Where can I find a dietitian who is smart about mineral supplements?
What is your opinion of colloidal minerals? Thanks for your help!
Colloidal minerals are molecules of minerals suspended in a liquid. The particles are not dissolved and may carry an electrical charge which enables them to combine with another particle to make a compound and precipitate out as a solid. These electrically charged particles are not the same thing as ions or cations which are electrically charged atoms or molecules.
Most colloidal minerals are clay dissolved in water. Depending on the source of clay, it may contain toxic minerals like aluminum or lead.
I have searched medical research and found nothing that suggests colloidal minerals are more or less absorbable than mineral supplements in pills. In fact I have not seen any research on absorption of colloidal minerals after checking what is available in a Medline search and many nutrition reference texts. To that conclusion, I deemed the information about colloidal minerals to be from testimonials which is passed on as selling propaganda.
I am an exercise physiologist and weight management consultant. I enjoy your web site and your comments, but I wanted to get your take on why the industry standard for dietitians is to not recommend vitamin/mineral supplements except for those who are not getting "The RDA".
I don't really know how you feel, but I fundamentally disagree with this principle. For an exercise physiologist, I have a pretty good nutrition knowledge base, which has shown me that I do not know anyone, not one person who eats the Recommended Dietary Allowances "by the book". In a perfect world, we wouldn't need supplements except in disease and/or preventive states (calcium for osteoporosis, selenium for heart ailments, etc.). I agree that much of the current supplement forms are not very absorbable (except colloidal 98% absorbable), but it would probably be advisable to have all of us taking vitamins and minerals because you and I both know that we will not get the public eating correctly. No way! It just seems logical to recommend people to take vitamin and mineral supplements (which cost about as much as eating out once a month). Sorry to sound cynical, but the "expensive urine" line (which I have used myself) just doesn't seem to have much merit anymore. Just my opinion though. Thanks for your time!
What research have you read that substantiates that colloidal minerals are 98% absorbed? I have searched the medical literature as well as searching over 75 nutrition journals and did not find one article on colloidal minerals. To that conclusion, I deemed the information about colloidal minerals to be from testimonials which is passed on as propaganda.
For your information, a lack of selenium can cause disease of the heart muscle, but does not account for all cases of Keshan disease. A toxic virus that attacks the heart muscle may also cause it and a deficiency of selenium may increase a person's susceptibility to the virus.
As to getting the public to eat correctly, people are intelligent and genuinely want to eat healthy as evidenced by the decrease in fat from 42% in the 1980's to around 35% today which has caused a corresponding decrease in heart disease in America. I believe in providing the public with information that can improve their health and quality of life as long as it is substantiated by nutrition research. The public needs this information to make healthy food choices.
