Keep On Top Of Your Bodies pH : Get The Acid / Alkaline Balance Right

Several factors affect the pH or acidity/alkalinity of our blood, with some of the most prominent factors including exercise and the food we eat. From the outset, it’s important to note that the actual pH of a foodstuff itself is not necessarily the same as the effect the food has on your body’s pH. A great example of this is citrus fruit because despite them being relatively acidic prior to consumption; they’re actually alkaline-forming once they are assimilated into the body. So why worry yourself about the effects certain foods have on your body’s pH? Well research by Schwalfenberg (2011) refers us back to the eating habits of the Paleolithic era, and it’s pretty clear that the foods we eat on a daily basis have taken a change for the worse in many ways. You’re probably aware that it’s not ideal to consume too much fast food, processed meals, sugar and saturated fat, and yet as a nation we continue to binge! More specifically, since the agricultural revolution (some 10,000 years ago) and industrialisation (in the last 200 years), we have seen a rise in salt relative to potassium, and thus a rise in chloride compared to bicarbonate. The modern diet is generally low in potassium and fibre, whilst being significantly higher in saturated fat and simple sugars. As you will come to see later in this article, some foods have a more acidic forming tendency than others which may alter the pH of your blood, potentially placing strain on your organs, most notably your kidneys. If your diet is high in processed sugars, fat, sodium and chloride, and is low in fibre, potassium and magnesium, then your body is likely to remain acidic (pH below approx 7.35). If an acidic internal environment persists, or if the kidney is unable to remove enough acid from the body then a condition known as diet-induced metabolic acidosis may arise. Although an extreme case, metabolic acidosis may cause headaches, anxiety due to hypoxia (low internal oxygen supply), nausea, vomiting, muscle weakness and weight loss. Metabolic acidosis is extreme, but a real possibility if a poor diet and lifestyle persists (Schwalfenberg, 2011).

By no means is this article intent on scare mongering, nor is it prescriptive in any way, but if you feel that you are consuming a large amount of acid forming foods (according to the list below) then it may be in your interest to amend it slightly in order to get the balance right. Following the nutritional guidance on the Eatwell plate is the safest bet every time, it illustrates the appropriate foodstuffs in their optimal proportions for health and longevity, but for your information why not take a look at the list below for the relative pH of some common foodstuffs, and try to get a balance between the acid and alkaline forming foods.

Try some of these Alkalising supplements

Try an alkalising agent such as PhD Nutrition Greens pH 7 or Udo’s Choice Beyond Greens which helps to buffer hydrogen ions and thus reduce the acidity of your blood…a key contributing factor to cramp!
