According to Melanie Marcus, a nutritionist in the US, allicin is a sulfur compound released when garlic is crushed. Allicin can help lower LDL cholesterol (bad cholesterol) and reduce blood pressure due to its ability to dilate blood vessels.
Onions contain quercetin, a flavonoid with antioxidant and anti-inflammatory properties, which helps prevent plaque buildup in artery walls.
Meanwhile, gingerol, the compound that gives ginger its characteristic spicy flavor, has the ability to promote blood circulation and reduce triglycerides, a type of fat that is harmful to the heart if present at high levels in the blood.
Notes on usage
Eating raw garlic, onions, and ginger can cause digestive problems for many people. According to Ms. Best, the compounds in these three spices, in their raw and concentrated form, can easily irritate the stomach, leading to heartburn, indigestion, or even negative interactions with blood-thinning medications. Therefore, users need to pay special attention to the dosage and their individual health conditions.
Garlic and ginger have blood-thinning properties, and if taken with anticoagulants like warfarin or aspirin, they may increase the risk of bleeding.
Meanwhile, raw onions and garlic contain substances that can easily cause bloating, gas, and acid reflux, especially in people with sensitive digestive systems. Marcus stated that the combination of raw garlic and onions can cause bad breath. These two foods also contain high levels of FODMAPs, which can worsen symptoms in people with irritable bowel syndrome (IBS).
How to use garlic, onions, and ginger properly.
Experts say that you don't need to eat garlic, onions, and ginger raw to reap their cardiovascular benefits.
A varied, balanced diet that regularly incorporates these ingredients into cooking will yield longer-lasting and safer results.
Trista Best recommends using garlic, onions, and ginger in stir-fries, soups, or sauces. This helps the body absorb nutrients effectively while reducing the risk of digestive irritation.
To optimize nutrient intake, Marcus suggests crushing garlic just before turning off the heat to activate allicin, and you can also add a little ginger to sauces, salads, or tea to take advantage of its natural gingerol content.
Meanwhile, onions can be used to marinate meat, adding both flavor and supporting cardiovascular health.
