Nuts, vegetable oil and fish are rich sources of ________.

Omega-3

The correct answer is Option (1) - Omega-3

Nuts, vegetable oil, and fish are rich sources of Omega-3 fatty acids. Omega-3 fatty acids are a type of polyunsaturated fat that is essential for human health. They play a crucial role in brain function, reducing inflammation, and promoting heart health. These fatty acids are considered essential because the body cannot produce them on its own and must obtain them from the diet. Foods such as nuts, vegetable oils (like flaxseed oil and canola oil), and fatty fish (such as salmon, mackerel, and sardines) are particularly high in Omega-3 fatty acids.
