  1. So helpful on picnics and when you are on the road plastic cutlery is. On the other hand, it is quite harmful to our environment and health. Normally it is made of polystyrene which will not decompose in centuries. As all other plastic it can get into wild animals food chain and then finally into human's. But it makes you wonder if it is toxic to human health before you even start considering the environmental impact. Is it likely that polystyrene ends up in tap water? What are the deleterious effects of polystyrene to our health?
  2. I have found an alarming scientific article on aspartame It looks that it is a really dangerous substance, perhaps even more than thought by most. The article concluded that doses much smaller than recommended daily intake influence people's neurobehavioral health, i.e. participants who consumed aspartame were prone to depression and other mental ailments such as irritation.  I would like scientists to look for similar researches and comprehensively write on aspartame effects on our brain in layman terms
  3. Much like prescription medicines, dietary supplements come with the potential for unwanted side effects. There are currently no requirements for clinical studies to verify the safety or even potency of a dietary supplement, as they are technically not allowed to claim any health benefits. Supplements also do not require a doctor’s prescription, making the vast majority of supplement use self-prescribed. This often means that people begin taking supplements without informed medical guidance. Many supplements contain active ingredients that can have varied and serious effects within the body, some desired, some not. In some cases, taking too much of a supplement can have serious complications. For example, some supplements can have unwanted effects before, during, and after surgery.[1] Supplements can also interact with prescription medicines to reduce or increase their activity, or to produce other unwanted side effects. Between 2008 and 2010, the American Association of Poison Control Centers (AAPCC) received 145,775 calls related to the side effects of dietary supplements, and the FDA (from 2008 to 2011) received 6,307 similar reports.[2] However even these numbers are still likely to dramatically underestimate the true scope of the situation, as most people suffering from unexpected side effects, illnesses, or drug interactions do not call a poison control centre or report the adverse reaction to the manufacturer of the supplement.  Potential supplement side effects can include gastrointestinal symptoms,[3]  liver toxicity,[4] heart attacks,[3] and even cancer.[5] Although these side effects can be serious and even fatal, consumers in general do not appreciate the risks. The use of the term “natural” on the product label often fools many into believing that the product is safe and can do them no harm, and the important ‘small print’ is often ignored. In addition to this, supplement manufacturers are not legally bound to indicate potential side effects on the product label. Increasingly popular diet and ‘muscle-building’ supplements can be some of the most dangerous. These types of supplements often contain stimulants which suppress the appetite, but which can also raise the blood pressure to dangerously high levels and increase the risk of a heart attack or stroke.[6] Whilst supplements can be beneficial to many users, individuals can react differently. Side effects can be experienced when using too high a dose of a product, when taking the recommended dose, or even when taking a less than recommended dose. Some supplements are marketed as having “almost no side effects”, but when combined with other substances, or taken too frequently, can quickly become toxic.[7] Vitamin C, for example, is often taken frequently to ‘boost’ the immune system, but taken in large amounts can cause diarrhoea. Other, more serious side effects are also possible - for example, the risk of lung and stomach cancers is significantly increased in those who consume 20-30mg/day of B-carotene.[8] In those taking calcium supplements, one study demonstrated a doubling of hospital admissions for gastrointestinal problems, a 17% increase in kidney stones and a 20-40% increase in the risk of a heart attack.[9] Once a side effect is found to be the result of dietary supplement intake in an individual, simply stopping taking the supplement will often lead to resolution of the side effect.[10] However this is not always the case, and some supplements can have longer-lasting effects, especially those with the potential for serious and even fatal side effects, such as cancer or increased risk of a heart attack.  Given this potential for serious and even fatal side effects, sound advice would be to think twice before opting to take dietary supplements and at the very least consulting your doctor before taking them, particularly if you are taking prescription medication. If, when taking supplements, you begin to develop side effects or symptoms, you should stop taking the supplement and consult your doctor before it is too late.   [1] Wang, CZ, Moss, J, Yuan, CS.

  4. Do you like to do exercises in the outside as I do, for example jogging along the cannal on early mornings? I do, but is it indeed good to our health if we are exercising in a city? I am a keen runner and used to run in the big city where I lived and air was badly polluted from cars and plants. I had never noticed any harm to my health until two years ago I moved to a small town with clean air. After several weeks of morning sports there I noticed that I can run longer distances and breath easier, also my skin began to look nicer. I think it is a result of breathing a cleaner air whilst living in a suburb.  It would be highly interesting to know if there are any research studies proving my experience and might even say it is better to stay put rather than downbeat your health by exercising on the dirty air city streets. I would like this article to tell if the city outdoors sports may still be more beneficial on the balance than staying put.
