A health expert has issued a cautionary alert that a prevalent deficiency could be the reason behind your feelings of sadness. This expert estimates that this problem impacts more than a billion individuals globally.
With the onset of winter, many people observe a change in their emotional state. The cold weather and shorter daylight hours often lead to a sense of melancholy. While seasonal affective disorder (SAD) could be a contributing factor in some cases, there might be another underlying cause.
In a video posted on the social media platform TikTok, Doctor Sermed Mezher emphasized the significance of iron deficiency. Iron plays a vital role in the body, essential for oxygen transport in the blood and various metabolic functions.
Dr. Mezher stated, “Iron deficiency is the most widespread nutritional shortfall worldwide, affecting over a billion people.” He explained how it can impact dopamine, commonly known as the “feel-good” hormone.
He further elaborated, “The influence of iron on dopamine extends beyond oxygen transport. Dopamine production involves an amino acid called tyrosine, and the enzyme responsible for the initial step requires iron to function.”
“In cases of iron deficiency, disruptions in dopamine-related pathways have been documented, affecting emotions like happiness, reward, self-control, and social interactions.”
Fortunately, addressing this issue is possible. Dr. Mezher highlighted, “The positive news is that replenishing iron stores can restore these pathways to normal function. Taking iron with vitamin C and avoiding caffeinated beverages two hours before and after can expedite the process.”
According to the NHS, symptoms of iron deficiency anemia may include fatigue and weakness.
If you suspect you may have iron deficiency, it is advisable to consult your healthcare provider for blood tests to confirm the condition.
Making dietary adjustments can help increase iron levels. Foods rich in iron include red meat, poultry, fish, beans, and leafy greens.
It is recommended to limit consumption of certain foods and drinks, as excessive amounts can hinder iron absorption. If incorporating iron into your diet proves challenging, a consultation with a specialist dietitian may be beneficial.
The NHS advises, “Consuming 17mg or less of iron supplements daily is generally safe. However, follow higher dosage recommendations if advised by a medical professional.”
