Exercise 4.Change the sentences as in the model (using Passive Voice instead of Active Voice) :
Model: Enzymes need copper for metabolizing. – Copper is needed by enzymes for metabolizing.
1)Iron delivers oxygen to the body’s cells.
2)Vitamins and minerals strengthen each other.
3)The skin creates vitamin D when it is exposed to sunlight.
4)The body absorbs iron through the help of vitamin C.
5)Polish scientist Casimir Funk made up a combination word "vitamine" from vital and amine.
6)Medical men used lipid from fish oil to cure rickets during the late 18th and early 19th centuries.
7)In 1881, Russian surgeon Nikolai Lunin studied the effects of scurvy.
8)Japanese scientist Umetaro Suzuki isolated the first vitamin complex in 1910.
Exercise 5. Read the text:
Along with vitamins human body needs a certain amount of minerals, which also have a broad range of functions. There are 20 minerals, which play significant roles in the body. They include copper, iodine, chromium, iron, tin, zinc, magnesium, sodium, potassium, chlorine, phosphorus, calcium, sulfur and others. Zinc is responsible for helping metabolize proteins and keeping enzymes functioning. Copper is needed by enzymes for metabolizing. Iodine assists the thyroid gland in working properly. Calcium and phosphorus build bones and teeth. Iron delivers oxygen to the body’s cells. Potassium helps muscle contraction, maintains the fluid balance of cells, helps transmit messages through the body’s nerves, and keeps the kidneys and heart working correctly.
Vitamins and minerals not only help the body function, but they work to strengthen each other. The body absorbs iron through the help of vitamin C. Vitamin D helps the body absorb phosphorus and calcium. Vitamins D and K are the only vitamins the body can supply for itself. The skin creates vitamin D when it is exposed to sunlight. Vitamin K is produced by intestinal bacteria. Outside sources must supply the body with all other vitamins.
Ideally, all of us would get all of the nutrients we need for optimal health from fresh, healthful foods. In reality, however, this is often difficult, if not impossible. So, our diet does not always contain all essential vitamins and minerals, which is why we have to take synthetic vitamins and nutritional supplements for optimal health.
Vitamin supplements are usually available as isolated vitamins or in combination with other nutrients. They are available in tablet, capsule, gel-capsule, powder, sublingual, lozenge, and liquid forms. Some vitamins can also be administered by injection.
Synthetic vitamins are vitamins produced in laboratories from isolated chemicals that mirror their counterparts found in nature.
It is good to know that all vitamin supplements work best when taken in combination with foodand unless specified otherwise, fat-soluble vitamins should be taken before meals, and water-soluble ones should be taken after meals. What is most important, vitamins should not be used as substitutions for a healthy diet, but rather as supplementation.
