- Eating more nuts might help people with diabetes mellitus (DM) reduce their cardiovascular disease (CVD) and mortality risk.
- Peanut butter is included.
Why this matters
- These authors call the findings “novel evidence” supporting adding nuts to the diet, although a previous study has linked nut intake to reduced CVD risk in the general population.
- Eating 5+ servings (serving=28 g)/week vs
- CVD incidence: 0.83 (0.71-0.98; Ptrend=.01).
- Coronary heart disease incidence: 0.80 (0.67-0.96; Ptrend=.005).
- CVD mortality: 0.66 (0.52-0.84; Ptrend<.001>
- All-cause mortality: 0.69 (0.61-0.77; Ptrend<.001>
- Tree nut intake was linked to reduced risks across the board, but peanut consumption only to reduced all-cause mortality.
- No effects on stroke incidence, cancer mortality.
- Nut consumption before DM diagnosis was also linked to risk reductions.
- Prospective analysis; 16,217 people with DM, Nurses’ Health Study/Health Professionals Follow-Up Study.
- Nut intake via questionnaire.
- Funding: NIH.
- Observational, so no causation established.
- Nut intake via self-report.
