2026-05-18

Basic nutrients per 100 grams (cucumber)

Total calories: 15 kcal

Carbohydrates: 2.90 grams

Protein: 0.80 grams

Fat: 0.20 grams

Dietary fiber: 0.50g

Precautions for consumption

People with weak spleen and stomach, abdominal pain and diarrhea, or cold cough should eat less cucumber, because cucumber is cooling in nature and can easily cause abdominal pain and diarrhea in patients with cold stomach.

The principle of fat loss and muscle gain

The glucosides and fructose contained in cucumbers do not participate in normal sugar metabolism, so diabetic patients can use cucumbers to replace starchy foods to satisfy their hunger. Not only will their blood sugar not rise, but it may even decrease.

Cucumbers contain malonic acid, which can inhibit the conversion of carbohydrates into fat. In addition, the fiber in cucumbers helps promote the elimination of putrefactive substances from the intestines and lowers cholesterol, thus contributing to overall health.

Low-calorie combination

Raw cucumbers can help with weight loss, while wood ear mushrooms can strengthen the body and replenish blood. Eating them together can balance nutrition.

Cucumbers are best eaten with tofu, as they complement each other nutritionally and can have effects such as clearing heat and promoting urination, detoxifying, reducing inflammation, nourishing the lungs and promoting body fluid production, and moisturizing dryness and soothing the stomach.

Basic nutrients (konjac) per 100 grams

Total calories: 37 kcal

Carbohydrates: 78.00 grams

Protein: 4.60 grams

Fat: 0.10 grams

Dietary fiber: 74.40 grams

Precautions for consumption

Raw konjac is poisonous and must be boiled for more than 3 hours before it can be eaten. Also, the amount consumed at one time should not be too much.

The principle of fat loss and muscle gain

Konjac is a low-calorie food. Its main component, glucomannan, absorbs water and swells, increasing in volume to 30 to 100 times its original size, thus providing a feeling of fullness and making it an ideal food for weight loss. Konjac can slow down glucose absorption, effectively lowering postprandial blood sugar, thereby reducing the burden on the pancreas and keeping the glucose metabolism of diabetic patients in a virtuous cycle. Unlike some hypoglycemic drugs, it does not cause a sudden drop in blood sugar, leading to hypoglycemia.

Low-calorie combination

Konjac is a low-calorie, high-fiber food. When eaten with apples, it can promote intestinal peristalsis, making it an excellent choice for dieters.

Both have the effects of lowering cholesterol and relieving constipation. The combined effect is even better and they are suitable for patients with hyperlipidemia and obese people.

Basic nutrients (carrots) per 100 grams

Total calories: 25 kcal

Carbohydrates: 8.10 grams

Protein: 1.00 g

Fat: 0.20 grams

Dietary fiber: 3.20 grams

Precautions for consumption

Carotene is a fat-soluble substance; only carotene dissolved in oil can be converted into vitamin A in the liver and absorbed by the body. If carrots are eaten raw, 90% of the carotene will be excreted, failing to provide any nutritional benefits. Therefore, carrots should not be eaten raw.

The principle of fat loss and muscle gain

Carrots are very low in calories and very high in vitamins A and C, as well as carotene. These substances can accelerate human metabolism and promote blood circulation.

Low-calorie combination

When eaten together, these two foods can nourish blood, improve eyesight, and protect the liver. They are also effective in treating night blindness caused by vitamin A deficiency.

Carrots + peas: When combined with peas and minced meat, this combination can effectively improve liver function, promote bile secretion, and relieve physical and mental fatigue.

Basic nutrients (potatoes) per 100 grams

Total calories: 76 kcal

Carbohydrates: 17.20 grams

Protein: 2.00 grams

Fat: 0.20 grams

Dietary fiber: 0.70 grams

Precautions for consumption

Potatoes should not be eaten with the skin on, because potato skin contains a substance called solanine, and ingesting too much solanine can lead to poisoning.

The principle of fat loss and muscle gain

Potatoes contain a mucoprotein that can lubricate our digestive and respiratory tracts, prevent cardiovascular disease, and maintain the elasticity and patency of blood vessels.

Potatoes are high in dietary fiber and contain plenty of vitamins and minerals, but they are low in calories and fat, so eating potatoes can also help with weight loss.

Low-calorie combination

Beef has coarse fibers that can sometimes damage the stomach lining. Cooking it with potatoes not only tastes better but also helps protect the stomach lining.

Potatoes + Green Peppers: Eating potatoes with green peppers, which are rich in various vitamins, can complement each other nutritionally and double their effects.
