About muscadine grapes

A thick-skinned, seeded grape native to the southeastern United States, tolerant of heat and humidity that kill European vines. The tough skin and seeds carry most of its polyphenols and are usually spat out.

Also known as Muscadine, Scuppernong, Bullace grape

The evidence in depth

Best supported: Insufficient

What each association actually rests on, and the papers behind it. A rating describes the state of the research, not how impressive the food is. How we rate evidence.

Heart Health
Insufficient evidence

A small number of trials have tested muscadine seed or skin extracts and grape wine polyphenols on lipids, with mixed results. Eating the fresh fruit has not been studied, and the amounts of polyphenol involved are not comparable.

Insufficient evidence. Not enough human research to say anything useful yet.

Nutrient values are per 100 g of the USDA reference entry named on this page and vary with variety, growing conditions, storage and preparation.

Source record: Grapes, muscadine, raw (USDA FoodData Central, FDC ID 173040).

% DV uses the FDA Daily Values for adults and children aged 4 and over. A dash means no Daily Value has been established for that nutrient.

Bioactive compounds

Compounds present in meaningful amounts. Presence is banded rather than quantified, because whole-food levels vary enormously with variety, growing conditions, storage and preparation.

How preparation changes things

Only effects with real support are listed. If a preparation method is missing, it is because nothing dependable is documented — not because it makes no difference.

Nothing dependable is recorded about how preparation changes this food’s nutritional properties. Rather than guess, this section stays empty.

Things to know

Allergies, interactions and intake concerns. Every food gets this section — a reference where everything is uniformly good is not a reference.

  • Worth knowing

    Most of the polyphenol content is discarded

    The compounds muscadine is celebrated for sit in the skin and seeds, which the usual way of eating the fruit removes. Extract studies are therefore measuring something quite different from eating grapes.

  • Worth knowing

    Choking hazard for young children

    Muscadines are large, round and firm-skinned, which makes them a particularly poor shape for small airways. Cutting them lengthways is the standard precaution.
