Are Kidney Beans Good for Sugar Cravings?
Partly: kidney beans may help with sugar cravings when eaten as part of a balanced meal because their fiber and protein can support fullness, but they have not been proven to reduce sugar cravings specifically.
A small trial found that a meal containing kidney beans increased fullness in older adults, but it did not establish an effect on cravings for sweets. Use fully cooked kidney beans rather than raw or undercooked ones, and see the best foods for sugar cravings for other meal ideas.
Can kidney beans help with sugar cravings?
Kidney beans may be useful if your desire for something sweet tends to appear when you are hungry between meals. Adding them to a satisfying meal could help you feel full for longer, making it easier to wait until your next meal or snack.
That is different from showing that kidney beans directly reduce a craving for sugar. Cravings can also be influenced by habits, emotions, sleep and the availability of appealing foods. Kidney beans may help with the hunger part, but they will not necessarily address every reason you want something sweet.
How might kidney beans work?
Kidney beans contain fiber and protein, both of which can contribute to fullness. Their fiber also slows digestion of the meal, which can affect how quickly carbohydrates are absorbed. A steadier response after eating may be useful for some people, although it does not guarantee that a sugar craving will go away.
The rest of the meal matters too. Kidney beans in a meal with vegetables and a grain can make that meal more substantial than eating the vegetables alone. Choose an amount that fits your appetite rather than treating kidney beans as a supplement or a required serving.

What does the evidence say?
In a 2025 randomized crossover trial in 35 older adults, participants ate breakfast tortillas containing red kidney beans, black beans or beef on separate occasions. The kidney bean meal increased fullness, with a satiety effect that was not significantly different from the beef meal. The trial supports the idea that kidney beans can be satisfying, but it does not establish that they reduce sugar cravings specifically.
A 2025 review of white kidney beans discussed potential effects on starch digestion, blood sugar after meals, appetite and fullness. It also noted differences between studies and limited long-term safety information. Some of the evidence concerns kidney bean extracts and supplements, so its findings cannot simply be applied to a serving of cooked kidney beans.
Overall, evidence for kidney beans and fullness is more relevant than evidence for kidney beans and sugar cravings. Direct proof of a craving-specific benefit remains limited.
How can you use kidney beans for sugar cravings?
Add cooked kidney beans to a meal you already enjoy, such as a grain bowl, salad or tortilla with vegetables. Eating them as part of a meal is a practical way to make use of their fiber and protein; there is no established amount proven to prevent sugar cravings.
If you do not usually eat kidney beans, start with a few spoonfuls and increase gradually as tolerated. A sudden increase in fiber can cause gas or bloating. Notice whether the meal keeps you comfortably full and whether your desire for sweets changes; either result is useful information, not proof of a medical problem.
Canned kidney beans are convenient because they are already cooked. Drain and rinse them if you prefer, and choose a lower-sodium option if you need to limit sodium. Refrigerate leftovers promptly.
If preparing dried kidney beans, soak them as directed, discard the soaking water, then boil them vigorously in fresh water and simmer until tender, following reliable package directions. Do not rely on a slow cooker alone to make raw kidney beans safe: undercooked kidney beans can cause severe gastrointestinal illness.
Who should be careful with kidney beans?
If you have kidney disease or have been told to limit potassium or phosphorus, ask your clinician or renal dietitian how kidney beans fit your eating plan. If you have a bean allergy, avoid kidney beans unless your clinician advises otherwise.
If you take insulin or another medication that can cause low blood sugar, check your glucose when you have symptoms such as shakiness or sweating and follow your prescribed low-glucose plan. Kidney beans are not a treatment for low blood sugar. If someone is unconscious or cannot swallow safely, call emergency services and do not give them food or drink.
Seek medical care promptly for severe or persistent vomiting or diarrhea, particularly after eating undercooked kidney beans. Talk with a clinician or dietitian if cravings are persistent, distressing or accompanied by other symptoms.
Frequently asked questions
Do kidney beans need to replace dessert?
No. Kidney beans can be part of a satisfying meal without requiring you to avoid dessert or other sweet foods.
Can kidney beans be eaten cold?
Yes. Fully cooked kidney beans, including kidney beans from a can, can be eaten cold.
Do red and white kidney beans have the same effect on cravings?
There is not enough direct evidence to say whether either type reduces sugar cravings or whether one works better than the other.
