- High-protein foods are particularly rich in phosphorus, so milk and milk products, meat, fish, and eggs are the primary sources of phosphorus in the average diet.
What are some signs of iron deficiency?
- (1) Inadequate dietary iron
- (2) Excessive blood loss
- (3) Inability to form hemoglobin because of a lack of factors such as Vitamin B12
- (4) Lack of gastric hydrochloric acid, which liberates iron for intestinal absorption
- (5) Inhibitors of iron absorption
- (6) Intestinal mucosal lesions affecting the absorptive surface area
Iodine is essential to health because it affects what?
Iodine's basic function is as a component of thyroxine (T4), a hormone synthesized by the thyroid gland that helps control the basal metabolic rate (BMR).

Why is sodium restricted in cardiovascular conditions? (What does too much sodium cause?)
Excessive sodium intake has been linked to hypertension in individuals who are salt sensitive.
What can fluid collection within the interstitial spaces cause?

- Milk and milk products are the most important sources of readily available calcium.
- Milk products such as yogurt, cheese, and ice cream are excellent sources of dietary calcium.
- Source of Calcium for Vegetarians: Chinese cabbage, broccoli, collards, kale, and turnip greens
Iodine is necessary for the what? (Hint: hormones)
