July 30: World AIDS Week

This week was World Aids week, so we talked about the difference between HIV and AIDS, how it effects your immune system, and how one would alter their diet and food handling under these circumstances.

  • HIV = Human Immunodeficiency Virus
  • AIDS = Acquired Immunodeficiency Syndrome

About 70 000 Canadians are currently HIV +. HIV is the virus that causes AIDS. A person can get AIDS after a prolonged period of being infected by HIV and if they do not care for that illness properly. Most common ways of being infected include:

  • Blood transfusion (sharing needles, medical blood transfusion, tattooing etc.)
  • Sexual intercourse
  • Open wounds
  • Born to a HIV + mother

HIV depresses the immune system by hijacking the hosts DNA and it replicates itself, which eventually breaks down the hosts immune (CD4-T cells). A person can live for a long time without feeling any symptoms. However, people are more vulnerable to opportunistic infections. AIDS is the result of uncontrolled symptoms resulting from HIV.

Food and Nutrition: Weight loss is a major issue, so it is recommended 20-30% of an energy (calorie) increase is necessary, mostly from carbs. Some micronutrients may be necessary.

Safe food handling is essential. Avoid raw meat sources such as runny eggs, deli meats, ceviche and carpaccio for example. Some molded cheeses should also be avoided. Because the immune system is depressed overall, all foodsafe principles apply, such as keeping cold foods cold and hot foods hot and avoiding cross contamination.

The good news is, there have been many medical advances and research related to HIV/AIDS and it is becoming more manageable to live with.

July 23: Alcoholic Beverages and Your Health

This segment covered the serving sizes, effect on your body, and benefits and drawbacks of alcohol.

Standard guidelines for consumption has been developed for Canadians to avoid binge drinking:

  • 1-2 a day for women
  • 2-3 a day for men

Standard Serving sizes:

  • 12 oz. is for coolers and beer and is 5% alcohol
  • 4 or 5 oz. is for wines and is 12% (although there are some at 7%)
  • 1.5 oz. is for hard liquor (rum, gin, whiskey) and is 40%

More alcohol is absorbed in your small intestine than in the stomach. It can take about 20 minutes for the alcohol to hit your bloodstream. Having a meal can help reduce the rate at which the alcohol is released in your blood and it is recommended to eat while you drink.

Alcohol is a high energy drink; it is metabolized at 7 kcal/g, which is considered ’empty calories’. Here is a comparison:

  • Fat = 9 kcal/g
  • Alcohol = 7 kcal/g
  • Protein & Carbs = 4 kcal/g

Wine can be beneficial to health, particularly heart disease risk if consumed in moderation. Above one or 2 drinks per day, reduces the protective affect and is not then recommended for health.

The key is to enjoy in moderation throughout the week and avoid binge drinking. Additionally, watch out for those extra calories consumed with mix and snacking!
