Many of my blogs report on the power of a
healthy diet and lifestyle in mitigating disease risk. In a recent twist on
this theme of diet and health, two current studies appeared in the media this
month regarding the relatively quick and detrimental results of eating and
Beverages Increased Risk Factors For Heart Disease
A recent study using the National Health and Examination Survey Data showed
a dose-related response of an increased risk for cardiovascular disease (CVD) mortality
with added sugar. (1)
In this parallel-arm, nonrandomized, double-blinded intervention study,
researchers examined the effects of a high-fructose corn syrup beverage at
zero, low, medium, and high proportions of energy requirements in relationship to
lipid/lipoprotein risk factors and uric acid levels in adults within 2 weeks. Unfortunately,
the placebo (zero) was aspartame, which could have confounded results. Still,
the authors concluded (1-2):
Conclusions: Consuming beverages
containing 10%, 17.5%, or 25% Ereq from HFCS produced dose-dependent increases
of circulating lipid/lipoprotein risk factors for CVD and uric acid within 2
wk. These results provide mechanistic support for the epidemiologic evidence
that the risk of cardiovascular mortality is positively associated with
consumption of increasing amounts of added sugars. (1)
A recent study
also showed that diet soda is not good for the waistline (3), so you may want
to swap these sweetened liquids for plain water or herbal teas.
Junk Food Does To Your Body In 5 Days
looked at how a short-term change in diet impacted 12 healthy, young males’
metabolism. The study had two parts. One was to determine the effect of a high-fat diet on
skeletal muscle’s insulin sensitivity. The second part was to assess how the metabolism
responded from a fasted to fed state using a high-fat meal before and after 5
days on the high-fat diet (HFD). The authors report:
Conclusions:Our findings provide evidence for early biological adaptations to high-fat
feeding that proceed and possibly lead to insulin resistance.
News for Pistachio Lovers
I can’t leave you
with all negative news without a solution!
Recent research showed
that pistachios may have beneficial effects on pathways related to pain,
inflammation, and for cardiovascular health. Healthy fats can also help
modulate blood sugar and cravings. So, maybe you can substitute a few nuts for
healthy calories when those unhealthy-fat, sugary temptations hijack your
