Short Summary
Main recommendation: Ben Bikman argues that the DASH diet's heart-health benefit should not be credited mainly to its low-fat and low-salt framing, and that a higher-fat version of DASH may improve blood lipids as well as the standard version improves blood pressure. He cites a 2016 study by Chiu et al. comparing the two versions, and he frames the findings as a reason to reconsider how the DASH diet is taught.
Key Points
- DASH stands for "Dietary Approaches to Stop Hypertension," and it was identified as a diet that slightly reduces blood pressure, which matters because lower blood pressure can reduce heart attack and heart disease risk.
- Bikman says the DASH diet is usually promoted as low-fat and low-salt, but it also includes reduced refined sugars and starches, a combination he says is often overlooked.
- In the Chiu et al. 2016 study, a high-saturated-fat DASH version, with full-fat dairy encouraged liberally, produced the same blood pressure reduction as standard DASH.
- The high-fat version produced larger drops in triglycerides and VLDL, while LDL stayed the same across both groups.
- Bikman argues that triglycerides and VLDL predict heart attack risk better than LDL does, citing a recent paper where people with lower VLDL but higher LDL had the lowest heart attack risk.
Details Worth Noting
- Concrete instructions: The transcript gives no step-by-step meal plan, amounts, or dosing. The only actionable point is the comparison itself: when choosing a DASH-style approach, consider that the high-fat version was tested in the study with liberal full-fat dairy, which is the opposite of the commonly taught low-fat version.
- The study comparison involved a version with substantially more saturated fat (multiple times more) than the standard group, so the findings describe that specific tested diet, not all high-fat eating. Bikman states that every cardiologist and dietitian recommends DASH for heart disease concerns, and acknowledges (via audience comments) that some dietitians have updated their views while the most dogmatic ones remain stuck on outdated ideas.
- He calls the blood pressure benefit of DASH "modest," and says the main reason people adopt it is blood pressure reduction.
- He describes the standard DASH diet as difficult to stick with, suggesting that is one reason few people adhere to it.
Bottom Line
The DASH diet's blood pressure benefit appears in both low-fat and high-saturated-fat versions in the cited study, and Bikman argues its lipid effects deserve more attention than its low-fat, low-salt reputation suggests.
