What is White kidney bean?

White kidney bean, also known as kidney bean, string bean, knife bean, lentil bean, jade bean, bean, etc., is a common edible bean in the world, in China's provinces and districts are planted. White kidney bean is not only rich in nutrition, but also has high value of medicine and health care. White kidney beans are soaked in water, extracted, filtered, concentrated and spray dried to obtain a product called white kidney bean extract. Its active ingredient is an α -amylase inhibitor, which is actually a glycosylated protein with a molecular weight of about 30 kDa.

The α -starch inhibitor in white kidney bean can bind to the active site of α -amylase, thus blocking the binding of starch and α -amylase, inhibiting starch metabolism, blocking the digestion and decomposition of carbohydrates, slowing down the absorption rate of glucose, and discharging excess carbohydrates from the body to prevent the accumulation of fat. Therefore, with ordinary weight loss drugs, with no drainage, no rebound, no diet, no injury and other advantages, is an ideal weight loss "artifact".

The main manufacturers of white kidney bean are mainly concentrated in North America, Europe, India and other places, and it has been applied in various food directions such as dietary supplement, meal beverage, tablet candy, function powder, function powder package and so on.


White kidney bean extract has become popular all over the world in the past few years, especially in North America, Europe and other places. More than 600 news media have reported on it, and some doctors, nutritionists and professors are also recommending its use. Moreover, large food giants such as Unilever and Nestle have developed a series of weight loss using white kidney bean extract Slimming products, while the domestic market at present is still mainly weight loss products application of l-carnitine has side effects, such as raw materials research and development Thus, according to some common weight loss in the market Thin body fall blood sugar of the raw materials, the use of white kidney bean extract and resistance dextrin (dietary fibre, increase satiety, can reduce the heat energy intake) low poly (prebiotics) inulin fructose Mulberry leaf extract (1 - deoxidization wild tajiri drug can inhibit the disaccharides hydrolysis enzyme activity, thereby inhibition of small intestine to absorb disaccharide, slow down the decomposition and absorption of carbohydrates) rich chromium yeast (influence the synthesis and degradation of fat and cholesterol in the liver, reduce serum triglyceride and total cholesterol), such as food raw material combination development of solid beverage tabletting candy biscuits A range of slimming products, such as energy bars, have allowed obese people to return to normal weight and women who love beauty to have the ideal figure.

What is α -amylase inhibitors?

"α -amylase inhibitors", commonly known as "starch blockers", are a class of natural substances that can block the decomposition and absorption of starch in food. They specifically form inhibitory complexes with α -amylase in the oral cavity and intestinal tract to block the decomposition and absorption of starch.

Blocking agent containing starch super vitality of alpha amylase inhibitors, inhibit alpha amylase activity in the human body, and blocking the decomposition of starch, make human body content in the food intake of starch can not be converted into glucose, blocking the body to absorb the heat generated by the starchy foods, thus effectively control postprandial blood glucose control weight regulating blood lipid.


Kidney beans are mainly composed of carbs and fiber but also serve as a good source of protein.

The nutrition facts for 3.5 ounces (100 grams) of boiled kidney beans are:

Calories: 127

Water: 67%

Protein: 8.7 grams

Carbs: 22.8 grams

Sugar: 0.3 grams

Fiber: 6.4 grams

Fat: 0.5 grams

Kidney beans are rich in protein.

Only 3.5 ounces (100 grams) of boiled kidney beans boast almost 9 grams of protein, accounting for 27% of the total calorie content. Although the nutritional quality of bean protein is generally lower than that of animal protein, beans are an affordable alternative for many people. In fact, beans are one the richest plant-based sources of protein, sometimes referred to as “poor man’s meat” . The most widely studied protein in kidney beans is phaseolin, which may cause allergic reactions in some people.

Kidney beans also contain other proteins like lectins and protease inhibitors.



Kidney beans are mainly composed of starchy carbs, which account for approximately 72% of the total calorie content. Starch is predominantly made up of long chains of glucose in the form of amylose and amylopectin. Beans have a relatively high proportion of amylose (30–40%) compared to most other dietary sources of starch. Amylose is not as digestible as amylopectin.

