The brain uses omega-3 polyunsaturated acids to build nerve cell membrane and for nerve cell signaling.
The fatty acid profile, especially the proportion of saturated to mono- and polyunsaturated acids, is of particular importance.
Analyzing the fatty acid profile of jambolan seeds (Syzygium cumini L.), Luzia and Jorge (2009) obtained 67.91% of the total unsaturated fatty acids, including 24.10% of monounsaturated fatty acids and 43.81% of polyunsaturated acids, with linoleic acid being the major component.
The extraction process, even though it involved high temperatures, did not promote the oxidation of polyunsaturated acids. The drying process, followed by extraction, yielded 7.6 g of omega-3 fatty acids per kg of fresh sample.
Keep fat intake to less than seven percent of daily calories, and eat two or more servings of fish per week (but not commercially fried fish filets), which provide omega-3 polyunsaturated acids.
What are your key findings in terms of the benefits of long-chain polyunsaturated acids (LCPUFAs)?
University of Pittsburgh researchers found that people with low blood levels of omega-3 polyunsaturated acids were more likely to report symptoms of moderate depression, have a negative outlook, and be more impulsive as measured on psychological tests.
Fish and shellfish also contain omega-3 polyunsaturated acids, which cannot be produced within the body.
Says White, "As a monounsaturated fatty acid, the third type, oleic acid has higher stability than the polyunsaturated acids. And it has good characteristics, similar to those of the polyunsaturated fatty acids, when it comes to prevention of cholesterol and heart disease."
In general, eating some fish is encouraged for all women, because it is a good source of protein and omega-3 polyunsaturated acids. Essential fatty acids are important for neurologic development.
