Vitamin A
The orange of pumpkin is beta-carotene, which the body cuts into vitamin A as it needs it. As with carrots and sweet potatoes, it is absorbed better when eaten with a little fat.
Mechanism · 2
Mechanism · Orange is raw material, oil the carrier
The orange of pumpkin is beta-carotene, which the body cuts into vitamin A as needed. It does not dissolve in water and has to enter micelles formed with fat before it can be absorbed; when the body already has enough vitamin A, conversion slows, so the surplus does not keep turning into retinol.
Numbers · Vitamin A and blood glucose, counted apart
Cooked pumpkin is about 90% water. Its glycemic index (GI) is on the high side, but a 150 g serving holds only about 12–15 g of digestible carbohydrate, so its glycemic load is not high; its vitamin A and its effect on blood glucose are two separate ledgers. Pumpkin also contains some potassium, which people who need to limit potassium should count.

READ THE ORIGINAL

The orange in pumpkin is beta-carotene. In the small intestine your body cuts it into vitamin A as needed, and that step depends on a little fat in the same meal. A later chapter, on how the orange becomes vitamin A, walks that route from start to finish.

Everyday pumpkin can be read as three things stacked together:

Water is most of it: a bowl holds much less carbohydrate than your eye guessesWhat remains is mostly carbohydrate: protein and fat are both low, so it belongs in the staple column, not with the greensThe orange itself is a nutrient: it is the raw material your body uses to make vitamin A
So "pumpkin spikes blood sugar, and people with diabetes can't eat it" is a mix-up — it is about nine-tenths water. "Pumpkin is a weight-loss food" oversimplifies too — it is still carbohydrate, and whether it saves calories depends on what it replaces.

There are several varieties, all in the squash genus of the gourd family. As long as the flesh is orange, the three points above hold; the varieties differ mainly in sweetness and in how floury they are.
