This chapter discusses minerals and their importance for the human body. It covers both major and trace minerals, including their roles and dietary sources. Major minerals discussed include calcium, phosphorus, magnesium, sodium, potassium, chloride, and fluoride. Trace minerals discussed include chromium, manganese, sulfur, iodine, selenium, iron, zinc, and copper. The chapter explains how these minerals help maintain fluid balance, bone health, muscle function, and other essential processes in the body. Risk factors for osteoporosis are also covered.
The "Nutrition Basics: Macronutrients" lesson will introduce and explain the three most calorie-dense foods-- fats, proteins, and carbohydrates. You will get an understanding of what most foods are made of and why they are important.

Physiological and nutritional significance of minerals paper 3.pptxSanatsawant
1.Introduction :
“Minerals in food are the elements present in food that are required by our body to develop and function properly.”
2.Nutritionally important minerals are
a. Sodium: A) Nutritional Significance :-
Sodium is taken in diet along with chloride in the form of common salt.
Sodium is found in table salt, baking soda, monosodium glutamate, egg, meat, fish, dairy products, poultry, olives & pickled food.
The Recommended dietary allowance of sodium is in
Child :- 0.3 - 2.5 mg/day
Adult :- 1.3 - 5.0 mg/day
B) Physiological significance :-
Body needs small amount of sodium to help maintain normal B.P. & normal function of muscles and nerves.
Sodium is important in maintaining fluid balance as the concentration of sodium is directly related to the osmotic pressure of plasma .
b.Potassium:A) Nutritional Significance :-
K + is a major intracellular cation.
Normal concentration of K + in plasma is 3.5 – 5.0 Meq. per litre.
Main sources of potassium are banana, orange, potatoes, sweet potatoes, watermelon ,mushrooms, dried plums etc.
B) Physiological Significance :-
It influences muscular activity.
It is involved in regulation of acid-base balance.
It plays an important role in cardiac function.
c.Chloride: A) Nutritional Significance :-
Cl- is taken in the diet along with Na+ in the form of common salt.
Plasma volume of Cl- depends upon Na+ & HCO3- levels in plasma.
Low Na+ level is associated with low Cl- .
High Na+ level is associated with high Cl- .
High HCO3- is associated with low Cl- .
Low HCO3- is associated with high Cl- .
The sources of chloride are table salt, tomatoes, Olives , meats etc.
The recommended daily allowance of chloride is
In children = 1500 - 2300 mg /day
In Adults = 1800 - 2300 mg/day
B) Physiological Significance :-
It is important for the production of HCI in the gastric juice .
It is an essential part of digestive (stomach) juices .
Chloride is needed to keep the proper balance of body fluids .
d.Phosphorus:Nutritional Significance : -
Phosphorous is an important mineral for teeths and bones .
It is most widely distributed in foods such as milk, cheese, egg, nuts, meat etc.
About 85% of phosphorous in the body is stored in bones and teeths .
Recommended daily allowance of Phosphorous is,
In Childrens :- 1200 mg/day ( because bone formation and development is more rapid at this stage of life)
In Adults :- 700 mg/day
B) Physiological significance : -
It is used for the maintenance of bones and teeth.
It is used to produce DNA & RNA.
Phosphorous is required by the body for Creating, utilizing and storing energy.
e.Nutritional Significance :-
Calcium is an important mineral for bones & teeth .
It is widely distributed in foods such as milk, cheese, egg, beans, cabbage, etc.
Of the total Ca absorbed in the body 45 % bound to protein 45 % exists as diffusible Ca2+ & 10 % is complexed with anions.
Absorption of Ca depends upon Ca:P ratio & also vitamin D that promotes absorption of Ca from food .
