Green tea 10 g +1.26 years
What is your first memory of a cup of tea? On a trip to Japan, I got to experience a Japanese tea ceremony in Kyoto on the tatami mat in the tea house in a stripped stone garden. There, nature, tea cups, and architecture merged into respect for the tea plant and the body. The artist and monk Sen no Rikyu created the tea ceremony. It shows the principle of sabi and wabi – the aesthetics of the inner light of things. Watching the tea leaves unfurl in warm water is like watching spring break out in real-time.
In our latitudes, the tea plant does not grow naturally, and when I fell for tea, plans came to start a tea brand with newly planted tea plants in the Skåne countryside. Instead of a vineyard, I thought of setting up a Scanian tea plantation. But after the challenges at Eskelhem, Gotland, where
hundreds of tea plants were planted, I realized that in Europe, only the Azores and Georgia have a climate suitable for the tea plant.
There is already green, organic, and reasonably hand-picked tea for us to enjoy - the task becomes to weave the five cups (which, in studies, gave maximum health effects) into everyday life. The culture we grow up in gives us drinks and habits. Can we add green tea as a baton for the next generation?
Let a cup of tea warm you from the inside on cold days, and a glass of cold tea from the fridge cool you down on hot days. After water, tea is the most common human beverage, with over 3,000 varieties worldwide. Try your way to your favorite. Jasmine, bergamot, vanilla, cardamom - you could invent a new variant that can bear your name.
Tea merchant Thomas Sullivan invented The tea bag in New York in 1908 when he began sending tea samples in small silk bags to his customers. The jewelry company Boodles sold the world’s most expensive tea bag with 280 diamonds for $15,250.
Carl von Linné gave tea the Latin name Camellia sinensis – Camellia from China. Linné tried to bring home and plant tea plants in Sweden. After 19 years of trying, fourteen live tea plants arrived at the port of Gothenburg in 1764 with the ship Finland. Once in Uppsala, the Chinese plants and the dream of Swedish tea plantations withered.
The camellia genus is known for its white, pink, red, and yellow flowers. The camellia bush is green all year round and, in nature, can become a 20 m tall tree. The tea bush yields 70 kg of finished tea per year, and its top two leaves and the new shoots are picked every five to ten days.
It is said that tea was invented in China by Emperor Sheng Nung in 2737 BC. To stay healthy, the Emperor had the water boiled before drinking it. One day, on a picnic, the Emperor rested under a tree when the water was boiled.
A few Camellia sinensis leaves fell from the tree into the warm water and created new taste sensations for the Emperor (nicknamed the Divine Physician) – as he drank the world’s first cup of tea.
The excavation of the Han Emperor Jing’s (188 BC–141 BC) tomb in Xi’an yielded archaeological finds in the form of the world’s oldest tea leaves, traditionally dried to brew tea. The first book about tea was written by Luh-yu in 780. From China, where tea is seen as a symbol of earthly purity, tea culture spread to Japan in 805 and then to India and Indonesia.
The largest tea producers in a million tons of tea are China with 2.97, India with 1.2, Kenya with 0.43, Sri Lanka with 0.34, Vietnam with 0.21, and in tenth place is Japan with 0.08.
The first delivery of tea came to Sweden in 1685 from China. Eight of the East India Company’s 132 expeditions loaded with tea sank or ran aground. The ship Göteborg sank with 350 tons of tea in front of Karlsborg fortress.
Positive effects: A study of 100,902 Chinese people found that those who drank tea regularly lowered their risk of death from heart attack and stroke by 22%. Compared to those who rarely drank tea, regular tea drinkers lived an average of 1.26 years longer. After 5-8 years, the group was followed up. Those who drank tea regularly had then reduced the risk of death from stroke and heart attack by 56% and death from all causes by 29%. Heart-protective polyphenols (antioxidants) in green tea protect best through regular tea drinking. Tea is a hug in a cup.

For eleven years, 40,530 Japanese people were followed, and it was found that the Japanese who enjoyed at least five cups of green tea per day had a reduced risk of dying. The risk of death from all causes was reduced by 12% in men and 23% in women. Lower risk of death from heart disease: 22% in men, 31% in women. Lower risk of death from stroke: 35% in men, 42% in women.

The risk of breast cancer was 20-30% lower in the women who drank the most tea,(Breast cancer research and treatment. January 2010: Green tea consumption and breast cancer risk or recurrence: a meta-analysis) and tea drinkers had a 42% lower risk of colorectal cancer, (Oncotarget. June 2017: An inverse association between tea consumption and colorectal cancer risk) studies showed. In studies, green tea has lowered the risk of stomach cancer and advanced prostate cancer.

According to one study, four cups of green tea per day reduced body weight and waist size. (Ying Lin. May 2020: The effect of green tea supplementation on obesity: A systematic review and dose–response meta-analysis of randomized controlled trial) 3-4 cups of tea reduces weight in those with obesity. (Chung S. Yang. December 2015. Mechanisms of Body Weight Reduction and Metabolic Syndrome Alleviation by Tea) Research shows that green tea reduces abdominal and body fat, weight, and waist circumference in tea drinkers - helping one burn 75-100 calories daily.

A study over 5.7 years with 13,645 Japanese showed that green tea significantly lowered the risk of dementia. A research project showed that Parkinson’s was delayed by 7.7 years in those who drank more than 3 cups per day. A health study showed that increased consumption of 2 cups per day lowered the risk of Parkinson’s by 26%. (Age Ageing.

Research shows that caffeine improves brain functions - memory, alertness, reaction time, and mood. (Nutrion Bulletin. Volume33, Issue1 March 2008 Pages 15-25. The impact of caffeine on mood, cognitive function, performance and hydration: a review of benefits and risks) L-theanine in green tea increases the neurotransmitter GABA with an anti-anxiety effect. Green tea increases dopamine and alpha waves in the brain. (Asia Pac J Clin Nutr 2008;17 (S1):167-168. Anna C Nobre: L-theanine, a natural constituent in tea, and its effect on mental state.

Tip: Tea trains one to balance the sense of smell and taste in perfect cooperation. Green tea is the most common tea in Asia, and in Japan, it is often drunk with food. After harvesting, the leaves are heated directly, meaning the green color and beneficial antioxidants are retained. In China, the leaves are roasted in frying pans; in Japan, the leaves are steamed before being dried.
Make green tea by heating cold water to 75-80 degrees. Allow 2 g per cup to infuse for 1-3 minutes. Green tea leaves can be reused 3-4 times with different flavors unless the leaves dry out. The second brew is considered the best.
Cut a piece of lemon and add to the tea for extra vitamin C. Buy organic tea - a test found 15 pesticides in regular tea. Tea is stored in a dry, odorless, and dark place - for example, in a clay pot. For solution, whole or larger pieces of the leaf are used. You get the best flavor if the tea leaves move freely in the water.
If you use a ball or tongs, only fill it halfway as the tea expands in the water. The tea leaves are finely divided in tea bags, and the quality is low. Do not twist the tea bag; the tannic acid will taste bitter.
Cold brewing green tea is easy and allows you to brew a lot at once, providing more antioxidants and 33-50% less caffeine. Cold water extracts the flavors more slowly, giving a smooth, sweet, and aromatic taste with less risk of the tea becoming bitter. Put 10 g of green tea in 1 liter of water and let it steep for 8 hours in the refrigerator. The tea will last three days in the fridge.
