The principles behind the alkaline diet is that our blood and body tissues have a mainly neutral to slightly alkaline PH. Our bodies have biological methods to regulate PH, but when our diets consist of mainly acid forming foods, we start to suffer thom becoming too acid. Our blood never becomes acid, but the body may use alkaline sources within to maintain a blood PH. Alkaline Diet proponents suggest that alkaline chemicals in our bones may be used, leading to osteoporosis and brittle bones.
It's not the PH of the food that matters, it's the PH effect of the food on our bodies once consumed that's important. Doctor Thomas Remer divised a formula for this called PRAL. (PRAL stands for Potential Renal Acid Load)
Further down the page you'll find resources to help you which foods to increase and which to decrease in order to make your diet more alkaline. As a general guide, meat and processed foods tend to become for acidic once consumed (even if they are alkaline before eating), whilst vegetables and fruits tend to become more alkaline. Some foods such as lemons are quite acidic before you eat them, but they become very alkaline once processed by the body. You may find this video helpful to understand more.
This Acid Alkaline Diet page gives a good overview of the problem of Acidosis, and the food that contributes to it.
These don't come with detailed instructions so when they arrive here's what to do:-
1. Remove a strip from the box, and reseal the box.
2. Have a wee, and whilst you do so, hold the strip so that you wee on the coloured squares for a couple of seconds. (For most accurate results do this mid flow)
3. After 20 seconds compare the colours on the two squares with those printed on the box.
4. Your result is the closest match.
Test first thing in the morning to start with. By regularly testing after you have eaten or drunk certain foods, you'll start to understand the impact of food on your urine PH.
If you are eating a typical diet, you'll probably be acidic, but once you've spend a week or so eating more alkaline and less acid foods and drinks you'll see the change.
