When we make a new commitment to healthier eating, one thing we have to decide is what, exactly, that means. For some people it is as simple as basic adjustments like no junk food in the house or no fast food at lunch. But if you have relied heavily on processed foods for a long time, there can be a lot to learn about choosing fresh foods, storing them, and preparing them.
Fish is a good source of lean protein, highly recommended in part because of the Omega-3 fatty acid content in some fishes, but the ocean fisheries are stressed by pollution and heavy fishing, so eating more fish can bring up new questions. National Geographic has created this interactive tool that lets you make a few choices and gives you a list of fishes that comply with your preferences. Clicking on a fish pops up a window with more information about why that fish was ranked the way it was.
Marine science and ocean ecology have been key aspects of human success for millennia — as sources of food, as transport routes, and as a large factor in our climate and weather systems. If you want to learn more about these issues, try Southern Fried Science. SFS is heavily geared toward subjects of interest to people working in the field, but it also tackles issues important to consumers, like what all those food labels, like “Organic” and “Fair Trade”, really mean.
