Safety Very Imporant?
Diet safety should be in the front of all tests. When evaluating the safety and efficacy of any diet, clinicians should target 3 principle components: the quality of the content of the proposed eating plan.
Microbiological Safety The quantity of food consumed, and the microbiological safety of the foods that are recommended as part of the diet. Foods can be considered safe if they have been prepared using proper sanitary practices, such as pasteurization.
Do Vitamins Really Work?The dietary guidelines issued jointly by the US Department of Health and Human Services (DHHS) and the US Department of Agriculture (USDA) embody the federal government's current recommendations. Most dietitians believe that the more closely the content of an eating plan adheres to these guidelines, the safer it is. A new generation of researchers, however, advocates even stricter dietary vigilance, especially
regarding meat and fat intake.
Food Pyramid Guide 
Diet's should be aimmed for a healthy weight. Be physically active each day. Let the USDA Food Pyramid guide food choices.
Choose a variety of grains daily, particularly whole grains. Choose a variety of fruits and vegetables daily. Keep food safe to eat: Keep hot foods hot and cold foods cold, and store leftovers at the appropriate temperature.
Choosing A Diet Choose a diet that is low in saturated fat and cholesterol and moderate in total fat. Choose beverages and foods that are low in sugar to
ensure moderate sugar intake. Choose foods that are low in sodium and prepare foods using less sodium.
Alcoholic In Moderation Consume alcoholic beverages in moderation, if at all. In general, a nutritionally adequate diet includes a wide variety of foods and allows those who follow it to maintain an appropriate weight. It can readily be adapted to meet the needs of specific physiologic states, such as overweight or old age.Foods from 4 basic groups are essential: whole grains (breads, cereal, rice, and pasta), vegetables, fruits, and lean meat and beans. Adequate vitamin intake is also important.
Avoid Overindulging In Food With No Nutrition Fortified cereals or multivitamin
supplements complete the eating plan. Fatty meats and added fats should be consumed sparingly. Dietary guidelines should be followed as(3 or more servings of fruit and vegetables per day and 6 or more servings of whole grains per day), most people can avoid overindulging in foods with little or no nutritional value.
Review Patient Intake Of Foods It is also important to review patient intake of foods that can increase the risk of cardiovascular disease and obesity. These include energy-dense foods that are high in sugar, saturated fat, and cholesterol.
Weight Maintenance PlanBecause the success rate of permanent weight loss is less than 10%, prevention of obesity is crucial. Physicians can play a pivotal role by emphasizing the importance of diet and exercise in obesity prevention. Most of the diets discussed in this article restrict overall energy intake by restricting the intake of a particular food or food group. Although weight loss will result, the diets are difficult to adhere to for an extended period. In addition, an effective weight-loss or weight-maintenance plan should be followed in conjunction with an exercise regimen.
The Zone Diet Diets that are perceived as quick fixes for weight management problems are always popular. These programs rarely work over the long term, however, and patients should be discouraged from crash-dieting and using other extreme measures to lose weight Clinicians should be aware of which popular diets are based on theories that are scientifically unsubstantiated. The Zone Diet is based on the principle that one can burn excess fat and increase energy by maintaining insulin levels within a certain range--an assumption that has not been proved.
Tenets Of This Diet The 2 fundamental tenets of this diet are that the body must receive an adequate supply of low-fat protein at each meal and that macronutrients (carbohydrates, proteins, and fats) should be consumed in a ratio of 40-30-30, respectively, which the author of the Zone Diet books, Barry Sears, PhD, considers to be the caloric ratio that promotes optimal functioning of the human body. It is believed that consuming macronutrients in this ratio allows for precise glucose control.
Carbohydrates Macronutrients are consumed in uniLts called blocks in a 1:1 ratio at every meal or snack. Each meal consists of 3 blocks of each macronutrient, and each snack consists of 1 block of each macronutrient. One carbohydrate unit consists of 9 g of carbohydrate, one protein block consists of 7 g of protein, and one fat unit consists of 1.5 g of fat. Carbohydrates consumed when following the Zone Diet should have a low glycemic index, so that they raise blood glucose levels slowly producing a moderate insulin response.
Protein-Rich Foods
Diet Examples of carbohydrates that are considered favorable to the Zone Diet are found in vegetables such as broccoli, cauliflower, and tomatoes, and fruits such as oranges, apples, and apricots. Examples of acceptable protein-rich foods include 1 oz 01' skinless chicken breast, 1 oz of tuna, or 2 egg whites.
Consumption Of Omega-6 Fatty Acids A balanced diet should not include The consumption of omega-6 fatty acids is discouraged because the author believes that metabolizing them may be deleterious. In fact, omega-6 fatty acids are polyunsaturated and, in reasonable amounts, are safe to incorporate into a healthy, balanced diet.
