TEA / COFFEE DISADVANTAGES
THE DISADVANTAGES OF TEA
If you love waking up to a cup of hot tea, keep on sipping. This beverage is high in antioxidants, and research shows it may help prevent heart disease, build stronger bones and even improve your mood, according to Harvard Health Publications. Tea isn’t perfect, however, and does sometimes come with side effects. These issues are linked to true teas, which come from brewed tea leaves, and not necessarily herbal versions.
Tea contains antioxidants called flavonoids, which provide many of the health rewards. Flavonoids, however, bind to the nonheme iron found in plant foods such as beans and vegetables as well as dairy products. If you drink your tea with these foods, therefore, your body may not be able to access some of the iron. To maximize absorption of this important nutrient, limit tea drinking to between meals only, or add a spritz of lemon to help counter the iron-binding effect.
It doesn’t have as strong a kick as coffee, but tea does contain caffeine, which can make you nervous, jittery and nauseated and cause irregular heartbeats and insomnia. Although content varies by brand, black tea typically contains the most caffeine, oolong has moderate caffeine content, and green and white teas contain the least caffeine. Caffeine levels in tea may range from 14 to 60 milligrams per cup, which is far less than the 200 to 300 milligrams per day that MedlinePlus considers moderate intake. However, it may not take much caffeine for some people to experience negative effects.
Plain tea doesn’t contain any sugar or calories, but many bottled iced teas on the market are loaded with both. One major brand’s sweetened tea provides 50 calories per cup, while another’s has 90 calories per cup — with all of those calories coming from added sugar. Despite the calorie load, sugar has no nutritional value, and the American Heart Association recommends that women get no more than 100 calories — and men get no more than 150 calories — from added sugar each day.
While tea’s rich color may look lovely in your teacup, you probably don’t want your smile to match the hue. Unfortunately, tea can stain your teeth just like coffee, red wine and other colorful beverages. If staining is a concern, brush your teeth often — ideally, immediately after finishing your tea. It may also help to drink water after your tea to rinse away the staining agents.
While everybody seems to drink coffee, here are among the main reasons why we should limit the intake of coffee and stimulating drinks such as tea, chocolate and soda.
The main culprits in all of these are the caffeine. Here what caffeine does to our body:
1. Caffeine Is Highly Addictive
Like other drugs, caffeine causes a chemical addiction within the brain. Quitting coffee or soda can create withdrawal symptoms – headaches, sleepiness, irritability, anxiety – while the brain’s chemistry readjusts.
2. Caffeine Increases Stress Levels
Drinking four or five cups of coffee a day makes the body act as if it is under constant stress. Combined with additional work pressures, it can increase blood pressure significantly, leading to an increased risk of long-term heart disease, says a US report.
3. Caffeine accelerates Aging and Wrinkles
Caffeine contributes to the decline in production of hormones produced in abundance during youth – DHEA, melatonin, and others – which speeds the aging process. Because caffeine dehydrates the body, skin loses water from its cells, causing wrinkling and sagging.
4. Caffeine Accelerates Bone loss
Caffeine causes the urinary excretion of calcium, magnesium, potassium, iron, and trace minerals, which can lead to osteoporosis.Some women are more likely to be affected by caffeine than others due to genetic factors; however, it seems prudent to recommend that all older women have adequate dietary calcium, and limit caffeine intake to no more than 300 milligrams per day.
5. Caffeine Causes the Mood Swings
Mood disturbances such as anxiety, depression, irritability, and attention disorders are aggravated by chronic caffeine consumption. Rather than increasing mental activity as many caffeine drinkers believe, caffeine actually decreases blood flow to the brain by as much as 30% and negatively impacts memory and mental performance. Mood disturbances may appear after the stimulant effect of caffeine wears off – often about three hours later prompting many to consume more caffeine and they may also appear during the recovery period after quitting caffeine.
6. Caffeine Disturbs Normal Sleep Patterns
Because it is a stimulant, caffeine keeps you awake longer, thereby shortening the amount and the quality of sleep each night, which takes a toll on your level of alertness the next day and overall health. Because of sleep deprivation and fatigue, a person might look to caffeine for a boost, thereby perpetuating the vicious cycle.
Excess caffeine in the body causes anxiety, restlessness, insomnia, headaches, muscle tremors, gastrointestinal problems, diarrhea, nausea and irregular heartbeat.
So, dear readers, considering the effect of caffeine to our body please choose your drinks wisely from now on. A good substitute will be a good herbal tea that does not contain caffeine at all.
