Here is a summary of the passage:

Chili peppers, or chiles, contain a chemical called capsaicin. That chemical is what makes chiles seem hot. Receptors in our mouths sense capsaicin. The same receptors tell us when foods like pizza are too hot to eat. I don't like spicy foods, but I do like to eat pizza. You can find the best pizza in Italy.

No, this is not a good summary of the passage. The summary should capture the main points and ideas of the passage, but this summary only focuses on one aspect, which is the presence of capsaicin in chili peppers and its effect on the perception of spiciness. It does not mention the receptors in our mouth that sense capsaicin or the comparison to pizza being too hot to eat. Additionally, the last sentence about finding the best pizza in Italy is unrelated to the main topic of the passage and seems like an unrelated statement.
