the human body is influenced by many things + getting it right is not EZE' Dr Willian Davis a cardiologist notes in his Wheat Belly that his mom died using what todays Drs are taught, he then started searching to do better + notes his patients did well cutting ALL modern grains + going lo carb while eating good quality fats!! he has lots of good info on his blog free + only $16 yearly allows unlimited reading as he debunks modern medicine driven by $$$$!!. the benefits of low carb are well noted many places, BUT i never seen some of his beliefs as well as how he exposes the poor practices used today for big profits. myself can believe more from someone that is not making $$$ from unhealthy people. there are many tests not usually done that can predict your real health or not IMO + of many nutritionalist. thanks for the Jim Corea link i also listened to him + seen him lift 600 lb at 60 YO at the phila convention center fitness fair! sad that he was too stubborn to seek modern medicine in his emergency situation! there is prolly some genetics involved BUT only the individual KNOWS what they eat, drink + do on a daily basis!! regardless of our situation i believe that we can help ourselves with proper healthy choices!!
