Diabetes: The food less than 40p that could control your blood sugar levels

Type 2 diabetes is far more common in the UK, affecting around 90 percent of people with diabetes. The crucial aspect of diabetes is blood sugar control. Here’s one cheap food perfect for the coming winter months that might be beneficial for your glucose levels as long as you opt for the right type.

This can help individuals with diabetes control their blood sugar.

One type of sweet potato that doesn’t tick the low glycemic index box is orange sweet potato.

However, when you boil this type, it seems to have a lower glycemic index compared to when you bake or roast it, according to PubMed central.

Recent research by Science Direct suggests that more studies need to be conducted to determine the exact glycemic indexes of sweet potatoes and the impacts on glucose and glycemic response.


The same study also found that polyphenol-rich purple potatoes can lower glycemia, inflammation and even insulin.

Apart from the glycemic index, another health benefit of sweet potato is its high levels of magnesium.

Magnesium and fibre can help to reduce insulin resistance and stabilise blood sugar.

One study even found that magnesium supplementation or increased intake of magnesium-rich foods may be an important tool in the prevention of type 2 diabetes in obese children.

Another beneficial type seems to be Japanese sweet potato.

A study published in the Journal of Nutrition and Metabolism showed that Japanese sweet potato extract called Caiapo could be helpful for people with diabetes.

Caiapo had a beneficial effect on the plasma glucose and cholesterol levels in patients with type 2 diabetes.

In general, sweet potatoes are packed with fibre, vitamins A, C and B6, which can be beneficial for your overall health, Diabetes UK reports.

The charity recommends roasting sweet potatoes with other vegetables like carrot, beetroot and three teaspoons of paprika.

Based on the research into sweet potatoes and their effect on diabetes patients, it’s important to choose the right preparation method to ensure they are actually beneficial for blood sugar levels.
