Part I:
TASK: Select a vitamin or mineral and address the associated question(s). AVOID DUPLICATES–scan your peers’ posts before making your selection. To that end, be sure to label your subject heading with the selected vitamin/mineral.
Imagine you are attending your yearly health risk assessment. When you came to the appointment, you thought you had a proper diet and were of average health. It turns out, the doctor that examines you has a special interest in nutrition. She notices some inconsistencies with what you discuss with her and suggests that you may have a deficiency or toxicity of your selected vitamin or mineral. Your post should include the following information:
Based upon the vitamin or mineral that you have chosen, what were your doctor’s observations and diagnosis?
Do you have a toxicity or deficiency? Explain any disorders associated with the deficiency or toxicity.
Briefly describe what your recommended daily allowance based upon your profile (sex, age, physical status, etc.) should be, your present intake estimate, and your action plan (adjustment in diet, etc.).
If left untreated, what might be some of the more serious long term and detrimental effects this might have on your body?
Which special populations (pregnant women, children, etc.) are most affected and why?
What other prevention, treatment, and safety measures might be beneficial to regulate your health

Upon visiting your doctor they noticed that you had an increase in blood pressure since your last visit. You explained to your doctor you changed some of your eating habits to help eat healthier. Your doctor asked what were some of the items you cut out to “eat better”. You explained that you ate a baked potato every night with dinner but recently read they were bad so you cut it out and exchanged it for broccoli. You had never been one for vegetables but figured that was a good change, and had to be healthier. Little did you know because of a limited diet you cut out your main source of potassium.
Your doctor explained that because of your dietary change that you were beginning to show signs of a potassium deficiency. While not directly proven there was significant evidence that correlated a lack of potassium in the diet with higher blood pressure. Americans are not consuming enough potassium in their diet but you reduced it enough that it was potentially causing issues with your health (Callahan, Leonard, and Powell, 2020). As a male of your age, your adequate intake of potassium should be around 4,700mg (2015-2020 dietary guidelines. (n.d.)). There is no upper limit so a high dietary intake would not affect you as excess is expelled in your urine. Your doctor would like to see you begin to add some high potassium foods (e.g. baked potato with skin, white beans, sweet potatoes with skin, and salmon) to help correct this deficiency. If you continue to maintain a deficiency your blood pressure could get worse, begin to form kidney stones, have issues with your bone mineral density, and potential to develop type 2 diabetes (Callahan, Leonard, and Powell, 2020) .
Your doctor explained that most Americans have this issue and that it is easy to fix by eating a propper diet and most supplements do not contain enough potassium to fix this issue (Callahan, Leonard, and Powell, 2020) . Additionally, your doctors wishes you to consult a dietitian prior to making any large changes to your diet may have unknown consequences.

Calcium
Based upon the vitamin or mineral that you have chosen, what were your doctor’s observations and diagnosis?
Vitamin D and Calcium are crucial for bone health in the body, while Vitamin D can be levels can be determined through blood tests, there are no tests to determine whether a patient has a Calcium deficiency.
Do you have a toxicity or deficiency? Explain any disorders associated with the deficiency or toxicity.
Figuring I have a Calcium deficiency, the results of having this are long term and severely affect one’s health. Hypocalcemia is the condition of a deficiency of calcium.
Briefly describe what your recommended daily allowance based upon your profile (sex, age, physical status, etc.) should be, your present intake estimate, and your action plan (adjustment in diet, etc.).
For a fit 24-year-old male, such as myself, the recommended daily allowance of Calcium is 1,000 mg. I currently am only consuming around 700 mg a day lading to my body turning to my bones to take Calcium in order to keep the levels in my body normal. In order to increase my level of incoming calcium, my doctor recommends eating more dairy products such as yogurt and milk or taking supplements daily.
If left untreated, what might be some of the more serious long term and detrimental effects this might have on your body?
If hypocalcemia is left untreated it can result in rickets and osteoporosis later in life as the calcium is sapped from your bones in order keep bodily function normal.
Which special populations (pregnant women, children, etc.) are most affected and why?
People with Vitamin D or Magnesium deficiencies are also at risk of contracting hypocalcemia. Newborns are at risk as well as their bodies are not fully developed.
What other prevention, treatment, and safety measures might be beneficial to regulate your health?
Really just careful watch of my Calcium intake will help curb and potential developments of hypocalcemia.

Vitamin D
1. Based upon the vitamin or mineral that you have chosen, what were your doctor’s observations and diagnosis?
-Weak bone structure and high blood pressure.
2. Do you have a toxicity or deficiency? Explain any disorders associated with the deficiency or toxicity.
-“Hypervitaminosis D” is a very rare side effect that comes from vitamin d. This is caused by vitamin d supplements, rather than natural sources itself. This is because the body regulates the intake of vitamin d by nature. When hypervitaminosis d is active, you are prone to vomiting, urination, and nausea.
3. Briefly describe what your recommended daily allowance based upon your profile (sex, age, physical status, etc.) should be, your present intake estimate, and your action plan (adjustment in diet, etc.).
-RDA for a 21 year old male is 5 micro-grams of vitamin d. In order to combat the deficiency, I must lower my vitamin d intake. I can trust my own body to regulate the intake of vitamin d naturally, but it will not be able to reject any extra vitamin d I put into it via supplements.
4. If left untreated, what might be some of the more serious long term and detrimental effects this might have on your body?
-This could potentially lead to a weakening of the bones and muscle. The excess calcium could also lead to the formation of calcium stones within the kidneys. It is also likely to result in pain coming from these areas.
5. Which special populations (pregnant women, children, etc.) are most affected and why?
-Everyone is affected by this the same. It could be argued that younger people are more prone to these side effects. This is because more vitamin d is required for older individuals.
6. What other prevention, treatment, and safety measures might be beneficial to regulate your health?
-It may be beneficial to lose the vitamin d supplements. It depends on the situation, because if you are outside all day long then you are likely getting the correct amount of vitamin d. It may also be beneficial to cut down on fish, red meat, and egg yolk servings as these are alternative sources of vitamin d.
