I agree with this--but I think the distinction that needs to be made is
when we let people know about foods, we must also let them know about risks
or problems. That is NOT to say one never eats sugar or red meat or uses
cooking oil, short of making a choice to do so. And there ARE data out
there that support these views if you just look for it (see below).
However, it IS to say that we KNOW that there are risks to such
consumption. What in the world is the problem with that?
As an example: "SuperSize Me" is a movie about a fellow whose wife is a
vegan. He decides to do a documentary and go for one month eating NOTHING
but McDonalds. Morning, noon and night. He vomits the first day, but
otherwise remains relatively stable--except his bloodwork starts to fall
apart and he starts to get fat. Not only does his LDL go up, but his liver
starts to fail. The physician monitoring begs him to stop.
This is an extreme--but I think it underscores the point nicely. Indeed,
the fact that the jury is out on sugar and thrush--well and good. Then that
is PRECISELY what should be written. Not: NEVER eat sugar! That kind of
"just say no" approach is pretty unlikely to have any benefit.
But rather something along the lines of--"using unrefined sugar may cause
health problems for some people. Anecdotally, some people in the community
have noticed increased problems with thrush when eating too much sugar.
Indeed, some clinical data support this view."
And as you say, I think it is also important to include in rigorous,
comprehensive guidelines information such as particular problems when
diarrhea is present, etc. Diarrhea is the thing that is far too likely to
kill people and it need not ever.
As to cooking oil--well, of course that depends on the variety being used.
Foods are health and life...but too much or the wrong kinds can damage
health. I really don't understand why this is an issue?
In any event--I think the absolute BEST guidelines will come from
discussions with people living with HIV/AIDS sharing their experiences!
This kind of sharing worked to help reduce the incidence of HIV in Uganda
and it can help improve nutrition for all people.

carbohydrates on the in vitro epithelial adhesion of Candida albicans,
Candida tropicalis, and Candida krusei. New Microbiol. 2000 Jan;23(1):63-71.

Adhesion to epithelial surfaces is considered as a critical step in the
pathogenesis of oral candidosis. Therefore, the effects of the most
commonly consumed dietary carbohydrates on the adhesion of Candida
albicans, Candida tropicalis, and Candida krusei to monolayered HeLa cells
were investigated. Adherence of C. albicans and C. tropicalis appeared
significantly promoted by incubation in defined medium containing a high
concentration (500 mM) of fructose, glucose, maltose, and sucrose (p <
0.001). C. albicans organisms grown in sucrose elicited maximal increase in
adhesion, whereas adhesion of C. tropicalis and C. krusei was enhanced to
the greatest extent when cultured in glucose. Maltose and fructose also
promoted adherence of C. albicans and C. tropicalis (p < 0.001), but to a
lesser extent than sucrose and glucose. On the other hand, sorbitol-grown
yeasts demonstrated a marginal increase in adhesion (p > 0.01). Xylitol
only significantly reduced adherence of C. albicans (p < 0.001). These
results suggest that the frequent consumption of carbohydrates, such as
sucrose, glucose, maltose, or fructose, might represent a risk factor for
oral candidosis. The limitation of their consumption by substituting
xylitol or sorbitol could be of value in the control of oral Candida
colonization and infection.
