Myth Busters
MYTH #1: Kefir and Yogurt Are Basically the Same
TRUTH: Kefir contains 14 live cultures compared to yogurt's typical 2-7 strains. Kefir also includes beneficial yeasts and bacteria strains not found in yogurt, providing broader gut microbiome support and better colonization of the intestinal tract.
MYTH #2: Kefir Is Too High in Calories for Weight Loss
TRUTH: Tesco Gut Sense Kefir has only 55 calories per 100ml. The combination of protein (3.6g) and probiotics supports healthy weight management through improved gut microbiome diversity and increased satiety.
MYTH #3: Kefir Causes Bloating and Digestive Issues
TRUTH: Initial consumption may cause mild bloating as gut bacteria adjust, but this typically resolves within 1-2 weeks. Long-term kefir consumption actually reduces digestive discomfort by improving microbial balance and reducing harmful bacteria.
MYTH #4: Pasteurised Kefir Has No Live Cultures
TRUTH: Tesco Gut Sense Kefir is fermented after pasteurisation, meaning the live cultures are added and remain active. The product contains 14 verified live kefir culture strains. Always check the label confirms "live cultures" for probiotic benefits.
MYTH #5: Kefir Is Only for People with Gut Problems
TRUTH: Probiotics support immune function, nutrient absorption, and mental well-being in healthy individuals too. Regular kefir consumption helps maintain gut barrier integrity, produce short-chain fatty acids, and support overall metabolic health.

How to Flatten the Spike
Kefir's protein and fat content naturally slow glucose absorption, but you can optimize further:
- 🥣 With oats or granola - Adds fiber to slow carb absorption even more
- 🥜 With a handful of nuts - Extra healthy fats and protein for sustained energy
- 🫐 With berries - Low-GI fruit adds antioxidants without spiking sugar
- 🥚 After a protein-rich meal - Consume kefir as a dessert drink for minimal glucose impact
This combination not only keeps blood sugar stable but also maximizes probiotic absorption and gut health benefits.
