Final answer:
Common food sources rich in omega-3 fatty acids include salmon, flaxseeds, and hemp seeds. These foods provide essential omega-3 fatty acids like ALA, EPA, and DHA, which are polyunsaturated and beneficial for health.
Step-by-step explanation:
Common Food Sources of Omega-3 Fatty Acids
Omega-3 fatty acids are essential fats that are important for brain function, growth and development, and may reduce the risk of heart disease and certain cancers. The common food sources rich in omega-3 fatty acids include cold-water fish and certain plant-based foods. Among the options provided, C) Salmon, flaxseeds, hemp seeds is the correct answer. These are well-known sources of alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), all of which are polyunsaturated omega-3 fatty acids.
Fish such as salmon, trout, and tuna are excellent sources of omega-3 fatty acids, specifically EPA and DHA which are directly used by the body. Plant sources such as flaxseeds and hemp seeds contain high levels of ALA, which the body partially converts to EPA and DHA. Walnuts and chia seeds, as mentioned in the second option, also contain significant amounts of ALA.
It's important to note that while olive oil, walnuts, and chia seeds are good sources of omega-3s, they are primarily rich in ALA rather than EPA and DHA. Avocado, sunflower seeds, and almonds provide healthy fats but are not particularly high in omega-3 fatty acids. Butter, beef, and cheese usually contain more saturated fats and are not considered good sources of omega-3s.
