About Grape
Noticeably sweet; good for fruit-calorie comparison.
Health Benefits of Grape
Rich source of polyphenols
Grapes are a key source of resveratrol and proanthocyanidins. These concentrate in the skin and seeds, and red/purple grapes hold far more than green ones. 'Don't spit the skin' has a basis - over 70% of the grape's antioxidants are in the skin.
Glucose and fructose; fast absorption
Grapes' sweetness comes from the monosaccharides glucose and fructose, absorbed directly without digestion. Sugar varies by variety: Kyoho is very sweet (~15% sugar); muscat grapes add aroma. Raisins concentrate sugar ~8x - calories jump from 43 to 341 kcal/100g, so watch portions.
Fresh eating vs wine - same source, different calories
Fresh grapes are moderate (~43 kcal/100g), while wine's calories come mostly from alcohol, not sugar - a 150ml glass of red wine is ~108 kcal. Grape juice is ~50-60 kcal/100g but loses most pectin and fibre once the skin is removed. Eating whole grapes is the most complete way.
