20 Immune-Boosting Foods for Preemptive Health in Toronto Amid Monkeypox Concerns

Strengthen Your Immune System with These Nutrient-Rich Foods before we see Monkeypox in Toronto.

Updated Aug 25, 2024

As global attention turns toward emerging health threats, monkeypox has moved to the forefront of many conversations. Monkeypox Virus also known as mpox is an infectious disease spread through contact. There are 2 strains of mpox, clade 1 and clade 2, with the former being the more severe strain with a 3.6% fatality rate and is currently spreading throughout Central and East Africa, with a huge impact in Congo. At the same time, the latter is much less severe with a 0.2% fatality rate.

Since the new year, 162 cases have been reported so far of Clade 2 by the Government of Canada. Although the new strain hasn't yet reached Canada, we need to take a look at how we can raise our immunity and health to take preventative measures by eating well. So today, we're taking a look at 20 immune-boosting foods that you can find right now-in season-in Toronto.

What are Immune-Boosting Foods?

Much like our usual diets, different macronutrients and micronutrients play various roles in our body's immunity function. Obtaining the required amounts of nutrition for our health is extremely important. Most foods considered to be immune-boosting contain micronutrients you often don't find in many other foods, which include mainly: vitamins, minerals, and antioxidants.

Some of these nutrients include:

  • Vitamin A: Reduces inflammation
  • Vitamin C: Likely the most well-known micronutrient that bolsters the immune system by stimulating the production of white immune blood cells.
  • Vitamin D: Moderates the regulatory immune function and inhibits inflammatory responses.
  • Vitamin E: Acts as an antioxidant, protecting cells from damage.
  • Zinc: Essential in cell development and communication
  • Argine, Cysteine, Glutamine, Glutamate, Taurine: Amino acids present in proteins that can be found in animal proteins that are necessary for maintaining health.
  • Flavonoids: Contain antioxidant properties to enhance immune response
  • Curcumin: Excellent detoxification properties to cleanse the system.
  • Probiotics and Prebiotics: Foods with healthy bacteria supporting gut health and in turn the nutrition you gain from the foods you eat and digest

While these highly beneficial nutrients are in these foods, it's often difficult to absorb them without necessary macromolecules like lipids, which is why it is important to maintain your intake of other nutrients while eating immune-boosting foods to stay healthy.
