Is Nendran Banana Good for Diabetes?

IN MODERATION

Nendran needs more care than an ordinary banana. It is much larger and starchier — a single ripe nendran can carry as much carbohydrate as a serving of rice. It is not forbidden, but it should be counted as a carbohydrate portion, not treated as a light fruit snack.

Answered by Dr. Dante Ruskin · Diabetologist & Intensivist

Eat half a fruit at a time, steamed rather than fried, and let it replace part of your breakfast rather than accompany it. Nendran chips and pazhampori are fried preparations and belong in the occasional-treat category, not the daily one.

Why nendran is different

Ask a patient whether they eat bananas and they may say “just one a day” — but one poovan and one nendran are not the same food. Nendran is large, dense and starchy, cultivated across Kerala and Kanyakumari district as much for cooking as for eating raw.

A single ripe fruit can carry carbohydrate comparable to a serving of rice. That is not a reason to ban it; it is a reason to count it. The mistake is categorising nendran mentally as “fruit” — light, healthy, unlimited — when nutritionally it behaves like a starchy staple.

Ripeness and preparation

As nendran ripens, its starch converts to simple sugars and the glycemic effect climbs — the deep-yellow, soft fruit raises sugar faster than a firmer one. Preparation matters just as much.

Steamed nendran (puzhungiya ethakka) is the cleanest form: no added fat, an obvious portion, and often eaten with a little grated coconut which slows absorption slightly.

Unripe nendran cooked as a vegetable — in thoran or curry — is lower in sugar and a good choice.

Pazhampori (batter-fried ripe banana) adds refined flour, sugar and oil.

Nendran chips are fried in coconut oil and salted to encourage eating more.

The chips problem

Every household here has a tin of nendran chips at some point in the year, and wedding and festival gifting keeps a fresh supply arriving. Chips are a particular trap for diabetes because they hit three problems at once: a starchy base, deep-frying, and no natural portion limit — nobody eats four chips.

Patients rarely report them when asked what they eat, because chips feel like a snack rather than a meal. If your sugar readings are drifting upward without explanation during festival season, the tin on the shelf is worth investigating before anything else.

Making it work

If nendran is part of your household’s food — and in this region it usually is — the workable approach is straightforward.

Take half a fruit, steamed, at breakfast, and reduce the puttu, idli or rice at that meal accordingly.

Add a protein: egg, a few nuts, or a dal side. Avoid eating it as a mid-evening snack on top of dinner.

And check your sugar two hours afterwards once, to see your own response — variation between patients is substantial, and personal evidence is more persuasive than any general rule.

For patients on insulin

Because nendran carries a meaningful carbohydrate load, patients on mealtime insulin should account for it in their dosing rather than treating it as a free fruit. Those on sulfonylureas should keep intake reasonably consistent to avoid swings. If you are changing your breakfast pattern to include steamed nendran regularly, mention it at your next review so doses can be checked against your readings.

Frequently asked questions

About half a medium fruit at a time, steamed, and counted as part of that meal's carbohydrate — so reduce the rice, puttu or other staple accordingly. A whole large nendran eaten alongside a normal breakfast is a common cause of high mid-morning readings.

Yes — they are deep-fried, calorie-dense, and eaten by the handful with no natural stopping point, which makes them one of the least suitable snacks in diabetes. Keep them to rare occasions and small quantities rather than a routine purchase.

Steaming is the best of the common preparations — no added fat, and the portion is visible. Frying (pazhampori, chips) adds substantial fat and calories. Unripe nendran cooked as a vegetable is lower in sugar than the ripe fruit and a reasonable option.

It is a traditional practice, and nendran is genuinely nutritious — but for someone with diabetes it should still be portioned and counted. Half a steamed fruit with a protein source is a sensible version of the same intention.
