Super Power Foods

JOE
According to the listening, super foods have no magic powers to reduce disease in humans. This contradicts information provided in the reading. The professor states that superpower foods are exaggerated and far-fetched. On the other hand, according to the reading, superpower foods make human’s lives healthier by decreasing disease and providing more energy.

He gives 3 examples to support his opinion. First, he denies that blueberries affect human’s brains. He insists blueberries influence is on animals, not humans. However, as claimed by the reading, blueberries have a positive effect on brain functioning in people.
Second, the professor explains tomatoes can’t ensure people won’t get cancer. In contrast the reading makes it clear that tomatoes help lower cholesterol and reduces the risk of cancer.
Third, the speaker says it’s probably untrue that garlic helps lower cholesterol. He mentions it works for just 3 months, but afterwards the effect declines and disappears. However, according to the reading, garlic triggers a drop in LDL blood cholesterol.

In conclusion, according to the speaker’s comments, superpower foods such as blueberries, tomatoes, broccoli, cabbage and garlic can’t conclusively prevent human disease.
