Type 2 diabetes is a condition in the which the body can’t control the amount of glucose in the blood. The body doesn’t respond to insulin (a protein hormone) properly, and may not produce enough. This then causes blood glucose levels to become too high. Someone with type 2 diabetes may experience symptoms such as excessive thirst, needing to pee more and tiredness. Left untreated, the condition can lead to serious complications, including kidney failure, nerve damage and heart disease.
So what can you do prevent the condition and lower blood sugar?
Eating a healthy diet is one way recommended by experts.
You should eat a wide range of foods – including fruit, vegetables and some starchy foods like pasta – and keep sugar, fat and salt to a minimum.
But specific foods have also been shown to have blood sugar lowering properties – one being cod.
Cod, a good source of protein, may help manage or prevent diabetes better than other types of meat.
This was demonstrated in a 2014 study which included data taken from 33,704 Norwegian women over a five year period.
The researchers found eating 75 to 100g of cold-water fish, including cod, reduced the risk of developing type 2 diabetes.
Other cold-water fish they found to be effective were saithe, haddock and pollock.
But it was also noted the reduced risk could also have been influenced by other lifestyle factors such as exercise.
Regular exercise has also been found to lower blood sugar.
You should aim to do 2.5 hours of activity a week, which could include fast walking, climbing stories, or doing more strenuous housework or gardening.
Another source of protein which has proven effective at lowering blood sugar is legumes.,
A 2012 study found incorporating legumes into a person’s diet improved glycemic control and lowered the risk of coronary heart disease in people with type 2 diabetes.
Examples of legumes include beans, chickpeas and lentils.
Experts believe their benefits may come from their nutrients – fibre, complex carbohydrates and protein.
