[3] He claimed that fruits and vegetables produced alkaline 'end-products' when they were metabolized, while processed and refined foods resulted in acidic 'end-products' after digestion.

The Hay diet was popular in the 1930s and many restaurants offered 'Hay-friendly' menus; followers of his dietary advice, included Henry Ford[6] and Man Ray.
