Eating green foods has a certain auxiliary effect on lowering blood sugar levels because many green foods are rich in dietary fiber, vitamins, and minerals, which help stabilize blood sugar levels.

Here are some common green foods that can help reduce blood sugar:

Leafy Greens:

• Spinach: Rich in dietary fiber and various vitamins, spinach contains spinachine, which promotes insulin secretion and helps lower blood sugar.
• Lettuce: A low-calorie, high-fiber vegetable, lettuce is suitable for diabetics and helps control blood sugar.
• Celery: Celery is not only rich in dietary fiber but also contains various nutrients beneficial to the body, aiding in blood sugar reduction.
• Broccoli: Broccoli is abundant in dietary fiber and vitamins, contributing to stable blood sugar levels.

Gourd Vegetables:

• Cucumber: A low-sugar, low-calorie vegetable, cucumber is suitable for diabetics and aids in blood sugar control.
• Bitter Gourd (Balsam Pear): Bitter gourd contains charantin, which lowers blood sugar, and its insulin-like substance also contributes to reducing blood sugar.

Mushroom Vegetables:

• Mushrooms: Rich in dietary fiber and various trace elements, mushrooms have an auxiliary effect on reducing blood sugar.
• Black Fungus (Wood Ear Mushroom): The polysaccharide in black fungus can lower blood sugar, making it suitable for diabetics.

Other Green Foods:

• Konjac (Konjac Root or Elephant Yam): A low-calorie, high-fiber food, konjac can increase satiety and reduce weight, making it an ideal food for diabetics.
• Onions: Onions contain methylsulfonylmethane (MSM), which promotes insulin secretion and reduces blood sugar.

It's crucial to note that while these green foods have an auxiliary effect on lowering blood sugar, they cannot replace medical treatment. People with elevated blood sugar levels or diabetes should seek medical advice promptly, undergo standardized treatment under a doctor's guidance, and comprehensively control blood sugar through a combination of diet, exercise, and other methods.

Additionally, when consuming these green foods, it's essential to adhere to the principle of moderation to avoid other health issues from overconsumption. Furthermore, cooking methods should prioritize light, low-oil, and low-salt preparations to preserve the nutritional value and health benefits of the food.
