Pescetarianism is a diet in that an individual eats any combination of vegetables, fruit, nuts, beans and fish or seafood, however will not eat mammals or birds. Some pescetarians eat eggs and dairy product, whereas others do not. The most recent Merriam-Webster Inc.'s dictionary includes a brand new entry pescetarian, that they outline as a "vegetarian whose diet includes fish." The word itself blends the Italian word "pesce" which means fish and also the English word "vegetarian". Most vegetarians don't eat fish and will not take into account pescetarians to be true vegetarians notwithstanding any dictionary or word origin.
Some pescetarians see their diet as a type of halfway house on the way to changing into a vegetarian or perhaps going vegan. They opt for not to "go all the manner" in one fell swoop. Many folks believe that eating fish is healthier than eating meat, which contains high levels of saturated fats. Eating some kinds of fish can raise your HDL (high-density lipoproteins) levels, and bear in mind that another name for HDL is "good cholesterol." Some people claim that HDL protects against cardiovascular diseases. Another profit of eating fish, particularly oily fish, is the increase in omega-three fatty acids, said by several to cut back the chance of coronary heart disease and cancer, in particular breast, colon, and prostate cancer. On the dark facet, fish could contain toxins like mercury and PCBs.
Some pescetarians feel that it's a lot of acceptable to kill and eat fish and seafood than to kill and eat land animals and birds. One argument consists in putting in a spectrum of animals running from microbes to primates, saying in effect that just about no one objects to killing microbes which fish are nearer to microbes than to us or our simian friends. Another argument states that the environmental impact of eating and perhaps raising fish and seafood is abundant less than the impact of raising cattle for market.
Several pescetarians claim that fish, unlike mammals and birds, cannot feel pain. The scientific jury continues to be out on this question. Most animals consumed in North America have been raised for market. On the other hand, most fish and seafood are free-range. Furthermore, fish and seafood require less food per edible pound than do animals and birds. So we have a tendency to may be "wasting" fewer calories of our hungry planet by eating fish and seafood.
A 2006 United Nation's Food and Agriculture Organization report entitled Livestock's Long Shadow estimates that livestock are responsible for roughly 18 % of the worldwide warming result, a greater contribution than caused by transportation. Livestock produce methane as half of their digestive method and their manure contains nitrogen. Furthermore, grazing land means that deforestation. A fish diet substantially reduces these global warming factors. However, overfishing has destroyed several natural habitats and fish-farming also has serious environmental impact.
