What are the 5 top health benefits of butternut squash?
1. May support eye health
Research has shown that phytonutrients, such as zeaxanthin and lutein, may help to protect eye health, and butternut squash contains both of these carotenoids. Beta-carotene, which we convert to vitamin A, also plays a role in eye health and healthy cell renewal, and diets that are high in brightly coloured fruits and vegetables, including butternut squash, are rich sources.
2. May support the immune system
3. May support bone health
There is some evidence to suggest that a varied diet rich in fruits and vegetables may reduce the risk of osteoporosis. A 2016 study found that diets high in vegetables, as well as those containing beta-carotene, vitamin C, zinc and sodium, were positively associated with healthy bone mass in postmenopausal women. All of these nutrients are found in butternut squash, making it a bone-loving vegetable.
4. May support digestion
Just 100g of butternut squash (baked) contains around 2g of fibre, which is 7% of the recommended intake of fibre for adults. There is strong evidence that fibre is associated with a reduced risk of heart disease, bowel cancer and type 2 diabetes, but it can also help digestion and prevent constipation.
5. May support weight management
Butternut squash is low in calories, high in fibre and has a comforting sweet flavour which may help manage appetite.
Is butternut squash safe for everyone?
Butternut squash is nutrient dense and a healthy food for the majority of us. However, those medicated with beta blockers or ACE inhibitors may be advised to minimise their intake of potassium-rich foods, including butternut squash.
An allergy to butternut squash is rare, but there have been some reports that contact dermatitis may occur.
If you are concerned or have queries please consult your GP or registered dietician for guidance.
