Selenium reduces the risk of bladder cancer

Tuesday, March 9th, 2010

selenium foodsSelenium, a trace mineral found in grains, nuts and meats can help prevent high risk of bladder cancer, according to a U.S. study

Researchers at Dartmouth Medical School compared the selenium levels in 767 newly diagnosed cases of bladder cancer at levels of 1108 people without the disease.

While no association between selenium and bladder cancer in the overall study population, the highest rates of selenium are associated with reductions in bladder cancer among women, moderate smokers and patients with p53 positive cancer bladder.

The results were published in Research for Cancer Prevention.

“There are different ways in which developing bladder cancer and is considered a major route involves alterations in the p53 gene, cancers of the bladder resulting from these changes are associated with more advanced disease,” the study for Margaret Karagas professor of community and family medicine at Dartmouth’s Norris Cotton Cancer Center, said in an American Association for Cancer Research.

Detox Diets

Monday, March 1st, 2010

Detox DietsThe British Dietetic Association, representing 6,000 dietitians in the UK, says there is no “potion or lotion that would” magically “to rid the body of chemicals.

The theory behind detox established as dangerous toxins that accumulate in the body, was dismissed by the health experts said the body is constantly cleaning.

Thousands of people are expected to try a detox diet in the coming weeks, spurred by guilt to drink more and eat during the festive period.

A wide range of different equipment, including vitamin preparations and beverages with diet plans are available on the street and in health shops.

Detoxification plans are based on the theory that chemicals and other pollutants that remain in our bodies over time, cause health problems and should be removed.

Subjected to a detox diet is usually recommended to cut a wide range of food “unhealthy” and supplement their diet with vitamin and drink. (more…)

Pasteurization

Saturday, February 27th, 2010

Pasteurization, the process of juice for long then. In general, there are two processes 1. Transient heating (HTST) 2. Additional heating under high temperature (UHT) Both methods thus destroy a large portion of the vitamins and minerals. The juices are heated between 70 ° to 138 ° for an average of 10 to 20 seconds with the natural fermentation bacteria are slain.
As a result, the natural nutrients are also destroyed. VFS provides non-pasteurized fresh chilled juices with the necessary anti-oxidants, vitamin C and other natural substances as it should be! ! ! ! !

Concentrates on what is the truth?
A concentrated juice is obtained by removing the natural water first and then return to add. The concentration process takes place under vacuum at temperatures below pasteurization.

VFS has also proved that it is impossible to see the differences / NFC Trials and quality concentrates. VFS works with this quality concentrates because we sincerely believe that this is the best option, and not just for the taste and nutritional values, but also for the environment because of the lesser volume of shipping. We sacrifice no quality to obtain a homogeneous product.

Fructose Effect in the Diet

Friday, February 26th, 2010

Fructose, a natural sugar found in fruit, could be responsible for obesity, British scientists propose in the magazine New Scientist. Their research shows that fructose more adverse effects than other sugars. Fructose is present in fruits, fruit juices and jam and is often used to sweeten soft drinks and fast food to make. Under study is the number of calories less important than the type of food that contains sugar.

The researchers gave 33 overweight people with test meals consisting of 14 days long 30 percent fat, 55 percent complex carbohydrates (like bread and rice) and 15 percent protein. In the ten weeks after they received a diet in which one quarter of the energy came from fructose or glucose. Both groups were in that period about 1.5 kilos.

Who got fructose, was much more developed abdominal fat and cholesterol than the glucose group. Abdominal fat is a dangerous kind, because it surrounds your vital organs. Moreover, it increases the risk of diabetes and cardiovascular disease.

Fruit Diet

Thursday, February 25th, 2010

What? This drink was inspired by Sangria. Sangria is a Spanish-based drink red wine with fruit pieces.

