Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...Tell Me More
Shrimp have long been on the average dietitian’s “bad” list. The belief was that lobster, crabs, clams, shrimp and other shellfish were high in cholesterol, and therefore detrimental to cardiovascular health. But according to the L.A. Times, the oft-cited information is completely wrong. Accurate measurements reveal that shellfish – even shrimp – are quite low in cholesterol.
Of course, the theory that dietary cholesterol somehow translates to high LDL blood cholesterol – and further, heart disease – is one of rapidly eroding merit. (See Mary Enig’s critique of the lipid hypothesis for more research and information on this.) In truth, avoiding particular foods because of their cholesterol content – whether it’s grass-fed beef or eggs or shellfish – is not only unnecessary, but possibly foolish. In keeping with our Primal Health discussions here at MDA, I am firmly convinced that the national nutritional guidelines which recommend strict avoidance of natural, nutritious foods containing saturated fat – and cholesterol – in favor of highly refined products made from grains are clearly contributing to our epidemics of obesity, type 2 diabetes, “syndrome X”, and possibly depression and arthritis. And the list goes on…
Now, whether we ought to be eating shellfish in light of environmental considerations is another question. Clean, fresh shellfish of all sorts are high in many important nutrients and our primal ancestors certainly ate oysters, shrimp, abalone, clams, and lobster in abundance – depending, of course, on geographical location.
