Here high blood pressure means persons who have BP >140/90 that is also known as hypertension.Here high concentration of Na salts increasing the water retention by kidneys therefore reduces the water removal ability of kidneys it indirectly effects the blood pressure due to increased volume of blood.Here KCl is beneficial effect on blood pressure because it is antagonist(opposite effect) to Na and also lowers systolic blood pressure indirectly maintains heart beat in a healthy manner so Kcl diet has more beneficial effects rather than Nacl therefore it can used as substitute on doctors advise

Homework Problem 5 Salt-free diets are often prescribed to people with high blood pressure. Participants were randomly selected for the study and the following data were obtained as part of a study to measure the effect on diastolic blood pressure as a result of following a salt-free diet for two weeks. Assume the differences in diastolic readings are normally distributed in the population. Did completing the salt-free diet result in a significantly different diastolic blood pressure of participants? Use a...

Scenario 1: From the NY Times, April 27, 2015 A diet high in potassium appears to protect teenagers from high blood pressure in adulthood, while a low-salt diet has no effect, according to new research. A new study tracked the eating habits and blood pressure of 2,185 nine and ten year-old girls for almost 10 years. The study found that sodium intake had no long-term effect on the girls’ blood pressure. However, they did find that girls who ate diets...

6. Of all people in one population, 21% have high blood pressure and 36% are overweight. In addition, 42% of people who are overweight also have high blood pressure. Let H represent the event that a person has high blood pressure, and O represent the event that a person is overweight. In each part of this question, you must first express each probability in terms of the events Hand O and justify any computation through the use of a formula....

Several recent studies have suggested that people who suffer from abnormally high blood pressure can benefit from regular exercise. A medical researcher decides to test her belief that walking briskly for at least half an hour a day has the effect of lowering blood pressure. She conducts a small pilot study. If results from it are supportive, she will apply for funding for a larger study. She randomly samples three of her patients who have high blood pressure. She measures...

After exercise, some people will have hypotension (low blood pressure) and it could last for hours. This can cause dizziness, light headaches and possibly faint upon standing. It is believed that Endurance training could reduce the post-exercise hypotension. To prove this, a research studies 24 people, with similar physical condition, and 12 of them are randomly selected to go through the Endurance training, while the other 12 did not. Their systolic pressure (mmHg) after 30 minutes as below. Group Sample...

2. (5 points) In 1998 a headline in USA Today read, "Prayer can lower blood pressure." The story stated that attending religious services lowers blood pressure more than turning into religious TV or radio." This article was based on an observational study which followed 2391 people aged 65 or over for 6 years. They found that people who attend a religious service once a week and prayed or studied the Bible once a day were 40% less likely to have...
