Calories , alkaline foods- what matters

4 07 2012

We are what we eat. This much I agree.

But what do we actually get from eating? This is a big question. Nowadays, every box of food packages tells you how much calories contains. It makes people feels they know everything about it. The truth is far from that simple . The actual calories you get with this box depends on your body system. Provided that you have good digestive and absorptive guts, that is the maximum amount of calories you are going to get. There are individuals who eat lots of food but gains little weight.

As for the implication of eating acidity and alkalinity of food, the science is not murky. Most of thees claims on the Web is not supported by biochemistry and is not reliable. However there is one thing certain, each time we exhale, we eliminate carbon dioxide, a weak acid. Theoretically, we make our body more alkaline. Therefore, breathing deep is scientifically the best way of getting body more”alkaline”.

But wait, there is kidney. Kidney is the other body organ that regulate acidity of blood. Because of it,  the blood pH is always kept at 7.4 which is very important.  The acidity of urine output varies all over the place because kidney excretes more acid urine if the blood becomes acidified. It will excrete alkaline urine if blood is too alkaline.

A side note, a new study just released found that people who are on H inhibitor type of medicine, i.e. omeprazole based drugs for acid reflex problems, having significantly higher kidney failure or kidney cancer. The mechanism of the relationship  is complex but it is apparent that kidney has to work harder in these patients.

Joy of teaching

4 07 2012

Teaching is an interesting undertaking. Especially when the student group click.  It seems each class has its own character. Sometimes it is very enjoyable. Sometimes, it is kind of stuffy. Since I don’t think my teaching style varies much from class to class. I can only attribute such variation to the Qi of students.Some good Qi and some tough Qi.

These pictures were from one of the school clinic shift that I taught. We have a lots fun during this shift. It was the first time these students attended clinic rotation. It was interesting that in the 15 weeks period, three students suffered sport related injuries, which gave me opportunity to show them how to treat these conditions. Such situations were the best opportunity to learn.

These pictures were taken by one of the student , Ms. Georgia Good. Thanks, Georgia, for making me looks younger. -2009

Note: All of these students graduated in May of 2012. I attended the commencement. Georgia is bilingual and will be practicing in south  side of San Diago. Lori will be practicing in Escondido.

Good work and Good luck for all of you.- updated on July 4 th 2012

Too much of good thing?- drinking water

4 07 2012

According to UPI news , a young woman in California died shortly after entering drinking contest.

It is a tragic event that should not have happened.

Water drinking has become a fad in health industry. It is being promoted as a necessary step in maintaining a good health. Water bottling industry has prospered so fast in the last few years. Is there any medical study done to support it? I don’t think so, because it is bound to fail.

As we drink in water, immediately, our blood volume increase. The concentration of all components in the blood is diluted. Notes that we have about 4-5 liters of blood in the entire body. If we drink one liter of water, our blood will be diluted 1/4 to 1/5 in less than half an hour. The concentration of every components of blood, like electrolytes, blood cells all would be diluted. We will be very sick if we don’t get rid of it within this period of time.

This is what happened to this poor woman.

(Update: This was first written in 2007. There was a new study about drinking lots of water in reputable medical journal recently, 2011 which totally debunked the myth of benefit of drinking too much water.  Jan 2012)

Cold food and your health

4 07 2012

In the Far East, children are raised to avoid eating or drinking cold stuff. As kids grow up and spend more and more time watching television﹐t hey are exposed to a different value system in which “cool” is good, and icy cold is exciting. They begin to question the validity of the tradition.  After all, ice cream tastes so good and  icy drink tastes so satisfying. What can possibly be wrong?

Many things happen when our body is exposed to cold: blood flow slows down, muscles contract. Therefore, if we ingest a large amount of cold food, our intestine motility slows which increases the absorption of foods. This tends to increase body weight. What is more problematic is the coldness descends down to the lower place which is the low abdominal area and causing dysfunctions of ovaries and uterus of females. Increasing more chance for dysfunction of reproductive organs. One such disorder is the painful menstruation. I often have to advice female patient who suffers from dysmenorrhea to put heating pad during menses and in between.

We are not saying cold stuff can not be used at all. Knowing the consequences, for most people, moderation is the rule of the thumb. Many people have problems with pimples, especially young people. It is too hot inside, spicy food would not be appropriate. Too cold food is not appropriate either. It is a delicate balance act.
