High Fat Diet Decreases Metabolism and Increases Anger and Hostility



A new study finds that saturated fat decreases metabolism and physical activity, and increases anger and hostility.


 

HIGH FAT DIET DECREASES METABOLISM AND INCREASES ANGER AND HOSTILITY

As I have written about extensively in my bestselling book, A Cancer Prevention Guide for the Human Race, a diet low in saturated fat and meat products, such as the Mediterranean diet, has been linked to a decreased risk of cancer (and cardiovascular disease) when compared to the traditional Western diet, which is rich in saturated fat and meat. Now, a new study has linked a Mediterranean-type diet, low in saturated fat, to other potential health benefits, including greater levels of physical activity, a higher metabolic rate, and, somewhat surprisingly, less angry and hostile moods. This study appears in the current issue of the American Journal of Clinical Nutrition.

In this prospective randomized clinical study, 32 young adults were separated into two groups. The first group used cooking oils high in saturated fat, while the second group used cooking oils low in saturated fat and high in monounsaturated fat. After three weeks, both groups were “crossed over,” and had their cooking oils switched for an additional three weeks. (This clinical study’s “crossover” design is a powerful means of eliminating potential biases that can lead to false conclusions.) Another important aspect of this study was that all food consumed by the study’s volunteer research subjects was provided (and controlled) by the researchers. Moreover, the food provided to both groups of study volunteers was the same, and only the cooking oil differed between the two study groups.

All research volunteers were continuously assessed with regards to physical activity levels and resting metabolic rates (“resting energy expenditure”). Due to the observed differences in physical activity levels between the two groups of volunteers, the researchers also subjected study volunteers to a validated mood assessment questionnaire, to see if differences in mood might account for the significantly different levels of physical activity between the two groups of research volunteers.

The results of this intriguing prospective randomized clinical study were quite interesting. Firstly, continuous measurements of physical activity showed that the monounsaturated oil (Mediterranean-like diet) group was 12 percent more active, physically, than the saturated fat group (Western-type diet). Secondly, the resting metabolic rate of the monounsaturated oil group was almost 5 percent higher than that of the saturated fat cooking oil group, suggesting that the young adults who were consuming primarily monounsaturated fat were burning more calories at rest than the group that was using saturated fat. Finally, the monounsaturated fat group scored significantly lower on the anger-hostility scale of the mood assessment questionnaire than the volunteers who were using cooking oil containing saturated fat.

To summarize, this innovative prospective clinical research study found that a Mediterranean-like diet, low in saturated fat, was associated with increased levels of physical activity, a higher resting metabolism rate, and less anger and hostility, when compared to a Western-like diet that was rich in saturated fat. These findings add further evidence to the data that I extensively discuss in A Cancer Prevention Guide for the Human Race, showing that a Mediterranean diet low in saturated fat and meat products, and high in unsaturated oils, whole grains, fresh fruit and vegetable, fish, and poultry, is an important strategy for good health.

Hold the Bacon: Processed Meats Linked to Early Death



A new study links the consumption of processed meats with a significant risk of early death.


 

HOLD THE BACON: PROCESSED MEATS LINKED TO EARLY DEATH

As I extensively discuss in my bestselling book, A Cancer Prevention Guide for the Human Race, red meat and processed meats (such as bacon, sausages, and luncheon meats) have been directly linked to an increased risk of multiple different types of cancer, including cancers of the breast, prostate, esophagus, stomach, pancreas, kidney, bladder, colon, and rectum. Moreover, diets rich in these meat products are also associated with a higher risk of that other great killer of mankind, cardiovascular disease.  Now, a newly published public health study puts the impact of a meat-rich diet into stark perspective. This important new clinical study appears in the current issue of the journal BMC Medicine.

Nearly 450,000 men and women between the ages of 35 and 69 have participated in a huge ongoing prospective public health study, the European Prospective Investigation into Cancer and Nutrition (EPIC), making this one of the largest prospective clinical research studies ever undertaken. All of these study volunteers were without clinical evidence of cancer, stroke, or cardiovascular disease at the time they entered into this clinical study. At the time when data from the EPIC study was collected for this analysis, after almost 13 years of follow-up on average, 26,344 study volunteers had died since enrolling in the study.

Following extensive statistical analysis of the huge amount of data collected in this study, the increased consumption of processed meats was linked to a 44 percent increase in the risk of death from all causes, including cardiovascular (heart) disease and cancer. Red meat was also associated with an increase in the risk of death due to all causes, although not to the same extent as was observed with processed meats. (As with multiple previous studies, this study also found no association between the consumption of poultry and an increase in the risk of death from any cause.)

Based upon their analysis of the data, the researchers who conducted this gigantic public health study concluded that more than 3 percent of the deaths observed in this study could have been prevented if all study volunteers had decreased their processed meat intake to less than 20 grams (0.7 ounces) per day.

