Ramirez took to Instagram last night to defend himself, saying: “I would NEVER take anything to jeopardize everything I worked so hard to achieve these last 5 years. The only thing that makes any sense is that there was a contaminated substance that I was taking. All the products I was taking are 100% natural. I am personally paying out of my pocket to continue my appeal, and have all the 8 products I was taking tested. I will disclose all of these, which I already did to CF which they stated were all legal and be 100% transparent with everyone this week.”
CrossFit, Inc. has been variously criticized and praised for its unorthodox approach to social media. This approach has included publishing articles and tweets about non-fitness topics (including politics, philosophy, and poetry) as well as directly interacting with other social media users and critics of the company's program.
Excluding foods. The exclusion of entire categories of commonly eaten foods like whole grains and dairy requires frequent label reading in the supermarket and in restaurants. It may also increase the risk of deficiencies such as calcium, vitamin D, and B vitamins, if these nutrients are not consistently eaten from the allowed foods or a vitamin supplement. For example, there are some nondairy calcium-rich foods that are absorbed well by the body such as collard and turnip greens or canned bone-in sardines and salmon, but you would have to eat five or more servings of these greens and fish bones daily to meet recommended calcium needs. (Note that some greens like spinach that are touted to be calcium-rich also contain oxalates and phytates that bind to calcium so very little is actually absorbed.) One small, short-term intervention study of healthy participants showed a 53% decrease from baseline in calcium intake after following a Paleo diet for three weeks.  Furthermore, the exclusion of whole grains can result in reduced consumption of beneficial nutrients such as fiber and thus may increase one’s risk for diabetes and heart disease.
Transformed cells adapt metabolism to support tumor initiation and progression. Specific metabolic activities can participate directly in the process of transformation or support the biological processes that enable tumor growth. Exploiting cancer metabolism for clinical benefit requires defining the pathways that are limiting for cancer progression and understanding the context specificity of metabolic preferences and liabilities in malignant cells. Progress toward answering these questions is providing new insight into cancer biology and can guide the more effective targeting of metabolism to help patients.
