Build your defenses!

-
This rainy season, boost your immune system by adding these basic nutrients to your daily diet.

In this season, where pouring rains force people to come in closer contact with ailing individuals in enclosed spaces such as malls or public vehicles, and airborne viruses and bacteria are having a heyday floating from one victim to another, the key to good health is a good defense. This will come in a healthy body nourished by these 5 important immunity-building nutrients:
  1. Vitamin C. This readily-available nutrient has been found to increase the production of white blood cells and antibodies, the primary function of which is to fight off infections. Foods rich in this important vitamin include citrus fruits, papayas, guavas, and tomatoes.
  2. Vitamin E. This vitamin has been receiving a lot of attention lately for its antioxidant properties. It stimulates the production of immune cells that produce antibodies which target and destroy bacteria. Vitamin E is present in nuts, seeds, and vegetable oils. A significant amount is available from whole grain cereals, which give you another great reason for enjoying a full serving every morning.
  3. Zinc. This power mineral not only helps increase the production of white blood cells, it even helps them fight harder. Children who have a regular zinc intake have been found to have fewer sick days. While there are zinc supplements that are already available, doctors say that zinc is easily found in fortified cereals, yogurt, beef, and seafood.
  4. Vitamin A. This vitamin is actually a potent combination of beta carotene and retinol. Beta carotene by itself increases the number of infection-fighting cells and their helper T-cells. It also has antioxidant properties, because it helps eliminate free radicals from the body. Vitamin A is also good for the eyes, bones, teeth, skin and hair. It is found in a number of foods such as green leafy vegetables, carrots, milk, mangoes, and eggs.
  5. Omega-3 fatty acids. Essential fatty acids act to protect the body against damages from infections. These are healthy fats from fish such as salmon, sardines, tuna, mackerel, catfish, and shellfish like clams and shrimps.

Cream, Butter, and Ice Cream

-
. In order for a product to be labeled as cream, it must contain 18 percent milk fat or more. Light whipping cream must contain at least 30 percent fat, and 36 percent fat is the minimum fat content for heavy whipping cream. Half-and-half, an equal mixture of both milk and cream, must have at least 10.5 percent fat. The various grades of cream are valued for their smooth, thick texture. They are often used in cooking instead of milk, because they are less likely to form a skin when heated and can be whipped into a stiff foam. When chilled cream is churned gently, the fat globules gather together to form butter, leaving buttermilk as the by-product. Butter contains at least 82.5 percent fat. In the past, before the advent of widespread refrigeration, salt was added to butter to retard bacterial spoilage; now salt is added mainly for flavor. Ice cream, a popular frozen dessert, is made of milk, cream, sugar, and flavoring. The mixture is slowly beaten while chilled until it is partially

How HIV Causes Infections

-
HIV transmission occurs when a person is exposed to body fluids infected with the virus, such as blood, semen, vaginal secretions, and breast milk. The primary modes of HIV transmission are (1) sexual relations with an infected person (see Sexually Transmitted Infections ); (2) sharing hypodermic needles or accidental pricking by a needle contaminated with infected blood; and (3) transfer of the virus from an infected mother to her baby during pregnancy, childbirth, or through breast-feeding. When HIV enters the body, it infects lymphocytes, which are a type of white blood cell in the immune system . HIV uses its glycoproteins to attach itself to receptors on the surface of a lymphocyte. The outer envelope of HIV then fuses with the lymphocyte, enabling the HIV capsid to enter the lymphocyte itself. HIV commandeers the genetic material of the lymphocyte, instructing the cell to replicate more viruses. The newly formed viruses break free from the host, destroying the cell in the process

Deoxyribonucleic Acid

-
Deoxyribonucleic Acid (DNA), genetic material of all cellular organisms and most viruses. DNA carries the information needed to direct protein synthesis and replication. Protein synthesis is the production of the proteins needed by the cell or virus for its activities and development. Replication is the process by which DNA copies itself for each descendant cell or virus, passing on the information needed for protein synthesis. In most cellular organisms, DNA is organized on chromosomes located in the nucleus of the cell .
