. Potatoes themselves are a high-glycemic food, rapidly converting to glucose once digested. When potatoes are fried, their glycemic load increases further due to the breakdown of starches and the addition of unhealthy fats. This process creates a food that not only spikes blood sugar quickly but also adds excess calories and saturated fat, contributing to insulin resistance and weight gain. According to the Harvard T.H. Chan School of Public Health, frequent consumption of fried potatoes is associated with a higher risk of type 2 diabetes.

In contrast, boiled or baked potatoes have a lower glycemic load, especially when consumed with the skin, which provides additional fiber. To make potatoes a healthier part of your diet, consider alternatives like oven-baked fries made with olive oil, roasted sweet potatoes, or mashed cauliflower. These swaps reduce the glycemic impact and add valuable nutrients. Pairing potatoes with lean protein or high-fiber vegetables can further slow glucose absorption, making it easier to maintain stable blood sugar levels throughout the day.

7. Flavored Yogurts

Flavored yogurts are frequently marketed as healthy snacks, but many varieties contain significant amounts of hidden sugars. These added sugars are often used to enhance flavor, especially in fruit-flavored or dessert-inspired yogurts, turning what should be a nutritious option into a potential source of blood sugar spikes. According to the U.S. Food and Drug Administration (FDA), some flavored yogurts can contain as much as 20 grams of sugar per serving, with much of it added rather than naturally occurring.

In contrast, plain yogurt—particularly Greek or Icelandic styles—contains far less sugar and more protein, which helps curb appetite and blunt blood glucose responses. For a healthier option, choose plain, unsweetened yogurt and add fresh fruit or a sprinkle of cinnamon for natural sweetness. Reading nutrition labels carefully is essential: look for “added sugars” in the ingredients list and compare sugar content between brands. Opting for yogurts with fewer than 8 grams of total sugar per serving and higher protein content can help support better blood sugar management while still providing the benefits of probiotics and calcium.

8. Sports and Energy Drinks

Sports and energy drinks are widely consumed for their promise of quick hydration and energy, but their high sugar content can lead to dangerous blood sugar spikes. Many popular brands contain between 20 and 34 grams of sugar per bottle, equivalent to nearly eight teaspoons. These drinks are often marketed to athletes, yet most people who consume them do not engage in the intense physical activity that would require such rapid carbohydrate replenishment. According to the Centers for Disease Control and Prevention (CDC), sports drinks are a leading source of added sugars among children and adolescents in the United States.

In everyday scenarios—such as during a workday, light exercise, or casual social events—reaching for a sports or energy drink can flood the bloodstream with glucose, creating a rollercoaster effect in blood sugar levels. This can be especially problematic for those with or at risk of diabetes. The best approach is to hydrate with water, which meets most hydration needs without added sugar or calories. If extra electrolytes are necessary, look for low-sugar or sugar-free alternatives. Reading labels and being mindful of actual hydration needs can help prevent unnecessary spikes in blood sugar.

9. Granola Bars

Granola bars are often perceived as a healthy, convenient snack, but many commercial options are packed with added sugars and syrups. These ingredients, intended to improve taste and texture, can cause blood sugar to spike rapidly after consumption. According to the Harvard T.H. Chan School of Public Health, some granola bars can contain as much sugar as a candy bar—sometimes more than 12 grams per serving—making them a less ideal choice for blood sugar management.

Homemade granola bars, on the other hand, offer greater control over sugar content and ingredient quality. By using whole grains, nuts, seeds, and natural sweeteners in moderation, you can create a snack that is more filling and less likely to cause glucose spikes. When buying prepackaged bars, it’s important to read nutrition labels carefully. Look for options with less than 6 grams of added sugar per serving, at least 3 grams of fiber, and some protein to help maintain steady energy. Choosing bars with whole food ingredients and minimal additives can help you enjoy the convenience of granola bars without the risk of dangerous blood sugar surges.

10. Pizza Crust

Pizza is a beloved meal for many, but the traditional pizza crust poses significant challenges for blood sugar management. Most pizza crusts are made from refined white flour, which is quickly digested and converted into glucose, leading to swift blood sugar spikes. The lack of fiber in refined flour means there is little to slow the absorption of carbohydrates, making it especially risky for those with diabetes or prediabetes. The American Diabetes Association notes that refined flour-based foods like standard pizza crust can contribute to higher post-meal glucose levels.

Fortunately, there are healthier alternatives for pizza lovers. Whole wheat or whole grain crusts contain more fiber and nutrients, which help moderate blood sugar responses. Cauliflower crusts and other vegetable-based options offer even lower carbohydrate content and higher nutrient density. When choosing or making pizza, opt for thin crusts, add plenty of non-starchy vegetables, and include lean protein to further blunt glucose spikes. Reading ingredient lists and nutrition labels in restaurants or on frozen pizzas can also help you make smarter choices while still enjoying this favorite food in a more blood sugar-friendly way.

