Super food


Leo
According to the listening, super foods have no magic powers to reduce disease in humans. This casts doubt on information provided in the reading.
First, the professor mentions that the research about the blueberries doesn’t provide evidence it’s good for human’s brain function, because the research was only done on animals, such as rats and mice. It was not done on humans. On the other hand, according to the reading, blueberries are good for our brain cell communication and protect our brain cells from harm.
Second, the lecturer points out that the evidence about super food can’t insure a person won’t get cancer. For example, it’s true that the vegetables can give us nutrients like other vegetables and fruits, but it doesn’t provide evidence they can prevent cancer. However, according to the reading, we know these vegetables are shown to diminish the danger of the prostate and colon cancer .
Finally, the speaker states that garlic doesn’t help lower cholesterol. Garlic only works for the first three months, but the effect disappears after six months. In contrast, garlic can lower the high cholesterol and cure the common cold.
In conclusion, the listening tells us that information from the reading is not all correct, because it lacks strong evidence and most of it contains misleading statements.
