An Essential Guide To Tea And Health
Ever since Chinese folklore told tales of leaves from an overhanging Camellia Sinensis plant that fell into Emperor Shennong’s cup of boiling water in 2737 B.C, tea has been known by cultures around the world for its power to soothe, restore and refresh. Far from being a fictitious promise, tea has been extolled for a myriad of potential health advantages, from reducing heart disease to even improving dental health and aiding weight loss.
Tea is undoubtedly an excellent source of nutrition for your health. First thing’s first. Make sure that your “tea” is indeed tea. True tea is derived from the Camellia Sinensis plant and has four main varieties, which are green, black, white and oolong. Herbal teas are an infusion of a different plant and isn’t technically tea.
Read on to find out why this amazing cup of goodness has potentially incredible health benefits.
Tea And Your Heart
According to the Academy of Nutrition and Dietetics, the antioxidants found in tea are the strongest evidence that attributes to good health of your heart. You can help increase your daily antioxidant intake by drinking tea, widely known to be rich in a particular group of antioxidants called flavonoids. For example, there is about eight times the amount of ‘anti-oxidant power’ in three cups of tea than there is in one apple. Research focused on the relationship of black tea consumption and heart health reported decreased incidences of heart attacks. Drinking green tea was linked to lower total cholesterol, LDL, triglycerides and higher HDL, which are the good cholesterol levels. It might also help protect against cardiovascular and degenerative diseases. Who’d have thought something that tastes that good can help maintain your health!
Green does not always have less caffeine that black tea. The amount of caffeine content may vary depending on the plant varietal, processing, and brewing methods. According to research, the caffeine content of green tea ranges from 24-40 mg per cup and black tea ranges from 14-61 mg per cup. Both green and black contain antioxidants that a fantastic for health. Studies have shown that black tea has similar property benefits as well. In each case oxidation or non-oxidation gives the tea a different set of antioxidant compounds.
Tea And Your Teeth
The Academy of Nutrition and Dietetics stated that in 2010, Japanese researchers reported that at least one cup on green tea per day was associated with considerable decreased odds of tooth loss. Other research has states that tea may lower the PH level of the tooth’s surface, which suppresses the growth of periodontal bacteria.
Tea And Your Weight
Studies that used tea extracts showed evidence of tea as a weight-loss aid. Though these results may not be directly applicable to brewed tea consumed in normal amounts, as stated by the Academy of Nutrition and Dietetics. In another study, participants who regularly consumed hot tea had a lower waist circumference and a lower BMI than non-tea drinkers. Scientists speculate that drinking tea regularly lowers the risk of metabolic syndrome (which increases the risk of diabetes, artery disease and stroke). It’s also essential to keep in mind that correlation does not always equal causation.
