WHY TO LIMIT IT ON KETO
- Not recommended: ~15.9g net carbs per 100g exceeds typical keto targets
- High natural sugars with relatively low fiber
- Minimal fat/protein → poor satiety per carb
- Quick glucose/fructose load can disrupt ketosis
- Small serving size before hitting carb limits
- Fructose is primarily processed in the liver—unfavorable for keto
HEALTH BENEFITS
- Contains resveratrol, associated with cardiometabolic support
- Anthocyanins provide antioxidant and anti-inflammatory activity
- Supplies quercetin and other polyphenols that support vascular health
- Provides potassium and small amounts of vitamin C
- Hydrating, water-rich fruit for rare, mindful indulgences
- Whole-fruit matrix offers more fiber and phytonutrients than juice
PREPARATION SUGGESTIONS
VERY SMALL PORTION
Limit to ~4–6 grapes (≈20–30g) and pair with cheese or nuts to slow absorption.
FROZEN RARE TREAT
Freeze 5–8 grapes for an occasional sweet bite; count carbs carefully.
WINE ALTERNATIVE
Drop 2–3 halved grapes into sparkling-water for a light grape accent.
SALAD ACCENT
Add 4–6 thin slices to a large salad with fatty dressing and protein.
CHEESE COURSE
Include 3–5 grapes alongside cheddar-cheese and walnuts; pre-portion.
