Upswing: Caffeine
Blood sugar can rise after drinking coffee — even black coffee with zero calories — thanks to the caffeine. Likewise, black tea, green tea, and energy drinks can hinder blood sugar control in people with diabetes. Each person reacts differently, so it’s best to track your own responses to foods and activities. Ironically, other compounds in coffee may help prevent type 2 diabetes in healthy people.
Lower: Household Chores
Cleaning the house or mowing the lawn can have an added bonus for people with diabetes: lower blood sugar. Many of the chores you do around the house count as moderate physical activity, with plenty of health benefits. Make a point of walking around the grocery aisles or parking farther from the entrance to the store. Small amounts of exercise add up.
