QUESTION 1
The Extracellular concentration of potassium (K) is between 3.5-5.0 mmol/l. 98% of the total potassium in the body is in the Intracellular fluid (approx 3700mmol for a 70kg man) while only 2% is in ECF (approx 65mmol). The typical daily intake of potassium is 50-150mmol which exceeds total amount of potassium in extracellular compartment.
The distribution of potassium between Intracellular and Extracellular compartment is determined by the balance between inward and outward movement of potassium. Uptake of potassium into the cell is dependent of Na+,k+-ATPase, where as efflux from cell is passive.
As earlier stated potassium intake in meal in a day is more than the total potassium content of the ECF compartment, the amount of K+ in a single meal could cause lethal hyperkalemia.
Two mechanism are used to keep K+ within normal range in the body
CELLULAR BALANCE
RENAL REGULATION
CELLULAR BALANCE
Kidney response is the most effective regulator of K+, but the mechanism is very slow. In the interim cellular buffering acts to keep the K+ level within range. As ECF K+ rises, its uptake into the cell increases and when ECF K+ falls it shift out of the cell. it uses passive for outward movement and active for inward movement. The Na+,k+-ATPase which actively transport k+ into cell is stimulated by an elevation in k+ and inhibited by a decrease in ECF k+ concentration.
Other factors that can affect k+ shift in and out of the cell are
• ACIDEMIA: increase H+ concentration in acidosis increases potassium concentration in the extracellular fluid. This occurs as a result of exchange of extracellular hydrogen ion for intracellular potassium.
• INSULIN: Insulin promote uptake of potassium by skeletal muscle and liver cells. i...

...piration, and it helps to exhale CO2 and raise the PH back to normal.
EFFECT OF INCREASE IN RESPIRATION RATE
Regardless of the cause of decrease arterial PH, respiratory system attempt to compensate and raise the PH by eliminating CO2 from the body thus respiration rate and depth is increased to get rid of CO2 and bring the PH back to normal.

Calcium and Potassium modifications are specialized individual according to a specific disease, age and inadequate amounts of calcium or potassium higher or lower than normal value. Calcium modifications are the results of to low or to high calcium levels. When calcium levels are to low compromises in bone integrity will occur. Adults 50 years of age and older are encouraged to increase calcium intake to help prevent osteoporosis. Patients with thyroid dysfunctions may experience low hormone levels
consuming high-quality protein and usually limits fluids. Some patients may also need to limit potassium and even calcium” (Nephcure). Throughout the course of this paper various aspects are addressed. these include: the role of the kidneys, the importance of professional guidance, the reasons why people follow a renal diet, monitoring sodium intake, monitoring potassium intake, monitoring phosphorus intake, protein consumption, and fluid control. The Role of the
Potassium is freely filtered in the glomerulus. Two thirds of the potassium is reabsorbed along the proximal tubule. The potassium concentration in the proximal tubule is roughly equal to that of plasma. In the descending limb of Henle a small amount of potassium is secreted into the luminal fluid and is reabsorbed by the ascending limb of Henle. The concentration of potassium is the distal convoluted tubule is now lower than the concentration in the plasma. The connecting tubule and cortical connecting

Essential minerals are divided into: • Major or macro minerals • Trace or micro minerals 1) Macro minerals are present at large levels in the animal body or required in large amounts in the diet. Macro minerals include: • Calcium • Magnesium • Potassium • Sodium 2) Micro minerals are often referred to as trace minerals, meaning they are present at low levels
Based on the Dietary Reference Intakes (DRIs), I calculated DV’s daily nutrient consumption and it was adequate for her age and gender. Dietary Reference Intakes (DRI) is a new tactic in evaluating and measuring food consumption for healthy people. The DRIs are a more established set of standards and embrace more parameters, for choosing healthy food, such as Tolerable Upper Intake Levels (UL), Recommended Dietary Allowances (RDA), Adequate Intakes (AI) and Estimated Average Requirements (EAR) (USDA
extremely healthy. Nevertheless, I knew that I lacked physical activity. To begin the project, I used the estimated energy requirement prediction equation (EER) and the physical activity values to calculate the estimated amount of calories that I need to intake on a daily basis. I found out that I should consume about 1900 calories per day according to my age, gender, weight, height, and physical activity. Simultaneously, I used the body mass index (BMI) equation and found out that my BMI is 19.49, meaning

What is Potassium? Potassium (K+) is an important mineral the body needs to maintain and regulate many functions in the body. It is essential to life because it helps balance body water, regulate blood pressure, maintain heart function, and facilitate various cellular and tissue functions. Its function inside the cells is influenced by it positive electrical charge, which makes it a cation and an electrolyte, or a substance that regulates the flow of molecules, particularly water, across cell membranes
arteriolar vasodilation13. Dietary Approaches to Stop Hypertension (DASH diet) have recommended increasing dietary potassium intake through consumption of fruits and vegetables which are high in potssium14. There several other proposed beneficial effects of K+ such as decreased sensitivity to norepinephrine and angiotensin II, and baroreceptor sensitivity15. The positive effects of dietary potassium on lowering blood pressure are well documented but whether these benefits extend to nocturnal blood pressure
which is under the required intake. Protein’s is 46g, my average consumption is 45g which is one gram lower from my target. Carbohydrates on the other hand shows satisfactory with target of 130g which is 45-65% in Calories percentage, my average consumption is 173g, which is 50% Calories. My Total Fats target 20 – 35% of total Calories, my average consumption is 41% which is over the required consumption. Lower calories will give me less energy but if I lower my fats intake, I will hopefully lose weight
are loaded with healthy Total Fat, Potassium, Carbohydrates and Fiber. In a (173 g) avocado there are 27 g of total fat. 877 mg of Potassium, 15 g of Carbohydrates, 7 g of Protein and 12 g of Fiber. Nuts (I eat almonds and raw peanut butter, but most of the nuts are similar in nutrition facts). Raw nuts are always a preferred choice, if you are going to have salted nuts, then you better keep track of your sodium intake. Nuts are also high in Total Fat, Potassium, fiber and is a good source of protein
inorganic substances are necessary for “cell metabolism, nerve impulse transmission and growth and development” (Byrd-Bredbenner, Moe and Beshgetoor 485). Minerals can be categorized into major or trace minerals. The major minerals include Sodium, Potassium, Chloride, Calcium, Phosphorus, Magnesium, and Sulfur. Trace minerals are Iron, Zinc, Copper, Manganese, Iodine, Selenium, Chromium, Fluoride, Molybdenum and Ultratrace minerals. Analyzing my 3-day food record reveals an interesting perspective into
recall on 09/27/15, 09/28/15 and 09/29/15. I selected these three dates to conduct my food intakes because School and work schedules tend to cause me to make unhealthy food choices due to my schedule. The results from my three day food recall displayed that my calories intake was 1,681.69 while the recommended is 2,089.42, which means I consumed 80 percent of the recommended amount. For saturated fat my intake was 19.39g vs. the recommended 20.89g, showing that I was in range for the recommendations
Protein- There is no set upper limit for protein. One’s protein intake should not exceed more than 35 percent of total food enegery and no less than 10 percent (Whitney, Folfes 182). One of the side effects of protein deficiency is the slowing of the body’s processes to slow down. Protein defficiency can also stop some bodily processes. Protein deficiency can cause slowed growth, impaired brain and kidney functions, poor immune systems, and inadequate nutritent absorption (Whitney, Rolfes 182)
