SERVING SIZE
Calories by portion and serving weight
Words such as “small,” “medium,” “half” and “one piece” are convenient but imprecise. Grams make the estimate reproducible, particularly when natural foods vary in size.
MACROS
Carbohydrate, protein and fat explained
Protein

Fibre, vitamins and minerals
One food does not need to provide every nutrient. These are the characteristics most useful for understanding where grapes fits in a varied eating pattern.
Potassium
191 mg per 100 g in the selected USDA record.
Vitamin K
14.6 µg per 100 g in the selected USDA record.
Calcium

FOOD STATE MATTERS
How preparation changes the nutrition estimate
A reliable calorie entry should describe the food you actually ate—not merely a food with a similar name.
Red or green, raw
Selected generic reference.
Muscadine or slip-skin
Use the variety-specific mapped record.
Canned
Match water or syrup pack and include liquid as eaten.
Raisins or juice
Use the dried-fruit or juice record rather than raw grapes.
PRACTICAL CONTEXT
How grapes can fit different goals
There is no universal “good” or “bad” food. Portion, frequency, the rest of the meal, preferences and individual health needs all matter.
Portion math
At 69 kcal per 100 g, the 49 g example is 33.8 kcal.
Fibre check
The selected record lists 0.9 g fibre per 100 g.
Protein check
The selected record lists 0.72 g protein per 100 g.
Best logging move
Weigh the edible grapes and switch records for canned, dried or juiced forms.
QUALITY & SAFETY
How to choose, store and prepare it
Store
Keep grapes dry and chilled.
After opening or cutting
Rinse shortly before eating and drain well.
Prepare
Remove mouldy or leaking grapes from the bunch.
Safety boundary
The nutrient record does not establish storage duration; follow current produce-safety guidance.
PHOTO LOGGING
How to log grapes more accurately
A food photo can suggest the ingredient, but it cannot always reveal exact weight, hidden oil or preparation details. These checks turn an image guess into a better estimate.
- 01
Match the exact reference state: Grapes, red or green (European type, such as Thompson seedless), raw.
- 02
Use edible grams. Calories are scaled from the selected per-100-g record; named portion weights come from the same local USDA record.
- 03
Log oil, sauce, sweetener, salt and recipe ingredients separately.
- 04
Use a separate record when preparation changes the food state.
