Description of Dietary Guidelines for Americans-health
Robert Baird asked:
In response to criticism of the american diet, the US department of Agriculture (USDA) and department of health and human services (DHHS) established the following recommendations that are the basis for the dietary guidelines for Americans
Eat a Variety of Foods
The best way to plan a nutritionally balanced diet is to eat a variety of foods according to the food guide pyramid . This helps to ensure that the recommended dietary allowances (RDAs) of essential nutrients-substances that cannot be made by the body and must be supplied through the diet are provided. Rdas represent sufficient amounts of the more than 50 essential nutrients necessary to meet the needs of nearly all healthy people in the population . The food guide pyramid is helpful for determining how many servings from each food group should be included in your diet.
The foundations of good nutrition are variety and moderation. No one food or food group provides all essential nutrients in adequate amounts. Furthermore, you should consume a variety of foods within each food group. Potatoes are a good example of how foods within a group vary in nutrients and calories: ounces of baked potato yield 98 calories, whereas 3 ounces of potato chips yield 470 calories. Similar examples within food groups include skim milk and ice cream, beans and bologna, olive oil and butter, and whole-wheat bread and doughnuts.
Balance Food Intake With Physical Activity: Maintain or Improve Weight
The achievement and maintenance of a desirable body weight or composition are complex issues and are treated separately in this text. For a complete discussion of principles for maintaining desirable composition by balancing food intake with physical activity.
Choose a Diet Low In Fat, Saturated Fat, and Cholesterol
Perhaps the greatest shortcoming of the american diet is the abundance of fat. The dietary guidelines call for no more than 30% of total daily calories in the form of fat, of which no more than 10% comes from saturated fat. A good percentage ratio is 10: 10: 10 for saturated, monounsaturated, and polyunsaturated fat.
Choose a Diet With Plenty of Grain Products, Vegetables, and Fruits
Starch and fiber belong to the carbohydrate family of nutrients. Carbohydrates are the primary energy source for the brain and nervous system, and they are necessary for burning of fat at rest and during physical activity in other tissues. Dietary guidelines recommend that complex carbohydrates make up at least 45% of the diet. A 2000 calorie diet that meets the DRV of 300 grams achieves the even higher level of 60% of calories from carbohydrates.
Americans seem to be getting a message that carbohydrate intake needs to be increased. Ten year comparisons show that consumption of fresh vegetables, fresh fruit, and canned vegetables are in a long-term upward trend. During the past 20 years, consumption of fresh fruit has increased from 91 pounds per person per year to 120 pounds; fresh vegetables (excluding potatoes) increased from 80 to 103 pounds; and canned vegetables increased from 97 to 111 pounds. Potato consumption has also increased from 68 to 77 pounds; the downside of this trend is that one third of potatoes end up frozen that means high fat french fries.
Carbohydrates supply energy in the form of sugar, or saccharides. The simplest form of carbohydrate is the monosaccharide, which includes glucose and fructose (fruit sugar). Fructose is the sweetest of simple sugars. Disaccharides are double sugars, meaning that they are pairs of monosaccharides chemically linked. Included in this group of sugars are sucrose, or table sugar; lactose, or milk sugar; and maltose, or malt sugar. The last group of sugars is the polysaccharides, which are composed of many single monosaccharides. Polysaccharides are also called complex carbohydrates. They include starch and several forms of fiber.

Ten Tips to Improve Your Fitness Health
Michael Hehn asked:
The following paragraphs summarize the work of health experts who are completely familiar with all the aspects of health. Heed their advice to avoid any health surprises.
Here are ten tips to improve your fitness health. Even athletes who are incredibly fit may not be really healthy. They often tread a fine line between health and illness or injury.
1) Listen to your body. As you are training it is easy to become preoccupied with the repetitions you are doing, or the time you’ve been exercising. Leave your watch at home and slow down or walk when your body hurts.
2) To improve your fitness health you need to eat a varied diet. Five fruit and vegetables a day should be your minimum target. Your health will improve if you eat at least five different kinds of fruit, then any vegetables will be a bonus.
3) Take a complete day off from exercise every once in a while. It doesn’t have to be every week, but doing extra training when you are tired may have a detrimental effect on your health and fitness. You become fitter and healthier through rest as much as exercise.
4) Limit the number of supplements you take. Adequate amounts can in fact be absorbed by modifying the diet without the risks involved by taking a dietary supplement. Consult a professional dietician. Many sprinters and power athletes, for example, take creatine supplements because it gives them a legal edge. There is a risk, though, as it is possible that they have been contaminated by banned substances. This is a risk to your fitness health, and a risk financially if you are a professional athlete.
See how much you can learn about health when you take a little time to read a well-researched article? Don’t miss out on the rest of this great information.
5) Your health will improve if you minimize the number of tablets that you take. Paracetamol may seem okay, but you will be surprised how often a headache can be cured by drinking water, having something to eat or sitting in a quiet room.
6) You will improve your health and fitness by stretching more. Your muscles get shorter through exercise, and if you never stretch you will get injured. One method is to warm up slowly first, then spend several minutes stretching before the main workout. Stretch thoroughly after exercise as well.
7) You need to stay hydrated if you are exercising more. This means drinking water and sports drinks if you are sweating a lot. You lose minerals in your body while sweating. It is recommended to drink five glasses of water a day, but if you are working out you need to drink more than this. Don’t get carried away, though, because it can be just as dangerous to drink too much as too little.
Exercise with other people. You will meet new friends, and your fitness will improve if you have other people to motivate you.
9) Don’t become too competitive as this may harm your health. Motivation from other people is good, but you should only compete against yourself. Try too hard to keep up with someone else, and you could become injured.
10) Have fun! Your health and fitness will improve if you are having fun because you will stick to your exercise program.