11. Instant Oatmeal Packets

Instant oatmeal packets are a popular breakfast choice for their convenience, but they often come with hidden drawbacks for blood sugar control. Many flavored varieties contain added sugars, sometimes up to 12 grams per serving, which can lead to rapid glucose spikes. Additionally, the oats in these packets are processed to cook quickly, resulting in a higher glycemic index (GI) compared to less processed oats. This means instant oatmeal is broken down and absorbed faster, causing blood sugar to rise quickly after eating. The Harvard T.H. Chan School of Public Health points out that steel-cut or old-fashioned rolled oats have a lower GI and provide more sustained energy.

For a healthier alternative, choose plain steel-cut or old-fashioned oats and add your own toppings such as fresh fruit, nuts, or cinnamon for flavor without excess sugar. Preparing oats in advance, such as overnight oats or batch-cooked steel-cut oats, can make healthy breakfasts just as convenient as instant packets. Reading ingredient lists and avoiding options with added sugars or artificial flavors can help you enjoy the benefits of oats without the blood sugar rollercoaster.

12. Pretzels

Pretzels are a popular snack, often chosen for their low fat content and crunchy texture. However, most traditional pretzels are made from refined white flour and contain little to no fiber or protein. This composition causes them to be rapidly digested and absorbed by the body, resulting in sharp and quick blood sugar spikes. According to the American Diabetes Association, snacks made primarily from refined grains, such as pretzels, offer minimal nutritional benefit and can make blood sugar management more difficult.

When compared with whole grain snacks—such as roasted chickpeas, air-popped popcorn, or whole grain crackers—pretzels fall short in promoting satiety and stable energy. Whole grain options provide more fiber, which slows digestion and helps keep blood glucose levels steadier. To reduce the risk of blood sugar spikes, consider limiting pretzel portions and pairing them with a source of protein or healthy fat, such as nuts or hummus. Reading nutrition labels and choosing products labeled “whole grain” can assist in making better snack choices. Practicing portion control, such as pre-measuring serving sizes, can also help prevent overconsumption.

13. Crackers

Crackers are a staple snack food, but many varieties are made primarily from refined white flour, offering little fiber or nutritional value. The lack of fiber means that these carbohydrates are rapidly digested, which can cause quick spikes in blood sugar levels. Popular brands such as Ritz and Saltines are examples of crackers with high glycemic index values, meaning they are absorbed quickly into the bloodstream. According to the Harvard T.H. Chan School of Public Health, frequent consumption of refined grain snacks is linked to greater difficulty in managing blood glucose and an increased risk of chronic disease.

For a healthier snack, look for whole grain or seed-based crackers that offer more fiber and nutrients. Pairing crackers with a source of protein, such as low-fat cheese, hummus, or nut butter, can help slow down carbohydrate absorption and support stable blood sugar levels. When shopping, check the ingredients list for whole grains as the first ingredient and aim for options with at least 2-3 grams of fiber per serving. Small changes like these can make snacking both satisfying and healthier for those mindful of their blood sugar.

14. Ice Cream

Ice cream is a classic dessert enjoyed by many, but its high sugar and saturated fat content can significantly impact blood sugar levels. A typical serving of regular ice cream (about half a cup) contains around 14-20 grams of sugar and 7-10 grams of fat, with many people consuming much larger portions in a single sitting. The combination of rapidly absorbed sugar and fat slows digestion only slightly, still allowing for a notable spike in blood glucose. According to the Centers for Disease Control and Prevention (CDC), frequent consumption of sugary desserts like ice cream can contribute to poor blood sugar control and increased risk of type 2 diabetes.

To enjoy ice cream mindfully, opt for smaller portions and limit frequency. Choose varieties with less added sugar, such as those labeled “light” or made with natural sweeteners, and consider using a small bowl to help manage serving size. Alternatives like frozen yogurt, fruit-based sorbets, or homemade “nice cream” made from blended frozen bananas can also satisfy cravings with fewer blood sugar consequences. Being mindful of portion sizes and savoring each bite can make indulgences more satisfying without putting health at risk.

Nut butters, such as peanut and almond butter, are often considered nutritious spreads, but many store-bought varieties contain added sugars. These sweetened nut butters can contribute to unexpected blood sugar spikes, particularly when spread on high-carb foods like white bread or crackers. Brands often add sugar, honey, or syrups to improve flavor and texture, with some products containing up to 3-4 grams of added sugar per tablespoon. According to the U.S. Food and Drug Administration (FDA), these hidden sugars can add up quickly and undermine the health benefits of nut butters.

