  • The Saccharine Disease

    Conditions Caused by the Taking of Refined Carbohydrates, Such as Sugar and White Flour
    • 1 Edición
    • T. L. Cleave
    • Inglés
    The Saccharine Disease, Conditions Caused by the Taking of Refined Carbohydrates, such as Sugar and White Flour contends that the causation of these conditions has been obscured through confusing distinctions between unnatural, refined carbohydrates and that of natural, unrefined carbohydrates like fruits and whole meal flour. The author notes that all the foregoing conditions are really the manifestations of a single master-disease—that many of the major diseases of modern societies are caused by consuming unreasonable amounts of refined carbohydrate foods. The author discusses that in the short time that man has changed his diet, evolutionary adaptation is left behind. He gives two rules to prevent and arrest all saccharine disease manifestations: Do not eat any food unless you definitely want it, and avoid eating white flour or white sugar. These two rules will prevent gastric or duodenal ulcer, diabetes, coronary disease, constipation, complications of varicose veins, hemorrhoids, E. coli infections, obesity, and some skin conditions, As a retired Surgeon-General of the Royal Navy, the author bases his assumptions on evolutionary, epidemiological, and other scientific or historical work. This book can give insights to dieticians, food researchers, nutritionists, people on diet, and general medicine practioners.

    Food Legislative System of the UK discusses the principles underlying the country's food laws, the historical context of today's food legislation, and the process for amendments in legislation. The book also reviews the influences on the system such as those arising from interest groups, the changing diet, and health environment. In addressing the Food Legislative System of the United Kingdom, the book tackles various examples of food legislation and numerous food- related advisory bodies. Industry, consumer, or enforcement pressures can initiate changes and modifications of laws. Once ministers are convinced that a prima-facie case exists for amending food legislation, they will seek advice from various authorities; make a draft, and present it for full parliamentary procedure. For example, the "Food and Environment Bill" has passed through Parliament by ministers representing the Ministry of Agriculture, Fisheries and Food, while the "Food Bill" has gone through another route with the chief legal officers and company. The book emphasizes the mechanisms through which change is achieved, as well as the points when opportunities exist for interest groups to make their views known to the decision makers. The book can be helpful for food lobbyists, consumer food groups, nutritionists, political scientists, and heads of food and welfare organizations.

    Idiotypy in Biology and Medicine aims to serve the increasing interest and involvement in the practical aspects of idiotypy in biological systems. The concept of idiotypy has received wide recognition and interest far beyond the area of immunology. Experiments and interpretation of findings, reported here, clearly support the general nature of the idiotype concept in manipulating biological systems to correct pathological conditions or to improve the immune adaptation to environmental factors. The book is organized into three sections. Section 1 discusses original concepts of idiotypic manipulations. It reviews old and recent data important for the concept of an idiotype network and reports on attempts to deal with the T-cell receptor paradox; explains the immune system in terms of a circular idiotype network that can be demonstrated by sequential immunization; and emphasizes the need for restrictions in network interactions. Section 2 addresses the role and activity of idiotypic and antiidiotypic antibodies in the regulation of the immune system. Section 3 takes the issue of idiotype-antiidiotyp... out of the realm of the immune system and discusses it as a new principle to analyze and manipulate biological systems in general.
