Excess consumption of potassium(K).

[Kiat]

Is excess consumption of potassium can cause heart problem? I means that the potassium act in our body to slow down and stop the heart beat(just like cause our heart to become hard and unable to pump easily). Is this true?
If it is true, how about excessive of sodium inside our body since sodium and potassium are in the same group in periodic table(has same chemical properties)?
Is drinking too much of water everyday can cause low blood pressure and drinking to little of water everyday can cause high blood pressure?
Is drink tea able to 'wash' out the fat and cholesterol inside our body just after we consume fatty or high cholesterol food?
Any recommended nutrition to have a better health(I means a perfect one)?

I, too, research medicine just out of plain curiosity. Some people do it because they seek a degree, some want to be the healthiest (nothing wrong with that), some want to live to be 110. As long as what I learn keeps me away from terrible pain I'll be happy.

I am not a medical doctor or professional, so this is not to be taken as medical advise whatsoever.

I have read that high potassium diets are not advised for those with renal failure/kidney disease. I'm sure there are plenty of red flags in these areas for those with Heart and Liver Disease as well depending on the type of condition, etc.  

Beyond that, we know what the RDA limits are for these electrolytes. You're guess would be as good as mine on this one.  

"If it is true, how about excessive of sodium inside our body since sodium and potassium are in the same group in periodic table(has same chemical properties)?"

I know that there is a relationship between Magnesium and Potassium. I assume there's something there's a connection between sodium and potassium, but I wouldn't begin to know what the specifics are.

I do know that the sodium level usually drops a little bit in diabetics with higher glucose levels, whereas it rises when the blood sugar level gets down there too low. There's something there between potassium and copper, too, but I forget what that relationship is now.

"Is drinking too much of water everyday can cause low blood pressure and drinking to little of water everyday can cause high blood pressure?"

This might be true to some degree, but I'm sure there's a little more to it in most cases when you take the electrolytes into consideration unless somebody is drinking massive amounts of water or something like that?

"Is drink tea able to 'wash' out the fat and cholesterol inside our body just after we consume fatty or high cholesterol food?"

Never heard of that one. That Green Tea's sure popular these days, though, isn't it.

Stress/worry is probably still the biggest concern that's out there. Beyond that, everything that our doc's and nutritionalist's tell us, I'm sure-2 drinks a day or less, more exercise, 6-8 glasses of water a day, quit smoking, quit using drugs, no sex unless you're married, 6-8 fruits and veges per day, low fat meats to include 2 servings of fish each week, and avoid trans/partially hydrogenated "Anything" and refined/processed flours/treats as much as possible.  

I myself have included plastic gloves and a face mask when I go out into public, along w/ a daily dose of 500mg C everday, and I'm as every bit as powerful as a mule~.

Just kidding, w/ the exception of the Vitamin C.

Just on a personal note, the best thing I ever did was to quit worrying about my health. Proper diet and lifestyle are very important, w/o question, but at this point I am reasonably convinced that stress itself is probably the top enemy to health.

I spent two years researching medicine. Along the way, I was convinced that I had about 50 different medical conditions along the way. Turned into a full fledged Hypochondriac in the process.

I can still remember the day that I presented my longstanding doctor, who is a dear friend, with a Thiamine/Molybdenum/Manganese/Sulfur chart that I had constructed on a small piece of cardboard paper.

I can only imagine what some of today's doctors think about this wonderful thing we call the internet. The poor things have probably been driven to the loony bin themselves with all of the "Experts" like me sauntering in and out of doctor's offices in today's computer world.

One day I just stopped worrying about all of it. That was the greatest thing I ever did for my health. My sanity came back, and I immediately felt better.

There are certainly very real, serious medical conditions that exist, we know that. Medical health is not to be taken lightly by any stretch of the imagination.

But on the same hand, I do think that sometimes we can make ourselves sick-physically, I mean that. The lay out of the Endocrine system proves that it's possible, I think.

Even in those cases of actual medical illness, one can't help but wonder sometimes what type of role stress itself has in the process that eventually facilitates for the eventual existance of disease. Deep down many of us probably know that answer, to some extent, anyway.

Good luck to you, ma'am.
