Differences between wine grapes grains and table grape grains, is mostly selection and cultural practices. Table grape is grown for volume and freshness, wine grape is grown to be concentrated in sugar and other compounds, with lower yields, higher maturity, etc.
Both use lots of pesticides nowadays unfortunately.
As for their capability of sustaining life, I don’t know. Grape was used for fasting and purging traditionally :)
