Nutritional Genomics: From 1 Different Sources


the study of the relationships between the human genome, nutrition, and health. There are two main branches of study: nutrigenetics investigates how an individual’s genes affect their response to certain dietary nutrients, whereas nutrigenomics investigates how nutrients ingested can modulate gene expression. In time, nutrigenomics may help to identify the aetiology of certain chronic diseases.

Alfalfa Tea: A Nutritional Tea

Alfalfa tea is known for more than 2000 years and its benefits are shown by recent studies to be good in treating ailments such as kidney stones or arthritis. Alfalfa: the plant and the tea Alfalfa, literally meaning “the father of plants”, is also known as lucerne, holy-hay or trefoil. It has a high nutritional content, and is best known for possessing A, B, C, D, E and K vitamins. This plant has been originally used only as horse feed, but due to its nutritional benefits its usage has been extended to human consumption too. It proved to be a good soil fertilizer, especially a plant growth regulator. As part of the human diet, at first, it was used to promote appetite and stop bleeding, but further studies have revealed many other health benefits. Alfalfa tea is the beverage resulting from brewing the dried herbs. Brewing Alfalfa Tea To make Alfalfa tea:
  • take the dried leaves
  • soak them in boiling water
  • steep them for 10 to 15 minutes (depending on the quantity and flavor preferences)
Consumers described the taste of the resulting Alfalfa tea as refreshing and pleasant to drink. For medicinal purposes, it is advisable to have 5,000 to 10,000 mg of alfalfa leaves steeped three times a day. Another efficient way of intaking Alfalfa is through herbal supplements, like tablets or capsules. Alfalfa Tea benefits Alfalfa tea is successfully used to:
  • lower cholesterol levels
  • help keep calcium in bones and out of artery linings
  • help lower blood sugar levels
  • help in treatment of upset stomach
  • alleviate kidney and bladder woes
  • stimulate the immune system
  • purify the blood
  • carry intestinal waste out of the body
  • reduce cancer risks
Alfalfa Tea side effects Studies have shown that consuming Alfalfa tea, especially in high doses,could have side effects, such as: breaking down red blood cells, aggravating or even causing symptoms similar to systemic lupus erythematosus disease (SLE). The abovementioned tea is not recommended to pregnant or nursing women, and its administration is not advisable to children suffering from diabetes or autoimmune disease. Alfalfa tea is a modern cure for a large array of diseases. It is also largely used as cattle food, due to its nutritional content.... alfalfa tea: a nutritional tea

Nutritional Disorders

Nutritional disorders may be caused by a deficiency or excess of one or more nutrients, or by the presence of a toxin (poisonous element) in the diet.

A diet deficient in carbohydrates is almost inevitably also deficient in protein, leading to the development of protein–calorie malnutrition. Such malnutrition is most often seen as a result of severe poverty and famine (see kwashiorkor; marasmus).

Deficiency of specific nutrients is commonly associated with a disorder of the digestive system, such as coeliac disease, Crohn’s disease, or pernicious anaemia (see anaemia, megaloblastic).

Inadequate intake of protein and calories may also occur in people who excessively restrict their diet to lose weight (see anorexia nervosa), hold mistaken beliefs about diet and health (see food fad), or suffer from a loss of interest in food associated with alcohol dependence or drug dependence.Obesity results from taking in more energy from the diet than is used up by the body. Nutritional disorders may also result from an excessive intake of minerals and vitamins. An excessive intake of saturated fat is thought to be a contributory factor in coronary artery disease and in some forms of cancer.

Naturally occurring toxins can interfere with the digestion, absorption, and/or utilization of nutrients, or can cause specific disorders due to their toxic effects: for example, the ergot fungus found on rye can cause ergotism.... nutritional disorders

Genomics

n. the branch of genetics concerned with the study of genomes. It includes both the mapping of genomes – and ultimately producing a DNA sequence for any particular organism or individual – and understanding how gene expression is controlled and gene products change under different conditions, including disease states.... genomics
