- Lesson of The digestive system
Every being needs to absorb some energy in order to develop itself. The alimentary adaptation to satisfy physiological needs is called dietetic. It makes intervene some nutriments from different natures in variable quantities. Some are fresh and need to be conserved in the fridge at +4°C.
Food Guide Recommendations[edit | edit source]
- The energy contribution of main nutrients is :
- Below is the percent of each macronutrient that your diet should consist of each day :
- Because the sensation of satiety from the stomach to the brain takes 15 to 20 minutes, eating more slowly can help prevent overeating. Also, one should drink 8 oz of water a day, where more than 25 % comes from the food that you ingest, which should be preferably cooked properly and thoroughly chewed in order to facilitate digestion and avoid food poisoning.
- Between 2 to 6g of salt per day.

The nutritional content children are getting is a serious problem in the United States as well as many other developed countries. Improving children’s nutrition will help decrease the leading causes of death and improve the most important determinants of health. Many such problems with nutrition include the following: Research suggests that not having breakfast can affect a child’s intellectual performance. Nearly 80% of students do not eat fruits and vegetables 5 or more times per day. Also, the prevalence of overweight among children aged 6 to 11 more than doubled in the past 20 years, going from 7% in 1980 to 18% in 2004. 61% of overweight young people have at least one additional risk factor for heart disease, such as high cholesterol or high blood pressure. Children who are overweight are also at greater risk for the following problems: bone and joint problems, sleep apnea, social and psychological problems, poor self-esteem, more likely to become overweight or obese adult, type 2 diabetes, stroke, several types of cancer, and osteoarthritis. These are some shocking results that are affecting children everyday. Healthy lifestyle habits, including healthy eating and physical activity, can lower the risk of becoming overweight and developing these related diseases.
One way to make sure your child is getting the nutrition he/she needs is to make sure they "eat the rainbow":
- Red- Bell peppers, Cherries, Watermelon, Strawberries, Beets, Radishes
- Orange- Apricots, Cantaloupe, Mango, Carrots, Peaches, Sweet potatoes
- Yellow- Bananas, Pineapple, Squash, Star fruit, Yellow onion
- Green- Asparagus, Broccoli, Honeydew melon, Spinach, Kiwi, Peas
- Blue/Purple- Blackberries, Eggplant, Figs, Plums, Raisins, Grapes
The darker the fruit or vegetable the healthier it is (for example, it is healthier to choose deep green spinach over light green lettuce).
