NOBODY.
Health food companies sell products that are accompanied by information about food in general that appears to be adjusted to make the products appear more valuable. Every time I try to better my diet, I do a little research online and the more I look, the more conflicting information I find.
This kind of nutritional disinformation is criminal, Nobody seems to agree on anything and it leads me to the conclusion that disinformation about food is published to be congruent with the actual product being offered.
Two companies (Separate or otherwise) that promote the Alkalinity of foods as more healthy that acidic foods, published their own lists of foods categorized by their alkaline and acid content.
Those lists are contradictory.
This first site does not even overtly identify itself. You must read carefully, and some of the language is in Spanish, however, The address is 999 Park Avenue in New York? Highly suspicious in my opinion.
Here is their list of alkaline and acid foods

List of Acid Fruits
"All fruits aside from those listed in the alkaline column."
According to the last statement, most of the fruits on the other company's list of alkaline fruits, are actually acidic. So, who do I believe? I don't know how to get this information from the FDA or USDA, or whether or not alkalinity is really important anyway.
I started eating a lot of Almonds recently and noticed that I was actually sleeping through the night, and feeling a whole lot better. This is what started the whole thing in the first place.
I guess I'll just keep eating more Almonds for now.
