1 You might feel bloated
Garlic is high in a type of carbohydrate called fructan. These carbs can also be found in foods like wheat, rye, onions, asparagus, grapefruit, watermelon, black beans, and cashews.
Symptoms of fructan intolerance are very similar to gluten intolerance and include things like bloating, stomach pain, cramps, and excess gas. If you often experience similar gastrointestinal issues after eating garlic, you may want to be careful!

2 You might get heartburn
Gastroesophageal Reflux Disease (GERD), is a very common issue among adults that causes excess acid reflux in the esophagus. This creates a lot of pain, nausea, and heartburn.
If you have GERD or are easily susceptible to heartburn, you may want to be careful with how much garlic you consume. Our bodies have a lower esophageal sphincter (LES), which is a group of muscles that prevents stomach acid from traveling back up to the esophagus. According to Primary Care, garlic can weaken the "tone" of these LES muscles and cause more heartburn, especially for those with GERD or related struggles.

3 You might strengthen your immune system
Garlic can potentially help us strengthen our immune system. According to the Journal of Immunology Research, garlic can improve our immunity by stimulating various types of cells in our body that are directly linked to our immune system function. This report emphasized that more human studies still need to be done on this topic, but the current findings are very promising.

4 You might be able to use it as an anti-fungal
Garlic has been known to contain certain antimicrobial properties, which is basically how you might describe something that kills or destroys a certain organism. "Antimicrobial" is an umbrella term that includes things like antibacterial and anti-fungal.
Garlic may be a helpful anti-fungal agent, but it is recommended as an addition to other types of anti-fungal medicine and shouldn't necessarily be used on its own until more research has been done.

5 You might improve your cognitive function
Some research has found that garlic can have a positive effect on our cognitive function. Aged garlic extract has been known to lower our chances of cognitive decline while helping to improve our memory and retention.
A report found in Experimental and Therapeutic Medicine also found that garlic extract might be able to fight off certain cancers, heart disease, and help prevent dementia because of its unique antioxidant properties.

6 You might lower your blood pressure
Garlic has also been known to have properties that can actually lower our blood pressure levels over time.
In a report published by Dove Medical Press, it was found that one of the main factors in lowering blood pressure with garlic is based on the polysulfides found in their makeup. These polysulfides help to regulate what is known as the "redox signaling pathways" in our body, which are the ways in which our cells get important messages about things that need repair or protection. This includes maintaining our body's blood pressure levels.
