Different Types of Fish: What to Eat and What to Avoid

Different Types of Fish to Eat
Fish is a versatile meat, that goes well with any kind of spice, and thrives in regions worldwide, where each one has their own way of preparing the dish. It is key to know which fish can be eaten often, and which ones to cut down on, to avoid future health problems. The fish that are edible, are packed with vitamin A and vitamin D, and contain calcium that is good in making bones stronger.

Fish are a healthy source of protein, and omega-3 fatty acids, that aid in keeping our health and heart in check. Not all fish can be eaten on a daily basis, and one must know which fish are okay to eat often, and which aren't. Fish and shellfish are two food items that are rich in omega-3 fatty acids, minerals and vitamins. There are three types of fish that are edible - shellfish, white fish and oily fish. These contain omega-3 fatty acids, and can be eaten by pregnant women, or those that are breastfeeding, since it helps develop the baby's nervous system. White fish is a great source of omega 3 but not as much as oily fish. It's a great low-fat food that one can eat to even aid in weight loss.

When it comes to eating fish, there are portions that one must stick to in order to steer away from health related issues. One needs to eat more of omega-3 enriched fish, that is, oily fish, more often, although there is a portions limit. Girls and women who are expecting to have babies in the future, or those who are already pregnant/breastfeeding, can have two portions (twice a week) of oily fish, which is approximately 140 g a portion. Those girls and women who aren't expecting to have kids in the future, can incorporate four portions of oily fish in their diet (four times a week); the same applies for men/boys.
The Mercury Content in Fish
Mercury is a poisonous and toxic element, that is found in fish. Too much of it causes damage to one's system over time, especially to those who are pregnant/breastfeeding since it can damage the fetus/baby. Women who are pregnant, as well as toddlers, can eat 2 - 3 servings of fish a week, which is not more than two ounces, of low mercury content fish. Pregnant women/small children should stay clear from moderate mercury content fish.

Three servings/less per month of high mercury fish is sufficient, but pregnant women/small kids cannot eat these, while others can. Here we list out the types of edible fish that you need to go easy on in terms of mercury content, along with other kinds of fish that are safe to eat often. Keep in mind, that fish with way too much mercury in it, has to be absolutely avoided. These fish are not edible, and do not come under the safe fish to eat.