For this reason, bean starch is a slow-release carb. Its digestion takes longer, and it causes a lower and more gradual rise in blood sugar than other starches, making kidney beans particularly beneficial for people with type 2 diabetes.


Kidney beans rank very low on the glycemic index (GI), which is a measure of how foods affect your rise in blood sugar after a meal. In fact, bean starch has a more beneficial effect on blood sugar balance than many other high-carb foods.



Kidney beans are high in fiber.

They contain substantial amounts of resistant starch, which may play a role in weight management. Kidney beans also provide insoluble fibers known as alpha-galactosides, which may cause diarrhea and flatulence in some people. Both resistant starch and alpha-galactosides function as prebiotics. Prebiotics move through your digestive tract until they reach your colon, where they’re fermented by beneficial bacteria. The fermentation of these healthy fibers results in the formation of short-chain fatty acids (SCFAs), such as butyrate, acetate, and propionate, which may improve colon health and reduce your risk of colon cancer.


Vitamins and minerals

Kidney beans are rich in various vitamins and minerals, including:

Molybdenum. Beans are high in molybdenum, a trace element mainly found in seeds, grains, and legumes.

Folate. Also known as folic acid or vitamin B9, folate is considered particularly important during pregnancy.

Iron. This essential mineral has many important functions in your body. Iron may be poorly absorbed from beans due to their phytate content.

Copper. This antioxidant trace element is often low in the Western diet. Aside from beans, the best dietary sources of copper are organ meats, seafood, and nuts.

Manganese. This compound is present in most foods, especially in whole grains, legumes, fruits, and vegetables.

Potassium. This essential nutrient may have beneficial effects on heart health.

Vitamin K1. Also known as phylloquinone, vitamin K1 is important for blood coagulation.



Weight loss

Excess weight gain and obesity are major health problems, associated with an increased risk of various chronic diseases.

Several observational studies link bean consumption to a lower risk of excess weight gain and obesity. A 2-month study in 30 obese adults on a weight loss diet showed that eating beans and other legumes 4 times per week led to greater weight loss than a bean-free diet. A recent review of 11 studies also found some supporting evidence but was unable to draw a firm conclusion.

Various mechanisms may contribute to the beneficial effects of beans on weight loss. These include fibers, proteins, and antinutrients. Among the most widely studied antinutrients in raw kidney beans are starch blockers, a class of proteins that impair or delay the digestion and absorption of carbs (starch) from your digestive tract. Starch blockers, extracted from white kidney beans, demonstrate some potential as a weight loss supplement. However, boiling for 10 minutes completely inactivates starch blockers, eliminating their effect in fully cooked beans. Even so, cooked kidney beans offer a number of weight-loss-friendly compounds, making them an excellent addition to an effective weight loss diet.


Improved blood sugar control

Over time, high blood sugar may increase your risk of many chronic illnesses, such as heart disease. Thus, moderating your rise in blood sugar after meals is considered beneficial for health. Being rich in protein, fiber, and slow-release carbs, kidney beans are very effective at maintaining healthy levels of blood sugar. They have a low GI score, which means that your rise in blood sugar after eating them is low and more gradual. In fact, beans are better at controlling blood sugar than most dietary sources of carbs. Several observational studies indicate that eating beans or other low-glycemic foods may reduce your risk of type 2 diabetes. Eating low-glycemic foods may also improve blood sugar control in people who already have type 2 diabetes.

Even if you don’t have this condition, adding beans to your diet may improve blood sugar balance, protect your overall health, and reduce your risk of many chronic diseases.


Colon cancer prevention

Colon cancer is one of the most common types of cancer worldwide. Observational studies link legume intake, including beans, with a reduced risk of colon cancer. This is supported by test-tube and animal studies. Beans contain a variety of nutrients and fibers with potential anticancer effects. Fibers, such as resistant starch and alpha-galactosides, pass undigested down to your colon, where they’re fermented by friendly bacteria, resulting in the formation of SCFAs. SCFAs like butyrate may improve colon health and lower your risk of colon cancer.
