Scientific reason for not eating onion and garlic

 

What’s the Real Scientific Reason for Not Eating Onion and Garlic? Let’s Dive In

Ever noticed how some people totally avoid onion and garlic—not just in temples but in daily food too? If you’ve grown up in India, you’ve definitely seen families, especially in spiritual or yogic circles, skip these two humble kitchen staples. The usual answer is “religion,” but hang on… there’s some actual science behind this, too. Curious? Here’s what I found out, minus the internet mumbo-jumbo and in plain, real talk.

🍽️ The Curious Case of Onion and Garlic: Not Just About Taste

So, why is it that onion and garlic are such a big deal for some?
Both are flavor bombs, no doubt. But for centuries, Ayurveda and certain traditions have said “maybe skip it” if you’re on a spiritual journey—or have a dodgy stomach.

But is this just a culture thing, or is there an actual scientific reason for not eating onion and garlic? Let’s break it down.

🧄 So, What’s the Science?

Let’s get honest for a second:

  • Onion and garlic are full of sulfur compounds (that’s the stuff that makes you cry when you cut an onion).

  • For folks with sensitive bellies or gut issues (hello, IBS club!), these sulfur-y things can cause bloating, gas, or just… not-fun feelings after a meal.

  • In science-speak, onions and garlic are “high FODMAP foods.” That means some people digest them poorly, while others don’t feel a thing.

  • There’s also a bit about how they might stimulate your nervous system, so if you’re deep into yoga, meditation, or just want to stay chill, some say best to skip.

🚫 Who Actually Skips Them?

  • People with gut issues: If you ever felt gassy after onion-heavy food, now you know.

  • Spiritual folks: Monks, yogis, or those on “sattvic” diets might skip these to keep their mind calm.

  • Those on blood thinners: Garlic especially can thin your blood, which is not always a good thing if you’re on certain meds.

But for most people? These two are superfoods—full of good stuff, if your tummy’s on board.

🧘 The Whole Yogic and Ayurvedic Angle

Not everything is just about physical health. Some old-school yogis genuinely believe food affects your mind, and onion and garlic “disturb the calm.” Whether or not you buy that, it’s definitely a thing in many Indian homes and spiritual retreats. (Trust me, I tried a garlic-free diet once at a yoga camp. It’s… different!)

.🥦 If You’re Skipping Onion and Garlic, What’s Left?

You’d think food would taste bland, but honestly, Indian kitchens have hacks for everything:

  • Hing (asafoetida), fennel seeds, ginger, coriander stems—these can make your tadka pop even without onions and garlic.

  • Jain recipes? Seriously next-level.

🌱 Real Life: What Happens When You Go Off Onion and Garlic?

I tried ditching both for a week, just to see what the fuss was about. First couple of days, my dals tasted strange, and I missed the kick in my curries. But after a few days, I felt less heavy after eating, and my stomach felt… settled?
My mom, on the other hand, says she’s never felt better after giving up onions and garlic during festive months.
So, is it for everyone? Maybe not. But is it worth trying if you’ve got stomach issues or want to meditate like a monk? Why not.

Real-Life FAQ: Scientific Reasons for Not Eating Onion and Garlic

Why do some folks just refuse to eat onion and garlic?

You’d laugh, but honestly, it’s not just old family superstition. I remember this one dinner—my uncle went on a rant about how onions give him a “cloudy head.” At first, I thought he was joking. But later, I learned there’s something in these veggies (FODMAPs and all that) that actually messes with some people’s stomachs and, weirdly, their mood too. So yeah, it’s not just in their heads!


Is there a real science reason behind this, or is it all religious stuff?

Okay, so both! Ayurveda and some ancient yoga books say onion and garlic “heat up” your body and make you restless—kind of the opposite vibe of meditation, right? But here’s the cool part: some actual doctors agree, especially for people with sensitive tummies. I met someone at work who stopped eating onions, and she said her IBS symptoms just… disappeared. Science does back that for certain people.


Will I get sick if I stop eating onion and garlic?

No way! My nani hasn’t touched them in 40 years and she’s still beating me at Ludo. Most Jain and Sattvic recipes don’t use either, and their food still slaps. But, fair warning, your taste buds might miss that “kick” for a week or two. After that? You probably won’t even notice.


What actually happens if you eat garlic every day?

So, my college roommate once tried those garlic pills—big mistake. Garlic does all sorts of things: some good, like helping your heart, and some weird, like thinning your blood (bad if you’re on meds or getting surgery, FYI). And if you overdo it? Yeah, you’ll probably clear a room with your breath!


Why do monks or yogis avoid these?

Here’s a story for you: My yoga teacher told us about his time at an ashram—no onions or garlic allowed. He said they “disturb the mind” and make it tough to meditate for hours. At first, I rolled my eyes, but he swears his mind feels “quieter” without them. I guess for folks chasing that inner peace, it matters!


What do people even use instead of onion and garlic in Indian cooking?

Honestly, I thought food would taste like boiled cardboard. Nope! Hing (asafoetida) is the real MVP, plus ginger, fennel, even a bit of fresh coriander stem. Jain food is next-level creative. You end up discovering flavors you didn’t know existed.


My stomach always feels weird after eating a heavy curry—could onions or garlic be to blame?

Honestly, maybe. A lot of folks only realize onions or garlic are the culprits after cutting them out. Not everyone’s gut likes those sulfur-y FODMAP things. I’d say, try a week without, see if you feel lighter. That’s what my friend did—now she swears by it.


If onions and garlic are so “bad,” why does everyone eat them?

This one cracks me up! Most people are totally fine eating them—heart health, immunity, all that jazz. It’s just certain folks, especially in India, who skip them for spiritual or health reasons. For most of us, they’re just delicious.


Is there any harm in eating a little bit now and then?

I mean, come on, life’s too short to never have garlic bread, right? Unless your doctor or your body says otherwise, enjoy in moderation. That’s what even most nutritionists say.


Does cutting out onion and garlic make you a “better” person?

Pfft, not at all! Food is personal. Some people feel more peaceful, others just feel left out at pizza night. Listen to your body—and maybe your grandma—and you’ll be fine.


Bottom Line?
If you’re skipping onions and garlic, it’s probably for a good reason—spiritual, medical, or just because you want to. But for most of us, these two are just another tasty part of life.
