Because fish oil is easily oxidized, eating fish is more efficient than eating preparations. The dietary guidelines for China residents suggest that the average adult should eat 75- 100g of fish and shrimp every day. However, considering the enrichment effect of heavy metals and environmental hormones in fish, it is suggested that eating small fish, such as salmon, is less polluting than sharks.
Cooking methods should be cooked and roasted as far as possible, and frying will destroy its nutrition. People who don't eat fish can also consider supplementing omega-3 polyunsaturated fatty acids with flaxseed oil and nuts.
