About $2.4 trillion or 17% of the US GDP in 2007 was spent on "health care" (not including diet whatsoever). This amounts to about $7,900 per person.
Americans spend more than $1 trillion on food each year. However, the food bought is directly implicated in the degenerative diseases, and the cost of health care. This equates to ~$3,000 per person.
Between health care and food Americans spend $3.4 trillion dollars, or about $11,000 per person or ~25% of the GDP.
Total Cost for recommended supplements and some foods: ~$2,200 per year. Averaging $350/month for groceries this equivalent to $4,200 per year, for a total of ~$7,000 per year per person to have one of the healthiest possible diets.
