Iâll be honest, I believe that fresh foods are often better and healthier than their processed, powdered forms â and that includes garlic. Fresher herbs and spices generally retain more antioxidants and vitamins compared to dried versions.
So, whatâs the deal with garlic powder? I use it occasionally, but I really prefer fresh garlic, with its powerful scent and delicious taste when itâs added to food.
Nothing beats fresh garlic in my mind. BUT, garlic powder isnât a bad alternative if you donât have fresh cloves on hand. However, does it offer the same benefits as fresh garlic? Iâve decided to investigate.
Quick Answer
Is garlic powder good for you? Yes, garlic powder retains many of the same health benefits as fresh garlic. While it may lose some nutrients during processing, it still offers heart health support, helps fight harmful bacteria, reduces inflammation, and boosts immune health. Garlic powder is a convenient, shelf-stable alternative to fresh garlic that can be easily added to your diet to improve digestion and overall health.
How Is Garlic Powder Actually Made?
So, how does garlic go from fresh cloves to that fine powder sitting in your spice rack? The process is pretty straightforward.
First, fresh garlic cloves are peeled and sliced. Then, these slices are dehydrated at low temperatures to preserve as much of the garlicâs flavour as possible.
Once the garlic is completely dried, itâs ground into a fine powder that you can easily sprinkle over your favourite dishes.
What Happens During the Drying Process?
The drying process involves removing the moisture from the garlic cloves, which helps extend their shelf life. While this process is great for convenience, it does lead to some nutrient loss.
One of the first things to go is Vitamin C, which is highly sensitive to heat and light. So, if youâre using garlic powder hoping to get a dose of Vitamin C, youâre out of luck.
However, itâs not all bad news. Although drying reduces allicin, the compound responsible for many of garlicâs health benefits, thereâs a neat trick: allicin can still form when you add water to garlic powder.
Garlic powder contains alliin, a compound that turns into allicin when exposed to water, thanks to an enzyme called alliinase. So, while garlic powder might not pack the same immediate punch as fresh garlic, you can still get some of the benefits if youâre using it in recipes that involve water or moisture.
On top of that, garlic powder retains some other important nutrients like Vitamin B6, calcium, and manganese, as well as some sulfur compounds, which are responsible for garlicâs characteristic smell and some of its health benefits.
So, even though fresh garlic is still the gold standard, garlic powder is far from nutritionally voidâit just brings its benefits in a different form.
What Are the Benefits of Garlic Powder?
Garlic powder offers several health benefits beyond just adding flavour to your food. Letâs explore the most important ones.
Garlic Powder Supports Heart Health
One of the most well-known benefits of garlic, including garlic powder, is its positive effect on heart health. Studies have shown that garlic powder can help reduce cholesterol levels, particularly LDL cholesterol, which is the âbadâ kind that can lead to plaque buildup in your arteries. Lowering LDL cholesterol can reduce the risk of heart disease.
Garlic powder may also help lower blood pressure. A meta-analysis of clinical trials found that garlic powder significantly reduced both systolic (the top number) and diastolic (the bottom number) blood pressure.
If youâre looking for a natural way to support your cardiovascular system, adding garlic powder to your diet could be an easy step in the right directionâ.
Garlic Powder Fights Harmful Bacteria
Garlic powder has strong antibacterial properties thanks to a compound called allicin, which forms when the powder is mixed with water.
Allicin can help stop the growth of harmful bacteria like Helicobacter pylori (H. pylori), a type of bacteria that causes stomach ulcers and other digestive issues. This makes garlic powder helpful for supporting gut health
But thatâs not all. Garlic powder also fights bacteria that can cause food poisoning, like Salmonella and E. coli. These bacteria are common in contaminated food, and garlic powder can help protect against them.
In addition to allicin, garlic powder contains other sulfur compounds that work together to stop bacteria from functioning properlyâ. So, adding garlic powder to your meals isnât just about flavourâit can also help reduce the risk of foodborne illnesses.
Garlic Powder Reduces Inflammation
Garlic, including its powdered form, has anti-inflammatory effects, which can help reduce swelling and pain in the body. Studies show that garlic can lower markers of inflammation, like C-reactive protein (CRP) and tumor necrosis factor-alpha (TNF-α), which are linked to inflammation. This makes garlic powder a useful option for managing conditions like arthritis.
One marker that garlic doesnât seem to affect as much is interleukin-6 (IL-6). IL-6 is a protein that plays a key role in the immune system, promoting inflammation when the body is fighting off infections or dealing with injury. While garlic powder doesnât significantly reduce IL-6, it still helps lower other important inflammatory markersâ.
Garlic Powder Supports Your Immune System
Garlic powder can help boost your immune system and may even have antiviral effects. When you mix garlic powder with water, it creates allicin, a compound that helps your body fight off infections. Studies show that allicin can stop viruses like the flu, herpes, and even SARS-CoV-2 (the virus that causes COVID-19) from spreading in the body.
Allicin works by blocking viruses from entering cells and stopping them from multiplying. This makes garlic powder a useful way to support your immune health. Some research also suggests that garlic can help you recover faster from colds and other viral infectionsâ.
Although we need more studies to fully understand how well garlic powder works, the allicin it forms means it can offer some of the same immune-boosting and antiviral benefits as fresh garlic.
Garlic Powder Contains Antioxidants
Garlic, including its powdered form, contains antioxidants, which help protect your cells from damage caused by free radicals. Free radicals are unstable molecules that can damage cells and contribute to aging and diseases like heart disease and cancer. The antioxidants in garlic powder may help slow down the aging process and reduce the risk of these chronic conditions.
While garlic powder may have slightly fewer antioxidants than fresh garlic, it still retains enough of these beneficial compounds, such as allicin and other organosulfur compounds, to offer protective effects. These compounds help neutralize free radicals and can support overall healthâ.
Garlic Powder Supports Digestive Health
Garlic is known for its potential to support digestive health by helping to balance the gut microbiomeâthe collection of bacteria in your digestive system. Studies show that garlic, including its powdered form, contains compounds like allicin that can promote the growth of beneficial bacteria in the gut while inhibiting harmful bacteria, such as Helicobacter pylori (H. pylori), which can cause stomach ulcers.
By helping to maintain a healthy balance of gut bacteria, garlic powder may help prevent digestive issues and support overall gut health.
Is Garlic Powder as Good for You as Fresh Garlic?
Fresh garlic has higher levels of allicin and Vitamin C, giving it a slight edge in potency. However, garlic powder still provides many of the same health benefits in a more convenient form.
While it may not match fresh garlicâs immediate effects, garlic powder retains enough of its active compounds to make it a valuable, shelf-stable alternative for supporting heart health, digestion, and immunity.
What About the Side Effects?
While garlic powder offers many health benefits, itâs important to be aware of potential side effects. Some people may experience stomach issues like heartburn, gas, or bloating when consuming garlic, including garlic powder. These digestive issues are more likely if you consume large amounts of garlic powder or if you have a sensitive stomach.
Additionally, garlic (both fresh and powdered) may thin the blood, so if you are taking blood-thinning medication, you should consult your doctor before increasing your garlic intake. Some people may also experience allergic reactions to garlic, though this is rare.
In most cases, garlic powder is safe when used in moderate amounts in cooking, but if you notice any discomfort, itâs best to adjust your intake.
The Bottom Line
Garlic powder may not have all the nutrients of fresh garlic, but it still offers many of the same benefits. Itâs a convenient way to add heart-healthy, immune-boosting, and digestive-supporting compounds to your meals. Whether youâre using it for flavour or health, garlic powder is a great option to keep in your kitchen when fresh garlic isnât available.
