Plain Kefir with Banana — AgeGen

200 ml of plain kefir with half a banana — 200 kcal, 10 g of protein, and at least 10⁹ live cultures — a two-ingredient snack that pairs probiotic bacteria with prebiotic fibre to feed the gut microbiome between meals.

Ingredients (1 serving)

  • Plain kefir (full-fat or low-fat) — 200 ml
  • Banana — ½ medium (60 g)

Macros per serving

  • Calories: 200 kcal
  • Protein: 10 g
  • Fat: 5 g
  • Carbs: 30 g
  • Fiber: 2 g

Key micronutrients

  • Probiotics: ≥10⁹ CFU (live active cultures — verify on label)
  • Calcium: ~240 mg (~24% of daily value)
  • Potassium: ~500 mg (~11% of daily value)
  • Vitamin B12: ~0.8 µg (~33% of daily value)

Why it earns a spot in the rotation

  • Synbiotic pairing. Kefir delivers live bacteria; banana's fructooligosaccharides and resistant starch act as prebiotic fuel for those bacteria. Consuming both together is a practical synbiotic approach that food-based research supports for gut-microbiome diversity.
  • Broader strain diversity than yogurt. Kefir is fermented with a mixed culture of bacteria and yeast (20–30 strains in traditional versions versus 2 in most yogurts), which research associates with greater microbiome impact.
  • Potassium from banana. Half a banana contributes roughly 11% of the daily potassium target — relevant for blood-pressure and fluid-balance goals.
  • Zero preparation. Pour and peel. The snack takes under one minute and travels easily in any container.
