Each medium russet potato supplies 36 grams of net carbs -- the amount of carbs you actually digest -- while a medium sweet potato has 22 grams. A slice of French or sourdough bread contains 35 grams of net carbs, and a serving of fast-food french fries supplies 45 grams of net carbs. If you're on a restrictive low-carb diet, you may be limited to just 20 grams of net carbs per day.
That excludes virtually any food rich in complex carbohydrates, as a single serving of any of the previously mentioned foods contains more than your daily limit. Generally, you'll get your 20 grams of carbs from veggies -- like leafy greens, leeks, pickles and asparagus -- plus low-sugar fruits like rhubarb. You aren't allowed potatoes, sweet potatoes or any grains or grain products, like bread. You're also restricted from eating higher-protein sources of carbs, like beans and lentils, since these foods still pack in a significant number of carbohydrates.
If you're on a more permissive diet, you may have enough "room" in your carb budget for complex carb-containing foods. Updated September 19, Treatment of diabetes: The diabetic diet.

Frequently Asked Questions How many carbs should someone eat per day if they do not have diabetes? What is considered a low-carb diet? Overdoing simple carbs can also pack on pounds, according to a review published in August in the journal Food and Nutrition Research. The authors looked at 50 studies on diet and weight gain and found that, on average, the more simple carbs a person ate, the more weight they tended to gain.
According to the Harvard T. Chan School of Public Health , top dietary sources of complex carbs include:. Simple carbs are found in fruit and dairy products, as well as highly processed or refined foods that have been stripped of fiber, including:. Not at all. It just that those foods should be the exceptions instead of your everyday carbohydrate selections, Meyerowitz says. At the same time, you should avoid overloading on complex carbohydrates or making them your primary source of calories.

In other words, as with many good things, moderation is the key to maintaining a strong and healthy body. This was borne out in another study, published August 16, , in The Lancet , which found that the average life expectancy of moderate-carb eaters someone who got 50 to 55 percent of their calories from carbs was four years longer than low-carb eaters those who got less than 40 percent of their calories from carbs.
Moderate-carb eaters also lived one year longer than the average high-carb eater. By subscribing you agree to the Terms of Use and Privacy Policy. Health Topics.
