I am a researcher doing a survey and study on people's eating habits.

Based on the survey web site, it doesn't appear that way; you appear to be a
sponsored flak for an interest group.

The survey
is attempting to determine if the trend towards a more healthy diet is
actually occuring despite hearing about growing obesity around the
world.

The survey, brief as it is, is so full of undefined terms and inadequate
response choices, as well as a prejudiced presumption favoring a low-meat diet,
that one can easily presume that you aren't seriously interested in analyzing
information but are assembling a mailing list to market something.
