The carb count in everyday foods ranges from practically zero (a single egg has just 0.56 grams) to over 44 grams in a cup of cooked white rice. Whether you’re tracking carbs for blood sugar management, weight loss, or general awareness, knowing where carbohydrates hide in common foods makes a real difference in how you plan meals. Here’s a practical breakdown of the most-searched foods.
Banana
A medium ripe banana contains about 28 grams of carbohydrates, including 15 grams of naturally occurring sugar and 3 grams of fiber. That’s roughly the same carb load as two slices of white bread.
Ripeness matters more than most people realize. A green or slightly underripe banana contains a higher proportion of resistant starch, a type of carbohydrate your small intestine can’t break down. Because it digests slowly, it causes a smaller blood sugar spike. The glycemic index of a slightly underripe banana is 42, compared to 51 for a fully ripe one. As a banana ripens and those brown spots appear, that resistant starch converts into simple sugars, which is why ripe bananas taste sweeter even though the total carb count stays roughly the same.
Slice of White Bread
One standard slice of commercially prepared white bread has about 13 grams of carbohydrates. Most of those carbs come from refined flour, meaning they digest quickly and raise blood sugar faster than whole-grain alternatives. Two slices for a sandwich puts you at roughly 26 grams before you add anything between them.
Baked Potato
A medium baked potato (roughly 2.25 to 3.25 inches in diameter) with the skin on contains about 36.5 grams of carbohydrates and 3.6 grams of fiber. That fiber count goes down if you scoop the flesh out and skip the skin. Potatoes are one of the most carb-dense vegetables, landing in a completely different category than leafy greens or broccoli, which typically have 5 grams or less per serving.
Cup of Cooked White Rice
One cup of cooked long-grain white rice packs about 44.5 grams of carbohydrates, making it one of the highest-carb staples in a typical meal. That’s a single cup, and most restaurant portions are closer to two cups. If rice is a regular part of your diet and you’re watching carbs, measuring with an actual measuring cup instead of eyeballing it can prevent you from unknowingly doubling your intake.
Glass of Milk
An 8-ounce cup of whole milk contains about 12 grams of carbohydrates. All of that comes from lactose, a naturally occurring sugar, not added sugar. Skim and low-fat milk have similar carb counts since removing fat doesn’t change the lactose content. If you’re lactose intolerant and use lactose-free milk, the carb count stays the same, but the lactose has been pre-broken down into simpler sugars that are easier to digest.
Beer
A standard 12-ounce beer typically falls between 10 and 13 grams of carbohydrates. Budweiser and Dos Equis Lager both come in at about 11 grams per 12-ounce serving. Light beers cut that significantly: Coors Light drops to around 5 grams per 12-ounce serving. If you’re having two or three beers over an evening, the carbs from regular lagers can add up to the equivalent of eating a couple slices of bread you might not have accounted for.
Egg
A large hard-boiled egg contains just 0.56 grams of carbohydrates. For practical purposes, that’s essentially zero. This makes eggs one of the most carb-friendly protein sources available, which is why they show up in nearly every low-carb and ketogenic meal plan. Cooking method doesn’t change the carb count, but what you cook them in can: butter adds no carbs, but ketchup or toast on the side obviously will.
Avocado
A whole avocado has about 17 grams of total carbohydrates, but 14 of those grams come from dietary fiber. That gives it roughly 3 grams of net carbs for an entire fruit, which is why avocados are a staple in low-carb diets despite their relatively high total carb number on a nutrition label.
Total Carbs vs. Net Carbs
The number on a nutrition label is total carbohydrates, which includes fiber and sugar alcohols. Your body doesn’t absorb fiber the same way it absorbs other carbs, so many people subtract fiber from the total to get “net carbs,” the amount that actually affects your blood sugar. The avocado example above illustrates why this distinction matters: 17 grams of total carbs sounds moderate, but 3 grams of net carbs is very low.
Sugar alcohols, found in many sugar-free and low-carb packaged foods, are partially absorbed. The standard approach recommended by the UCSF Diabetes Teaching Center is to subtract half the sugar alcohol grams from total carbohydrates. So if a protein bar lists 29 grams of total carbs and 18 grams of sugar alcohols, you’d divide the sugar alcohols in half (9 grams) and subtract that from the total, giving you 20 grams of effective carbohydrates.
