  • 8. What foods are good sources of protein?  Tofu, Meat, chicken, fish, eggs, beans and nuts.  Food that supplies all 9 essential amino acids is called a complete protein. Ex. Most animal sources are complete, while plant sources are often incomplete.  People who don’t eat animal protein can combine sources of plant proteins to be sure they get the essential amino acids.  Ex. Beans and rice form a complete protein when eaten together.

What if you have too little or too many vitamins? •Vitamin deficiencies can cause a wide range of health problems several diseases rarely seen in the U.S. These include: including • scurvy (caused by not enough vitamin C) Scurvy leads to the formation of spots on the skin, spongy gums, and bleeding from the mucous membranes. The spots are most abundant on the thighs and legs, and a person with the ailment looks pale, feels depressed, and is partially immobilized. In advanced scurvy there are open, suppurating wounds and loss of teeth. • beriberi (caused by lack of vitamin B) – A nervous system ailment. Symptoms of beriberi include severe lethargy and fatigue, together with complications affecting the cardiovascular, nervous, muscular, and gastrointestinal systems. • rickets (caused by a lack of vitamin D) a softening of bones in children potentially leading to fractures and deformity. Vitamin deficiency in this country primarily cause:  Poor regulation of internal body processes.  The body not being able to produce high levels of energy.

Water allows the body to: Use water-soluble vitamins Carry oxygen in the blood.  Regulate body temperature  When water deficiency is severe, the body systems shut down and death occurs. Some experts believe that large amounts of water may dilute and wash water-soluble vitamins from the body.
