|Ew--that isn't good.|
While we are not exactly 18th century sailors keeling over with scurvy, our various "diets" and "food plans" and otherwise unbalanced eating behavior can result in issues, according to the Food Technology Institute.
I have personal experience. I have intestinal issues and tend to steer away from the recommended bales of veggies and also from dairy, so when my hair started to fall out a month or two ago, the dermatologist checked my blood for Vitamin B1, folic acid, and iron (my thyroid tests were normal) . Or wanted to--I could not get a ride to the lab, so am looking up foods I can emphasize to maybe up these levels if indeed they are the culprits.
The Food Technology Institute says people in weird dietary spaces need to pay attention to getting essential nutrients.
VEGETARIAN AND VEGAN. As much as 20% of the global population is one of these. These people must eat legumes, soy products, nuts, seeds, and whole grains--no meats, poultry or seafood. They may be higher in calcium and fiber, but lower in Vitamin D. Pay special attention to calcium, Vit D, Vit B12, protein, omega-3 fatty acids, iron, and zinc.
HUGH PROTEIN/LOW CARB/GLUTEN-FREE. Emphasis here is on eliminating carbs and often whole grains. You could be missing out on B vitamins and fiber. Eat more quinoa, brown rice, and sweet potatoes.
PALEO. supposedly based on what cavemen ate, the idea here is to eat lean meat, seafood, nuts, fruits, veggies, and healthful oils. No grains, legumes, dairy, and foods with refined sugar and lots of salt. These people need to supplement with folate, B vits, calcium, and Vit D.
OK...I don't see my situation there. Back to the research.
