What are Protein Shakes?


Why are protein supplements required?

Proteins are very important components, which are required by the body for building muscles. It is also required for the growth and development of the body. An average individual requires nearly one gram of protein per pound of the individual's body weight. However sometimes it simply becomes difficult to regularly take such a quantity. It is then protein supplements like protein shakes are the most convenient method to compensate for the regular intake.
When should protein shakes be taken?

It is better to take proteins from regular foods but sometimes it is better to take protein shakes than taking proteins from regular food. The ideal time for taking protein shakes is in the morning. Breakfast is the most important meal of the day and therefore protein shake is advisable for people who do not have the time to take a good and healthy breakfast. Moreover, in the morning the body does not get any nutrients for eight or nine hours and it is best to consume a protein shake during this time, as it is easy to digest and at the same time it gives the body the required nutrition. It is also good to take a protein shake after a rigorous workout. After a good workout the muscles wear and tear and this time it is good to supply protein to the body. Protein shakes are the best way to build muscles and reduce body fat. It is advised to take two or three protein shakes in one day.

Good protein shakes and how to make protein shakes tastier

Protein shakes are also very useful for vegetarians or non-meat eaters. It is also good for people who are not capable for digesting rich protein content foods. Good quality protein powder or shakes are prepared from whey or eggs. It is best to avoid soya protein, as soya is readily available in the market. Protein shakes can be made tastier by adding ice or different flavours of smoothies. Milk can also be added to the powder instead of water. In this way it increases growth rate as protein supplied to the body also increases. However sometimes it can be harmful as well as they can result in stomachaches.

Protein shakes are supplements and therefore they should be the last way to fulfill the body requirements of protein. Nothing can supplement the protein that comes from the animal and plant material.

Better Proven Radiosurgery Over Craniotomy

Although there are a few different ways of delivering radiation to destroy tumors or slow their growth, they have found a great deal of success and preference among neurosurgeons, oncologists and doctors with subspecialties in brain tumor growths.

Radiosurgery is considered a relatively "recent" technique for treating brain tumors. Its main advantage is that it is non-invasive, which means that the flesh and skull do not need to be cut, sawed or bled in any way. This will be a brief discussion on how radiosurgery gives doctors and clinicians advantages over invasive brain surgery applications and some information about how it's applied.

When a patient undergoes radiosurgery for a tumor they generally use one of two techniques to expose the growth to radiation. The two main methods of application are either through a linear accelerator or a stereotactic frame. The applications of each are through such trade names as the Lineac (linear accelerator) or the Gamma Knife (stereotactic frame). Each uses subatomic particles that can be focused on the tumor while passing through the flesh invisibly, which gives the patient and hospital advantages such as:

- Reducing the cost of staff and tools that are needed for normal surgery techniques
- Less time in the hospital (often the patient can leave the same day)
- Smaller bill to the patient and insurance company
- Better avoidance of healthy tissue damage to healthy parts of the brain

Gamma Knife: The Gamma Ray Helmet Technique

The Gamma Knife is not actually a knife at all, as explained earlier. This is a technique that uses gamma rays to bombard with the intent to disable the growth of a tumor. Its biggest advantage is that it normally only needs to be administered once, no going back into the brain, no extensive time is needed like a scalpel and saw procedure.

The Gamma Knife is a form of radiosurgery that uses a helmet type of radiation applicator. Radioactive isotopes of cobalt within the helmet emit gamma rays. They can be fashioned onto the head of the patient and aimed at the tumor with superb accuracy. The gamma wave forms are positioned so that they pass through all the healthy tissue harmless as can be and converge upon the tumor in an attempt to disable the tumor's ability to subdivide and perpetuate its destructive behavior of branching out.

The Gamma ray is one of many particles used in radiotherapy; protons, neutrons and x-rays are also used in various techniques.
