Question: Modern separation techniques such as milling, centrifugation, and pressing have enabled concentration of particular components of food, yielding flour, oils, juices, and so on, and even separate fatty acids, amino acids, vitamins, and minerals. Inevitably, such large-scale concentration changes the nutritional content of food, saving certain nutrients while removing others. Heating techniques may also reduce food's content of many heat-labile nutrients such as certain vitamins and phytochemicals, and possibly other yet-to-be-discovered substances. Because of reduced nutritional value, processed foods are often 'enriched' or 'fortified' with some of the most critical nutrients (usually certain vitamins) that were lost during processing. Nonetheless, processed foods tend to have an inferior nutritional profile compared to whole, fresh foods, regarding content of both sugar and high GI starches, potassium/sodium, vitamins, fiber, and of intact, unoxidized (essential) fatty acids. In addition, processed foods often contain potentially harmful substances such as oxidized fats and trans fatty acids.
Is there an answer to this question: An unfortunate side effect of concentrating food components is that it causes what change in the food?

Answer: nutritional content

Question: As early as 1794, Lieutenant-Governor of New South Wales Francis Grose suggested its closure as a penal settlement, as it was too remote and difficult for shipping and too costly to maintain. The first group of people left in February 1805, and by 1808 only about 200 remained, forming a small settlement until the remnants were removed in 1813. A small party remained to slaughter stock and destroy all buildings, so that there would be no inducement for anyone, especially from other European powers, to visit and lay claim to the place. From 15 February 1814 to 6 June 1825 the island was abandoned.

Question: Nasser made secret contacts with Israel in 195455, but determined that peace with Israel would be impossible, considering it an "expansionist state that viewed the Arabs with disdain". On 28 February 1955, Israeli troops attacked the Egyptian-held Gaza Strip with the stated aim of suppressing Palestinian fedayeen raids. Nasser did not feel that the Egyptian Army was ready for a confrontation and did not retaliate militarily. His failure to respond to Israeli military action demonstrated the ineffectiveness of his armed forces and constituted a blow to his growing popularity. Nasser subsequently ordered the tightening of the blockade on Israeli shipping through the Straits of Tiran and restricted the use of airspace over the Gulf of Aqaba by Israeli aircraft in early September. The Israelis re-militarized the al-Auja Demilitarized Zone on the Egyptian border on 21 September.
Is there an answer to this question: What did Nasser eventually do in the Straights of Titan?

Answer: blockade on Israeli shipping

Question: Since the late 18th century, Paris has been famous for its restaurants and haute cuisine, food meticulously prepared and artfully presented. A luxury restaurant, La Taverne Anglaise, opened in 1786 in the arcades of the Palais-Royal by Antoine Beauvilliers; it featured an elegant dining room, an extensive menu, linen tablecloths, a large wine list and well-trained waiters; it became a model for future Paris restaurants. The restaurant Le Grand Vefour in the Palais-Royal dates from the same period. The famous Paris restaurants of the 19th century, including the Cafe de Paris, the Rocher de Cancale, the Cafe Anglais, Maison Doree and the Cafe Riche, were mostly located near the theatres on the Boulevard des Italiens; they were immortalised in the novels of Balzac and Emile Zola. Several of the best-known restaurants in Paris today appeared during the Belle Epoque, including Maxim's on Rue Royale, Ledoyen in the gardens of the Champs-Elysees, and the Tour d'Argent on the Quai de la Tournelle.
Is there an answer to this question: In what century was Cafe Anglais, Cafe de Paris and Rocher de Cancale opened?

Answer:
19th
