“Start by eating 2 cloves a day” — is that a good health habit?
If this headline is referring to raw garlic, eating around 1–2 cloves a day is generally tolerated by many healthy adults, but it is not a proven cure or prevention for a long list of diseases. Garlic has been studied for cholesterol and blood pressure, with possible small benefits, but the evidence doesn’t justify treating it as a medicine.
What garlic may actually do
- 🩸 Cholesterol: Garlic supplements may modestly lower total and LDL cholesterol in people with elevated levels.
- ❤️ Blood pressure: Some evidence suggests a small reduction in people with hypertension.
- 🦠 Colds: Evidence is currently insufficient to conclude that garlic reliably prevents or treats the common cold.
- 🍽️ General nutrition: Garlic is a flavorful, low-calorie food containing compounds such as allicin and can easily be part of a healthy diet.
⚠️ Raw garlic isn’t for everyone
Two cloves can cause heartburn, stomach pain, gas, nausea and bad breath, particularly when eaten raw.
Garlic can also increase bleeding risk, which matters if you’re taking anticoagulants or aspirin, or if you’re preparing for surgery. It may also interact with some medicines.
