Refined Carbohydrates and Flours

Refined carbohydrates and flours, which are abundant in white bread, pasta, and pastries, have a high glycemic index. This means they can cause spikes in blood sugar levels, which have been linked to an increased risk of cancer, particularly breast cancer. These foods are also low in essential nutrients and can contribute to obesity, another cancer risk factor.

Incorporating whole grains into your diet, which are higher in fiber and have a lower glycemic index, can be a healthier alternative. Foods like whole wheat bread, brown rice, and quinoa are not only nutritious but also help in maintaining stable blood sugar levels.
