After puncture, it is light yellow to reddish brown transparent oily liquid with pure color and no impurities; The rubber skin is light yellow or reddish brown with bright luster, and the capsule skin can be dissolved in warm water at 70-80℃.
High-quality fish oil soft capsules should have a faint fishy smell after being bitten. If there is no fishy smell, it is a fake and shoddy product. If high-quality fish oil and ordinary fish oil are put in the refrigerator for more than 30 minutes at the same time, ordinary fish oil will solidify and freeze below zero degrees Celsius, while high-quality fish oil has good fluidity.
Dietary Guidelines for China Residents suggest that ordinary adults should eat 75-100g of fish and shrimp every day. However, considering the enrichment of heavy metals and environmental hormones in fish, it is suggested that eat small fish, such as salmon, has less pollution than sharks. Cooking methods should be boiled and roasted as much 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.
Although unsaturated fatty acids contained in deep-sea fish oil are very important to human body, we don't have to. Fish oil can only provide a single fatty acid. Although eating fish oil regularly can supplement DHA and EPA, if other nutrients are not enough, DHA and EPA can be easily converted into energy and quickly consumed. In this way, eating fish oil alone is not very helpful to human health.
