5 Types of Food That Can Help Keep Diabetes At Bay

Diabetes is a chronic disease which affects millions of people across the world. In cases where the condition is uncontrolled, patients are at risk of blindness, kidney failure, heart disease and other serious health conditions (1).


Before diabetes is diagnosed, individuals go through a period in which their blood sugar levels become high but not high enough that they can be diagnosed with diabetes. This condition is known as pre-diabetes. The condition is marked by abnormally high blood sugar levels which are often due to insulin resistance (2).

Your diet is associated with pre-diabetes risk –if you are eating more calories than your body requires, these calories will eventually get stored as fat causing you to gain weight. Body fat - especially body fat which is stored around the abdomen is linked to insulin resistance (3).

Although certain risk factors for the development of diabetes cannot be changed, such as age, genetics and past lifestyle choices, there are actions that you can take to reduce your risk of developing type two diabetes. The key is early intervention, it is important to get your blood sugar levels out of the pre-diabetes range and to eat the right kinds of foods (4).



5 tips to help keep diabetes at bay



1. Cut Out Sugars And Refined Carbs From Your Diet

By eating sugary foods and refined carbs, those who are already at risk will then be on the fast track to developing diabetes, as these foods increase blood sugar and insulin levels (5, 6, 7). Many studies have also found that people who have a high intake of fast-digesting carbs are forty percent more likely to develop diabetes than those who have lower intakes (8).


2. Choose Water As Your Main Drink

Researchers who studied the effects of sweet drinks on diabetes, found that it is best to avoid sweetened beverages and fruit juices if you want to prevent the development of diabetes (9). Instead, an increased water intake can provide benefits in terms of better blood sugar level control and insulin response (10, 11).

A twenty-four week study found that overweight participants who drank water in place of diet sodas during their weight loss programmes were experiencing a decrease in insulin resistance, lower fasting blood sugar levels and insulin levels (11).


3. Follow A Very Low Carb Diet

There has been consistent research which suggests that very low carbohydrate diets can lower blood sugar and insulin levels, increase sensitivity to insulin and also reduce other risk factors for diabetes (12, 13, 14, 15).

A study of obese men who had pre-diabetes and were asked to follow a ketogenic diet found that their average fasting blood sugar levels decreased from 118 to 92 mg/dl, which is well within the normal range. Participants also ended up losing weight and improved several others of their health markers (14).


4. Eat A Diet Which Is High In Fibre

Studies which had obese, elderly and prediabetic participants have found that consuming fibre can help to keep blood sugar and insulin levels low (16, 17, 18). Although the cause is not yet clear, insoluble fibres have been found to be inked to a reduction in the blood sugar levels and also a decreased risk of diabetes development (19, 20).


5. Minimise Intake Of Processed Foods

Processed foods are linked to all kinds of health problems, which include heart disease, obesity and diabetes. Studies have suggested that by cutting back on processed foods which are high in vegetable oils, refined grains and additives could be key to reducing the risk and onset of diabetes (21, 22).

Further studies also suggest that poor quality diets which are high in processed foods can increase the risk of diabetes by almost thirty percent – however by including nutritious whole foods, this risk can be reduced (23).
