Food for thinking?

I read the story in Food and Drink Europe about some of the Delegates at the International Congress of Nutrition protesting at the presence of the big multinational manufacturers of food and drink.
Did they think that the money lenders were trying to get back into the temple? The booboys and girls saw the multinationals as the sources of bad food, the founts of all obesity. Had they leapt out of their box of self-righteousness perhaps they would have seen the event as an opportunity.
The meeting was not only looking at obesity but also at malnutrition and the problems of child development from a poor diet.
Surely this was an opportunity to deliver solutions in clever ways.
Even the ‘do goody’ dieticians should have sat down and talked sensibly with the big brand producers.
The big food and beverage producers have all the resources to source the right ingredients and distribute the products efficiently around the world. They know how to make things tasty and attractive and they, as much as any dietary activist want to help their customers stay healthy and buying more product.
The biggest challenge for the nutritionists would not be persuading the big brands that producing products with a positive impact on health and obesity would be a good idea. The challenge is helping the consumer sort the wheat of good healthy products from the chaff of groundless claims.
Is there a recognized and respected professional body of nutritionists out there to provide some kind of certification or approval ?
Could they look at the ingredient specifications and pronounce  the new wonder product to be “safe, delicious and nutritionally good” to the world?
