  1. VITAMINS Name the two (2) classes of vitamins. Fat soluble contains vitamins A,D,E and K. Water soluble contains vitamin C and all the B’s. Name three (3) things about fat soluble vitamins: The body absorbs and transports to the bloodstream. They are trapped in the cells & remain there. They can be toxic if consumed in excess. Vitamin A Needed for: the health of the skin and eyes. Lack of it causes: dry rough skin and eyes have a hard time adjusting to dim light (night blindness) Excess amounts cause: liver damage Is found in: fish oils, egg yolks, liver, butter, and cheese.

  2. VITAMIN D Needed for: growing strong bones and teeth Special attention for: pregnant women Lack of it causes: Rickets, a condition in which bones are poorly formed. Is found in: butter, egg yolks, liver, & fish oils Also found in: ultraviolet rays (sunshine) Has been added to: Milk (fortified)

  3. VITAMIN E Prevents vitamin A from being destroyed too quickly and it also strengthens the cell membranes of red blood cells (RBC’s). It is found in salad oils, margarine, whole grain cereals, and green leafy vegetables. Excess is stored under the skin and in the ovaries and testes. Excess amounts interfere with the work of the glands and tissues.

  4. VITAMIN K does what? • Helps the liver to produce a protein that is needed for blood clotting. • Sources include: Cauliflower, spinach, cabbage and eggs. • Vitamin K can also be produced where? Large intestine • Water soluble vitamins. Name 4 things about them: • Absorbed by the body directly into the bloodstream. • Once there, they travel freely. • Circulate in the water –filled compartments of the body. • The kidneys can detect and remove excess water –soluble vitamins.

  5. Vitamin B1 Also known as thiamin, is needed for nerves,muscles, and the digestive system. Without vitamin B1, what can happen? Nerve and muscle disorders can develop. What disease can develop and what does it affect? Beriberi, and it affects the heart and nervous system. Good sources of Vit. B1 or thiamin includes: pork, whole grain cereals, lean meats and nuts.

  6. Vitamin B2 Also known as riboflavin and niacin (B3) are found in liver, cheese, green leafy vegetables, beans, milk, eggs and fish. Both B2 and B3 are good for the skin and digestive & nervoussystems. A lack of niacin causes dry red patches to form on the skin. This disease is called Pellagra. Vitamin B12 Vitamin B12 (cobalamin) prevents severe anemia called Pernicious Anemia . Vitamin B12 does what? Helps to increase the number of RBC's. It is found where? Liver, leafy vegetables, milk, eggs, and cheese.

  7. VITAMIN C Also known as ascorbic acid. It is found in citrus fruits such as oranges, lemons, limes and grapefruits. Other sources include: tomatoes, potatoes & cabbage. A person who needs more Vitamin C may exhibit the following signs: fatigue, bruises easily, and bleeding gums. A severe lack of Vitamin C may cause a condition called scurvy. it is characterized by weakness, pain in legs and joints, and bleeding gums.

  8. WATER • Water (H2 0) is found in every cell in the body and next to air is the most important element needed for life. 65% of the body is made up of water and we should take in 8 to 10 glasses of water daily. • You do not get energy directly from this nutrient. Nevertheless, water is essential for all life processes. • Nearly all of the body’s chemical reactions, including those that produce energy and build new tissues take place in a water solution. • Water is the primary component of blood & tissue fluids. Water carries dissolved waste products out of the body and helps digest food. • Water helps to regulate body temperature. • Heavy perspiring or severe diarrhea can result in dehydration which causes serious reduction in the body’s water content.
