Makhana and Blood Sugar: What the Research Says

With a glycaemic index of approximately 55, makhana is a genuinely smart snack choice for blood sugar management. Here's the science behind that claim.

India has the largest diabetic population of any country in the world — over 100 million people living with type 2 diabetes, and hundreds of millions more in the pre-diabetic range. For this population, and for the vast majority of health-conscious people who simply want stable energy throughout the day, the glycaemic index (GI) of foods matters enormously.

Makhana's GI of approximately 55 places it firmly in the "low glycaemic" category — and this single fact has significant implications for how and why you should be eating it.

What is the Glycaemic Index?

The glycaemic index measures how rapidly a carbohydrate-containing food raises blood glucose levels, on a scale from 0 to 100. Pure glucose is the reference point at 100. Foods are categorised as:

CategoryGI RangeEffect on Blood Sugar
Low GI55 and belowSlow, gradual rise — sustained energy
Medium GI56–69Moderate rise — moderate energy spike
High GI70 and aboveRapid rise — energy spike and crash

A food's GI is influenced by its fibre content, protein content, the structure of its starch molecules, and how it's processed or cooked. Foods that are high in complex carbohydrates, protein or fibre tend to have lower GI scores because they are digested more slowly.

How does makhana compare?

Here's where makhana stands relative to common snacks and foods:

FoodGlycaemic Index (approx.)Category
Aroshya Makhana (roasted)~55Low GI
Brown rice~68Medium GI
Whole wheat bread~69Medium GI
Cornflakes~81High GI
Rice cakes~82High GI
White bread~75High GI
Popcorn (plain)~72High GI
Almonds~0–15Very Low

The comparison with rice cakes is particularly striking. Rice cakes are widely marketed as a "healthy, light" snack, yet their GI of ~82 means they spike blood sugar faster than white bread. Makhana, with a GI of ~55 and meaningfully more protein, is a substantially better choice for anyone watching their glycaemic response.

Why makhana has a low GI

Makhana's favourable glycaemic profile comes down to three factors:

Resistant starch: A portion of makhana's carbohydrate content exists as resistant starch — a type of carbohydrate that resists digestion in the small intestine and instead ferments slowly in the large intestine. This slows glucose absorption significantly.

Protein content: At approximately 9.7g protein per 100g, makhana has a meaningful protein content for a plant-based snack. Protein slows gastric emptying, which reduces the speed at which carbohydrates enter the bloodstream.

Low simple sugar content: Unlike many snacks that contain added sugars or easily hydrolysed simple carbohydrates, makhana's carbohydrates are predominantly complex — which inherently means slower digestion.

What this means for people managing diabetes

Makhana's low GI makes it a sensible snack choice for people with type 2 diabetes or insulin resistance. It provides energy without a sharp insulin demand, which is the critical consideration for blood sugar management.

Some small studies have also investigated makhana's potential hypoglycaemic properties more directly. Animal studies have found that makhana seed extracts may help improve insulin sensitivity, though this research is at an early stage and should not be taken as clinical evidence. Human trials are needed before any firm medical claims can be made.

What we can say confidently is this: swapping high-GI snacks (rice cakes, cornflakes, white bread-based snacks) for makhana is a meaningful dietary change with a reasonable evidence base behind it.

Practical guidance

A few things worth knowing about makhana and blood sugar in practice:

  • A sensible serving size is 30g (a small handful). This provides roughly 100 calories, 3g protein and a moderate carbohydrate load
  • Combining makhana with a small amount of fat (a few nuts or a piece of cheese) further lowers the glycaemic impact of the overall snack
  • Flavoured varieties — particularly those with added sugar — will have a higher effective GI. Aroshya's flavoured range uses no added sugar
  • As always, people managing diabetes should discuss dietary changes with their endocrinologist or registered dietitian

Makhana is not a medical intervention. But it is a genuinely good food that earns its place in a health-conscious diet — and for a country navigating a diabetes epidemic, foods that are both delicious and metabolically intelligent deserve far more attention than they typically receive.
