As you can imagine, we had lots of peanut butter in our house.
You can also probably imagine my disappointment when I heard that peanut butter may not be so good for you, after all. While peanuts are a decent source of plant-based protein, they are also highly susceptible to mold that produces aflatoxin– a carcinogen that has been associated with liver cancer (1), stunted growth in children (2), and mental retardation (3). On a positive note, research has shown that the aflatoxins may be reduced by as much as 89% when the peanuts are processed into peanut butter (4). Another issue with peanuts is that they are high in Omega-6 fatty acids, which have been associated with an increased risk of inflammation and cardiovascular disease (5). Omega-3 fatty acids have been shown to help reduce this inflammation and risk of chronic disease, but Western diets tend to contain far too many Omega-6 fatty acids already (6), making peanut butter a poor choice for balancing out this ratio. To add insult to injury, peanuts also contain lectins, which may promote cancer growth (7), and conventionally grown peanuts are highly exposed to pesticides– so buying organic is a must in this case. Peanut butter also tends to be a highly addictive food for many people, which can be a sign of intolerance, so if you find yourself unable to stop at a reasonable serving of peanut butter, you may want to try eliminating it for a period of time to see if it’s affecting you more than you realize. —
So, knowing what I do now, why do I still make treats that include peanut butter? There are a couple of reasons: The studies aren’t all bad when it comes to peanuts and peanut butter, either. One human study showed that adding peanut butter to the diet actually reduced triglycerides in the blood (8), and a Nurses’ Health Study showed that women who regularly ate peanut butter had a lower risk of developing Type 2 diabetes (9). — Of course, if you’d prefer to steer clear of peanut butter all together, there are plenty of alternatives available. I’m partial to almond butter in most cases, but sunflower butter is a great nut-free option, too! Reader Feedback: How do you feel about peanut butter? Does it still have a place in your home?
