1. That's assuming that the grape skin cannot be dissolved by stomach acids. I highly doubt this.
2. That is also assuming it isn't like corn (maize). Corn appears whole, but it isn't: We extract carbs from it and let the bits we cannot digest pass through. It is the same process when you find "pills" in your poop.
- refurb 6y agoYour stomach acid isn't that strong, only 1M HCl. Grape skins are made up of complex carbohydrates, which our bodies don't digest, bacteria in our large intestine break it down (somewhat). That concentration of acid will breakdown complex carbohydrates if exposed for a long time, but our stomachs empty in 1-4 hours. I don't disagree that your body could extract some of it. The grape has a tear in the skin at the top, but compared to chewing? Very little is absorbed.
