What does science say about the claims Stan Efferding makes about the Vertical Diet and how beef (red meat) is a better protein source than chicken and should be eaten daily? Are there any detrimental health effects following such a red meat based diet? Also, when would it be necessary to test vitamin deficiencies?
It contradicts that.
Potentially, but all in all if the calorie level, protein, and fiber levels are the same then maybe not such a big deal.
If someone is symptomatic or an at-risk population per the USPSTF recommendations.
