In a move to expand its big meatpacking operations, the Occidental Petroleum Corporation said today that it was seeking to acquire the Wilson Foods Corporation for $95 million in cash. Wilson had been expected to emerge within weeks from bankruptcy proceedings. Occidental told the Federal bankruptcy court in Oklahoma City, where Wilson is based, that it would file an alternative to Wilson's plan for reorganization. A spokesman for Wilson refused to comment in detail on the proposal, saying that executives had not seen it.

Mayor Koch says in a new book that he was ''guilty of hubris'' in running for Governor in 1982 only months after being overwhelmingly re-elected to a second term at City Hall and recalls that ''in my heart, I knew that I really belonged in New York City.'' The book, titled simply ''Mayor,'' is a celebration of Mr. Koch's personality. It blends personal reminiscences, anecdotes about his friends and antagonists in public life, generous excerpts from his speeches and from newspaper stories about his exploits, and explanations of his relationship with municipal unions and minority groups. The book is to be published this spring by Simon and Schuster, and copies of uncorrected proofs have already begun circulating in the city's literary and political circles.

MOST people have long been aware of the potential dangers of high cholesterol. For more than a decade, the American Heart Association, later joined by more than a dozen health organizations, has been urging Americans to lower their blood cholesterol levels by eating less of the foods that are rich in cholesterol and cholesterol-raising saturated fats. But most Americans who heeded this advice at all did so only halfheartedly. The link between high blood cholesterol and premature heart disease was, after all, only statistical. It had yet to be shown convincingly that lowering cholesterol levels for a period of years would actually reduce the risk of heart attacks. Now, however, a Federally sponsored 10-year study has demonstrated conclusively that lowering cholesterol levels in the blood helps to prevent heart attacks. The study, a cooperative scientific effort conducted among 3,806 middle-aged men, all of whom had abnormally high cholesterol levels, showed that for every 1 percent reduction in cholesterol, there was a 2 percent fall in the rate of coronary heart disease.

P. Takis Veliotis, a former executive of the General Dynamics Corporation, has offered to provide information to Justice Department officials that he contends can prove that the company defrauded the Navy of hundreds of millions of dollars, persons familiar with the matter said today. In return, Mr. Veliotis, who is under indictment for Federal kickback charges, wants partial immunity from prosecution. But Government officials said today that the Justice Department was not inclined to make such a deal at this time. John H. Gross, a lawyer for Mr. Veliotis, who fled to Greece before he was indicted, said, ''I will not comment on pending negotiations between Mr. Veliotis and the Government.''

The Supreme Court ruled today that consumers do not violate Federal copyright law when they use video recorders to tape television programs for their own use. Neither, the Court held in a 5-to-4 decision, do companies that make and sell the machines violate the copyright law by making them available to the general public. The long-awaited decision was a major victory for the electronics industry, which has sold nine million video cassette recorders to American consumers. The industry, with more than $1 billion in yearly domestic sales of video recorders and tapes, had operated under a legal cloud since a 1981 decision by a Federal appeals court in California.
