Fiber promotes the wavelike contractions that keep food moving through the intestine. Also, high-fiber foods expand the inside walls of the colon. This eases the passage of waste. Fibrous substances pass through the intestine undigested. They also absorb many times their weight in water, resulting in softer, bulkier stools. Insoluble fiber is found in wheat, rye, bran, and other grains. It is also the fiber found in most vegetables. See 
Scurvy is a disease that results from insufficient intake of vitamin C and leads to the formation of livid spots on the skin, spongy gums, and bleeding from almost all mucous membranes. The spots are most abundant on the thighs and legs, and a person with the ailment looks pale, feels depressed, and is partially immobilized. Scurvy was at one time common among sailors whose ships were out to sea longer than perishable fruits and vegetables could be stored and by soldiers who were similarly separated from these foods for extended periods.
Beriberi is a nervous system ailment caused by a deficiency of vitamin B1 (thiamine), the symptoms of which may include weight loss, emotional disturbances, impaired sensory perception, weakness and pain in the limbs, and periods of irregular heartbeat. Swelling of bodily tissues is common. In advanced cases, the disease may cause heart failure and death. The origin of the word is from the Sinhalese (Sri Lankan) language meaning "I cannot, I cannot".
Beriberi occurs in people whose staple diet consists mainly of polished white rice, which contains little or no thiamine. Therefore the disease has been seen traditionally in people in Asian countries (especially in the nineteenth century and before) and in chronic alcoholics with impaired liver function. If a baby is fed the milk of a mother who suffers from a deficiency in thiamine, the child may develop beriberi.
Rickets is a disorder which most commonly relates directly to Vitamin D deficiency, which causes a lack of calcium being absorbed. It can also arise, however, from other causes such as certain types of rare tumors or any phosphate-wasting disease. Because calcium is an essential nutrient which aids bone rigidity, the lack of it being absorbed into the body causes fragile or malformed bones, which are unable to support the weight of a growing body. Rickets causes bone pain, slowed growth in children, dental problems, muscle loss and increased risk of fractures (easily broken bones).
Pellagra is a vitamin deficiency disease caused by dietary lack of niacin and protein, especially the essential amino acid tryptophan. Symptoms of pellagra are red skin lesions, diarrhea, dermatitis, weakness, mental confusion, and eventually dementia. This disease can be common for persons who obtain most of their food energy from corn, as corn is a poor source of tryptophan. Therefore this disease can be common amongst people who live in rural South America where — during winter — they live on corn. Usually the symptoms show during spring, and disappear over summer, to return the next spring, after another long winter.
Early, noticeable symptoms of Overt B12 Deficiency: Unusual fatigue, faulty digestion, no appetite, nausea, loss of menstruation. Also numbness and tingling of the hands and feet, nervousness, diarrhea, mild depression,etc. See 
Because Vitamin B12 cannot be obtained through plant sources, total vegetarians (vegans) are advised to eat foods with B12 added (such as fortified soy milk, fortified margarines, or many commercial breakfast cereals), certain brands of nutritional yeast, or take dietary supplements (a good multivitamin will likely include B12 in sufficient quantities).
Saturated fats and trans fatty acids are the kinds of fats most likely to cause heart disease. Saturated fats are found mainly in animal products (eggs, butter, cheese, whole milk, and whole milk products), and in coconut, palm, and palm kernel oil. Trans fatty acids appear in foods containing hydrogenated fats like margarine and crackers. To reduce the risk of heart disease, replace saturated fats with unsaturated fats like canola oil, olive oil, flax seed oil, nuts, avocado, soy products, and nut butters. Choose margarine, cookies, crackers, and snack foods that do not contain hydrogenated fats (read the label). See 
There are a several reasons why sugar is ruining your health: Sugar can suppress the immune system; Sugar leads to cancer of the ovaries; Sugar can cause heart disease; Sugar can cause appendicitis; Sugar can cause multiple sclerosis; Sugar can increase cholesterol; Sugar can increase the systolic blood pressure; Sugar can cause drowsiness and decreased activity in children; Sugar can contribute to Alzheimer’s disease; Sugar can lead to prostrate cancer; Sugar can cause liver tumors; etc. 
Several ways to use less sugar: Cut down slowly; go half and half; establish rules about dessert; If you must eat sweets, eat them with meals; Choose the right breakfast cereal; Don't skip meals; Don't add sugar to foods; ot for a walk when you crave sweetness; Go fat-free if you must have sweets. 
- Definition of Essential Amino acids
- the nine a-amino acids required for protein synthesis that cannot be synthesized by humans and must be obtained in the diet: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Of the 28 amino acids needed by humans, 9 of them cannot be manufactured by the body and are thus termed "essential."
Only some foods contain all the essential amino acids. These are: milk and dairy products, eggs, fish, meat and poultry. If you don't eat animal products, the only way you can get all the essential amino acids is by combining plant foods. For example: corn plus peas or beans, rice plus beans, lentils plus bread.

Another term that comes up when we talk about protein nutrition is the term essential amino acid. Our bodies can make quite a number of amino acids from other chemicals that are contained in the body and can convert some amino acids into other amino acids. However, there are some amino acids we are not able to synthesize ourselves. Those particular amino acids and they must be provided to us in our diet. Those amino acids are referred to as the essential amino acids. It's not to say that the non-essential amino acids are not necessary, it's just that it is not necessary for them to be in our diet because other things in the diet can be used to make them. 
The fat soluble vitamins are soluble in lipids (fats). These vitamins are usually absorbed in fat globules (called chylomicrons) that travel through the lymphatic system of the small intestines and into the general blood circulation within the body. These fat soluble vitamins, especially vitamins A and E, are then stored in body tissues. Two common vitamins that are fat soluble (A, D, E, and K). Two vitamins that are water soluble (B and C). It determines how each vitamin acts within the body.
