Is the noble Hadith, "Do not let the last of your food be water," authentic, and is it permissible to add a small bite after drinking water to avoid water being the last of one's food?

The aforementioned Hadith, "Do not make water the last thing you consume," has no basis, and there is no اعتبار (value/reliance) in what it states. The reference for this matter is to the specialists among physicians.
