Sweet potato and lentil soup is one of my favourite soups.  It’s quick, easy and full of nutrients.  It also makes a change from pumpkin soup! 

A bit about sweet potato 

Sweet potatoes are highly nutritious, and a great addition to your diet.  They come in a variety of colours – orange, purple or white.  They are rich in fibre, antioxidants and vitamins and minerals such as vitamins A, C and B6, as well as, magnesium, manganese and potassium.

Sweet potatoes contain both soluble and non-soluble fibre, making them great for gut health and keeping you full for longer.  The soluble fibre helps bulk up stool and reduce constipation, while the non-soluble fibres are a food source for the beneficial bacteria living in your large intestine.  Therefore, fibre-rich diets have been linked to better bowel motions and a reduced risk of colon cancer.

Sweet potatoes are important for immunity and eye health.  Orange sweet potatoes get their colour from the antioxidant beta-carotene.  The body converts beta-carotene into vitamin A, which is essential for good immunity and eye health.  Additionally, vitamin A is also important for gut health, it helps reduce gut inflammation and helps keep the lining of your gut healthy.

Sweet potatoes have a relatively low GI, making them good for blood sugar regulation and safe for people with diabetes.  The sugars contained within them are slowly released into the bloodstream, thus reducing blood sugar spikes.
