Moderate Alcohol Consumption Increases High Fat and Savory Food Intake

One of the understood reasons why wine and alcohol in general are good complements to a meal is that it has been shown to stimulate short-term food intake. While is it is not known what exactly causes

this increase in food intake after alcohol consumption, there are several theories. First, it is possible the consumption of alcohol reduces the signals that tell the stomach that it is full. Second, alcohol consumption could trigger an increase in reward signaling of food (in other words, telling the brain that “ooo that food is really good for you!”, when in fact it may not be).

A new study published in the journal Appetite aimed to study the effect of alcohol consumption on food intake and to gain a better understanding of the mechanism behind this phenomenon.

24 healthy men were recruited for this study and were randomly assigned to consume either a vodka/orange juice mixture (20g alcohol; considered “moderate” levels) or orange juice without the alcohol. After consuming the beverage, participants were asked to either eat 40 gram piece cake or “pretend” to eat cake. Known as “modified sham feeding”, those participants asked to “pretend” to eat the cake had to put the cake in their mouths, process/chew it per the study instructions, and then spit it back out into a cup without actually swallowing any of it. Those asked to eat the cake did the same processing/chewing procedure, but actually swallowed the cake instead of spitting it out.

The food reward was determined by the amount of food ingested during a lunch 45 minutes after the alcohol/cake intervention. Foods were categorized as being high fat, low fat, savory, and sweet. Participant “liking” and “wanting” of these food categories was also recorded.

Important Findings:

Part of the Mediterranean diet, nuts are considered an important part of daily consumption, and is frequently recommended to those without specific allergies.

A new study in the journal Preventative Medicine has examined the effect of nut consumption on. peripheral arterial disease. While nut consumption is linked to lower risk of certain cardiovascular diseases, the association with the specific cardiovascular disease, peripheral arterial disease, is unknown.

This study followed 3,312,403 Americans between 2003 and 2008 who had voluntarily undergone vascular screening tests. Average age was 63.6 +/- 10.6 years, with 62.8% of participants being women, and 86.2% being white.

Nut consumption, diet, and other lifestyle habits were determined for each participant using self-reported questionnaires.

Diagnosis of peripheral arterial disease for participants was determined using systolic blood pressure measurements in both ankles.

Hyperlipidemia, diabetes, and hypertension were determined by physician diagnosis.

Important Findings:

  • Out of 3,312,403 participants, there were 219,527 cases of peripheral arterial disease (6.7%).
  • About half of the study population ate nuts fewer than once per week.
  • There was a negative association between nut consumption and presence of peripheral arterial disease.
  • Daily nut consumption was associated with 21% lower odds of developing peripheral arterial disease compared with folks consuming nuts less than once per month.

The results of this study suggest that nut consumption reduces the risk of peripheral arterial disease. Specifically, eating nuts every day lowered the risk of developing peripheral arterial disease by 21%

compared with people who ate nuts less than once per month.

The huge sample size in this study strengthens the results, though the self-reporting nature of these kinds of lifestyle questions could skew the results slightly. Regardless, these results show promise that a daily nut regime might help reduce the risk of peripheral arterial disease.
