HIV / AIDS:
Human Immunodeficiency Virus /
Acquired Immune Deficiency Syndrome
AIDS is a disease of the human immune system which is caused by the Human
Immunodeficiency Virus.

Nutrition and HIV/AIDS:
• Wellness & nutrition is very important to improve the patients’ immune system.
• Proper nutrition can reduce the side effects of HIV medication (anti-retro virals.)
• Reduce the loss of energy.
• Adequate nutrition in the form of vitamins, minerals, proteins, carbohydrates and
fats must be consumed daily.
• This plays a role in delaying the onset of AIDS and therefore improves the lifespan of
a sufferer.

o Lipid abnormalities (fat – energy)
- Immune suppression
o Food safety and proper hygiene
Nutrition:

daily:
Macro Nutrients – Proteins, carbohydrates & fats
Without proteins and fats, a sufferer will lose considerable body weight, making them more
