Carbon containing. 4 out of 6 classes of nutrients are organic: Carbs, fat, protein, and vitamins. Include only those made by living things... does not include compounds such as carbon dioxide diamonds, and a few carbon salts.
Food composed of parts of whole foods. ie butter (from milk)
Foods used frequently or daily. i.e. rice (in Aisa) or Potatoes (in Ireland). If well chosen, these foods are nutritious
The nutrients the body cannot make for itself (or cannot make fast enough) from other raw materiALS; NUTRIENTS THAT MUST BE OBTAINED FROM FOOD TO PREVENT DEFICIENCIES.
aka fortified foods. Foods to which nutrients have been added. If the starting material is a whole, basic food such as milk or whole grain, the result may be highly nutritious. If the starting material is a concentrated form of sugar or fat, the result may be less nutritious.
units of energy. In nutrition science, the unit used to measure the energy in foods is a kilocalorie (kcalori or Calorie): it is the amount of heat energy necessary to raise the temperature of a kilogram (a liter) of water 1 degree Celsius. This book follows the common practice of using the lowercase term calorie (abbreviated cal) to mean the same thing.
Whole or modifies foods that contain bioactive food components believed to provide health benefits, such as reduced disease risks, beyond the benefits that their nutrients confer,. However, all nutritious foods can support health in some ways.
How many classes of nutrients are there
Which nutrients yield energy
Carbs, Fats, and Proteins
What are energy-yielding Nutrients
Nutrients that the body can use the energy they contain. Carbs and fats are important ones but protein does double-duty it can yield energy but it also provides materials that form structures and working parts of body tissues.
Which nutrients are Organic

Recommended Dietary Allowances: nutrient intake goals for individuals; the average daily nutrient intake level that meets the needs of nearly all (97 to 98 percent) healthy people in a particular life stage and gender group. Derived from the Estimated Average Requirements.
Dietary Reference Intakes: a set of four lists of values for measuring the nutrient intakes of healthy people in the United States and Canada. The four lists are Estimated Average Requirements (EAR), Recommended Diatary Allowances (RDA), Adequate Intake (AI),, and Tolerable Upper Intake Levels (UL).
a measure of nutrients provided per calorie of food
Nutrient dense foods in each group
- Meats: chicken, fish, eggs, nuts, and seeds
- Grains: Whole grains, brown rice, enriched
- Veggies: Dark green, Orange, Legumes, starchy
- Fruits: Apples, avocadoes, bananas etc
- Milk:fat-free milk, fat-free milk products
- Oils: liquid vegetables oils, unsaturated
unit of a cell's inheritance; sections of the larger genetic molecule DNA. Each gene directs the making of one or more of the body's proteins.
a cholesterol-containing digestive fluid made by the liver, stored in the gallbladder, and released into the small intestine when needed. It emulsifies fats and oils to ready them for enzymatic digestion.
the body's organs of gas exchange. Blood circulating through the lungs releases its carbon dioxide and pucks up fresh oxygen to carry to the tissues.
a pair of organs that filter wastes from the blood, make urine, and release it to the bladder for excretion from the body.
a large, lobed organ that lies just under the ribs. It filters the blood, removes and processes nutrients, manufactures materials for export to other parts of the body, and destroys toxins or stores them to keep them out of the circulatory system.
an organ with two main functions. One is an endocrine function- the making of hormones such as insulin, which it releases directly into the blood. The other is an exocrine function- the making of digestive enzymes, which it releases through a duct into the small intestine to assist in digestion.
What to do in heartburn
eat smaller meals, drink liquids an hour before or after, but not during meals. wear reasonably loose clothing, and relax after eating.
