Staying health isn't just about what you eat but also when you eat. According to a new study published in Cancer Epidemiology, Biomarkers & Prevention shows that eating late at night could actually raise your risk of breast cancer. Researchers in California found that simply eating meals at set times and dining early in the evening reduced women’s risk of developing breast cancer. The reason behind this? When you eat, your body breaks down the sugars and starches into glucose, which enters the bloodstream. Glucose is then ushered by insulin to your cells, where it can be used for energy. However, when your body doesn’t produce enough insulin, your blood sugar builds up and your levels stay high—something that a number of studies have linked to an increased risk of breast cancer. The study found that women who left more time between their last snack of the day and first meal of the next morning had much better control over their blood sugar levels. In fact, for every three additional hours participants went without eating overnight, their blood glucose levels were four percent lower. This benefit was regardless of how much the women ate at their last or first meal. The ideal time to eat breakfast to keep your metabolism working overtime is within 90 minutes of waking up - so aim to eat nothing between the 2 hours prior to your slumber.
