Dear Mark: Saturated Fat

fatfreeDear Mark,

In one of last week’s Cheap Meat discussions, you said something about ratios and saturated fats and how saturated fats aren’t really the issue in your mind. I might have been missing something in the conversation. Can you fill me in?

The issue of ratios within animal fat was raised by reader Jaana as she shared Cordain’s discussion of the varying polyunsaturated fat content and corresponding omega ratios in muscle meat versus different organ meats. Cordain compares wild game (that we can assume are comparable to the meats our pre-agricultural ancestors ate) with the domestically raised livestock we eat today. As a general rule, the muscle meat of conventional livestock today has less polyunsaturated fat than wild game does. Conventional domestic meat also has more saturated fat than wild game.

Diet Change and Partner Dynamics

couple1Researchers at Ryerson University in Toronto examined the response of significant others to their partners’ dietary changes. They also compared significant others’ reporting of their response to the “changing” partner’s perception of that response.

The researchers conducted interviews with 21 people making dietary changes–most in response to a medical diagnosis–and with their partners or significant others. ‘By examining the perspectives of significant others, we hoped to deepen understanding of the social nature of dietary change,’ Dr. Paisley explains. The partners’ emotional responses varied widely: from co-operation and encouragement to skepticism and anger. In most cases, the significant others described themselves as playing a positive, supportive role. Some facilitated the change by joining in the new diet, or by changing their shopping or cooking habits. Others helped by monitoring the dietary change, finding and sharing information, or providing motivation … However, in some cases, the person trying to make a change felt their partner had a negative impact on their efforts — for example, by eating ‘forbidden’ foods in front of them. In these cases, the significant others did not view their response as negative. In only one case did both partners agree that the significant other played a neutral role.

King Corn – Coming to PBS!

Back in September, we told you about a new independent film called King Corn that, as the title suggested, was poised to blow the roof off the concept of the American food industry by telling us that everything – and I mean everything – we eat contains corn!

Your Belly Bone’s Connected to Your Brain Bone

bigbellyA study published online in this month’s Neurology suggests that people whose waistline expands once they hit age 40 are more likely to develop dementia in their 70s than their slimmer peers.

For the study, researchers measured the abdominal fat of 6,583 people between the ages of 40 and 45 living in Northern California. After an average of 36 years, 16% of participants had developed dementia.

Based on this data, the researchers determined that those with the highest abdominal fat measurements were roughly three times more likely to develop dementia than those with the lowest levels of abdominal fat. These findings held true regardless of whether the individual was of normal weight overall, overweight or obese, although the researchers note that future dementia risk was highest among obese individuals with high abdominal fat measurements. According to researchers, women were more likely than men to have high abdominal fat levels, along with non-whites, those with less than a high school level of education, smokers, and people with high blood pressure, high cholesterol or diabetes.
