Is Garlic Acidic?

When it comes to measuring the acidity of a food, the pH scale is commonly used. This scale ranges from 0 to 14, with 0 being the most acidic, 7 being neutral, and 14 being the most alkaline. Foods with a pH of less than 7 are considered acidic, while those with a pH greater than 7 are alkaline.

So where does garlic fit on this scale? Raw garlic typically ranges from 5.3 to 6.3, which means it is slightly acidic. However, this pH level only refers to the raw garlic before it is eaten. Once garlic is metabolized in the body, it becomes alkaline-forming due to its high content of sulfur-containing compounds such as allicin. These compounds help to neutralize acid in the stomach and promote a healthy pH balance in the body. It's worth noting that the pH of garlic can vary depending on several factors, including the type of garlic, how it's prepared, and the conditions it's stored in.


Why Does pH Level Matter?

Well, the pH level of the foods we consume can impact our overall health. When our body becomes too acidic, it can lead to a variety of health problems, such as inflammation, acid reflux, and even cancer. By consuming alkaline foods, we can help keep our body's pH level in balance and reduce the risk of these health issues.

Garlic and Acid Reflux

If you suffer from acid reflux, you may be wondering if garlic is safe to eat. Acid reflux is a condition where stomach acid flows back up into the esophagus, causing a burning sensation in the chest and throat. Certain foods, including those that are acidic, can exacerbate symptoms of acid reflux. While garlic is technically acidic, it's not considered a highly acidic food. In fact, many people with acid reflux find that they can eat garlic without experiencing any adverse effects. However, everyone's body is different, and what works for one person may not work for another. If you're concerned about how garlic may affect your acid reflux, it's a good idea to talk to your doctor or a registered dietitian. They can help you determine which foods are safe for you to eat and which ones to avoid.

The Chemistry of Garlic -What is Allicin?

Firstly, let's start with the basics. Garlic is a member of the allium family, which also includes onions, leeks, and shallots. It contains a compound called allicin, which is responsible for its distinctive smell and taste. When garlic is crushed or chopped, the enzyme alliinase is activated, which then converts alliin into allicin. Allicin is known to have potent antimicrobial properties and is responsible for many of garlic's health benefits.

Once allicin is formed, it quickly reacts with other compounds in garlic and is transformed into a number of different sulfur-containing compounds. These compounds are responsible for many of the health benefits associated with garlic. One of the main ways that allicin works in the body is by acting as an antioxidant. It can help to protect cells and tissues from damage caused by harmful molecules known as free radicals, which are produced naturally by the body and can also be found in the environment. Allicin has also been shown to have antimicrobial properties, meaning that it can help to kill or inhibit the growth of certain types of bacteria, viruses, and fungi. This may be why garlic has traditionally been used to treat a wide range of infections and illnesses, including the common cold and flu.

In addition, allicin has been found to have anti-inflammatory effects, which means that it can help to reduce swelling and inflammation in the body. This may be particularly useful in the treatment of conditions such as arthritis and other inflammatory disorders. However, it is important to note that allicin is a relatively unstable compound that is quickly broken down in the body. This means that the health benefits of garlic may not solely be attributed to allicin, but also to other compounds found in garlic.

Overall, while garlic is not acidic, it contains compounds like allicin that have a range of health benefits. Incorporating garlic into your diet may help to promote overall health and well-being. However, it is always important to speak with a healthcare provider before making any significant changes to your diet or lifestyle.

What are the Health Benefits of Garlic?

Garlic is also packed with potential health benefits, including:

  1. Boosting the immune system: Garlic contains compounds like allicin, which have been shown to have immune-boosting properties. Consuming garlic regularly may help strengthen the immune system and reduce the risk of infections.
  2. Lowering cholesterol levels: Studies have shown that consuming garlic may help lower LDL (bad) cholesterol levels and reduce the risk of heart disease.
  3. Fighting inflammation: Garlic contains anti-inflammatory compounds that may help reduce inflammation throughout the body. This can be beneficial for people with conditions like arthritis or asthma.
  4. Supporting brain health: Garlic contains antioxidants that may help protect the brain from oxidative damage and reduce the risk of age-related cognitive decline.


In conclusion, garlic is slightly acidic with a pH of 5.3, but once metabolized in the body, it becomes alkaline-forming due to its high content of sulfur-containing compounds such as allicin. Allicin, a compound responsible for garlic's distinctive smell and taste, has potent antimicrobial and antioxidant properties, making it beneficial for overall health and wellbeing. Incorporating garlic into your diet may help boost the immune system, lower cholesterol levels, fight inflammation, and support brain health. However, it's always important to speak with a healthcare provider before making any significant changes to your diet or lifestyle.
