In an age where fast food joints and sugary treats seem to be around every corner, it’s no surprise that prediabetes is on the rise. A study published by the WebMD website shows in the year 2018, over 70% of patients diagnosed with diabetes and prediabetes were due to wrong food choices. Prediabetes is a critical juncture, a warning signal from your body that your sugar levels are higher than they should be. But haven’t yet reached the threshold for a diabetes diagnosis. The good news is that prediabetes is often reversible with the right lifestyle changes, and one of the most effective ways to take control of your health is through your diet. In this article, we’ll explore the top prediabetes foods to avoid, shedding light on the dietary choices that can make all the difference in preventing the progression to full-blown diabetes. Whether you’ve been recently diagnosed with prediabetes or simply want to reduce your risk, understanding these foods to avoid when pre diabetic is a crucial first step towards better health.

1. Refined Carbs

Alternative of Refined Carbs In Prediabetes:

Refined carbohydrates top the list of prediabetes foods to avoid. They are a key concern for individuals with prediabetes due to their damaging impact on blood sugar control. According to a study published in the National Library of Medicine, refined carbs heighten the risk of type 2 diabetes from prediabetes. These refined or simple carbs, found in items like white bread, sugary cereals, and white flour products, are swiftly converted into glucose in the body. This conversion leads to rapid spikes in your sugar levels. This is a problem heightened by the already compromised blood sugar levels in prediabetes. There, they are first on our list of borderline diabetic foods to avoid.

Furthermore, long-term consumption of refined carbs can foster insulin resistance. In this, your body cells become less responsive to insulin’s glucose-regulating effects. This condition deepens the prediabetic state and increases the risk of developing type 2 diabetes.

Weight management is another issue. Refined carbs are often calorie-dense but lacking in nutrients and fiber, promoting overeating and weight gain—another risk factor for prediabetes and diabetes. Moreover, these carbs fail to provide lasting fullness, encouraging excessive snacking and calorie intake.

Although daily prediabetes sugar consumption has no exact recommendation, the upper limit should be less than 25 grams or 6 teaspoons for women. And for men, it is less than 36 grams or 9 teaspoons per day. According to the Harvard School of Health, replacing just one serving of sugary beverages lessens the chances of diabetes by 2-8%.

4. Saturated Fats

Saturated fats are another borderline diabetic foods to avoid. They are discouraged for prediabetes patients due to their adverse effects on health. These fats can exacerbate insulin resistance, a hallmark of prediabetes, making it harder for the body to regulate blood sugar levels. They also promote inflammation, which is linked to insulin resistance. And a heightened risk of developing full-scale type 2 diabetes.

Moreover, studies by the NIH (National Institute of Health) show saturated fats can harm heart health by increasing LDL cholesterol, a risk factor for heart ailments. Heart diseases are a common complication of diabetes. Their calorie density can contribute to weight gain, which, in turn, worsens insulin resistance and increases the risk of prediabetes progression.

A diet high in saturated fats often displaces healthier choices like fruits, veggies, and whole beans and grains. This results in a less balanced and nutritious eating pattern. To manage prediabetes effectively, it’s wise to limit saturated fat intake by reducing consumption of sources like fatty meats and full-fat dairy products.

Alternative of Dairy Products in Prediabetes:

Dairy products are also foods to avoid with borderline diabetes or prediabetes. According to a study published in the NLB(National Library of Medicine), dairy products like milk and its related items contain IGF molecules (Insulin-Like Growth factors). These IGF molecules appear as insulin to your body, and thus, it reduces insulin production. Although IGF molecules may appear like insulin, they don’t function like it at all. With insulin secretion minimised, the blood sugar levels automatically increase. Therefore, dairy products are foods to avoid if prediabetes is diagnosed.

Top starchy veggies are potato and sweet potato and their related products. According to the diabetes.co.uk website, starchy veggies raise blood sugar more abruptly. Potatoes have a high GI score. This is due to their high carb content. Consumption of these veggies can lead to a rapid rise in blood sugar and insulin production.
