NOTE TO READERS: When this project lost substantial funding at the end of 2018, I lost the ability to continue publishing criteria-driven news story reviews and PR news release reviews - once the bread-and-butter of the site going back to 2006. The 3,200 archived reviews, while still educational, are getting old and difficult for me to technically maintain on the back end of the website. So I am announcing that I plan to remove these reviews from the site by April 1, 2021. The blog and the toolkit - two of the most popular features on the site - will remain. If you wish to peruse the reviews before they disappear, please do so by the end of March 2021. After that date you may still be able to access them via the Internet Archive Wayback Machine - https://archive.org/web/.

Eating your way to lower cholesterol

Our Review Summary

This article puts several disparate pieces about dietary interventions that can be made to improve cholesterol profile together in one place in a helpful manner. The article covered the results of a recent study that showed that the addition of what was terms a ‘portfolio of heart friendly foods’ to the diet can result in a significant reduction in the level of ‘bad’ cholesterol. This ‘porfolio’ included viscous fiber, soy protein, plant sterols and nuts. What the article failed to mention that this cholesterol reducing portfolio was added to a heart healthy diet, not a standard American diet which is higher in saturated and trans fats. Thus it may be necessary to first be consuming a diet low in these fats before adding the portfolio components to the diet will results in a decrease in LDL or ‘bad’ cholesterol. The article did include examples of the types of foods to be added with an explanation for the mechanism by which it appears that each lowers cholesterol.

The article began with material on an updated approach to heart healthy eating which includes the notion that is possible to work any food into diet by considering portion size and comensating with other foods; and secondly that the consumption of foods (such as eggs or shellfish) that are high in cholesterol does not have a large affect on circulating levels of cholesterol. The article could have done a better job of setting the stage for readers to evaluate the impact of the dietary changes described by more clearly detailing the benefits and providing information on the potential harms and costs.

Criteria

Does the story adequately discuss the costs of the intervention?

Not Satisfactory

There was no discussion about how the addition of these foods affected the total food budget for the study participants.

Does the story adequately quantify the benefits of the treatment/test/product/procedure?

Not Satisfactory

While the article does provide some comparison between the group of individuals who were most compliant with including all the diet additions (a 20% reduction) and those who “fell off the wagon” (a 10% reduction), the article should have included absolute to better enable the reader to understand whether these changes were meaningful to them.

Does the story adequately explain/quantify the harms of the intervention?

Not Satisfactory

There was no discussion of any potential downsides to the dietary changes recommended, though the article to start off with a section that touched on the idea that dietary changes can be ‘negotiated’. The addition of foods to a diet without reduction in intake of other food will lead to an increase in total calories consumed which could lead to weight gain.

Does the story seem to grasp the quality of the evidence?

Satisfactory

The evidence provided comes from a study published in the American Journal of Clinical Medicine which was cited in the article. The article did not clearly represent that the foods added to the diet were added to a heart healthy diet. However, the article did include the extent to which ‘bad’ cholesterol was lowered in those adhereing rigidly and less strictly to the diet.

Does the story commit disease-mongering?

Satisfactory

Although the article did cast heart disease as’ the country’s No. 1 Killer’, the overall tone was not one of disease mongering.

Does the story use independent sources and identify conflicts of interest?

Satisfactory

There were several experts interviewed for this story and the study published in the American Journal of Clinical Nutrition was mentioned as the source of the dietary information provided.

Does the story compare the new approach with existing alternatives?

Not Satisfactory

The article reported on a study in the American Journal of clinical Nutrition that found these food additions lowered cholesterol levels as much as “first-generation statin drugs”. There was no information on effectiveness of other drugs to lower cholesterol or interventions such as weight loss or exercise.

Does the story establish the availability of the treatment/test/product/procedure?

Satisfactory

The article provides a very clear list of the heart friendly foods that contain each of the categories of cholesterol lowering foods. However, it neglected to mention that the research only demonstrated that these foods lower cholesterol when added to an already heart-healthy diet (i.e. < 7% of calories from saturated fat and < 200mg dietary cholesterol/day)

Does the story establish the true novelty of the approach?

Satisfactory

The three recommendations about diet to lower cholesterol are not new and are not presented as novel. However, putting these concepts together in one place is handy.

Does the story appear to rely solely or largely on a news release?

Satisfactory

This article does not appear to rely on a press release.

Total Score: 6 of 10 Satisfactory
