In the news is yet another powerful argument against reductionism or nutritionism…aka vilifying or glorifying one specific nutrient and ignoring the entire packaging of the food within which it is contained.

VS CholesterolAs the USDA ramps up to set the latest 2015 Dietary Guidelines, as they do every five years, a very interesting – and somewhat surprising – nuance emerged from the Dietary Guidelines Advisory Committee. They are considering withdrawing longstanding warnings about dietary cholesterol. Apparently, there is controversial evidence on whether dietary cholesterol directly impacts blood cholesterol levels. As of now, the 2010 Dietary Guidelines recommend no more than 300 milligrams of dietary cholesterol per day, which is just about the amount found in a single egg. Marion Nestle hypothesizes whether perhaps egg industry-funded research may play a role in this possible decision.

PCRM Fat and CholesterolDr. Neal Barnard clarifies the confusion of all of this in this blogpost, reminding us why “fat and cholesterol are the Bonnie and Clyde of the culinary world.” He reiterates that “bad” fat and cholesterol are as bad for you as ever. The products that harbor them—meat, dairy products, and eggs—are best left off your plate. People following plant-based diets have healthier body weight, better cholesterol levels, lower blood pressure, and much less risk of diabetes.

Dr. John McDougall wrote this excellent breakdown in his newsletter (and I quote):

Significant amounts of cholesterol are found only in animal foods. Plants (starches, vegetables, and fruits) are “cholesterol-free” foods.

The problem is “the animal foods” – blaming individual components (i.e. cholesterol) is a risky business:

500 Kcals Plants vs. AnimalsIn common, animal foods (meat, poultry, eggs, dairy, and seafood) are:
High in fat and/or high in protein
Contain no dietary fiber
Contain no energy giving carbohydrate (mammal milk is the exception)
High in environmental contaminants (POP)
Transmitters of microbes (zoonosis) – bacteria, viruses, parasites, prions
Expensive (money) sources of calories

Meat, poultry, eggs, and dairy are:
Deficient in essential fats (omega 3 and omega 6)
Deficient in vitamin C
A (the) major source of global warming gasses and environmental damage (land and water)
Loaded with allergens that cause autoimmune diseases through molecular mimicry
Meat, poultry, and fish are deficient in calcium and dairy is deficient in iron

*Deficient means that they are unable to meet dietary needs of children and adults

SynergyIn my new book, The Vegiterranean Diet, one of the Veg 10 guidelines includes “Pick Proper Packaging.” To sum up what that means, nutrients come wrapped up with hundreds or thousands of other nutrients and they work synergistically together to nourish your body when consumed. This is why isolating a single nutrient into a supplement is either ineffective when compared to eating intact foods or can even be dangerous because it behaves differently than it does in its natural format.

Ultimately, it remains the case that we need to focus on the overall packaging of food and totality of the diet, and heed attention to the preponderance of scientific data (despite how certain facts seem to ebb and flow with new information) in order to really gauge health-promoting dietary choices.
