Salt is a part of our daily life nowadays. Salt is everywhere, in our food, in our water, even in our body. It is common knowledge that salt brings various benefits to our health. Salt provides many kinds of elements that helps us to control blood status and become healthier. However, obtain too much salt actually brings disadvantages to our bodies. Many researches have been made to testify what exactly consequences bring by having too much salt.

In this article from popsci, author illustrates the general information about salt including the advantages and dangers of salt, how salt changes our health level and what functions salt has. Then the author mentions that eat too much salt can leads to high blood pressure, dehydration, and even negatively affect cognition function. In order to prove these points, the author lists an experiment which scientists make conclusion from observation. Another hypothesis mentioned in the article is how salt brings on stomach ulcers, infections, and may even hasten stomach cancer.

Although this article is listed in the popular science section, there are lots of places that the article should improve in order to make it more convincing. When puts out the evidence that state too much salt leads to cognition function damage, the author only mentioned an observational experiment which lacks of data and can be easily affected by third variables or chance. The following paragraph started with “the evidence is clear” though shows the correct statements but the “evidence” is not as clear as described in the article. In conclusion, this article is not scientific at all for it lack of data and comprehensive experiments representation.

Compare with this, another article on science daily, the author shows an experiment made by scientists who find out the relationship between high blood pressure and over salt consuming by measuring people’s rate of sodium in the urine and their consumptions of salt. Although this experiment is still an observational one, but overall it is better than the other one. At least the basic data is provided to make it seems more completed and analysis as well.

In order to write a more scientific science article, one should provide as many details of the researches or experiments as he can to prove their hypothesis. In the first salt article, the author fails to do this which makes his argument less convincing while the second one is more trustable.
