Nutrients Missing from Low-Carb Diets?

💥 🗞️ New Study!!

When compared with diets not restricting carbohydrates, low-carb diets may lead to nutrient depletions—especially of some B vitamins and magnesium.

This recent study found that some of the nutrient requirements not being met by low-carb diets included thiamine (vitamin B1), iron, calcium, magnesium, and selenium.

Red blood cell levels of thiamine were lower and low levels of magnesium were more common in people following a low-carb diet.

This is not medical advice.

This is just something to be aware of if you have chosen to follow a low-carb diet.

It is always best to make dietary changes under the guidance of a practitioner who understands nutrition, metabolism, and supplementation.

40% of Female Teens Deficient in This Nutrient

💃 If you’re a nonpregnant woman or teen, listen up.

A study just published in JAMA found 40% of US females between the ages of 12 and 21 were deficient in iron 🩸

Why should you care?

Because screening for iron deficiency is not routine for this age group!

Guidelines in the US recommend screening for iron-deficient anemia every 5-10 years, but this recent study found that only 6% of the participants actually had anemia, compared with the 40% with iron deficiency.

⚠️ That means iron deficiency can exist WITHOUT anemia and can easily be missed by routine screenings.

What can we do?

The best way to test for iron deficiency is with a blood test for ferritin 🩸It’s a simple thing, but your provider needs to be proactive to order it and know how to interpret it.

In functional medicine, we aim for optimal levels on blood tests, which are not always the same as what’s considered “normal.” If ferritin levels are low, this can usually be corrected through dietary changes and supplementation.