As I discuss in A Cancer Prevention Guide for the Human Race, our dietary and other lifestyle choices can have an enormous impact on our overall health, including our risk of cancer and cardiovascular disease. If you seek to minimize your risk of these two great killers of modern mankind, and you wish to begin living an evidence-based cancer prevention lifestyle now, then get your copy of A Cancer Prevention Guide for the Human Race from your favorite bookstore!

Low-Carb Diet and Risk of Death

 

Welcome to Weekly Health Update


“A critical weekly review of important new research findings for health-conscious readers”


LOW-CARB DIET AND RISK OF DEATH

The debate regarding the potential health benefits of low-carbohydrate diets has gone on for over four decades now.  During this period, the pendulum has swung, repeatedly, back and forth between “low-carb” and “high-carb” diets, combined with controversies regarding low-fat versus high-fat diets, as various diet and health gurus have weighed in with their recommendations.  (Witness one of the more popular and enduring of these “have it your way” dietary fads, the now discredited Atkins Diet, which advocated a reduction in carbohydrate intake combined with a free pass on meat consumption, and other animal-based sources of fat and protein.)

Currently, there is really no meaningful controversy regarding the linkage between meat consumption and an increased risk of cardiovascular disease and cancer.  However, the impact of dietary carbohydrate intake on health continues to be the subject of some debate.   Unfortunately, as is often the case regarding debates about lifestyle- and diet-related health factors, there is very little high-level clinical research data evidence available to support the more ambitious claims made by “experts” at either spectrum of the carbohydrate debate.  Now, a newly published study, which appears in the current issue of the Annals of Internal Medicine, offers a fresh, evidence-based assessment of the impact of carbohydrate and meat intake on the risk of early death. 

In this prospectively conducted cohort study, which was funded by the National Institutes of Health, the results of two very large prospective public health studies were combined.  More than 85,000 women who participated in the vast Nurses’ Health Study, and nearly 46,000 male physicians who participated in the Health Professionals Follow-up Study, were included in this analysis.  These healthy female and male volunteers were without clinical evidence of cardiovascular disease, diabetes, or cancer when they entered into these studies.  An almost unprecedented duration of clinical follow-up was available for these two enormous groups of research volunteers, which makes this combined cohort study extremely powerful.  On average, the male study volunteers have already been followed for 20 years, while the women volunteers have been followed for an average of 26 years.  All of these 129,716 men and women completed multiple validated diet questionnaires at various time points in these two clinical studies, and the data collected from these questionnaires was then used to analyze the impact of diet on mortality (death) risk among this huge group of nurses and physicians.

Two sub-groups of volunteers were assessed, based upon their dietary preferences, and these two sub-groups of men and women were then compared with the remaining study volunteers.   The first dietary preference sub-group consisted of men and women who preferred a low-carbohydrate diet associated with the frequent intake of meat and other animal-based foods (along the lines of the Atkins Diet), while the second sub-group consisted of men and women who routinely consumed a low-carbohydrate diet that emphasized vegetable and fruit sources of protein (instead of animal sources of protein).

Over the very long duration of the two combined studies, 12,555 deaths occurred among the women (including 2,458 deaths due to cardiovascular disease).  Among the men, there were 8,678 deaths (including 2,746 deaths due to cardiovascular disease).

In the group of men and women who favored an Atkins-like diet, emphasizing a low carbohydrate intake but liberal meat consumption (and other animal-based foods, as well), the risk of premature death from any cause (when compared to a low-carb, low-meat diet) was elevated by 23 percent.  This same dietary preference was also associated with a 14 percent increase in the risk of death due to, specifically, cardiovascular disease.

In contrast, the men and women who consumed a diet low in both carbohydrates and animal products appeared to significantly reduce their risk of death due to all causes, as well as their mortality due to cardiovascular disease, specifically.  In this group of research volunteers, mortality due to any cause was reduced by 20 percent, while death due to cardiovascular disease, specifically, was reduced by 23 percent.

The findings of this very large prospective public health study, with its extremely long duration of clinical follow-up, confirms the findings of other recent (and less powerful) small clinical studies that a diet rich in vegetables, but low in both carbohydrates and animal-derived foods, confers a very significant benefit in terms of the overall risk of death, and the risk of death from cardiovascular disease, in particular.

Excessive carbohydrate intake has been previously shown to increase the risk of diabetes, obesity, cardiovascular disease, cancer, and other serious illnesses.  At the same time, increased meat intake has also been clearly shown to raise the risk of many of these same life-threatening illnesses, as well.  From this huge prospective cohort clinical study, we can see highly significant health benefits associated with long-term adherence to a healthy diet rich in vegetables and low in carbohydrates and animal-derived foods.  (And there are not many health benefits that can trump a significant reduction in your risk of premature death!)

 

For an evidence-based review of the critical importance of diet in a cancer prevention lifestyle, watch for the publication of my new landmark book, “A Cancer Prevention Guide for the Human Race,” later this month.
