It's Australian Open time and for tennis tragics that means some late nights. Dominating mens tennis at the moment is Novak Djokovic, and his domination over Rafael Nadal has coincided with eating gluten free! Well, maybe this is not the only reason but it sure has made a great difference.
In 2010 it was suggested to Novak that he may be sensitive/allergic to gluten - the protein that is found in wheat, rye, oats and barley. His professionalism and goals to perform his best led him to dramatically change his diet.
Gluten is a protein that humanity is now eating much more. And we are breeding strains of wheat that have a higher content of this protein. While it may be better from a chef's perspective to have more "stickiness" to our breads and doughs, and help make naan bread taste more delicious, it is seriously affecting the health of some individuals. It is thought that there is about 1% of the population with the more serious coeliac disease, and many more who are actually sensitive to the protein and generally feel much healthier without it.
