Question

Liver

Most people these days know how important a healthy liver is for general health. The liver works around the clock to protect us by eliminating any toxic substances from our body. When individuals are exposed to too many toxins, for example by living in an environment that poses health risks, or consuming a high rate of unhealthy foods, the liver can become overworked and will not be able to deal with the toxins effectively. At that point, we become vulnerable to diseases.

Recent studies have observed an alarming increase in liver-related problems for the general population. However, to date, there has been no convenient and tasty food to support a healthy liver. Lemons are great, but few people enjoy consuming lemons.

Fortunately, liveRplus Industries appears to have succeeded in creating a delicious new health drink, Liv-Pro, which is intended to supply the body with the nutrients needed to boost liver health and encourage the elimination of toxins.

Larry Fretnot, executive director of liveRplus Industries, funded a series of studies to investigate the effectiveness of Liv-Pro. One-hundred-twenty participants were recruited for this study. All participants were workers at liveRplus Industries and had easy access to the beverage in the cafeteria and from vending machines throughout the factory grounds at a discounted rate.

The scientists conducting the study distributed a questionnaire to the volunteers which assessed the amount of Liv-Pro consumed daily for two weeks. Based on these data, average consumption per person was calculated.

To test for liver health, researchers look into the eyes of a person. This is because the clarity of the iris, the colored band around the eye’s pupil, is an indicator of liver health. Thus, to measure liver health, iridology was used, in which a judgment is made on the color of the eye’s iris and this is indicated on a clarity scale.

The results of the iridology tests in the current study showed a correlation between the variables of interest: liver health increased with higher consumption of Liv-Pro.

"We are encouraged by these first results," Mr. Fretnot announced Friday. "Variations in liver health was a result of LivPro consumption! We believe our beverage will lead to healthy livers across the world, but first we are currently planning a study with the general population to follow up on this study."
