CONTROVERSIAL TAKE: Glycemic Index Is the Most Misunderstood Number in Nutrition.

CONTROVERSIAL TAKE: Glycemic Index Is the Most Misunderstood Number in Nutrition.

Everyone keeps shouting “high GI bad, low GI good.”
Sorry, but that’s oversimplified nonsense.

Here’s the truth most people don’t want to hear:

👉 Not all high-GI foods are harmful.
👉 Not all low-GI foods are healthy.
👉 Portion size and total carbs matter FAR more than GI.

Let me explain — simply and scientifically.

What GI Actually Measures

Glycemic Index = how FAST a food raises blood sugar compared to pure glucose (GI = 100).
It’s not measuring how much sugar enters your blood.
Just the speed.

Useful for diabetics, yes.
Misused by everyone else, absolutely.

Example 1: The Watermelon Myth 🍉

Watermelon has a GI of ~70 — same as white rice.

Sounds scary?
Only if you ignore basic math.

A typical 200g serving of watermelon has ~15g net carbs.

Glycemic Load (GL) = GI × carbs ÷ 100
GL = 70 × 15 ÷ 100 = 10.5

A GL above 20 is considered high — for diabetics.

Conclusion?
Watermelon is absolutely fine for most people.
High GI, low actual impact.

Example 2: The “Healthy” Sweetener Lie — Dates 🍫

Dates have a low GI (~42).
So everyone uses them as “healthy sugar.”

Except… they forget the load.

Two medium dried dates (~40g) = ~30g carbs.
GL ≈ 12.6

That's HIGHER than 200g of watermelon.

And in chocolate bars or “healthy sweets,” you need a LOT more dates than sugar to get the same sweetness… and because it’s marketed as “natural,” people eat double.

Low GI, high load = misleading health halo.

The Real Lesson

Stop demonizing single numbers.
Stop glorifying “healthy substitutes.”
Stop copy-pasting GI charts without context.

Focus on:

  • total carbs

  • portion size

  • how much you actually eat

  • your own metabolic response

If a recipe calls for sugar, use sugar.
If it needs jaggery, use jaggery.
If it needs dates, use dates.
Food isn’t supposed to be “bio-engineered healthy.” It’s meant to be enjoyed — in moderation.

That’s the part people forget.

If you found this simple, you’re welcome.
If it made you uncomfortable… even better. 😉
