Abstract

Antioxidants have become very popular in the news lately for their potential health and anti-aging properties. Antioxidants work by preventing oxidation reactions that produce free-radicals which can cause harm to the body. Try testing different vitamins for antioxidant activity. How do vitamins A, B, C, and E compare? Do some vitamins have more antioxidant activity than others? What are some other sources of antioxidants? Try testing extracts from proposed sources of antioxidants like coffee, tea, tomatoes, carrots, grapes, and berries (MedlinePlus, 2006). Do nuts contain antioxidants? Does roasting or processing affect the antioxidant properties of nuts? (Hopkins and Watts, 2003) A simple way to test for antioxidant activity is to see if the reagent can keep an apple slice from browning.

Ever wondered who plans the school lunch, food for patients at a hospital, or the meals for athletes at the Olympics? The answer is dietitians and nutritionists! A dietitian or nutritionist's job is to supervise the planning and preparation of meals to ensure that people—like students, patients, and athletes—are getting the right foods to make them as healthy and as strong as possible. Some dietitians and nutritionists also work to educate people about good food choices so they can… Read more

Growing, aging, digesting—all of these are examples of chemical processes performed by living organisms. Biochemists study how these types of chemical actions happen in cells and tissues, and monitor what effects new substances, like food additives and medicines, have on living organisms. Read more

Some patients prefer to treat certain medical problems without the use of medications, surgery, or other traditional therapies. Chiropractors diagnose and treat problems involving the muscles, skeleton, and nervous system using alternative therapies, such as manipulation of the spine and joints, acupuncture, massage, bracing, and heat therapy. They also counsel patients on how to achieve good overall health through diet, exercise, stress management, and rest. They try to treat the patient as a… Read more
Career Profile
There is a fraction of the world's population that doesn't have enough to eat or doesn't have access to food that is nutritionally rich. Food scientists or technologists work to find new sources of food that have the right nutrition levels and that are safe for human consumption. In fact, our nation's food supply depends on food scientists and technologists that test and develop foods that meet and exceed government food safety standards. If you are interested in combining biology, chemistry,… Read more
