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.

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.
