Generally speaking, garlic and coffee can be consumed together, but intake should be moderated. Detailed analysis is as follows:

Garlic contains allicin, vitamin B, and minerals, and has antibacterial properties; coffee is rich in caffeine and chlorogenic acid, which can refresh the mind and relieve fatigue. When consumed together, their components do not conflict, and moderate consumption can provide different nutrients while satisfying taste preferences. Generally, when consumed in moderation, combining garlic and coffee will not cause significant discomfort.

However, individuals with weak gastrointestinal function or those suffering from gastric ulcers may experience stomach pain, acid reflux, and other symptoms due to the irritancy of garlic and the caffeine in coffee stimulating the gastric mucosa. People allergic to garlic or caffeine may experience allergic reactions such as rashes and palpitations after consumption, so they should avoid consuming both together. Additionally, since coffee has a diuretic effect, attention should be paid to hydration when consumed with garlic to avoid excessive caffeine intake causing nervous excitement.

Furthermore, in daily diets, it is important to maintain balanced nutrition and diversified food intake, avoiding excessive consumption of any single food item to promote overall health.
