5 Signs You Have A Garlic Intolerance

5 Signs You Have A Garlic Intolerance

Garlic is a powerful anti-inflammatory compound and one of the most widely used cooking ingredients, found in practically every cuisine in the world. For someone who has a sensitivity to garlic it’s widespread use can be a nightmare. An intolerance to garlic can easily go under the radar, especially since more obvious culprits, such as gluten and dairy are so widespread nowadays.

I’m 100% Italian but I have a secret – I don’t eat garlic! The reason? I believe I’ve developed an intolerance to it over the years. I’m confident in my ability to self-diagnose since there’s no denying the symptoms I get post consumption of garlic – sometimes even after the most minimal amounts. When I tell people that I do not eat garlic the usual response is always “But you’re Italian?!” Sure, I’m Italian, however, not all Italians consider garlic a main component of every meal. Take for example the Sardinians, albeit they cook with garlic, they usually remove the large pieces of garlic before serving and only add them in recipes to add a touch of garlicky flavour.

The flavour or garlic is one thing, and consequently easily digested. On the other hand, profuse amounts of potent garlic wreak havoc on my entire body, causing side effects such as lethargy, foggy-brain, and headaches. Garlic intolerance symptoms are often delayed and can take hours or, in some cases, up to a day or more to appear. Different people experience garlic intolerances in different ways. As with all food intolerances, garlic intolerance symptoms are highly individual. These 5 signs will help you understand if you have a garlic intolerance:

  1. Digestive Issues
    Consuming too much garlic can cause cramping, nausea, vomiting or diarrhea, and stomach acids mixed with the strong compounds of cooked or raw garlic can have a burning effect in the stomach.
  2. Excessive Garlic Body Odour
    We all know that consuming large amounts or garlic often results in body odour, but for those with an intolerance to garlic even the smallest amount can cause this. Garlic breath is a result of the sulphur from the garlic being released into to the lungs and expelled from the body.
  3. Unexplained Fatigue
    In some cases, the day after consuming garlic people can suffer from extreme fatigue, with severe cases including prolonged chronic fatigue. Lethargy, foggy-brain and overall weakness are also symptoms of a sensitivity to garlic.
  4. Low Blood Pressure
    Garlic is known to be an essential compound for reducing blood pressure. However, those with a garlic sensitivity who also suffer from low blood pressure can experience exaggerated signs of low blood pressure after consuming garlic, including lethargy, ringing in the ears, and headaches.
  5. Insomnia
    Regular, excessive consumption of garlic can apparently affect your sleep. Despite the suggestions that garlic helps us sleep better, those with an intolerance can suffer from the opposite effects.

Do you think you suffer from a garlic allergy? What are your symptoms?

    One of my favourite flavours was garlic and truthfully, it still is. But the effects on my body is so bad, I have given it up altogether. Even just the smallest amount, cooked or raw, will cause my stomach to distend and I feel in so much pain for up to 72 hours after. I look like I’m nine months pregnant, and for a 57 year old, the look is alarming I wish there were something that I could take that diminishes the pain and distension when I have inadvertently eaten garlic. Are there any ideas out there that have helped?

    • Wow! My intolerance is nowhere near that bad! I really don’t know what would help for those symptoms, except to not eat garlic! If I am eating out in a restaurant I’ll make sure to drink a ton of water…it’s so hard to avoid, especially in restaurant food because garlic is in everything!!! What if you used garlic salt, as opposed to raw garlic? Or garlic flavoured oils? Have you tried those options?

  • I never thought garlic affects sleep. Very informative. Great post!

  • Honestly I didnt know that there was such a thing. But I guess there are intolerance for everything. I would have never thought of these things being from Garlic. Thank you for this information. Could help people feel better!

    I’d be forever sad if I couldn’t have garlic .. I put it in everything it seems! I’m so glad you started the conversation. Food intolerances and sensitivities can be a big deal health wise for people .. and sometimes it’s hard to know unless you have a blood test.

    • Definitely! I actually KNOW that every time I eat an excessive amount of garlic, I feel horrible the next day.

  • Really interesting. I love garlic. I’m glad I haven’t had any intolerance. Nice share here, really informative.

  • Wow this was very educational! I had no idea people could get an allery or an intolerance to garlic. I am glad I dont because it actually is a great healing root to have around for holistic reasons.

    • It is definitely an amazing ingredient for holistic purposes, and it does frustrate me that I can’t eat it!
