11 'Sugar-Free' Traps: Foods That Still Spike Blood Glucose Levels
9. Canned Soups

Canned soups may boast “no added sugar,” but they’re rarely blood sugar-friendly. Most commercial soups are thickened with flour, potatoes, or corn starch—carbohydrates that break down quickly and spike glucose. Even brothy soups can contain hidden noodles, legumes, or rice in portions large enough to impact your levels. Plus, these products often lack fiber or fat to slow digestion, making them fast-acting glycemic traps. If you’re managing insulin sensitivity, look beyond the sugar content and consider the full carb profile. Homemade soups or carefully selected brands with whole ingredients and no starches are your best bet.
