"This is a very impressive book. A very well supported hypothesis is presented. It is well researched and the diet is practical and clearly works for many children."

This independent review of The Hidden Drug: Dietary Phosphate of the UK journal Enzyme Digest was published in the Spring 2002 (No. 56) edition.

"Most of us have heard of the environmental problems caused by phosphate run-off from cleaning products and agri-chemicals into waterways and seas, but know little about the health dangers from consuming the processed, phosphate-ridden foods and drinks that are common in the modern consumer society. If you're concerned about children's health in the consumer society, this is a must-read."
This Book Review appeared in the Australian NEXUS Magazine, August-September 2002.

Dr Neil Beck M.D., author of Beating Heroin and Head of The Chemical Health Centre - treatment for heroin and other addictions - in Perth, Western Australia stresses that diet is significant in treating ADD/ADHD, heroin addiction and other chronic conditions. Read his recommendations here, his view on the underlying cause of heroin addiction and find a link to his website on how to beat heroin and get your life back.

I highly highly recommend this book to anyone with an interest in understanding and overcoming ADD/ADHD:

There is evidence that phosphate in the diet is above the optimal level and has been increasing in the last 20-30 years, as it has become more widely used in many types of processed foods. In particular, the ratio of calcium to phosphorus in the diet has declined. Independent evidence from diverse sources indicates that excess phosphate is an unappreciated cause of illness and can be treated.

While phosphorus is an essential nutrient, excess phosphorus acts like a kind of intestinal sludge, keeping both calcium and magnesium from being well absorbed. One of the most alarming dietary changes in this country (USA) during the past decade has been the increasing consumption of soft drinks by teenagers. We take in more phosphorus than we can use.

The Hidden Drug - Dietary Phosphate written by Hertha Hafer and skilfully translated from the German by Jane Donlin, is a 'must read' for all parents of ADD/ADHD children who are willing to try a novel but simple non-drug approach to the problem.

For two decades it has been known, but not widely publicised, that a number of environmental factors including exposure to certain chemicals has been associated with this disorder. The author, Hertha Hafer, has an impeccable science background and is herself a concerned parent of an ADD child. Based on trial and error, scientific method and a deep love for her son, she has unravelled a perplexing mystery and formulated a fascinating new concept in managing these children. She has put her knowledge to the test with her own son with stunning results.

Perhaps this book will not help every child with ADD/ADHD, but it nevertheless is essential reading for parents to assist them in making an informed choice about their child's treatment.

Our point of view:

There are two main reasons as to why this book may not help every child with ADD/ADHD.

One: phosphate sensitivity is not the problem. The simple pH Test is scientific proof for Hertha Hafer's theory and will soon determine whether phosphate is the problem or whether the problem lies elsewhere. Heavy metal toxicity or other nutritional deficiencies may play a role in causing additional mineral imbalances. If this is the case, we recommend that you seek the advice of a health professional.

Two: Sadly not every parent has the determination to follow the low-phosphate dietary instructions, even though natural therapies are potentially less harmful and much more beneficial in other ways. As Professor Swank, MD says, "A lifestyle change will have to take place, which may be a challenge for you, but the challenges of living with a disability are much greater."
