Pre-Diabetic Diet: What You Need To Know

what is a pre diabetic diet

Prediabetes is a term introduced by the American Diabetes Association to identify those at risk of developing type 2 diabetes. Prediabetes is characterised by higher-than-normal blood sugar levels, which, if left untreated, can lead to diabetes and other serious health issues. However, a prediabetes diagnosis does not guarantee the development of diabetes. A healthy, well-balanced diet, physical activity, and weight loss can help to lower the risk of developing type 2 diabetes. This paragraph will discuss the dietary changes that can be made to reduce the risk of developing type 2 diabetes.

The Mediterranean diet

Prediabetes is a condition where your blood sugar levels are higher than they should be, but not high enough to be classified as Type 2 diabetes. A prediabetes diagnosis does not mean that you will develop Type 2 diabetes, and healthy lifestyle changes can help to reverse the diagnosis.

  • Breakfast: Greek yogurt with a peach, a medium banana, and 30g of plain almonds
  • Mid-morning snack: Apple slices with crunchy peanut butter
  • Lunch: Two oatcakes with cottage cheese, cucumber, and an orange
  • Afternoon snack: Warm exotic fruit salad with Greek yogurt, 50g of cottage cheese, 80g of cherry tomatoes, and 30g of pumpkin seeds
  • Dinner: A Mediterranean diet recipe that includes whole grains, lean protein, and healthy fats, such as chicken, eggs, or fish, with a side of vegetables

It is important to note that everyone is different, and you should tailor your food plan to your individual needs. Working with a doctor or dietitian can be helpful in creating a plan that is right for you.

Weight loss and physical activity

To achieve and maintain a healthy weight, it is recommended to adopt a well-balanced diet that includes a variety of nutritious foods. This involves incorporating more fruits, vegetables, whole grains, lean protein, and healthy fats into your meals while reducing the consumption of starchy and sugary foods. The Mediterranean diet is often recommended for people with prediabetes due to its emphasis on whole grains, lean protein, and healthy fats. Other dietary approaches, such as the DASH (Dietary Approaches to Stop Hypertension) diet, a plant-based diet, or intermittent fasting, can also be explored, tailoring the approach to individual preferences and lifestyles.

In addition to dietary modifications, increasing physical activity is crucial. Aiming for at least 150 minutes per week of moderate to vigorous exercise or achieving 10,000 steps daily can be a good starting point. It is always advisable to consult with a healthcare professional before starting a new exercise routine. Combining physical activity with a healthy diet can help individuals with prediabetes not only reduce their risk of developing Type 2 diabetes but also improve their overall health and quality of life.

It is important to note that prediabetes is a warning sign indicating an increased risk of progressing to Type 2 diabetes. However, it also presents an opportunity for intervention and positive lifestyle changes. By taking control of their weight and engaging in regular physical activity, individuals with prediabetes can significantly influence their health outcomes and work towards preventing or delaying the onset of Type 2 diabetes.

Small changes, such as reading nutrition labels, reducing portion sizes, and incorporating more physical activity into daily routines, can make a significant difference in managing prediabetes and lowering the risk of associated health complications.

Carbohydrates, fats, protein, and fibre

Carbohydrates

Carbohydrates are a type of macronutrient found in a wide variety of foods, including starches, sugars, fibre, and cellulose. Carbohydrates are important for energy and proper organ function, but they can also cause a spike in blood sugar levels, which is a concern for those with pre-diabetes or diabetes. It is important to be mindful of carbohydrate intake and to focus on complex carbohydrates, such as those found in fibre-rich foods.

Fibre

Fibre is a type of carbohydrate that is essential for overall health and can be particularly beneficial for those with pre-diabetes or diabetes. Fibre helps with blood sugar control, weight management, and can lower the risk of heart disease and certain cancers. The recommended daily fibre intake for adults is between 22 and 34 grams, depending on age and sex. It is important to increase fibre intake gradually to avoid digestive discomfort and to ensure adequate hydration to aid fibre's function in the body.

