The science of food and glucose, explained simply.

Do Sweet Potatoes Spike Your Blood Sugar?

Sweet potatoes have a moderate glycemic index (GI 44–94) that varies dramatically by variety and cooking method. Boiled sweet potatoes (GI 44) spike far less than baked (GI 94).

Do Tomatoes Spike Your Blood Sugar?

Tomatoes have a very low glycemic index (GI 15) and contain only 3.2g of sugar per medium tomato. They are one of the most blood sugar-friendly foods available.

Does Agave Spike Your Blood Sugar?

Agave nectar has a low glycemic index (GI 15–30) because it is 75–90% fructose. But high fructose consumption promotes liver fat, insulin resistance, and metabolic syndrome.

Does Alcohol Affect Your Blood Sugar?

Alcohol has a complex effect on blood sugar — it can both spike it (from mixers and beer) and crash it (by blocking liver glucose production). The combination can be dangerous.

Does Alcohol Spike Your Blood Sugar?

Alcohol has a complex effect on blood sugar: it can cause both spikes and dangerous drops. Beer (GI 66) spikes, while wine and spirits have minimal direct glucose impact.

Does Almond Milk Spike Your Blood Sugar?

Unsweetened almond milk has a GI near 0 and contains less than 1g of sugar per cup. It is one of the most blood sugar-friendly milk alternatives available.

Does Apple Cider Vinegar Lower Blood Sugar?

Apple cider vinegar can reduce blood sugar spikes by 20–35% when consumed before or with a carb-rich meal. The acetic acid slows gastric emptying and inhibits starch digestion.

Does Avocado Affect Your Blood Sugar?

Avocado has virtually no effect on blood sugar. A whole avocado contains less than 4 grams of net carbs and has a glycemic index near 0. Avocado eaten with carbs reduces the spike by 20–30%.

Does Beer Spike Your Blood Sugar?

Beer has a high glycemic index (GI 66–110) and is the most glucose-spiking alcoholic drink. A pint of regular beer delivers 13–20g of carbs, and alcohol blocks the liver's glucose regulation.

Does Bread Spike Your Blood Sugar?

White bread (GI 75) is one of the fastest-spiking common foods. Sourdough (GI 54) and whole grain bread (GI 51) spike significantly less due to intact structure and organic acids.
