Most whole, unprocessed foods are naturally low in sugar. Fresh meat, fish, eggs, non-starchy vegetables, nuts, and many legumes all contain little to no sugar per serving. The challenge isn’t finding low-sugar foods so much as spotting the surprisingly high amounts of sugar hiding in packaged and processed versions of otherwise healthy staples.
The World Health Organization recommends keeping free sugars (the kind added to foods or naturally present in honey, syrups, and fruit juice) below 50 grams per day for someone eating about 2,000 calories. Cutting that to 25 grams offers additional health benefits. Knowing which whole foods are naturally low in sugar, and where sugar sneaks into your diet, makes hitting those numbers much easier.
Meat, Fish, and Eggs
Unprocessed animal proteins are about as close to zero sugar as food gets. A whole egg contains 0.18 grams of sugar. A 3-ounce serving of roasted chicken has 0.26 grams. Fresh fish and raw poultry hover near zero as well.
The picture changes with processed and cured versions. About 85% of packaged cured meats contain at least one added sugar, typically from ingredients like dextrose, honey, or maple flavoring used in the curing process. A 3-ounce serving of cured ham can contain around 4 grams of sugar, which is more than twenty times what you’d find in a plain chicken breast. Deli turkey, even rotisserie-style, carries about 2 grams per ounce. If you’re choosing deli meats, checking the nutrition label is worth the few seconds it takes.
Vegetables With the Least Sugar
Non-starchy vegetables are reliably low in sugar. Leafy greens like spinach, kale, and arugula contain less than 1 gram per cup. Cucumbers, celery, mushrooms, zucchini, bell peppers, broccoli, and cauliflower all stay under 3 to 4 grams per cup. These are foods you can eat in large quantities without meaningfully affecting your sugar intake.
Starchy vegetables like corn, sweet potatoes, and beets carry more sugar, though still far less than processed snacks. The bigger concern for most people isn’t the vegetables themselves but what goes on top of them: dressings, glazes, and sauces that can add several grams of sugar per tablespoon.
Fruits That Stay on the Lower End
Fruit contains natural sugar, so no fruit is truly sugar-free. But the range is wide enough that your choice of fruit matters. Avocados top the list at just 0.7 grams of sugar per whole fruit (technically a fruit, despite how we eat them). Raspberries have 4.4 grams per 100 grams, and strawberries come in at 4.9 grams per 100 grams. Blackberries and cranberries also fall on the low end.
For comparison, a medium banana has about 14 grams of sugar, grapes pack around 16 grams per cup, and mangoes can hit 23 grams per fruit. Berries are consistently the best option if you want fruit with minimal sugar, and their high fiber content slows the absorption of what sugar they do contain.
Legumes and Beans
Beans and lentils are low in sugar and exceptionally high in fiber, which makes them useful for keeping blood sugar stable. A cup of cooked lentils delivers 15.6 grams of fiber. Black beans provide 15 grams of fiber per cup, and navy beans lead the pack at 19.1 grams. The sugar content in all of these stays low, typically 1 to 3 grams per cooked cup.
Chickpeas, kidney beans, pinto beans, and green peas are similarly low-sugar and fiber-rich. The main thing to watch is canned varieties with added sauces. Baked beans in a sweet sauce can contain 12 or more grams of sugar per serving, turning a low-sugar food into a moderate one.
Dairy and Dairy Alternatives
Plain yogurt, whether Greek or regular, is a low-sugar dairy option. The sugars listed on the label of plain unsweetened yogurt come from lactose, a naturally occurring milk sugar, and typically run about 4 to 7 grams per serving. Flavored yogurts generally double that sugar content or more, because manufacturers add sugar, honey, or fruit purees. A flavored yogurt can easily reach 15 to 20 grams per container.
If plain yogurt tastes too tart, adding your own fresh berries gives you sweetness with a fraction of the sugar found in pre-flavored varieties. Cheese is also naturally low in sugar. Hard cheeses like cheddar, parmesan, and Swiss contain less than 1 gram per ounce. Milk itself has about 12 grams of natural sugar per cup, which is worth noting if you drink several glasses a day.
Among non-dairy options, unsweetened almond milk, coconut milk, and soy milk are all low-sugar choices, generally containing 0 to 1 gram per cup. The sweetened versions can jump to 7 or 8 grams, so the word “unsweetened” on the label matters.
Nuts, Seeds, and Healthy Fats
Nuts and seeds are naturally low in sugar. Almonds, walnuts, pecans, macadamia nuts, flaxseeds, chia seeds, and sunflower seeds all contain between 1 and 2 grams of sugar per ounce. Peanuts carry slightly more but remain low, and they add 6.2 grams of fiber per half cup. Olive oil, coconut oil, butter, and avocado oil contain zero sugar.
The exception is flavored or coated nuts. Honey-roasted peanuts, candied pecans, and chocolate-covered almonds can contain 4 to 8 grams of sugar per small serving. Stick with raw, roasted, or lightly salted versions.
Beverages Worth Choosing
Water, plain sparkling water, black coffee, and unsweetened tea all contain zero sugar. Herbal teas are sugar-free as long as nothing has been added. These are the simplest swaps most people can make, because sweetened beverages are one of the largest sources of added sugar in the average diet. A single can of regular soda contains about 39 grams, nearly an entire day’s recommended limit.
If you want something flavored, adding sliced cucumber, lemon, or berries to water gives it taste without meaningful sugar. Unsweetened sparkling waters with natural flavoring also work well as soda replacements.
Where Hidden Sugar Adds Up
The foods that catch most people off guard aren’t desserts. They’re everyday staples that seem healthy or neutral but carry more sugar than expected. A single tablespoon of ketchup contains 4.1 grams of sugar, roughly one teaspoon’s worth. Barbecue sauce is typically worse, often hitting 6 to 8 grams per tablespoon. Salad dressings, teriyaki sauce, and marinara sauce all tend to include added sugar.
Breakfast is another common trap. Granola, flavored oatmeal packets, cereal bars, and most boxed cereals are heavily sweetened. Many granola brands contain 12 to 16 grams of sugar per serving, and servings are often smaller than what people actually pour into a bowl. Bread is more subtle: a single slice of white or wheat bread typically contains 1 to 3 grams of sugar, but it adds up across sandwiches and toast throughout the day.
Over half of packaged protein foods in a major grocery store analysis contained at least one added sugar ingredient. The total amounts were small on average (about 3.2 grams per 100 grams for products with added sugar), but they add to your daily total in ways that aren’t obvious unless you read labels.
Reading Labels Effectively
Since 2020, U.S. nutrition labels must list “Added Sugars” separately from total sugars. This distinction is useful because it lets you see the difference between the lactose naturally present in yogurt and the sugar the manufacturer stirred in. A food labeled “sugar free” must contain less than 0.5 grams of sugar per serving, per FDA rules. There is no official FDA definition for “low sugar,” so that phrase on a package doesn’t carry a regulated meaning.
Sugar also appears under dozens of names on ingredient lists: high-fructose corn syrup, cane juice, dextrose, maltose, agave nectar, rice syrup, and barley malt, among others. If any of these appear in the first three or four ingredients, sugar is a major component of that product. The closer to the end of the list, the less sugar has been added.
