Can the fish oil on a fish's body be eaten?
The fish oil found on fish is edible and rich in nutrients such as unsaturated fatty acids, which are beneficial to human health. However, it's important to choose fish oil from fresh fish and avoid excessive consumption.

The key nutritional component of fish oil is Omega-3 unsaturated fatty acids, including DHA and EPA. These substances help regulate lipid metabolism, positively support cardiovascular health, and assist in maintaining brain and retinal function. Moderate intake is suitable for most people.
Be aware that fish from polluted waters may accumulate heavy metals and harmful substances, posing safety risks with their oil; therefore, opt for species from cleaner environments, such as deep-sea fish. Additionally, fish oil is calorie-dense—excessive consumption may lead to excess caloric intake, so individuals with obesity should carefully control their portion sizes.
Select fresh, high-quality fish when consuming fish oil, and use light cooking methods such as steaming or boiling to preserve nutrients, avoiding high-temperature frying. It is recommended not to exceed 50 grams per day. Combining fish oil intake with a balanced diet rich in vegetables and grains will better maximize its nutritional benefits.
