Books like this will use all this pseudoscientific language to make it seem like what theyre saying is legit. This seems legit right? Has so much science words there. Well guess what? Its straight up bullshit. You cannot acidify the body. Our blood is a buffered system, pH roughly 7.3. If it varies much from that you will have a much biger problem – youll be dead.
CHEM 181 Winter 2019 Malka A-r 289 What does it mean that it’s a buffered system? It means that our body can automatically neutralize excess alkali or acid. So what do they mean by a diet that features alkaline foods? Well they mean that these foods, if combusted in the laboratory, leave behind an alkaline residue. But this has nothing to do with alkalizing the blood. These foods can change the pH of the urine, which is the only body fluid that can be affected in any significant way by the diet. They try to take some smidgen of scientific fact to try to justify their argument. They’ll talk about Otto Warburg, who back in the 1920s, got a Nobel Prize for studying the multiplication of cancer cells in the laboratory an noted that they multiplied more quickly in an acid environment. But that had nothing to do at all with eating any kind of food. Many of these companies that promote this notion of eating alkaline foods will also want to sell you various kinds of devices like this pH water device, whereby it makes alkaline water. They charge like 2 000$ for this crap. The promoters make a lot of money, but sometimes the get caught :0 Robert O Young, one of the biggest promoters of the alkaline diet has recently been arrested. He was charged with 18 counts of felony, including practicing medicine without a license and grand theft. He’s out o n 100 000$ bail The purpose of this course is to separate the sense from the nonsense. Our profs want to leave us with some important points: 1. The presence of a chemical does not equal the presence of a risk : it’s a question of which chemical, what it is doing, how much of it is in there 2. There are no safe substances, just safe ways to use substances: the dose always matters 3. High dose in animal studies may not reflect human exposure and risk. Animals may react very differently from humans and even from each other. ▪ Example: Dioxin is known as the most toxic chemical known to man. Its lethal to Guinea Pigs but does nothing to hamsters 4. Effects depend on molecular structure, not on whether a compound is synthetic or natural. Ancestry does not matter! What matters is what it is, how much we know about it. Even natural can be harmful 5. There are opposing views on almost everything: However, it is rare that these opposing views are equal. There will always be more experts on one side than on the other side. Usually one is much more scientifically based on the other. 6. We can never eliminate all risk. Science can never prove that there is no risk associated with a chemical. Eliminating one risk may introduce another 7. Anecdotes are not data: Anecdotes are all over the place, but you can’t take it as fact. 8. Repeating a false notion does not make it true
