Cider vinegar has 21 kcal per 100 g – negligible in a food log. Vinegar before a carb-rich meal reduces post-meal glucose by a meaningful margin (Shishehbor et al., Diabetes Res Clin Pract 2017; SMD −0.60). The acetic acid slows gastric emptying, blunting the glucose spike. No need to weigh – the calorie impact is near zero.
How should I track Vinegar, cider?
Small amounts of Vinegar, cider add up faster than most people realize. A systematic review (Whitton et al., Adv Nutr 2022) found that condiments are among the most frequently omitted items in food logs — skipped 1–80% of the time. A tablespoon of mayo or dressing can add 50–100 calories, and most people use two or three tablespoons without measuring. The fix is simple: keep a teaspoon or scale near your plate and measure once. Sauces and dressings are often the hidden reason a "healthy" salad ends up at 600+ calories.