Natural or unsweetened nut butters, on the other hand, contain only nuts and perhaps a small amount of salt, providing healthy fats, protein, and fiber without the blood sugar impact of added sweeteners. When shopping, check ingredient lists and nutrition labels carefully—choose options with minimal ingredients, ideally just nuts and salt. You can also make your own nut butter at home for full control over what you’re eating. Pair nut butters with whole-grain bread, apple slices, or celery to create a balanced snack that supports stable blood sugar and lasting energy.

16. Canned Fruit in Syrup

Canned fruit is a convenient way to enjoy fruit year-round, but when packed in syrup, it becomes a source of concentrated added sugars. The syrup—whether labeled as “light” or “heavy”—often contains high-fructose corn syrup or cane sugar, which can cause rapid blood sugar spikes when consumed. For example, a half-cup serving of canned peaches in heavy syrup can contain up to 20 grams of added sugar, according to the Centers for Disease Control and Prevention (CDC). These sugars are quickly absorbed and can overwhelm the body’s ability to regulate glucose, especially in those with insulin resistance or diabetes.

Fresh fruit or fruit canned in its own juice or water is a much healthier alternative, offering natural sweetness along with fiber, vitamins, and antioxidants. If only syrup-packed options are available, draining and thoroughly rinsing the fruit under running water can help remove some of the excess sugar. Always check the label for added sugars, and favor options marked “no added sugar” or “packed in 100% juice.” Choosing fruit in its most natural state supports better blood sugar control and overall health.

17. Muffins

Muffins are often marketed as wholesome breakfast or snack options, but their typical ingredients—refined flour and large amounts of added sugar—can make them a source of rapid blood sugar spikes. Many commercially available muffins, especially those from coffee shops or bakeries, are oversized and can contain over 30 grams of sugar and 50 grams of refined carbohydrates per serving. According to the Centers for Disease Control and Prevention (CDC), such high-carb, high-sugar foods are quickly digested and absorbed, causing a surge in blood glucose levels followed by an inevitable energy crash.

Coffee shop muffins, for example, are often closer in nutritional value to cake than to a healthy breakfast. To enjoy muffins without the blood sugar rollercoaster, consider making your own at home using whole grain flour, unsweetened applesauce or mashed banana for sweetness, and adding fiber-rich ingredients like oats, flaxseed, or grated zucchini. Smaller portion sizes and controlling added sugars can make a significant difference. Swapping store-bought muffins for homemade versions not only allows for better ingredient choices, but also helps support steady energy and better blood sugar management throughout the day.

18. Ketchup

Ketchup is a widely used condiment that often contains more sugar than people realize. A single tablespoon of commercial ketchup can contain up to 4 grams of added sugar, largely from high-fructose corn syrup or cane sugar. These hidden sugars can quickly add up, especially when ketchup is used generously on foods like burgers, fries, and sandwiches. According to the U.S. Food and Drug Administration (FDA), many popular condiments, including ketchup and barbecue sauce, are significant sources of added sugars in the American diet.

In real-world use, it’s common for people to pour multiple servings of ketchup onto a single meal, unknowingly increasing their sugar intake and contributing to blood sugar spikes. For those looking to reduce sugar, there are now a variety of lower-sugar or unsweetened ketchup options available at most grocery stores. Reading labels for terms like “no added sugar” or “unsweetened” can help make healthier choices. Alternatively, using other condiments such as mustard, salsa, or homemade tomato relish can add flavor with little to no sugar, supporting better blood sugar control without sacrificing taste.

19. Sweetened Coffee Drinks

Sweetened coffee drinks have become increasingly popular, but their added syrups and flavorings can dramatically increase sugar intake and cause significant blood sugar spikes. Specialty beverages like flavored lattes, frappuccinos, and iced coffees often contain multiple pumps of syrup, whipped cream, and even sweetened milk, bringing total sugar content to 30 grams or more per serving. The Centers for Disease Control and Prevention (CDC) notes that sugar-sweetened beverages, including coffee drinks, are a major source of added sugars in the diet and can negatively impact blood glucose management.

In contrast, black coffee contains virtually no carbohydrates or calories and does not raise blood sugar when consumed plain. For those who enjoy coffee drinks, mindful ordering is key to reducing sugar intake. Request fewer pumps of syrup, opt for sugar-free flavors, choose nonfat or unsweetened milk alternatives, and skip the whipped cream. Many coffee shops also offer smaller cup sizes and “light” versions of popular drinks. Reading nutritional information and asking for drinks to be made with less or no added sugar can help you enjoy your coffee without the unwanted blood sugar effects.

20. Fruit Juice

Fruit juice is often viewed as a healthy beverage, but its natural and, at times, added sugars make it a significant source of rapid blood sugar spikes. Even 100% fruit juice contains concentrated fructose and glucose, and many commercial juices include extra sweeteners to enhance flavor. An eight-ounce glass of orange juice, for example, can contain over 20 grams of sugar, which is similar to the sugar content of some sodas. The Harvard T.H. Chan School of Public Health highlights that juice lacks the fiber found in whole fruit, making its sugars more quickly absorbed and less satiating.

