Green tea and brain health -
Here are five possible benefits of green tea and how to incorporate it into your diet. One of the main ingredients in green tea is caffeine. Caffeine can block a chemical messenger in the brain called adenosine , which controls when you feel sleepy or awake.
Blocking adenosine can prevent drowsiness, which is why so many people use caffeine to stay awake and mentally sharp. An overproduction of adenosine in the brain has also been linked to cognitive conditions like Alzheimer's and Parkinson's. Research shows that regular consumption of caffeine may reduce the risk of developing these conditions.
The amount of caffeine in green tea is much lower than in coffee, so you can get some of the benefits of caffeine without the unpleasant side effects, like jitteriness.
Green tea also contains an amino acid called L-theanine, which has been found to help reduce stress and boost your mood. Research shows that the combination of caffeine and L-theanine improves brain function by strengthening working memory and attention, and reducing anxiety.
A small study observed the effects of drinking green tea on brain function, concluding that regular tea drinkers have higher cognitive functions and better-organized brain regions, as compared to non-tea drinkers. A review of 21 studies on the benefits of green tea also determined that drinking green tea is beneficial to cognition and brain function.
Green tea has been found to play a role in heart health by reducing the risk factors that cause heart disease. High blood pressure is one of the most common risk factors for heart disease. Research shows that consuming green tea significantly lowers systolic and diastolic blood pressure, which are the two different numbers by which a person's blood pressure is recorded.
Moreover, a very large long-term study published in followed two groups who had no history of heart disease. The first group was made up of people who drank green tea more than three times a week, and the second group was made up of people who never drank green tea, or didn't drink it habitually.
In a follow up about seven years after the start of the study, scientists found that those who drank tea regularly were likely to have 1. Catechin is a major component of green tea. Catechins are natural antioxidants that have antioxidative, anti-inflammatory, and anti-hypertensive effects.
They lower cholesterol levels by decreasing the absorption of cholesterol into the body. An analysis of 14 studies showed that drinking an average of two cups of green tea per day for 10 years resulted in significant reductions in LDL cholesterol levels.
LDL cholesterol is also known as bad cholesterol, because it can cause plaque buildup in your arteries, which increases your risk of getting a heart attack or a stroke. The mechanism for this isn't well-defined, though one theory is that epigallocatechin gallate ECGC , a compound of green tea, affects the circulation of bile acids, which helps to regulate cholesterol," says Ring.
Green tea also helps to keep your bones healthy and strong. Research shows that it may help treat and prevent osteoporosis, a condition that makes your bones weaker and more prone to fractures.
Flavonoids are and phytoestrogens are plant chemicals that can strengthen bone formation and prevent the breakdown of bone tissue.
In a study , postmenopausal women with weak bones and low bone mass were put into four groups. The results of the study showed that the group of women who were given compounds derived from green tea experienced a notable improvement in their bone health.
A study also concluded that green tea may benefit bone health, after examining bone-forming cells. The researchers exposed the cells to epigallocatechin EGC , gallocatechin GC , and gallocatechin gallate GCG , which are all main components of green tea.
They also observed that high concentrations of EGC disrupted the activity of osteoclast, a cell that weakens bones. Green tea contains a micronutrient called epigallocatechin gallate EGCG that may be responsible for green tea's skin repair properties. Some research shows that EGCG contains antioxidants , which help to prevent sun damage.
It also boosts skin hydration, moisture retention, and prevents wrinkle formation. Green tea has also been shown to have anti-aging properties.
A small study studied the effects of using oral supplements and applying green tea topically on aging skin for 8 weeks.
Researchers found that the combination of using green tea topically and orally in the participants caused an improvement in the skin's elasticity. Catechin, a polyphenol in green tea, also helps to soothe inflamed skin when used topically.
Green tea comes in different forms, but to enjoy the optimal benefits of tea, it's best to drink it plain. Some research suggests that adding milk may counteract some of the health benefits of drinking tea. It's important to note that green tea contains caffeine, so if you have a caffeine sensitivity, you might want to consume it in smaller amounts.
And research shows that L-theanine is helpful in relieving stress disorders, improving mood, and getting better sleep. The National Institutes of Health Center for Complementary and Integrative Health, notes that when green tea is consumed as a beverage, it's "believed to be safe when used in amounts up to 8 cups per day.
Still, green tea does have caffeine in it, a compound known for stimulating the central nervous system. Drinking too much caffeine can cause insomnia, headaches, dehydration, dizziness and dependency. Green tea has about 28 milligrams of caffeine in 8 ounces of brewed liquid or 19 milligrams in the same amount of a ready-to-drink bottled form, per the Mayo Clinic.
That brewed amount is significantly less than the 96 milligrams of caffeine per 8 ounces of brewed coffee, but more than the 22 milligrams of caffeine found in 8 ounces of Cola. Beyond being careful with green tea's caffeinated content, it's also wise to be mindful of empty calories from adding sugar and too many creamers to the beverage, says Naidoo.
