QUES: Most fatty acids are non-essential, meaning the body can produce them as needed, generally from other fatty acids and always by expending energy to do so. However, in humans, at least two fatty acids are essential and must be included in the diet. An appropriate balance of essential fatty acidsomega-3 and omega-6 fatty acidsseems also important for health, although definitive experimental demonstration has been elusive. Both of these "omega" long-chain polyunsaturated fatty acids are substrates for a class of eicosanoids known as prostaglandins, which have roles throughout the human body. They are hormones, in some respects. The omega-3 eicosapentaenoic acid (EPA), which can be made in the human body from the omega-3 essential fatty acid alpha-linolenic acid (ALA), or taken in through marine food sources, serves as a building block for series 3 prostaglandins (e.g., weakly inflammatory PGE3). The omega-6 dihomo-gamma-linolenic acid (DGLA) serves as a building block for series 1 prostaglandins (e.g. anti-inflammatory PGE1), whereas arachidonic acid (AA) serves as a building block for series 2 prostaglandins (e.g. pro-inflammatory PGE 2). Both DGLA and AA can be made from the omega-6 linoleic acid (LA) in the human body, or can be taken in directly through food. An appropriately balanced intake of omega-3 and omega-6 partly determines the relative production of different prostaglandins, which is one reason why a balance between omega-3 and omega-6 is believed important for cardiovascular health. In industrialized societies, people typically consume large amounts of processed vegetable oils, which have reduced amounts of the essential fatty acids along with too much of omega-6 fatty acids relative to omega-3 fatty acids.

What does it mean when it is claimed that many fatty acids are non - essential?

QUES: Asked about the liberal, non-democratic rule by a Chilean interviewer, Hayek is translated from German to Spanish to English as having said, "As long term institutions, I am totally against dictatorships. But a dictatorship may be a necessary system for a transitional period. [...] Personally I prefer a liberal dictatorship to democratic government devoid of liberalism. My personal impression and this is valid for South America is that in Chile, for example, we will witness a transition from a dictatorial government to a liberal government." In a letter to the London Times, he defended the Pinochet regime and said that he had "not been able to find a single person even in much maligned Chile who did not agree that personal freedom was much greater under Pinochet than it had been under Allende." Hayek admitted that "it is not very likely that this will succeed, even if, at a particular point in time, it may be the only hope there is.", he explained, however, "It is not certain hope, because it will always depend on the goodwill of an individual, and there are very few individuals one can trust. But if it is the sole opportunity which exists at a particular moment it may be the best solution despite this. And only if and when the dictatorial government is visibly directing its steps towards limited democracy".

What did Hayek claim to prefer over a democratic government in the absence of liberal ideals?
What is the answer?
ANS: a liberal dictatorship
