Why are we getting Chronic Diseases and the need of better nutrition

Since World War II over 60,000 new chemicals have been created and introduced by us into our planet. They are found in our soil, water, air and even in our food. It is almost impossible to predict what they will do. What is possible to measure is the increasing rate of Chronic Degenerative Diseases across the globe. These include diabetes, heart disease, neurological, arthritis, macular (eye) and many other forms of degeneration. 

Even countries like India now have more Chronic Degenerative Diseases than we do infectious diseases.
So in today's environment we have more pollution, more chemicals, more stress and less physical exercise and in all kinds of combinations these add up to the Chronic Diseases we now have a tsunami of.
Our body is designed by God to heal itself. Almost all our systems can heal themselves. But our repair system is in overload with all the attacks  on it by these environmental factors; so it is even more important for us, now more than ever, to give our body the right micro-nutrients for it to heal itself and reverse this epidemic of Chronic Diseases.
