1. Most dietary organizations have become corrupted by junk food companies and big pharma. Many high profile dietitians are in receipt of payment from at best dubious companies. Check out some of the largest organizations advising Governments on diet, and what I call conflicts of interests are paying the bills and pulling the strings. So corrupt and tainted has the situation got in the US, that a group of dietitians has broken away from the Academy of Nutrition and Dietetics, the equivalent of the British Dietetic Association and formed Dietitians for Professional Integrity.
2. So many doctors and dietitians have become so entrenched in what they like to call "evidenced based" science. It is now becoming clear, that much of the so-called evidence has become out-dated, and never was based on true and honest science.
3. A great quote sums up the situation for many healthcare professionals “It is difficult to get a man to understand something, when his salary depends on his not understanding it.” Upton Sinclair.
Changes have to be made, and are being made. The number of informed and clear thinking doctors, scientists and dietitians grows by the day, who have become converts to the low carb cause. Not only for their patients, but also for themselves. Money and corruption has played a big hand in the epidemics of obesity, and the often linked type two diabetes. Ironically, money, or more accurately the lack of money will end the madness. Health systems all over the world are being bankrupted by the aforementioned epidemics, the financial cost grows by the day. The cost in human misery is incalculable.
