Example Input: Seafood is very healthy to eat -- all things considered. Fish and shellfish are an important source of protein, vitamins and minerals, and they are low in saturated fat. But seafood's claim to fame is its omega-3 fatty acids, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), all of which are beneficial to health. The U.S. Dietary Guidelines for Americans strongly suggest that adults eat two servings of seafood, or a total of eight ounces, per week. Omega-3s are today's darling of the nutrition world, and many observational studies have indeed shown them to benefit a range of conditions such as high blood pressure, stroke, certain cancers, asthma, Type 2 diabetes and Alzheimer's disease.Most Americans eat plenty of protein, but not enough of it is from seafoodAmid concerns over mercury pollution and sustainability, how do you choose?

Example Input: (CNN) For the first time, eight planets have been found orbiting a distant star, Kepler-90, 2,545 light-years from Earth in the Draco constellation, NASA announced Thursday. It is the first star known to support as many planets as are orbiting our own sun, and researchers believe that this is the first of many to come. Researchers had known that seven planets were orbiting the star. But Google Artificial Intelligence -- which enables computers to "learn" -- looked at archival data obtained by NASA's planet-hunting Kepler telescope and uncovered the eighth planet. With the idea of eventually differentiating among exoplanets, Christopher Shallue, senior software engineer at Google AI in California, and Andrew Vanderburg, astronomer and NASA Sagan postdoctoral fellow at the University of Texas, Austin, trained a computer how to differentiate between images of cats and dogs.For the first time, eight planets have been found orbiting Kepler-90It is tied with our solar system for a star hosting the most known planets
