Zinc is a mineral and an essential micronutrient that’s vital to your health. Micronutrients is a term used to describe vitamins and minerals. They’re critical for several important functions in your body and must be consumed from food. Humans must obtain micronutrients from food (ie: an external source) since your body cannot produce vitamins and minerals — for the most part. That’s why they’re also referred to as essential nutrients. Vitamins are organic compounds made by plants and animals which can be broken down by heat, acid or air. On the other hand, minerals are inorganic, exist in soil or water and cannot be broken down. When you eat, you consume the vitamins that plants and animals created or the minerals they absorbed. [3]

Of note, Macronutrients, on the other hand, include proteins, fats and carbohydrates.Your body needs smaller amounts of micronutrients relative to macronutrients. That’s why they’re labeled “micro.” [3]

The micronutrient content of each food is different, so it’s best to eat a variety of foods to get enough vitamins and minerals. An adequate intake of all micronutrients is necessary for optimal health, as each vitamin and mineral has a specific role in your body.

Vitamins and minerals are vital for growth, immune function, brain development and many other important functions. [3]

Zinc is found in cells throughout your body. According to the National Institutes of Health (NIH), zinc is crucial to many aspects of your health. Here are a few examples of what zinc does:

  • helps your immune system defend against viruses and bacteria
  • supports your body’s protein production
  • helps your body make DNA (the genetic material in all cells)
  • supports your senses of smell and taste
  • helps wounds heal [2]

Zinc is found in (but not limited to): 

  • Meat
  • Shellfish
  • Oysters
  • crab
  • Legumes (eg: chickpeas, lentils and beans)
  •  seeds (particularly with significant amounts of zinc: hemp, pumpkin, squash and sesame seeds)
  • Nuts (eg: pine nuts, peanuts, cashews and almonds)
  • Dairy foods (eg: cheese and milk)
  • Eggs
  • Whole grains (eg: quinoa, oats, wheat, rice)
  • Dark chocolate (ie: high calorie & sugar contents, hence not to be a primary source!)
  • Most vegetables are poor sources of zinc, but some contain moderate amounts and can contribute to your daily needs, especially if you don't eat meat (eg: kale, green beans as well as potatoes both regular and sweet) [1].

Your body doesn’t store zinc, so you need to eat enough every day to ensure you’re meeting your daily requirements. [1]

Insufficient zinc in your diet can have the following effects:

  • slow growth for infants and children
  • delayed sexual developments in adolescents
  • impotence in men
  • hair loss
  • diarrhea
  • skin and eye sores
  • weight loss
  • problems with wound healing
  • lowered ability to taste and smell food
  • decreased alertness levels

Who’s at risk for a zinc deficiency?

Those who are at risk of getting an inadequate amount of zinc include:

  • vegetarians
  • people with certain diseases, such as chronic renal disease, chronic liver disease, diabetes, or sickle cell disease
  • people with certain gastrointestinal diseases, such as Crohn’s disease or ulcerative colitis
  • people who misuse alcohol
  • pregnant and lactating women
  • older infants who are exclusively breastfed
  • people who take too much copper (because zinc and copper compete for absorption)
