Sometimes too much of a good thing can become a very bad thing indeed. In an attempt to consume a healthy diet, dietary supplement fans have been known to overdose. Vitamin
C, for example, long thought to help people ward off cold viruses, is currently being studied for
its possible role in warding off cancer and other diseases that cause tissue degeneration.
Unfortunately, an overdose of vitamin C – more than 10,000 mg. – on a daily basis can cause
nausea and diarrhea. More than just a few grams a day, however, can lead to stomach upset and even kidney or bladder stones. Niacin, proven useful in reducing cholesterol levels, can be dangerous in large doses to those who suffer from heart problems, asthma, or ulcers.

The main idea expressed in this paragraph is:

A. supplements taken in excess can be a bad thing indeed.

B. dietary supplement enthusiasts have been known to overdose.

D. people who take supplements are preoccupied with their health.

E. None of the above.

A, supplements taken in excess can be a bad thing indeed.

Explanation:

Supplements taken in excess can be a bad thing indeed, because it also summarizes / concludes what is said at the being of the thesis

the support that the author, uses in the article facing our fears is a): a definition of the part of the brain called the amygdala.

he takes neuroscientist joseph ledoux's words by telling that by falling to distinguish between evolutionary old systems located in the amygdala and newer systems, centered in the prefrontal cortex, doctors have conflated non conscious threat circuits in the brain with circuits that underlie the conscious experience of fear. that, the author says, "leads ledoux to the jarring conclusion that the amygdala, a decades-old centerpiece of the brain's fear circuit, does not underlie the conscious feeling of fear".

despite this, the author points out in the article that that is a controversial notion and that evidence, in animal and humans, supports the idea that core emotions can exist outside of conscious awareness.

wow there were a thousand people in the concert. that’s great
