Onions are a household vegetable beloved for their simplicity, affordability, and delicious taste. Yet their greatest benefit lies in supporting cardiovascular health. Today, let's explore how onions can enhance your heart and brain health.Purple Onions with Peanuts: Protect Against Cardiovascular Issues
The active compounds in onions act as vasodilators, playing a significant role in preventing and treating hypertension, arteriosclerosis, hyperlipidemia, and coronary heart disease. Purple onions are particularly superior to other onion varieties in this regard.
The unsaturated fatty acids, vitamin E, and zinc in peanuts are crucial for softening blood vessels, fighting oxidation, and boosting immunity. Paired with onions, they form an unbeatable dietary choice for protecting cardiovascular health.
Ingredients: Red onion, peanuts, aged vinegar, savory soy sauce, sugar, chicken bouillon.
Method: Soak peanuts in 40°C–50°C warm water for 3–5 hours, then rinse and set aside. Cut onion into diamond-shaped pieces. Toss onion and peanuts with aged vinegar, savory soy sauce, sugar, and chicken bouillon powder. Serve after 10 minutes. This dish is especially suitable for individuals with hyperlipidemia, hypertension, arteriosclerosis, coronary heart disease, diabetes, or suboptimal health.
2. Onion with Pumpkin: Lowers Blood Sugar and Cholesterol, Protects Gonads
Pumpkin contains fructose that inhibits glucose absorption and binds to excess cholesterol in the body, preventing high cholesterol levels and promoting insulin secretion. Its main components include vitamins A and B complex, along with trace elements cobalt and zinc, all beneficial for health.It also contains phytochemicals like beta-carotene, mannitol, and pectin. The beta-carotene in pumpkin helps prevent prostate enlargement.
Ingredients: 100g pumpkin, 1 slice cheese, 15g bacon, 50g onion, 20g cucumber, a pinch of black pepper.
Method: Wash the pumpkin and cut into long strips. Clean the onion and chop finely. Dice the bacon (fat to lean meat ratio 1:2). Sauté the bacon and onion, then mix with shredded cheese. Place the mixture on the pumpkin strips, sprinkle with black pepper, and top with cucumber slices. Steam the pumpkin in an electric rice cooker until tender.
3. Onion with Eggs: Relieves Constipation, Protects the Intestines
The sulfur compounds in onions combine with proteins or intestinal bacteria in the large intestine to form hydrogen sulfide, which promotes intestinal peristalsis. Eggs effectively enhance this effect of onions.
Ingredients: Onion, fresh shrimp, crab sticks, straw mushrooms, 3 eggs;salt, MSG, pepper, cooking wine, clear broth (or water).
Method: Beat eggs with salt, MSG, pepper, and clear broth until well combined. Steam until set, then set aside. Wash onion, straw mushrooms, and shrimp. Finely chop onion and slice mushrooms.In a separate pot, blanch the sliced straw mushrooms, shrimp, and crab sticks until cooked. Drain and place them on top of the steamed egg custard along with the chopped onion. In a saucepan, bring the clear broth to a boil. Season with salt, MSG, pepper, and cooking wine. Pour the hot broth over the egg custard prepared in step 2.
4. Onion with Beef: Tonifies the Middle Burner, Strengthens Tendons and Bones
Beef is rich in protein and amino acids. Its composition is closer to human nutritional needs than pork, enhancing the body's disease resistance. It is particularly suitable for growth and development, as well as for replenishing blood loss and repairing tissues during post-surgery or convalescence.
Traditional Chinese dietary therapy holds that beef fortifies the middle energizer, nourishes the spleen and stomach, strengthens tendons and bones, transforms phlegm, calms wind, and alleviates thirst and excessive salivation. It is recommended for those with sinking middle qi, shortness of breath, weakness, aching joints, anemia, chronic illness, or jaundice with dizziness.
Ingredients: 120g sliced onion, 120g sliced jicama, 15g wood ear mushrooms, several slices of ginger, 1 teaspoon minced garlic, 150g beef.Thinly slice beef and marinate with seasoning for 10 minutes. Heat 2 tablespoons oil, stir-fry ginger, add beef and minced garlic until beef is nearly cooked. Add seasoning, onions, wood ear mushrooms, and jicama, stir-fry until combined. Thicken with cornstarch slurry and serve.
What are the benefits of onions?
