Can Malnutrition Cause Long-Term Vitamin Deficiency?

Unfortunately yes it can and you will need supplements and have a healthier diet now. You can look at the Paleo diet and bounce back to working around processed foods from the grocery store can help but I would stick to organic foods and look at the dirty dozen list when shop at grocery stores so you're not deceived on what you're buying. Be careful shopping! I have learned Bill Gates bought farming land to make ultra processed foods to eat at the grocery like fast food that is bioengineered causing so much chaos to our bodies, just be vigilant when you shop and aware. keep in mind grass fed meats are the healthier. I have something like a chemical imbalance myself mine is a combination of deficiency of neurological and cognitive health but I found solutions that are helping me.
