Whey Protein Importance

Written by Hamoon Arbabi

Studies on whey demonstrate it's an even better protein supplement than previously thought. Although whey protein's health benefits have only recently been elucidated,repparttar use of whey protein for medicinal purposes has been prescribed sincerepparttar 148542 time of Hippocrates. In fact, there are two ancient proverbs fromrepparttar 148543 Italian city of Florence that say, "If you want to live a healthy and active life, drink whey," and, "If everyone were raised on whey, doctors would be bankrupt." In previous issues, we've chronicledrepparttar 148544 extensive research showingrepparttar 148545 many potential health benefits of whey protein concentrate. The majority of that research was done inrepparttar 148546 1980s and early 1990s, and was extremely persuasive. Scientists have continued their research on whey proteins with even more impressive results. What follows is some ofrepparttar 148547 more current, interesting and useful research on whey proteins. Whey and Cancer Additional studies have been done on animals regarding cancer-causing chemicals to see what effects whey protein concentrate would have on cancer prevention or treatment. Scientists fed rats various proteins and then subjected them torepparttar 148548 powerful carcinogen dimethylhydrazine. As withrepparttar 148549 previous research,repparttar 148550 rats fed whey protein concentrate showed fewer tumors and a reduced pooled area of tumors (tumor mass index). The researchers found whey protein offered "considerable protection torepparttar 148551 host" over that of other proteins, including soy. 1. Even more exciting, in vivo research on cancer and whey showed whey protein concentrate inhibitedrepparttar 148552 growth of breast cancer cells at low concentrations (Baruchel S. and Vaiu G., Anti Cancer Research, 1996). Finally, and most importantly, a fairly recent clinical study with cancer patients showed a regression in some patient's tumors when fed whey protein concentrate at 30 grams per day. 2. Whey and Glutathione This new research using whey protein concentrate led researchers to an amazing discovery regardingrepparttar 148553 relationship between cancerous cells, glutathione (GSH) and whey protein concentrate. It was found that whey protein concentrate selectively depletes cancer cells of their glutathione, thus making them more susceptible to cancer treatments such as radiation and chemotherapy. It has been found that cancer cells and normal cells will respond differently to nutrients and drugs that affect glutathione status. What is most interesting to note isrepparttar 148554 fact thatrepparttar 148555 concentration of glutathione in tumor cells is higher than that ofrepparttar 148556 normal cells that surround it. This difference in glutathione status between normal cells and cancer cells is believed to be an important factor in cancer cells' resistance to chemotherapy. Asrepparttar 148557 researchers put it, "Tumor cell GSH concentration may be amongrepparttar 148558 determinants ofrepparttar 148559 cytotoxicity [poisonous to cells] of many chemotherapeutic agents and of radiation, and an increase in GSH concentration appears to be at least one ofrepparttar 148560 mechanisms of acquired drug resistance to chemotherapy." They further state, "It is well-known that rapid GSH synthesis in tumor cells is associated with high rates of cellular proliferation. Depletion of tumor GSH in vivo decreasesrepparttar 148561 rate of cellular proliferation and inhibits cancer growth." The problem is, it's difficult to reduce glutathione sufficiently in tumor cells without placing healthy tissue at risk and puttingrepparttar 148562 cancer patient in a worse condition. What is needed is a compound that can selectively depleterepparttar 148563 cancer cells of their glutathione, while increasing, or at least maintaining,repparttar 148564 levels of glutathione in healthy cells. This is exactly what whey protein appears to do. In this new research it was found that cancer cells subjected to whey proteins were depleted of their glutathione, and their growth was inhibited, while normal cells had an increase in GSH and increased cellular growth. These effects were not seen with other proteins. Not surprisingly,repparttar 148565 researchers concluded, "Selective depletion of tumor GSH may in fact render cancer cells more vulnerable torepparttar 148566 action of chemotherapy and eventually protect normal tissue againstrepparttar 148567 deleterious effects of chemotherapy." The exact mechanism by which whey protein achieves this is not fully understood, but it appears that it interferes withrepparttar 148568 normal feedback mechanism and regulation of glutathione in cancer cells. It is known that glutathione production is negatively inhibited by its own synthesis. Being that baseline glutathione levels in cancer cells are higher than that of normal cells, it is probably easier to reachrepparttar 148569 level of negative-feedback inhibition inrepparttar 148570 cancer cells' glutathione levels than inrepparttar 148571 normal cells' glutathione levels. Whey and LDL Cholesterol The positive health benefits of whey protein concentrate does not end with its effects on immunity and cancer prevention and treatment. Whey protein concentrate also was found to be a potent inhibitor of oxidized low density lipoprotein cholesterol. Current research suggests thatrepparttar 148572 conversion of LDL to oxidized LDL isrepparttar 148573 trigger that leads to atherogenesis...repparttar 148574 formation ofrepparttar 148575 plaque and lesions associated with atherosclerosis.

It’s Not Just About Dieting…

Written by Jan Nicholas

You may not like what I’m about to say, but dieting alone will not help you to lose weight. You have to give your bodyrepparttar exercise it needs. As I mentioned earlier, a couple of centuries ago, people were involved in a lot of manual labor.

This gave their bodies allrepparttar 148479 exercise that was needed. But due torepparttar 148480 changed life styles, most of us do not have to engage in strenuous work. Most of us sit in front of computers all day long or engage in other sedentary works.

It is because of this that exercise becomes crucial for weight loss. Generally people do not gain weight till their early twenties. But once they crossrepparttar 148481 25 mark, then visible signs of weight gain can be seen everywhere and inrepparttar 148482 mid section in particular.

There is something very important that you have to understand if you are really consideringrepparttar 148483 possibility of losing weight. You will have to consciously give your bodyrepparttar 148484 required exercise that it needs forrepparttar 148485 weight loss to be really effective.

Watching your diet alone is not going to yield results unless it is coupled with proper exercise. You have to make a conscious effort for this. Andrepparttar 148486 solution for this is a work out routine.

When we think aboutrepparttar 148487 life inrepparttar 148488 country, there is always something rosy about it. What is it thatrepparttar 148489 people inrepparttar 148490 country have that we do not? When you ponder about it you find that those lucky souls eat good food, they work really hard, by work I mean real physical work and they have good night’s sleep. Of course they do not have allrepparttar 148491 amenities and facilities thatrepparttar 148492 city life has to offer.

Butrepparttar 148493 city life comes with a lot of strings attached. People inrepparttar 148494 cities are generally less healthy thanrepparttar 148495 people inrepparttar 148496 country. One ofrepparttar 148497 reasons is pollution of course butrepparttar 148498 other reason is because people inrepparttar 148499 city do not get enough exercise.

Now, when I talk about healthy bodies please make no mistake about what I am referring to. I am not talking aboutrepparttar 148500 Mr. Universe kind of body,repparttar 148501 bodies that we see on WWF.

I am talking about people who are fit. And fitness and exercise are just two sides ofrepparttar 148502 same coin. They both go hand in hand.

In order to stay fit you need exercise and in order to exercise you need to be fit. But just because you are not fit now, it does not mean that you shouldn’t exercise.

And just like that, just because you do not have any visible excess fat on your body right now, it does not mean that you need no exercise. Exercise isrepparttar 148503 best way to keep obesity, cardio vascular disorders, hypertension and all those lifestyle-related disorders under control.

First of all let us get one point straight, exercise does not necessarily mean pumping metal. If you do haverepparttar 148504 time to go to a gymnasium everyday, then that is well and good.

But I suppose most of us do not haverepparttar 148505 time for a regular work out in a gym. Sorepparttar 148506 other alternative is to do it at home of course.
