The Claim
Peanut butter consumption is not associated with lower all-cause or cause-specific mortality in middle-aged U.S. adults, despite similar intake levels to nuts.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Middle-aged adults in the U.S. who eat peanut butter do not have lower rates of death from any cause compared to those who eat similar amounts of nuts.
See the scientific wording
Peanut butter consumption is not associated with lower all-cause or cause-specific mortality in middle-aged U.S. adults, despite similar intake levels to nuts, suggesting differences in food composition or consumer behavior may negate potential benefits.
Peanut butter often contains added sugars and unhealthy fats that trigger inflammation in the body and make it harder for cells to respond to insulin. This leads to higher blood sugar and fat levels over time, which increases the risk of heart disease, diabetes, and other conditions that shorten life. Nuts do not have these additives, so they do not cause the same harm.
What the research says
1 studyPeople who ate peanut butter didn’t live longer than those who didn’t, even though they ate about as much as people who ate nuts — and nut eaters did live longer. This suggests peanut butter might not be as healthy as nuts, maybe because of how it’s made or the habits of people who eat it.
