What are some hidden nutrient deficiencies and what can I do to fix them?

Subclinical nutrient deficiencies, though asymptomatic in the short term, can lead to significant long-term health issues. Ensuring a diverse, nutrient-rich diet is crucial for overall health.

- Vitamin B1 Deficiency: Essential for brain function, a lack of vitamin B1 (thiamine) can result in cognitive decline and conditions like Wernicke-Korsakoff syndrome. Sources include legumes and pork.

- Niacin Deficiency: Severe deficiency in niacin (vitamin B3) causes pellagra, marked by diarrhea, dermatitis, dementia, and death. Niacin is found in poultry, fish, and nuts.

- Vitamin A Deficiency: Critical for vision, especially night vision, vitamin A deficiency can lead to night blindness and severe cases of blindness. Key sources include liver and leafy greens.

- Vitamin E Deficiency: As an antioxidant, vitamin E protects cells and supports immune function. Severe deficiency can cause muscle weakness, vision problems, and heart arrhythmias. Sources include nuts, seeds, and vegetable oils.