Fibre-rich foods include:

  • Whole grains: brown rice, quinoa, whole wheat pasta, and bread with whole grain flour listed as the first ingredient.
  • Non-starchy vegetables: spinach, broccoli, and other frozen vegetables.
  • Legumes: lentils, peas, beans (pinto, kidney, lima, navy, garbanzo), and chickpeas. These can be added to meals or pureed for dips and spreads.
  • Fruits, vegetables, nuts, and seeds.

Fats

When it comes to fats, it is important to focus on healthy, unsaturated fats, such as those found in avocados, nuts, olive oil, and fatty fish like salmon. These types of fats can help promote heart health and reduce inflammation in the body. It is recommended to limit saturated fats and avoid trans fats, as these can contribute to insulin resistance and increase the risk of heart disease.

Protein

Incorporating lean protein sources into your diet can help with blood sugar management and weight control. Choose lean meats, poultry, and fish, as well as plant-based protein sources like beans, lentils, and quinoa. These foods can help increase satiety and stabilize blood sugar levels.

Blood sugar and glycaemic index (GI)

The Glycemic Index (GI) is a measure of how quickly a food can make your blood sugar (glucose) rise. It is a relative ranking of how different carbohydrates affect blood sugar. The GI scale goes from 0 to 100, with pure glucose rated at 100. Foods with a higher GI value are more likely to spike your blood sugar than foods with a lower GI. Foods such as oils, fats, and meats do not have a GI, though in people with diabetes, they can affect blood sugar.

Low GI foods increase glucose slowly in your body. Eating low GI foods can help you gain tighter control over your blood sugar. The GI of a food, and its impact on people with diabetes, may change when you combine it with other foods. For example, eating an apple on its own may result in a different blood glucose response than if you ate it with some peanut butter. Combining a low GI food with a high GI food will get you an intermediate GI for that meal.

The amount of the carbohydrate-containing food you eat also affects your blood glucose levels. Even though pasta has a low GI, a large serving can still cause blood glucose levels to rise more rapidly than a smaller serving. This is what is called the glycaemic load (GL). GL considers both the GI of the food and the amount of carbohydrate in a portion. GL can be calculated using the formula: GI x the amount of carbohydrates (in grams) in a serving of food) ÷ 100.

While following the principles of low-GI eating is likely to be beneficial for people with diabetes, reaching and staying at a healthy weight is more important for blood sugar and overall health. Eating to manage your diabetes isn’t just about GI ratings. It's important to think about the balance of your meals, which should be low in saturated fat, salt and sugar and contain more fruit and vegetables, wholegrains, pulses, nuts and oily fish.

Artificial sweeteners

A pre-diabetic diet should aim to reduce blood sugar levels and lower the risk of developing type 2 diabetes. While there is no one-size-fits-all diet for pre-diabetes, a well-balanced and nutritious diet, along with regular exercise, can help manage blood sugar levels and prevent the progression to diabetes.

The effect of artificial sweeteners on people with prediabetes is still uncertain. While they can help reduce sugar intake, they may also negatively impact blood sugar levels, insulin response, and overall health. Some research suggests that artificial sweeteners may even increase the risk of developing diabetes or worsen existing conditions. Like sugar, artificial sweeteners can be addictive, leading to increased cravings for sweet foods.

Some approved artificial sweeteners include Acesulfame potassium (ace-K), Advantame, Aspartame, Neotame, Saccharin, and Sucralose. However, it is important to consult a doctor or dietitian about the safe consumption of these sweeteners.

Instead of relying on artificial sweeteners, it is recommended to opt for natural alternatives like stevia, monk fruit extract, or date sugar. These options have been found to have antidiabetic properties and can help stabilize blood sugar levels. Ultimately, the key to managing prediabetes is adopting a well-balanced diet, staying active, and maintaining a healthy weight.
