The science of food and glucose, explained simply.
Does Green Tea Lower Your Blood Sugar?
Green tea may modestly reduce fasting blood sugar by 5-10 mg/dL. The catechin EGCG inhibits starch digestion and may improve insulin sensitivity, but the effect is small.
Does Honey Spike Your Blood Sugar?
Honey has a glycemic index of 45–64 depending on type. Raw honey spikes less than processed, but still delivers 17g of sugar per tablespoon.
Does Hummus Spike Your Blood Sugar?
Hummus has a low glycemic index (GI 6–28) due to its chickpea base, tahini fat, and olive oil. A typical serving of 2 tablespoons contains only 3g of net carbs.
Does Ice Cream Spike Your Blood Sugar?
Ice cream has a surprisingly moderate glycemic index (GI 36–62) because its high fat content slows digestion. But it delivers 20–30g of sugar per serving in a delayed, prolonged spike.
Does Juice Spike Your Blood Sugar?
Fruit juice spikes blood sugar as much as soda. Orange juice (GI 50) delivers 26g of sugar per cup with no fiber to slow absorption. Whole fruit is dramatically better.
Does Mango Spike Your Blood Sugar?
Mango has a moderate glycemic index (GI 51–60) and contains 22g of sugar per cup. It spikes more than berries but less than pineapple or watermelon.
Does Maple Syrup Spike Your Blood Sugar?
Maple syrup has a glycemic index of 54 — lower than table sugar (GI 65) and honey (GI 58). But it still delivers 13g of sugar per tablespoon.
Does Meal Timing Affect Your Blood Sugar?
Meal timing significantly affects blood sugar. The same meal eaten at 8pm spikes 17-44% more than at 8am. Eating carbs last, not first, reduces spikes by 30-40%.
Does Milk Spike Your Blood Sugar?
Milk has a low glycemic index (GI 31–39) and causes a small blood sugar spike. But milk triggers a disproportionately large insulin response — 3–6x what its glucose impact would predict.
Does Oatmeal Spike Your Blood Sugar?
Oatmeal can spike blood sugar depending on the type — instant oats (GI 79) spike fast, while steel-cut oats (GI 42) produce a much slower, smaller response.
