The Difference between Tea and Coffee

Tea and coffee are the two most popular beverages in the world, and both have huge consumer groups.
Today we want to talk about the difference between tea and coffee from the perspective of health, what are the benefits of each, and which one is healthier to drink?
Both tea and coffee are considered good for health, and there is plenty of research to back this up.
Studies have found that tea contains tea polyphenols, theaflavins, tea polysaccharides, caffeine and amino acids and other components with biological effects. For example, amino acids can replenish energy and improve the body’s immunity; tea polyphenols and tea polysaccharides have the effects of lowering blood pressure, lowering lipids, and lowering blood sugar, which can reduce the risk of cardiovascular disease; caffeine can refresh the mind, promote the metabolism of brain cells, etc. In addition, drinking tea can help prevent cancer and help delay aging.

Health benefits of drinking coffee

Modern research has found that the biologically active ingredients in coffee are mainly caffeine, chlorogenic acid, trigonelline, and diterpenes. Studies have shown that drinking coffee properly can also prevent and reduce the risk of cardiovascular disease. In addition, a large prospective cohort study from more than 20 countries in the United States, Asia, Europe, etc. showed that the risk of type 2 diabetes was inversely related to coffee consumption. Compared with people who did not drink coffee, those who drank 2 to 3 cups of coffee a day and those who drank more than 3 cups of coffee a day were 23% and 26% less likely to develop diabetes, respectively.
Also, coffee has been found to reduce the risk of colorectal cancer, hepatocellular cancer, lung cancer, stomach cancer, and skin melanoma. Its caffeine content is also higher than tea leaves, so it can also be used to prevent neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease.

Tea and coffee, which one is healthier?
From the above point of view, drinking tea and drinking coffee are both helpful for health, but there are few research reports on which one is healthier. In terms of its association with atherosclerosis, some studies have found that drinking green tea may be a protective factor for atherosclerosis, however, the results of coffee in preventing atherosclerosis are inconsistent, so from the perspective of cardiovascular protection, tea should be better.
In addition, in terms of protecting the kidneys, both tea and coffee have a certain diuretic effect. On the one hand, both can produce osmotic diuresis by increasing the intake of water. On the other hand, the caffeine contained in the two also has a certain diuretic effect. Therefore, it can promote the excretion of toxins in the body, eliminate edema, and prevent kidney stones.
However, because the caffeine content in coffee is higher than that in tea, and caffeine has an excitatory effect, coffee should not be drunk in large quantities, otherwise it will easily lead to mental hyperactivity, insomnia, etc., while the caffeine content in tea is lower, so you can drink more tea than coffee, and the diuretic effect is stronger than coffee.
Both coffee and tea contain different types of polyphenols, which are powerful antioxidants that protect against heart disease and cancer. Both coffee and tea can give people an energy boost, but in different ways.

The effect of tea on energy
Although tea is low in caffeine, it is rich in L-theanine, a powerful antioxidant that also stimulates the brain. Unlike caffeine, L-theanine can provide anti-stress effects by increasing the brain's alpha-waves, which help calm and relax. This counteracts the stimulant effects of caffeine, giving a relaxed but alert mental state without feeling lethargic.
Studies have found that, like drinking tea, consuming L-theanine and caffeine can help people stay alert, focused, and sharp. This combination may be why tea gives people a more soothing and smoother energy boost than coffee.

The energy boosting effect of coffee
The caffeine in coffee boosts the body's energy levels, increases alertness and reduces fatigue by increasing dopamine levels and blocking adenosine. Dopamine is the chemical messenger responsible for the stressful effects of coffee as it increases the body's heart rate. It also affects your brain's reward system, increasing the addictive nature of coffee. On the other hand, adenosine has the effect of promoting sleep. Therefore, caffeine reduces fatigue by blocking it.
In the end, whether it is tea or coffee, it is healthier than drinking sugary beverages. Whether it is better to drink tea or coffee, the key is the right amount and the degree of tolerance to tea or coffee. For example, if a person can't fall asleep after drinking coffee, but not when he drinks tea, then there is no need to drink coffee reluctantly, and vice versa. Moreover, neither drinking tea nor drinking coffee can replace a healthy lifestyle, which also needs to be understood by everyone.
