Energy
drinks and nutrition bars fall under the energy food category. As stated by
Kids Health.org, although producers often claim that energy foods help increase
energy, alertness and concentration, as well as enhance athletic performance,
they cannot replace the benefits of regular physical training and exercise,
proper nutrition and adequate periods of sleep and rest.
Energy
products and drinks contain significant amounts of sugar and caffeine, so like
other food items and dietary supplements, you should take them in moderation.
Central Nervous System Stimulant
Energy drinks contain caffeine, a
natural substance produced by leaves and seeds of various plants. MayoClinic.com
states that caffeine can stimulate the central nervous system, relieving
fatigue, improving concentration and increasing alertness. Caffeine also can
boost energy levels and enhance mood. Too much caffeine, however, can be
harmful; MayoClinic.com recommends that adults take approximately 200 to 300 mg
per day. A single serving of energy drink, 8 to 16 oz., might contain 80 to 160
g of caffeine.
Memory Improvement
Energy drinks containing ginkgo
extracts can help improve your memory and stimulate your thinking process.
According to Medline Plus, a website supported by the National Institutes of
Health, gingko extracts improves thinking and cognitive skills, especially in
elderly people. As a supplement, gingko enhances short-term visual memory and
speeds up mental processing. Gingko extracts also can help improve proper blood
circulation in your brain, eyes and ears.
Antioxidants
Some
energy drinks contain healthy herbs
and fruits, including acai berries. According to Medline Plus, acai berries are
harvested from the acai palm trees found in the rain forests of South America.
Acai berries have antioxidant properties that can effectively protect your
body's cells from the damaging effects of free radicals and oxidation.
Energy
Obtaining
energy remains the main purpose of taking energy drinks. Energy drinks contain ample amounts of sugar, and the breakdown of
sugar provides your body with the fuel needed to function properly, according
to the Centers for Disease Control. To avoid problems with high blood sugar
levels, drink energy drinks only in moderation.
