This is an interesting question and something that I come across quite often as a personal trainer. As a personal trainer and someone who has lost a lot of weight, there are certain things that I know and certain things I don't. When it comes to things like wheat or gluten however I am a big fan of test and measure.
What I mean by test and measure is that I am firm believer in testing small things when it comes to diet and seeing how people get on with them. Gluten, which is the protein in wheat, is one of things that a lot of the human population are very sensitive to and perhaps don't realise it. That's why a lot of foods say "contains gluten" on the back of the packet.
The fact that a lot of people potentially have gluten intolerance really doesn't fit in with the modern diet which is composed mostly of grains and bread in particular. Have you ever noticed how we are conditioned to believe that bread must the corner stone of any diet? If you think about breakfast, normally it is either a wheat based cereal or toast that we automatically assume to be "normal" I am a very big believer in challenging these preconceived ideas.
In truth the only people qualified to discuss dietary specifics are Doctors and nutritionists but I would certainly say if you suffer from bloating, gas or indigestion, in my experience, a doctor is more concerned with cure rather than prevention. On the weight loss side I have seen massive changes when things like bread have been cut out of peoples diets, the good thing is that I have never seen any research that states that bread or wheat are essential to the human diet. The only thing that does this is the food pyramid (which is produced by government agencies who receive "contributions" from large companies who produce sugar based products) which bears no resemblance to the food we consumed for millions of years prior to the agricultural revolution.
So, when it comes to test and measure, I would certainly advise anyone to try either reducing the amount of bread they eat on a daily basis or cutting it out altogether for a week or two and seeing how they feel. This also inspires creativity, particularly at breakfast time when it is easy to have cereals and milk or toast and jam. Of course, specific concerns should always been discussed with a doctor but small adjustments like reducing bread intake may mean massive improvements in energy levels, reduction in weight and even better digestion.
