Green grapes are not suitable for keto with ~17g net carbs per 100g. Their high sugar content makes them one of the higher-carb fruits. A very small portion (≈20–30g, ~3–5 grapes) might fit flexible carb cycling, but they’re best avoided on standard keto.

WHY TO LIMIT IT ON KETO
- Not recommended: ~17g net carbs per 100g is too high for most keto diets
- High sugar density: nearly all carbs are simple sugars, not fiber
- Low satiety: minimal fat/protein hampers appetite control
- Easy to overeat: bite-size portions make carb creep likely
- Modest fiber (1.6g/100g) offers limited offset
- Rapid glucose impact can disrupt ketosis
HEALTH BENEFITS
- Contains resveratrol supporting cardiovascular health
- Rich in flavonoids and polyphenols with anti-inflammatory activity
- Provides vitamin K for bone and heart health
- Includes quercetin which may support immune function
- Supplies manganese for bone development and metabolism
- Neuroprotective polyphenols may support brain health
PREPARATION SUGGESTIONS
TINY PORTION
Limit to ~3–5 grapes (≈20–30g) and pair with nuts or cheese to blunt glycemic impact.
FROZEN TREAT
Freeze 3–5 grapes for a rare, cold treat—keep portions very small.
CHEESE PLATE ACCENT
Add 3–5 grapes alongside aged cheeses, olives, and nuts for balance.
SPARKLING WATER TWIST
Muddle 1–2 grapes in sparkling-water with ice and a drop of stevia for light flavor.
