Managing blood sugar is crucial for overall health, especially for those with diabetes or prediabetes. Certain foods can spike blood sugar levels quickly and make control more difficult. Here are 4 foods you should avoid, according to doctors.

1. Watermelon

Although watermelon is refreshing and sweet, it has a high glycemic index. Eating large amounts can cause blood sugar spikes, so it’s best to enjoy in small portions or pair it with protein or fiber.

2. White Bread and Refined Grains

Products like white bread, pastries, and white rice are quickly digested into sugar, leading to rapid increases in blood glucose. Opt for whole grains instead.

3. Sugary Drinks

Sodas, fruit juices, and energy drinks are loaded with sugar and provide almost no nutrients. They can cause sudden blood sugar surges and contribute to insulin resistance.

4. Sweetened Snacks and Desserts

Candy, cakes, and cookies contain refined sugar and fat, making them a double threat for blood sugar and weight management. Healthier alternatives include fruit with nuts or sugar-free treats.
