Nutrigenomics (NutraGenomics) effects of food on gene expression

In my nutrition book (1) I came across the term 'nutrigenomics', the study of the effects of foods and food constituents on gene expression.

I found that there is hope for people with inherited blood conditions like Cooley's anemia (a.k.a.Thalassemia) or sickle cell anemia. www.encoderesearch.com/L

The article says that "Nutrients and foods can now be safely designed to encode transporters, receptors, carrier proteins, enzymes and hormones."

Apparently L-Arginine (an amino acid) is involved in Thalassemia.
I found a video that shows what foods to eat to get adequate L-Arginine.

My textbook (2) gave an interesting example of gene expression in agouti mice due to food consumption.

It is possible for food to turn on and off genes which alters the gene expression in agouti mice. Well nourished mothers give birth to normal offspring, but pregnant mice who eat a deficient diet give birth to yellow, fat mice. This article states that dietary factors can prevent the agouti gene from being turned on.

    mary this is so interesting. I'm learning about how food helps us get better. In 2006 i started on supplements which started turning my life around. little by little i'm getting there. I know when i don't have my green smoothies, i feel drained. there is something in those freggies. I hope this helps you in your journey.
