During the fall & winter seasons, people become more aware of taking care of their immune system, and there is a nutrient that you should focus on, and it isn’t Vitamin C.

Ps. you should be treating your immune system right all year long, so here is a previous post on How to Boost Your Immune System All Year Round.

Zinc

Zinc is an essential trace mineral that is vital for human health. It is a component of more than 300 enzymes and hormones and plays a crucial part in the health of our skin, teeth, bones, hair, nails, muscles, nerves, and brain function. Zinc controls the enzymes that operate and renew the cells in our bodies and regulates the sensory organs for sight, smell, and taste. While this essential micronutrient is significant throughout life, it is especially important for times of rapid growth, such as childhood, adolescence, and pregnancy, due to its role in helping cells grow and multiply.

So, let’s talk in more detail about the daily requirement for zinc, how to find it in its most absorbable form, why a deficiency may occur, and different signs and symptoms you may experience if a deficiency exists.

According to the National Institute of Health, the daily requirement of zinc will vary depending on your age. On average, babies will require approximately 2 mg/day, children 3-5 mg/day, teenagers and adults 9-11 mg/day, and pregnant or breastfeeding mothers 11-13 mg/day. As always, it’s best to consult with your healthcare provider to determine your precise bio-individual need.

Where Do I Get Zinc From?

In terms of where to find it, zinc is present and readily absorbable from many types of food.

• Oysters! A typical oyster weighing approximately one ounce will contain about 8-9 milligrams of zinc, which is close to the daily requirement for an adult!

• Organs and meat of pasture-raised beef, chicken, and lamb, as well as wild-caught fish and crustaceans, like crab and lobster.

• Nuts & seeds

• Shiitake and Crimini mushrooms

• Spinach

• Asparagus

• Quinoa and oats

• Raspberries & other berries

However, some of these plant-based sources of zinc come with a caveat.

Many of these plant-based sources have a substance within them, commonly referred to as an anti-nutrient, called phytic acid. While these phytate-rich foods are typically healthy, in terms of zinc absorption, they pose a problem. The phytic acid in seeds, grains, legumes, and nuts actually binds to minerals like zinc, iron, and calcium which greatly inhibits their absorption.

One way to reduce phytic acid content is to soak and sprout your seeds, grains, legumes, and nuts before consumption. Another way to increase zinc absorption is to ensure the consumption of animal proteins with any phytate-rich food as they improve zinc absorption. So, eating your meat with your greens has more weight to it than just a balanced meal!

How Do I Know If I’m Deficient? 

Unfortunately, zinc deficiencies are far too common among populations whose main food sources come from grains, cereals, and processed foods.

Due to the many roles zinc plays in the human body, there is a broad range of physiological signs of a potential deficiency.

Organ systems known to be affected by such a deficiency include the skin, gastrointestinal, central nervous, immune, skeletal, and reproductive systems.

Signs of a zinc deficiency can vary depending on the severity of the condition but may include things like

• loss of hair

• frequent infections

• poor appetite

• lack of taste or smell

• skin sores

• slow growth rate

• trouble seeing in the dark

• or wounds that take a long time to heal

There are two other important things worth noting about zinc.

1. For women on birth control, a side effect of the pill is inhibited zinc absorption. For this population, it’s especially important to incorporate zinc-rich foods.

2. On the flip side, too much zinc, whether from diet or supplementation, can impair copper status. Here, the recommendation is to focus on food sources that are rich in both zinc and copper.

Zinc is critical to every aspect of our biology and must be incorporated into our diet on a daily basis. As always, be sure to focus on high-quality, nutrient-dense whole foods that include a variety of macro and micronutrients to ensure adequate balance and absorption! 

So, which juices would have good amounts of Zinc in them?

1. The Guardian

2. Brain Booster

3. The Shrinker
