I didn't really want to get in on this discussion... I agree we as a society are not eating as healthy as we should, but I'm also concerned about people believing the Ludite hype that everything man-made is somehow tainted, usually because some of the "studies" don't have a good basis in science (afterall, they tend to view the scientific method as being man-made and therefore evil).
Yes I have heard of this as well. Our diet is killing us. I believe most of the health problems we have in the US is caused by poor diet (too much salt and sugar) and lack of exercise.
Just found this list of alkaline foods.

But I just wanted to look at this list of "alkalline" foods, see if basically they were saying to stay away from pop (which has a lot of acid in addition to sugars) and opt for buffering type of foods that would balance out the acids. At first the article sounded reasonable mentioning an acid / alkaline balance (and my eye caught the 80 / 20 balance mentioned), until I read "Your health depends on the balance of an alkaline environment, created by eating foods such as
tomatoes...."
Tomatoes?! You've got to be kidding me! Tomatoes are one of the fruits that is very high in Vitamin C (aka Ascorbic
Acid). I then went down to the chart and saw some more surprises: Lemons, Grapefruit, Limes! WTF?! Any citrus fruits have a load of Ascorbic Acid as well as Citric Acid (hence "
Citrus" fruits): "Citric acid exists in greater than trace amounts in a variety of fruits and vegetables, most notably citrus fruits. Lemons and limes have particularly high concentrations of the acid" from Wikipedia. If you were to test any of these fruits, you'd find them all to be acidic, not basic. Heck, many cleaning products use orange or lemons because of its acidic qualities.
After that I knew their science is "misleading" at best (and more likely just a bunch of
). They also mentioned salt as being acidic, except basic chemistry will tell you that it has a neutral pH (add equal amounts of Hydrochloric Acid and Sodium Hydroxide and you get a neutral solution of salt water: HCl + NaOH -> NaCl + H
2O). In fact, other salts may even have an alkaline pH: Sodium Bicarbonate (or baking soda, an ingredient used in baked goods, which is a no-no according to that chart) has a pH closer to 10!
And then their issue with sugar is also wrong. In order for something to be termed acidic or basic, the levels of hydrogen ions in water need to change. However, dissolving sugars in water does not dissociate any hydrogen ions from the sugar molecule, so the pH level remains neutral. And this is true for sucrose (table sugar) as well as lactose (the sugars in milk) and fructose (the sugars found in fruits). Some bacteria may convert sugars into acidic products (hence the fermentation process of fruits and grains as well as the sour taste in spoiled milk), but sugars in and of themselves are not acidic.
Now I do agree that we should be eating more fruits, vegetables, whole grains, and lean proteins and less processed foods (like white breads and pastas), salts, and sugars; but that does not have to do with their acidity. And Omega fatty acids are healthier than other fatty acids, so olives, flax, sunflower seeds, and fatty fish (like salmon) (and all of their associated oils) are better sources of fats than red meats; however fatty acids, no matter what form, are still acids. So in general, I'd agree with their food chart (although dairy products are also a good source of lean protein (esp. skim milks), and calcium, so I also wouldn't avoid mothers' natural food), but I'm just not buying that it has anything to due with pH levels.
