Rhubarb and oxalic acid: is there cause for concern?

From April until the end of June, supermarkets everywhere will be stocking rhubarb in their produce section. Due to its sweet yet sour taste, it is ideal for compotes, jams and cakes. However, rhubarb also contains an extremely high amount of oxalic acid, a compound that is unhealthy in high amounts and which can cause kidney stones. In this article we look at just how high the oxalate content of rhubarb is and how it can be reduced through proper preparation.



How much added sugar is in my food?

Sugar is added to many foods and beverages during the manufacturing process to improve taste, texture or shelf life. This can be in the form of various types of sugar, including sucrose (table sugar), fruit sugar (fructose), glucose-fructose syrup or high-fructose corn syrup. Because sugar is so cheap, it is found in many foods where you would not expect it, such as bread or sausage. So we are constantly – consciously or unconsciously – consuming added or other easily digestible free sugars and this is not without consequences.


Does oxalic acid in plant milk increase the risk of kidney stones?

As recently as a few years ago, plant-based milk alternatives were considered an exotic, niche product. Today, however, they enjoy incredible popularity and are available in a multitude of varieties. These include milk from:

  • legumes: soy, pea, lupine
  • nuts: almond, hazelnut, cashew, macadamia
  • and other sources: coconut, hemp, quinoa

Probiotics and food intolerances: some interesting facts

Our intestinal tract contains around 39 trillion microorganisms that help us break down indigestible food components – fiber, for example – for the body to make use of them. Most of the intestinal flora is found in the large intestine. Over time, the metabolic processes of many lactic acid bacteria and bifidobacteria have become closely interlinked with our own, resulting in a symbiosis that benefits both the bacteria and the host. The bacteria get nutrients and a fertile place to multiply and in return form vitamins and short-chain fatty acids that are essential for many bodily functions.

“Eat some glucose with a serving of fruit and your body will better absorb the fructose contained in the food.” Such a statement can be found on many a nutrition website, along with the claim that just one glucose tablet can remedy any digestive ailment.

How can vegetarians improve their omega-3 fatty acid status?

The omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) almost exclusively occur in fish. This raises the question: How can vegetarians meet their needs for these essential fats?

Uric acid and its salts, known as urates, are an end-product of the metabolism that is excreted with the urine. Unfortunately, urates are poorly soluble in water. In contrast to other mammals, humans don't have enzymes to convert them into more soluble compounds. Therefore, the human uric acid level is very high in comparison – it is just below the physical solubility limit.
