When Our Kids Aren’t Getting Enough

Being a parent is a truly rewarding experience. But, if you’ve had children, you’ll likely know some of the main stress inducers that come with the job. Along with “Will they ever sleep through the night?” and “When will they ever stop wetting the bed?” one of the big ones involves how and what our children eat (or don’t eat!).

Because it can be such a concern for many parents, we explore how nutrient deficiencies can affect our kids, how to spot them, and—most importantly—how to prevent them. Some of the nutrients our children may not be getting enough of include vitamins B, C, and D; minerals calcium, magnesium, potassium, iron, and zinc; and fiber.

B vitamins

Eight of our body’s 13 essential vitamins begin with the letter B. Each of the eight Bs is a chemically distinct vitamin that has an inherently important role in our kids’ overall health—and together they’re essential to many aspects of their well-being.

Why they’re important

Collectively, B vitamins are essential to many aspects of brain function, energy production, and our body’s ability to build and repair muscle mass. Deficiencies in B vitamins are most often seen in vitamin B12 (especially for vegan and vegetarian kids) and B9 (folate).

Signs of deficiency

• fatigue
• weakness
• anemia
• loss of appetite, weight loss
• failure to thrive and grow
• difficulty with memory and concentration

 

 

Vitamin C

Although we often think about vitamin C when we have a cold, our children’s bodies depend on this important nutrient every day for a host of important functions.

Why it’s important

With critical roles in our immune system, wound healing, bone health, and antioxidant protection, it’s especially important for our kids to get enough in their diets. Luckily, there are plenty of vitamin C-rich foods that’ll help keep intake up and their diet fun.

Signs of deficiency

• irritability
• poor appetite
• bleeding gums
• easy bruising
• dry skin
• slow wound healing

 

Vitamin D

This important nutrient can be naturally found in a few foods—egg yolks and fatty fish, is added to fortified dairy products such as milk, and can be consumed via supplements. However, the body also makes the vitamin when exposed to sunlight.

Why it’s important

Also known as the sunshine vitamin, this fat-soluble essential vitamin aids in the regulation of calcium and phosphorous in our bodies. Because of this, vitamin D plays a very important role in building and maintaining our bones and teeth.

Signs of deficiency

• bone pain
• muscle aches
• fatigue
• mood changes
• dental problems

 

 

Calcium

One of the most abundant minerals in our bodies, calcium supports the structure of our (and our kids’) bones and teeth, and it’s also important for muscle and nerve function and hormone release.

Why it’s important

Bone calcium stops increasing in young adulthood, so getting off to a healthy start is critical to strong bones later in life.

Signs of deficiency

• muscle cramps or weakness
• numbness or tingling in fingers, lips, feet
• poor appetite
• confusion, forgetfulness

 

 

Magnesium

The mineral magnesium plays many roles in the body, including blood sugar regulation, muscle and nerve function, blood pressure regulation, and the regulation of various proteins and hormones.

Why it’s important

Magnesium is also crucial for activating vitamin D, which has long been recognized as essential for a healthy immune system. Some older children can be more at risk of deficiency of this important mineral.

Signs of deficiency

• loss of appetite
• nausea/vomiting
• fatigue
• weakness

 

 

 

Potassium

An essential nutrient, potassium is found in all of our body tissues. It plays important roles in maintaining total body fluid volume, acid and electrolyte balance, and normal cell function.

Why it’s important

The fact that kids consume far more sodium than is healthy for their long-term health is concerning, since the combination of too much sodium and too little potassium in our diet is associated with higher blood pressure.

 

 

Signs of deficiency

• muscle weakness
• cramps
• constipation
• fatigue
• confusion

 

 

Iron

Iron is an essential nutrient best known for its role as a component of hemoglobin, the oxygen-carrying protein in the blood that helps move oxygen from the lungs to the rest of the body. It also helps muscles store and use oxygen.

Why it’s important

Children need a steady intake of iron to fuel their rapid growth and development. It’s especially important for teenage girls to replenish the iron that their bodies lose during menstruation.

Signs of deficiency

• weakness, fatigue
• shortness of breath
• dizziness, headache
• irritability
• feeling cold
• pale skin

 

 

 

Zinc

An essential nutrient, zinc is almost as plentiful in the body as iron. It’s found in our eyes, brains, pancreas, kidneys, liver, and adrenal glands.

Why it’s important

Zinc is important for growing kids’ brain development, sensory processing, memory, and cognition. It’s also an important element in immune function.

 

Signs of deficiency

• loss of appetite
• hair loss
• diarrhea
• weight loss
• delayed wound healing

 

 

Fiber

There are two types of fiber we need for good health. Soluble fiber (in mostly fruits and veggies) absorbs water as it passes through our digestive tract and makes us feel fuller. Insoluble fiber (in cereals and whole grains) passes through our digestive tract without much change and improves the quality of bowel movements.

Why it’s important

Fiber promotes good digestive health, regular bowel movements, and blood sugar balance in both children and adults, but intake for Americans, including kids, is woefully inadequate.

Signs of deficiency

• constipation
• diarrhea
• belly pain
• weight gain
• fatigue
