1 . In 1670, two Scottish doctors set up a garden in the city of Edinburgh to find out connections between plants and medicine. That first garden wasn’t very big — about the size of a tennis court. Fast-forward 350 years, and the Royal Botanic Garden Edinburgh (RBGE) now covers an area bigger than 1,000 tennis courts. The RBGE’s goal is to “explore, conserve and explain the world of plants for a better future”.
After doctors and distant cousins Robert Sibbald and Andrew Balfour graduated from university in the mid-17th century, they shared the goal of improving Scottish medicine by looking into botanical (plant-related) research. They found some land near Holyrood Abbey in Edinburgh and started to collect plants. They taught students how to grow exotic (外来的) plants and use them to make medicines. As the collection expanded (增加), the garden moved to different sites, including what is now Edinburgh’s Waverley Station.
In 1823, the garden was moved to its current location in Inverleith, a suburb of Edinburgh. It took three years to move the collection of plants and trees using specially built machines. The Tropical Palm House was built in 1834, and it was joined by the larger Temperate Palm House in 1858. Both are still popular with visitors. Throughout the 19th and 20th centuries, the RBGE continued to search for new specimens (标本) from around the world.
The RBGE has about 13,500 species of living plants in its collection today. The herbarium — a collection of dried and protected species — includes more than three million plant samples, which represent more than half of the world’s known plants. The oldest specimen dates back to 1697. Experts continue to recognize new species each year, as well as growing plants that are extinct in their own habitats. The RBGE also works with botanical gardens around the world, including in Africa and South America, and supports them with conservation projects, education and training.

2 . Feed your mind
We have known about the link between what we eat and our physical health for a long time.
The Mental Health Foundation produced a report called “Feeding Minds”. The report states that the brain is a physical part of our body that needs the correct food to work properly, just like the heart. The food should contain carbohydrates (碳水化合物), vitamins and fish oil.
There is also research that shows how a good diet can improve the behavior of children and their concentration. Daniel Brown is the head teacher of Barnet School.
With regard to serious mental illnesses Jacka and Sanchez-Villegas say that eating fruit, vegetables and fish helps to prevent depression.
However, many medical professionals feel that the research by Jacka and Sanchez-Villegas is too early.
The research recommends that people eat particular food for particular mental health issues. To improve your memory, eat salmon and nuts. To improve your concentration, eat vegetables.
Overall, it seems clear that we need to eat healthy food for our mind. Although we do not fully understand the link between the two, we suggest that we choose this as an important topic for publicity.
