Guide: How to Detect Nutritional Deficiencies
Updated: Jan 4, 2022
Did you know that your physical body can actually tell you what nutrients you may be lacking? This article shares some examples of which physical signs to look for, what those signs mean, why it’s important, and which foods you can incorporate on a day-to-day basis to ensure optimal nutritional levels. You can use this information to check in on your overall health as well as your family’s.
The Nails:
Check for: White spots, vertical or horizontal ridging and/or dipping.
Sign for: Zinc deficiency, Vitamin B6 deficiency, and/or a need for more quality protein in the diet.
Why it’s important:
Zinc is important for immune function, managing inflammation, stomach acid production, reproduction, wound healing, and mood. Does it take a while for your body to heal from cuts/wounds? Zinc is the wound healer.
Vitamin B6 is a big player in metabolism and energy production, it’s needed to utilize neurotransmitters (serotonin/dopamine) which regulate mood and boost the ability to deal with stress.
Protein is the building block of EVERY CELL IN THE BODY. Required for structure, function and regulation of the body’s tissues and organs as well as enzymes, NTs and hormone production.
Boost nutrition with:
Zinc – shellfish like oysters and crab meat, beef, venison, lamb, poultry, pumpkin seeds and chickpeas.
Vitamin B6 – fish (salmon/tuna), poultry, pork, beef, liver, potatoes, avocado, bananas, walnuts, chickpeas and spinach.
Protein – poultry, seafood, beef, organ meats (liver), pork, lamb, venison, eggs, beans and lentils, nuts and seeds.
Bonus note: Another good sign of zinc deficiency is lack of taste and smell.
Check for: Spooned nails or pale colored nail beds.
Sign for: Iron deficiency.
Why it’s important: Iron helps in the production of hemoglobin to bring oxygen throughout the body, prevents anemia, supports energy levels, supports thyroid, protects against anxiety/depression.
Boost nutrition with: Oysters, clams, venison, lamb, poultry, salmon, sardines, beans and lentils, dark chocolate, beef, organ meats – liver, spinach, cashews, tomatoes.
Bonus Note: Plant sources contain non-heme Iron, which has a poorer absorption rate than heme iron of only 2-13%. Heme iron from animal proteins has a 25-40% absorption rate. Vitamin C will support iron absorption (bell peppers, oranges, grapefruit, lemon, kiwi, broccoli, Brussel sprouts, strawberries).
Check for: Weak or thin fingernails that easily bend, crack and chip.
Sign for: Zinc, healthy fats, calcium, biotin and a need for more quality protein.
Why it’s important:
Zinc – important for immune function, managing inflammation, stomach acid production, reproduction, wound healing, and mood.
Healthy Fat – essential for growth, development, and metabolism. Builds hormones, supports healthy skin and tissue integrity, protects organs, and supports nerves and the brain (cognitive function). Fat is a powerful source of energy.
Calcium – strong bones and teeth, required for proper nerve transmission and muscle contraction, can help support healthy blood pressure.
Biotin – energy production, helps regulates blood sugar, mood support and balance, healthy hair/skin/nails.
Protein – the building blocks of every cell in the body. Required for structure, function and regulation of the body’s tissues and organs as well as enzymes, NTs and hormone production.
Boost nutrition with:
Zinc – shellfish like oysters and crab meat, beef, pumpkin seeds and chickpeas.
Healthy fats – coconut oil/yogurt/flakes, extra virgin olive oil and olives, grass-fed butter or ghee, whole eggs, nuts and seeds (flax seed and walnuts), avocado, seafood and caviar.
Calcium – fish (salmon, rainbow trout and sardines), spinach, almonds, white and pinto beans, broccoli, collards, oats, kale, dairy.
Biotin – beef liver, eggs, salmon, avocados, pork, sweet potato, almonds, spinach, broccoli.
Protein – poultry, seafood, beef, organ meats (liver), pork, lamb, venison, eggs, beans and lentils, nuts and seeds.
Bonus note: This can also be a sign of low stomach acid. If this is the case, you may be consuming enough protein in the diet, but are not digesting it properly. When this is the case - some people will also experience symptoms of acid reflux, heartburn, and upper abdominal bloating after eating. If balance is not reached, an overgrowth of opportunistic bacteria and candida can grow throughout the gut.

Digestive Enzymes with betaine hcl (10-30 minutes before meals)
Check for: Cracks on the finger around the nail.
Sign for: Essential fatty acids.
Why it’s important: Fat is essential growth, development and metabolism. Builds hormones, supports healthy skin and tissue integrity, protects organs, and supports nerves and the brain (cognitive function). Fat is a powerful source of energy.
Boost nutrition with: coconut oil/yogurt/flakes, extra virgin olive oil and olives, grass-fed butter or ghee, whole eggs, nuts and seeds (flax seed and walnuts), avocado, seafood and caviar.
The Tongue
Check for: Teeth indentations around the edges of your tongue.
Sign for: Dehydration or zinc deficiency as well possible food allergies/sensitivities you may be unaware of.

Dehydration can cause many symptoms such as muscle cramps, fatigue, headaches and constipation. It’s important to always filter the body with good, clean water to support detox and the body’s natural flow.
Zinc – important for immune function, managing inflammation, stomach acid production, reproduction, wound healing, and mood.
Food allergies/sensitivities can cause an array of symptoms including breathing issues, skin issues, brain function and mood issues, fatigue, digestive issues, joint pain and muscle aches and so much more. Keep in mind that if you are constantly consuming foods that are causing your body and mind distress, you are causing a great deal of inflammation which can cause even more serious issues down the road.

Drink half your body weight in ounces of water daily (150lb = 75 ounces/day).
Zinc - shellfish like oysters and crab meat, beef, pumpkin seeds and chickpeas.