1. Preventing and treating heart disease: Half a cup of onion juice daily
Onions are a vasodilator food that softens blood vessels and promotes the excretion of sodium salts and other substances that raise blood pressure. Thus, they regulate blood lipids, lower blood pressure, and prevent blood clots, effectively preventing and aiding in the treatment of heart disease.
Eating half an onion raw daily, or drinking an equivalent amount of onion juice, can increase HDL cholesterol levels by approximately 30% in heart disease patients. (HDL: cholesterol that helps prevent atherosclerosis, known as "good" cholesterol.)
2. Calcium Supplementation: One Plate of Stir-Fried Onions Daily
Onions contain calcium and volatile sulfur compounds that prevent calcium loss. Simply supplementing calcium without preventing its loss is ineffective. Calcium loss is a primary symptom of osteoporosis. Regular onion consumption increases bone density and prevents osteoporosis.
Therefore, regular onion consumption aids calcium absorption and helps prevent osteoporosis. Pairing onions with meat or beans further enhances calcium benefits. When eating onions for calcium, avoid overcooking them.
3. Asthma: Daily raw onion salad
Onions contain at least three natural anti-inflammatory compounds that help prevent and manage asthma. This is because their active ingredients inhibit histamine activity, which triggers allergic asthma symptoms.
Studies show onions can reduce asthma attack frequency by about half.
4. Lowering Blood Sugar: 30g of Vinegar-Soaked Onions
Modern medicine confirms onions offer equal blood-sugar-lowering effects whether eaten raw or cooked. This is due to a compound similar to the common oral hypoglycemic drug metformin, which effectively stimulates insulin synthesis and release.
For blood sugar control, try this recipe: Peel and wash 500g of onions, slice thinly, and microwave for 2-3 minutes. Remove, add 600ml of vinegar, then refrigerate overnight. Consume once daily, preferably no more than 30g per serving. This method also aids weight loss.
5. Cold Relief & Anti-Inflammation: Drink Hot Onion Soup
When plant-based antibacterial compounds in onions are expelled through the respiratory tract, urinary tract, and sweat glands, they stimulate secretion along these pathways. This action promotes expectoration, diuresis, sweating, cold prevention, and antibacterial effects—particularly beneficial for elderly individuals with weakened immunity.
When suffering from a cold, drinking hot miso soup with onions can quickly induce sweating and reduce fever. For nasal congestion, place a slice of onion against the nostrils; its pungent aroma will instantly clear the nasal passages.
6. Gout: Onions Soaked in Red Wine
Peel and slice onions, soak them in red wine, and refrigerate for one week. Consuming both the wine and onions provides significant relief for gout.
Precautions for onion consumption
1. Avoid excessive onion intake
Onions produce volatile gases that may cause bloating and excessive flatulence when consumed in large quantities, leading to discomfort.
2. Onions are particularly suitable for the following groups:
While generally safe for most people, onions are especially beneficial for those with diabetes, cancer, acute/chronic enteritis, dysentery, hypertension, hyperlipidemia, cardiovascular diseases like atherosclerosis, and indigestion. However, certain individuals should exercise caution.
3. Individuals with the following conditions should avoid onions
Those with itchy skin conditions, eye diseases, stomach ailments, or inflammation of the stomach and lungs should limit onion intake. Patients with feverish illnesses should exercise caution, as onions possess a pungent, warming nature. When suffering from eye diseases or ocular congestion, avoid cutting onions, as their pungent aroma can irritate the eyes.
4. Avoid prolonged cooking of onions
The sulfuric acid in onions is an oily volatile liquid that easily evaporates during extended cooking, thereby losing its blood sugar-lowering efficacy.

5. Avoid combining onions with honey
Honey has heat-clearing properties. Onions contain various bioactive compounds that react with organic acids and enzymes in honey, producing toxic substances that irritate the gastrointestinal tract, causing bloating and diarrhea.
1. Peel the onion, trim off the top and root end, then submerge it in water for 15 minutes. After soaking, it will be much easier to slice!
2. When stir-frying onions, they tend to soften and stick together. To prevent this, toss the sliced onions with a small amount of flour beforehand. This will also give them a golden color, crisp texture, and better taste.
Don't miss out on such a wonderful food! And don't forget to tell your friends and family: starting today, eat one onion daily to cleanse your blood vessels and prevent disease. Be sure to stick with it!
Conclusion: Onions are a vasodilator food that softens blood vessels and promotes the excretion of substances like sodium salts that raise blood pressure. Thus, they regulate blood lipids, lower blood pressure, and prevent blood clots, making them excellent for preventing and aiding in the treatment of heart disease.
