Nutrition education in schools once promoted daily consumption of food from each of the "four food groups": milk, meat, fruit and vegetables, and breads and cereals. This recommendation was, however, dangerous to health. Each of the following, if true, provides support for the critique above EXCEPT: ['A healthy diet should include the consumption of several different fruits and vegetables daily, but the recommendation was often interpreted as satisfied by the consumption of a single serving of a fruit or vegetable.', 'The recommendation that some food from the fruit and vegetable group be consumed daily constituted a reminder not to neglect this group, which provides needed vitamins, minerals, and fiber.', 'The omission of fish, which contains beneficial oils, from the names of groups in the list gave erroneous impression that it is less healthy as a food than is red meat.', 'The division into four groups gave the impression that an equal amount of each should be consumed, but milk and meat tend to contain fats that promote heart disease and cancer and should be eaten in lesser amounts.']
