Frugal Food: Winter Squash

As part of Nutrition to Fit’s Frugal Food Favorites series, each week we highlight a favorite affordable food and all of its nutritional benefits, in addition to ways and recipes to include it in your life. This week is all about winter squash!

This week’s frugal food is embracing a type of affordable seasonal produce that has many varieties: winter squash. Winter squash includes butternut squash, kabocha squash, red kabocha squash, carnival squash, sugar pumpkin, sweet dumpling squash, spaghetti squash, blue hubbard squash, delicata squash, red kuri squash, buttercup squash, acorn squash, and more! (Check out this Epicurious article that talks specifically about the flavor characteristics of each of these types of squash.)

May Reduce Risk of Eye Disease

Winter squash is an excellent source of carotenoids, like alpha-carotene and beta-carotene. Several studies also show that winter squash as a top three food source of lutein, zeaxanthin, and beta-cryptoxanthin (1). All of these carotenoids are antioxidants that working in reducing disease risk, especially eye disease (2). Lutein and zeaxanthin in particular may be protective in eye disease because they absorb blue light (the light from electronics and energy-efficient lightbulbs that is particularly harmful at night) that is damaging to the eyes (2, 3).

Antioxidant Powerhouses

On top of being the number one source of carotenoids, winter squash possesses other antioxidants, too. They contain vitamin C, manganese, and recent research is suggesting the cell wall polysaccharides also have antioxidant properties (1). Think of antioxidants as like little superheros that prohibit (and sometimes even prevent) damage to our cells caused from oxidation.

Anti-Inflammatory

Winter squash isn’t fat free, but it is low fat (less than 15% of calories come from fat). The awesome thing about this, is that for a low-fat vegetable, you can actually get a decent amount (340 mg) of anti-inflammatory omega-3 fats in the form of alpha-linolenic acid (1). There is also a type of molecule in winter squash called cucurbitacins, which have properties that can make them anti-viral, anti-bacterial, and anti-inflammatory.

Blood Sugar Regulation

Winter squashes are typically pretty starchy (of course there will be variation among the different varieties). Not all starch works the same in our bodies, though .The type of starch in winter squashes is more complex, with the carbs coming from polysaccharides in the squash’s cell walls (1). This includes the soluble fiber pectin, which can have heart-healthy benefits as it absorbs cholesterol, and recent animal studies are showing may also have antioxidant, anti-inflammatory, anti-diabetic and insulin-regulating properties. For your blood sugar, this means you won’t see dramatic blood sugar rises and falls with the polysaccharides in winter squash.

Additionally, more research is showing that nutrients found in winter squash (like the B-vitamin like compound d-chiro-inositol) can help with blood sugar regulation. B-complex vitamins actually work closely in our body’s blood sugar regulation, and winter squash is unique in that it contains a fair amount of five B-complex vitamins (B1, B3, B6, pantothenic acid, and folate).

Heart-Healthy

With the soluble fiber from pectins and all of the antioxidant and anti-inflammatory properties of winter squash, they can (and should!) be a part of a heart-healthy diet. There’s also emerging research suggesting that there may be unique substances in winter squash that may inhibit an enzyme called HMG-CoA reductase, which may help to partially block the production of cholesterol in our cells (1).

Winter Squash Selection + Storage

Choose winter squash that has a firm rind (softer may indicate a more watery flesh inside), and is hard, heavy, and dull (not glossy). The storage life will depend on the varietal (and how long it had already been stored when you purchased it), but depending on the type of squash it can be stored anywhere from one week to six months. Keep in a cool, dark environment. Once cut, cover and store in the fridge up to a couple days.

Tips for Use + Recipes

Wash the squash before use. I personally find it easier to steam, bake, roast, etc. the squash with the skin on, as it can be difficult to peel the tough rind. Cutting a squash in half first may help with peeling. If your squash is very large, you can cut the part you’re not currently using into small cubes and freeze, and these can easily be added to soups, stews, casseroles, oatmeals, etc.

For my mamas, winter squash can make excellent baby food! If you want to puree, just steam first and puree with a little breast milk, formula, or water if the consistency needs to be thinned. If you want small solids, you can chop squash pieces into smaller sizes and offer it to your child.

Also, food waste note: don’t throw away the seeds! The seeds from any type of winter squash can be rinsed and roasted, just like pumpkin seeds! This makes for an excellent, fibrous snack.

We have a TON of recipe contributions from dietitians around the web today, so be sure to check out all the different types of uses for the many varieties of winter squash. Bookmark this page and come back here anytime to consult this great compilation of recipes!

  1. I felt the same way - there were a couple that I didn't even know existed! (hello ambercut squash)
  2. Thanks for sharing, Jessica. Your recipe reminded me I haven't had delicata squash in far too long and need to remedy that!
