Fat has always been looked at as bad, but it is only bad if one doesn’t understand the different types of fat and how they work or the importance of keeping your fat intake at a moderate level. Fat contains a certain amount of calories, which we need. But an excessive amount of fat or calorie intake can lead to weight gain or obesity. Fats are categorized as the “bad fats” which include saturated and trans-fats. Then there are the “better fats”, which are unsaturated fats, monounsaturated fats and polyunsaturated fats fall under the unsaturated category. The “bad fats” are not good for the body but are found in most foods like meat and dairy products. A large amount of these fats could result in high cholesterol levels. Saturated fats have a chemical makeup in which the carbon atoms are saturated with hydrogen atoms. Saturated fats are typically solid at room temperature. Unsaturated fats most of the fat that you eat should come from unsaturated sources: polyunsaturated fats and monounsaturated fats. In general, nuts, vegetable oils, and fish are sources of unsaturated fats(http://www.cdc.gov). Trans fatty acids is also found in many foods, trans fatty acids cam be very harmful to the body increasing cardiovascular health problems. Fiber is another substance that is needed to help the body maintain a certain balance and that helps promote a healthy lifestyle . Fiber initially helps with digestion and regulation of the digestive system and it also helps with lowering cholesterol. There are two types of fiber, soluble(dissolves in water) and insoluble(doesn’t dissolve in water) fiber, both are good for the body in their own way. Soluble fiber helps with lowering…
Nutrition has a lot of components under it, like carbohydrates, fiber, protein, fats and more.
But let’s start with carbohydrates; well there are simple and complex carbohydrates. A carbohydrate is an organic compound with the empirical formula Cm(H2O)n (where m could be different from n); that is, consists only of carbon, hydrogen, and oxygen, with a hydrogen: oxygen atom ratio of 2:1 (as in water). Simple carbohydrates are also called simple sugars and…
chicken and beans. All of the foods mentioned before provided lipids. The recorded protein, carbohydrates and lipid intakes were above the recommendations of my DRI. Since they were too high I would recommend eliminating the beef and any parts of the chicken and turkey which have excess fat. I would add more lean meats and organically proteins. Surely I would eliminate any high fat foods, emphasize in low fat like vegetables and salads. I ate both complete and incomplete proteins, but combining both…

Carbohydrates are the main energy source for the human body. The primary function of carbohydrates is to provide energy for the body, especially the brain and the nervous system. An enzyme called amylase helps break down carbohydrates into glucose(blood sugar), which is used for energy by the body.
When carbohydrates are in our body, they are being broken down and used as energy. When the body does not need to use the carbohydrates for the energy, it stores them into the…
secretions such as bile salts, enzymes and bicarbonate. The bile salts created by the liver help digest fats and fat-soluble vitamins. The pancreatic enzymes help digest carbohydrates and fats. The chyme is then passed down to the middle of the small intestine, the jejunum. Mainly in the first half of the jejunum, the majority (about 90%) of nutrient absorption occurs involving proteins, carbohydrates, vitamins, and minerals (Your Digestive System, n.d.). From the jejunum, the remaining chyme enters…
Food labels give an indication to serving size, calories, and nutrition information. They will also include daily value information and a quick guide to daily percentage value. Making better food choices becomes easier when practicing a method known as the 5/20 rule. The 5/20 states that 5% or less of any nutrient is a low amount and 20% or more of any nutrient is a high amount. Nutrients such as fat, cholesterol, sodium, and carbohydrates are things that you want to limit. To get less out of these…

Health Study Guide Chapter 5:
1.) NUTRITION: the process by which the body takes in and uses food
-Certain foods produce different benefits or bad health effects.
-Good nutrition enhances quality of life and prevents disease.
2.) CALORIES/KILOCALORIES: units of heat that measure the energy used by the body and the energy that foods supply to the body
3.) NUTRIENTS: substances in your body that your body needs to grow, to repair itself and to supply you with energy.
This translates to a healthy weight range of 125 to 168 lbs.However, BMI does not take body composition into account. A weight above this range could still be considered healthy if your percentage body fat is less than average. For more accurate determination of body fat levels, consider using a body fat caliper.