Preparation
Cut one orange into small pieces.
Cut an apple into small cubes.
Add any other pieces of fruit such as strawberries or melon or berries again.
Put the glasses around one third fruit.
Pour a dash of agave syrup (or honey or rice syrup or wheat syrup or grenadine syrup or juice) at.
Mix the fruit with the syrup.
Fill the glass with red grape juice and serve cold with possibly a fast ice.

Tip:
You may also be replaced by grape juice or other juices such as a combination of fruit juices.
A pinch of cinnamon adds flavor (sometimes also added to Sangria).

Influence Heat on the Juice

Wednesday, February 24th, 2010

The influence of thermal treatments in the quality of orange juice

The main objectives of the thermal treatments are:

  • Inactivation of the Pectilmetilesterasa. This is achieved by subjecting the juice to a temperature of 98 º C for 30 seconds.
  • Prevent the presence of Hidroximetilfurfural. This requires a short period of thermal treatment to be used.
  • The fundamental limitation we face is that a long treatment time increases the amount of HMF and the quality of the resulting product is reduced.

The Chemical Structure in Fruit Juice

Tuesday, February 23rd, 2010

One of the main aspects related to the treatment of the pulp is the mass transfer. HRS Spira Tube has a piston pump particularly suitable for this purpose, a pump that is hygienic and can develop pressures of 40 bar. One of the fundamental aspects of the process is the thermal treatment is performed using a three-tube heat exchanger (HRS Spira Tube model). This product flows through a heat exchanger annulus formed by concentric tubes, allo wing the tree units especially useful.

Liquids of high viscosity, Non-Newtonian fluids, Liquids that contain small particles Closing of the process makes use of an aseptic filler of the type “Bag-in-Drum” or “Bag-in-Box”, both designed by HRS Spira Tube, which the product is packaged in aseptic containers. Preformed and pre-sterilized packages of between 5 and 1000 liter are commonly used.

Eliminate the Bitter Taste of Fruit

Monday, February 22nd, 2010

Once the orange juice is obtained, we need to remove the bitterness from the juice. This is done through a process designed to limo nina, narangina y hesperidina eliminate from the juice. Specifically for Limo Nina the initial concentration could rise to 20 ppm and the final result must be less than 0.1 ppm. The process begins with stabilized fresh juice and reconstituted juice 15 Brix. They are centrifuged to separate the pulp from the juice. Lewait Bayer resin is added to the juice and is then spread to a storage tank where the thermal treatment is performed.

Several Steps to Extract Fruit Juice

Saturday, February 20th, 2010

  • First, the oil is removed. This process is performed without damage to the fruit. It is done to avoid unwanted flavors and the highest level of aldehydes obtained.
  • Second, the juice is extracted. The technology used to cut and squeeze the orange and very different from the In-line systems. The HRS process does not damage the skin and thus prevents contamination of the juice.
  • Third: the juice is separated from the peel and seeds. With this process we reduce the bitter flavor, getting a low reading speed fiber and a low viscosity in the NFC.

The resulting juice has a minimal content of the bitter flavor, a pleasant color, minimum natural oil content and an increase in the number of intact cells juice. Limo Nina The content is also reduced.

The average cell size in the pulp is increased by a higher percentage of floating pulp. We must also stress that the process does not use water in the extraction process, the optimized power consumption and contaminants in the wastewater are minimized.

The role of vitamins in the diet

Thursday, February 4th, 2010

vitamin in dietVitamins are complex organic substances required in the diet in small amounts in comparison with other components such as proteins, carbohydrates or fats. The lack of vitamins in the diet result in various deficiency diseases. Vitamins do not provide energy or matter but involved in their use in the synthesis and maintenance of tissues and in countless metabolic processes. They are indispensable in the daily diet for healthy people.

They are divided into two (2) groups:

Water-soluble vitamins
* Not stored in large quantities
* Requires regularly in the diet
* Generally not toxic excess

Fat-soluble vitamins
* They are stored in the liver
* Not easily absorbed or excreted
* The excess can be toxic
