Over Half the World's Population Is Missing Key Nutrients—Are You?

A groundbreaking study from Harvard T.H. Chan School of Public Health, UC Santa Barbara, and the Global Alliance for Improved Nutrition reveals that more than half of the global population isn't getting enough essential micronutrients like calcium, iron, and vitamins C and E. Published in The Lancet Global Health, this research estimated deficiencies in 15 crucial nutrients across 185 countries.

The takeaway? Many of us are falling short on vital nutrients—nutrients that play a major role in everything from preventing pregnancy complications to strengthening our immune systems. The numbers are striking:

·      68% of people globally aren't consuming enough iodine.  Found in a variety of foods including seaweed, navy beans and potato.   

·      67% lack sufficient vitamin E

·      66% fall short on calcium.  Greens like collard and broccoli are good sources especially when enhanced with sources of inulin (think bananas and onions) which boosts absorption.

·      65% don’t get enough iron found in plant sources like beans, lentils, raisins, chickpeas and leafy greens.

·      55% don’t get enough vitamin C.   

Women are more likely to be deficient in iodine, iron, and vitamin B12, while men are lagging on nutrients like calcium, magnesium, vitamin A, and vitamin C. Young people aged 10–30, particularly in regions like South Asia, sub-Saharan Africa, and even parts of North America and Europe, are especially vulnerable.

Here’s the good news—increasing your intake of fruits and vegetables can make a real difference. Many fruits and veggies are packed with calcium (think kale and oranges), vitamin C (hello, bell peppers and strawberries), and iron (yes, spinach really helps!).

Take action today by adding more plants to your plate. Small steps, like choosing seasonal veggies or snacking on fruit, can have a profound impact on your health.
