[What is Phytosterol?]

Phytosterols are compounds found in plants that resemble cholesterol. The National Institutes of Heath report that there are over 200 different phytosterols, and the highest concentrations of phytosterols are found naturally in vegetable oils, beans and nuts. Their benefits are so recognized that foods are being fortified with phytosterols. At the supermarket, you may see orange juice or margarine advertising phytosterol contents. After reviewing the health benefits, you may want to add phytosterol-rich foods to your diet.

[Benefits]

Cholesterol-Lowering Benefits

The most well-known, and scientifically proven, benefit of phytosterols is their ability to help lower cholesterol. A phytosterol is a plant compound that is similar to cholesterol. A study in the 2002 issue of “Annual Review of Nutrition” explains that phytosterols actually compete for absorption with cholesterol in the digestive tract. While they prevent the absorption of regular dietary cholesterol, they themselves are not easily absorbed, which leads to a total lower cholesterol level. The cholesterol-lowering benefit does not end with a good number on your blood work report. Having lower cholesterol leads to other benefits, such as a reduced risk for heart disease, stroke and heart attacks.

Cancer Protection Benefits

Phytosterols have also been found to help protect against the development of cancer. The July 2009 issue of the” European Journal of Clinical Nutrition” offers encouraging news in the fight against cancer. Researchers at the University of Manitoba in Canada report that there is evidence that phytosterols help prevent ovarian, breast, stomach and lung cancer. Phytosterols do this by preventing the production of cancer cells, stopping the growth and spread of cells that are already in existence and actually encouraging the death of cancer cells. Their high anti-oxidant levels are believed to be one way phytosterols help fight cancer. An anti-oxidant is a compound that fights free radical damage, which is negative effects on the body produced by cells that are unhealthy.

Skin Protection Benefits

A lesser known benefit of phytosterols involves skin care. One of the contributing factors in the aging of the skin is the breakdown and loss of collagen — the main component in connective skin tissue — and sun exposure is a major contributor to the problem. As the body ages, it is not able to produce collagen as it once did. The German medical journal “Der Hautarzt” reports a study in which various topical preparations were tested on skin for 10 days. The topical treatment that showed anti-aging benefits to the skin was the one that contained phytosterols and other natural fats. It is reported that phytosterols not only stopped the slow-down of collagen production that can be caused by the sun, it actually encouraged new collagen production.

Hi guys, today I prepared a video about a very simple extraction that is to say starch from cooking potatoes and its relative test with commercial tincture of iodine. Before starting just two words about starch. it is a natural polymer present in rice, ceral, potatoes and it is a source of energy for living creatures.
It is composed of two different polymers: amylose 20% and amilopecten 80 %. Both of them are chains composed of unities of alpha glucose. Here we can see a simplified picture of starch molecule which is much more complex.
Now let’s get started. The procedure is so simple that also a child could do that without problems. Simply take a one hundred grams potato and peel it. Now simple grate it. Once it’s done put it to a beaker with two hundred millimitres of hot water. Now mix for about one-two minutes. Then filtrate with a cook filter to another container. With the lasting part that is to say the grated potato you can repeat the operation several times adding water and mixing, and filtrating again but this is optional. After 5-10 minutes starch, insoluble into water will precipitate out. Here we can see the white precipitate, pure starch. Simply moving the liquid phase to another beaker you will isolate the product. Let it dry at room temperature. Here we can see starch and it appears white, a little bit creamy but after essiccation it will be cristalline.
Now, to test it is really starch and not magic powder, we will use some tincture of iodine ( a mix of ethanol, water, potassium iodide and elemental iodine). To test it put some starch into a test tube with some water and shake. After add the tincture of iodine that you can diluite with water or not. However, the solution will become dark blue coloured. What happens is that iodine ions (I3- ) combine to amilose and they make the compound take up this colour.
My greetings, see you on the next experiment.
