¶ … 1992, the U.S. Department of Agriculture proposed the food pyramid as a tool of assessing the healthiness of a diet and as a proposal towards healthy living. While many of the issues that were relevant in the 1992 USDA food pyramid, such as "eating a variety of foods," balancing foods with physical activity" or moderate consumption of alcohol -- general indications for a healthy lifestyle -- the actual reference to food and to what can actually be called a healthy diet has been a point of controversy ever since. We will be proposing three modifications to key points in the food pyramid, according to the reasoning presented here below.
The first issue is the failure of the USDA pyramid to "recognize important health differences between red meat"
and other foods in the group. The risk of consuming red meat is clearly related with increased risk of developing coronary disease, colon cancer or diabetes. However, the red meat category, including pork and beef, are predominant in saturated fat, which raises cholesterol and rises the risk of coronary disease. The generic category "meat products" is much too general, because chicken and fish, the so-called white meat category, produce more unsaturated fat, which lower consistently the risk of having the diseases I have previously mentioned here above. As such, it...
The old pyramid recommended that 2 to 3 servings for meat in general. In the new pyramid, we suggest that fish and poultry be used in 1 to 3 or even 4 servings, while the red meat category be used sparingly, due to increased risks of disease.
The second issue that needs debating refers to the role carbohydrates play in the old pyramid and the position we want to attribute them in the new one. In the old pyramid, carbohydrates, including bread, cereal, rice and pasta, were recommended in 6 to 11 servings. They were thus used as surrogate replacements of fats and as providers of necessary calories.
However, the food pyramid never considered some of the negative effects of carbohydrates and of consuming them in 6 to 11 servings. One of these would be the fact that a massive switch in one's diet from fats to carbohydrates increases the blood level of triglyceride, with increased chances of heart disease
. It would seem, in this case, that the old pyramid substitutes one source of heart diseases with another. Additionally, levels…

It is bordered to the north by Burma and Laos, to the east by Laos and Cambodia, to the south by the Gulf of Thailand and Malaysia, and to the west by the Andaman Sea and the southern extremity of Burma.

The growing number of New Yorkers lacking health insurance has been a persistent concern of government as well as the public. (309) In contrast, the distribution of health care resources came to the fore more recently. The New York State Commission on Health Care Facilities in the 21st Century, for example, recommended a series of hospital closures and downsizing, based primarily on financial considerations in 2006.

Legislative risks: The decision to provide healthier food by labeling the ingredients on the packages to include the calories, sugar, fat, sodium, and saturated fat content needs to also comply with the U.K. food and labeling law.

There are several kinds of scenarios. However, in this paper, we limit our discussion to the decision-driven and vision-driven scenarios as proposed in the work of Courtney (2003). We however extend this discussion to involve the three levels of performance as proposed by Rummler and Brache (1995). The argument of course is based on the general consensus that the vision-driven scenarios are best suited for issues occurring at the organizational level