In contrast, whole fruits provide fiber, vitamins, and antioxidants, which slow sugar absorption and help support steady blood sugar levels. Swapping juice for whole fruit is a simple way to reduce glucose spikes while still enjoying sweet flavors and important nutrients. If you choose to drink juice, keep portions small—ideally 4 ounces or less at a time—and look for “100% juice” with no added sugars. Diluting juice with water or using it as a flavoring for sparkling water are other strategies for enjoying the taste while minimizing blood sugar impact.

21. Bagels

21. Bagels

Bagels are a breakfast favorite for many, but their dense, refined flour composition packs a substantial carbohydrate load. A single large bagel can contain 50 grams or more of carbohydrates—equivalent to several slices of white bread. Because bagels are often made from refined white flour, they digest quickly and cause a rapid surge in blood sugar levels, especially when eaten without protein or fiber-rich toppings. The Centers for Disease Control and Prevention (CDC) warns that high-carb foods made from refined grains can complicate blood sugar management for those at risk of diabetes or already diagnosed.

In comparison, choosing smaller bread options such as whole wheat English muffins or thin sandwich rounds can help reduce carbohydrate intake and blunt the blood sugar response. For those who love bagels, moderation is key: opt for mini bagels, share with a friend, or eat only half at a time. Pairing bagels with protein-rich spreads like nut butter or low-fat cream cheese and adding fiber with vegetables can further slow carbohydrate absorption. Being mindful of both portion size and ingredients helps make bagels an occasional treat rather than a daily blood sugar challenge.

Fruit-flavored snacks, such as gummies and fruit roll-ups, are a popular choice for children’s lunchboxes and as quick snacks for adults. However, these products are often loaded with added sugars and contain little to no actual fruit. Despite being marketed as “fruit snacks,” they typically derive their sweetness from corn syrup, cane sugar, or fruit juice concentrates. A single pouch can contain upwards of 10-15 grams of added sugar—nearly as much as many candy bars. According to the Centers for Disease Control and Prevention (CDC), snacks high in added sugars can contribute to poor blood sugar control and unhealthy dietary patterns in both children and adults.

When compared to packing whole fruit, fruit-flavored snacks provide none of the fiber, vitamins, or minerals naturally found in real fruit. For healthier lunchbox choices, opt for fresh fruit or unsweetened dried fruit in moderation. Always read nutrition labels to check for added sugars and look for products with “fruit” as the first ingredient and minimal additional sweeteners. Making these swaps helps support stable blood sugar levels and offers greater nutritional value with every snack.

Milkshakes are a beloved treat, but their combination of ice cream, flavored syrups, and whole milk results in a beverage loaded with sugar and calories. A typical fast food milkshake can contain more than 50 grams of sugar and upwards of 500 calories in a single serving. For instance, a medium vanilla milkshake from a popular fast food chain often contains around 60 grams of sugar—well beyond the daily recommended limit. Such high sugar content is rapidly absorbed, sending blood glucose soaring and placing extra strain on the body’s insulin response. The U.S. Food and Drug Administration (FDA) highlights that beverages like milkshakes are a significant source of added sugars in the modern diet.

To enjoy the flavor of milkshakes without the blood sugar crash, try healthier alternatives such as homemade smoothies made with frozen fruit, low-fat milk, and no added sugar. Blending frozen bananas with unsweetened almond milk and a dash of cocoa powder can create a creamy, milkshake-like treat with much less sugar. Always be mindful of portion sizes and ingredients to keep your sweet treats more balanced and blood sugar-friendly.

Pancakes are a classic breakfast favorite, but their traditional preparation with refined white flour and generous amounts of syrup can result in a substantial blood sugar spike. The simple carbohydrates in refined flour digest quickly, while popular pancake syrups often contain high-fructose corn syrup or cane sugar—sometimes adding 12-20 grams of sugar per serving. When pancakes and syrup are combined, a single breakfast can easily exceed daily recommended sugar and carbohydrate limits. The Centers for Disease Control and Prevention (CDC) notes that such carb-heavy breakfasts are associated with difficulty in blood sugar management and increased risk of insulin resistance.

By comparison, breakfasts that focus on whole grains, lean protein, and fresh fruit typically result in steadier energy and more stable blood sugar levels. For a healthier twist on pancakes, use whole grain or oat flour, and top with fiber-rich berries, sliced bananas, or a dollop of plain yogurt instead of syrup. If you do use syrup, opt for a small amount of pure maple syrup and measure your serving. Making these swaps can help you enjoy pancakes while supporting better metabolic health and reducing the risk of unwanted blood sugar spikes.
