Key Takeaways
- Research suggests that daily consumption of peanut butter may help older adults support muscle protein and physical strength.
- Study participants demonstrated improved muscle performance without an increase in waist size.
- Other nuts, such as almonds, pistachios, hazelnuts, and Brazil nuts, also offer nutrients that support muscle health.
What the Source Says
A six-month study conducted by researchers at the Institute for Physical Activity and Nutrition at Australia's Deakin University examined adults between the ages of 66 and 89. Published in the Journal of Cachexia, Sarcopenia and Muscle, the findings indicated that individuals who consumed 43 grams of peanut butter daily showed increases in muscle power and muscle protein compared to a group that did not receive it. Participants in the peanut butter group were also able to complete a five-time sit-to-stand test faster, without expanding their waistlines.
Lead researcher Associate Professor Sze-Yen Tan explained that peanut butter naturally supplies key nutrients, including protein, healthy fats, and antioxidants. Research suggests these elements help limit inflammation and muscle breakdown. Additionally, peanut butter delivers vitamins and minerals such as magnesium and vitamin E, which are important for older adults.
For those who prefer not to eat peanut butter, other nuts provide similar benefits. Protein in almonds and pistachios helps fortify muscle, copper in hazelnuts assists with growth, and selenium found in Brazil nuts can also offer a muscle boost.
Practical Notes
Smooth peanut butter can be easier to manage and swallow than whole nuts, and it may be more cost-effective than purchasing over-the-counter dietary supplements. However, choosing the right product is essential. The study utilized store-bought, natural peanut butter containing minimal added sugar. Because some commercial varieties contain elevated levels of sodium or sugar, reading nutrition labels carefully is advised, particularly for individuals watching their dietary intake.
