Posted by ACalorieCounter October 11th The key to controlling your weight and improving your health is quite simply eating right. Read your food labels and check over the nutrition facts to ensure that you are eating lots of the good stuff, and little or none of the bad stuff. That's pretty easy to understand. However, what might be slightly tougher for some people to understand are the food labels themselves.
Know all Definitions throughout the chapter Table Standards of Practice and Scope of Practice: Personal Trainers versus licensed Dieticians Should be familiar with concepts of nutrition. Professional, legally qualified to practice in the field of nutrition is Registered Dietician RD.
RD is specialized in food and nutrition expert with extensive training. Practice of nutrition is governed by national credentialing programs and state licensing laws.
Daily Energy Needs Calorie — amount of heat energy required to raise temp of 1 gram of water 1C. Calorie — Unit expression of energy equal to 1, calories. Amount of heat energy required to raise 1 KG or liter of water 1C or kilocalorie.
Kilocalorie — equal to 1, calories, raise 1kg of water 1 degree C. Estimated total energy expenditure TEE is defined as amount of energy calories spent, on average, in a typical day. TEE the sum of three different energy components: Affected by wide variety of factors including age, sex, genetics, hormonal changes, body size, body comp.
Protein Protein — Amino acids linked by peptide bonds. Build and repair body tissues and structures. Involved in synthesis of hormones, enzymes, and other regulatory peptides.
Structure of Protein Made up of amino acids linked together by peptide bonds. Body uses approx 20 amino acids to build its many different proteins.
Two general classes of amino acids: Essential amino acids cannot be manufactured in the body — therefore must be obtained from food supply or some other exogenous source. Nonessential — body can manufacture them from dietary nitrogen and fragments of carbs and fat.
Arginine and histidine are semiessential amino acids. Digestion, Absorption, and Utilization Proteins must be broken down into constitutent amino acids before body can use them or repair tissue or as energy substrate.
Proteins encounter HCL in stomach which uncoils denatures protein so that digestive enzymes can begin dismantling peptide bonds. The enzyme pepsin begins to cleave protein strand into smaller polypeptides strands of several amino acids and single amino acids.
As protein fragments leave stomach and enter small intestine, pancreatic and intestinal proteases protein enzymes continue to dismantle the protein fragments. Resulting dipeptides, tripeptides, and single amino acids are then absorbed through the intestinal wall into enterocytes and released into the blood supply to the liver.
Once in bloodstream, free-form amino acids have several possible fates: Amino acids are first deaminated stripped of amine groupallowing remaining carbon skeleton to be used for production of glucose or ketones to be used for energy.
Removed amine group produces ammonia, which is converted to urea in the liver and excreted as urine by the kidneys. If intake exceeds need for synthesis, then proteins are deaminated, carbon fragments stored as fat.
Protein in Foods If food supplies all essential amino acids in appropriate ratios it is called complete protein.Fats, known chemically as the molecules triesters of glycerol (triglycerides) and fatty acids, are one of the three macronutrients (fats, carbohydrates, proteins).
Fat is vital for body processes such as digestion, transport, conversion, and energy extraction. We would like to show you a description here but the site won’t allow us. Caloric Balance. The caloric balance of your diet is one factor in determining your overall health. You are in caloric balance when, over time, the number of calories you take in matches the number of calories you burn through metabolism and physical activity.

Obesity is a medical condition in which excess body fat has accumulated to the extent that it may have an adverse effect on health. It is defined by body mass index (BMI) and further evaluated in terms of fat distribution via the waist–hip ratio and total cardiovascular risk factors.
BMI is closely related to both percentage body fat and total body fat. Fat also fills your fat cells and insulates your body to help keep you warm. The fats your body gets from your food give your body essential fatty acids called linoleic and linolenic acid. They are called "essential" because your body cannot make them itself, or work without them.
