Questions about spaghetti squash

What the numbers say to the questions people actually search.

How many calories are in a portion of spaghetti squash?
A typical portion (80 g, one of your five a day) gives 18 kcal. Per 100 g the figure is 23 kcal.
Does baking change the vitamin C in spaghetti squash?
Yes. Per 100 g, vitamin C goes from 2 mg raw to 3 mg baked. Part of that is the vitamin or mineral itself changing, part is the change in water content.
Which vitamins and minerals does spaghetti squash have most of?
By share of the daily reference intake: vitamin B6 (0.1 mg, 7.1 %), niacin (1 mg, 6.3 %) and potassium (120 mg, 6 %) per 100 g.
Is spaghetti squash high in salt?
No. Salt is 0.05 g per 100 g, which is very low under UK rules.
How these numbers were made
Every figure comes from the UK Composition of Foods Integrated Dataset (CoFID), 2021 edition, record 13-358, Squash, spaghetti, baked, published by Public Health England under the Open Government Licence v3.0. Main data references: As raw. Values are per 100 g of the edible part; a portion is 80 g, one of your five a day, the usual UK portion for vegetables. Reference intakes follow Regulation (EU) 1169/2011 Annex XIII as retained in GB law; “source of”, “high in” and “low” follow Regulation (EC) 1924/2006, assessed per 100 g. Function lines are the authorised wording from the GB register of nutrition and health claims, credited to the nutrient. Energy is rounded to the whole kcal and kJ; other amounts to one decimal, or two below 1. A trace is shown as “trace” and never gets a figure or a badge; a nutrient never analysed is left off the page. We start from the dataset’s 2,887 records and keep 2,322: records weighed with bone, shell or skin, alcoholic drinks, infant foods, brand-named products, records with fewer than eight measured vitamins and minerals and near-identical variants are left out. Group context uses the 240 vegetables kept from the dataset; a rank counts only the foods with a measured figure for that nutrient. Food images are illustrations from Ingredient Atlas, released under CC0; they show the food, not the measured sample, and where no illustration of the exact food exists the nearest one is shown (here: Spaghetti Winter Squash). Checked 5 October 2026. Contains public sector information licensed under the Open Government Licence v3.0.
