Because the body converts all dietary sources of vitamin A into retinol, 1 mcg of physiologically available retinol is equivalent to the following amounts from dietary sources: 1 mcg of retinol, 12 mcg of beta-carotene, and 24 mcg of alpha-carotene or beta-cryptoxanthin.
The body needs more omega-3 than omega-6 to reduce the risk of heart disease and inflammation. Since olive oil is higher in omega-3 than other oils, sardines in olive oil contain more omega-3 than sardines in water; however, the sardines in water are still the better option with lower amounts of cholesterol and fat.
Sardines contain a variety of vital nutrients. Theyâre packed with heart-healthy omega-3 fatty acids, and theyâre a natural source of vitamin D, which is typically obtained from enriched foods. In spite of the benefits, whether canned sardines are good for you depends on one deciding factor: portion control.ven though they're low in total fat, sardines are a good source of omega-3 fatty acids. These fatty acids lower levels of cholesterol and triglycerides in your blood.
