A few people are in here saying a pound or two a week is an unreasonable amount of peanut butter.
But when you buy peanut butter it comes in a 1-2 pound jar. If it’s your main source of protein, your favorite comfort food, or you have a poverty pantry, then I could totally see how you might think that one jar a week isn’t too bad.
Two pounds of peanut butter is about 6000 calories, or three days of energy for the average person. It shouldn’t be the main staple in your diet, as OPs doctor will attest, but it doesn’t seem strictly unreasonable.
I wonder how gourmet or homemade “nothing but peanut” butter compares to something like Kraft that’s loaded with sugar. Probably still not super great, but hey, maybe it’s better. Or maybe it’s worse. Eat a variety if you can.
With their high protein concentration, peanuts are used to help fight malnutrition. Plumpy Nut, MANA Nutrition,[67] and Medika Mamba[68] are high-protein, high-energy, and high-nutrient peanut-based pastes developed to be used as a therapeutic food to aid in famine relief. The World Health Organization, UNICEF, Project Peanut Butter, and Doctors Without Borders have used these products to help save malnourished children in developing countries.
A 200Lb adult needs a minimum of 140g of protein daily to remain healthy.
The standard recommendation is about 0.8g per kilogram of body weight. So 200 lbs is 91 kg, which corresponds with 73g.
There’s some more recent advocacy for more protein, especially for active or older people, but that’s talking about more than just the minimum requirements to be healthy, and more towards optimizing for performance.
This issue can occur when eating one food excessively for long periods. I distinctly recall this being covered in pre- college health classes.
A common urban legend was the girl who only ate carrots and turned orange.
the girl who only ate carrots and turned orange.
I can confirm this is a real thing. When I was a kid my step-mother went on this fad diet that involved drinking carrot juice every day. It was this whole production where she bought a juicer and I remember multiple large bags of carrots coming in the house. There was always leftover carrot pulp in the trash, etc. Anyways she went wild with it for a time and sure enough her skin started turning slightly orange, mostly along her forearms where the skin was thin.
That’s when the carrot juice stopped.
So yeah she wasn’t an Oompa Loompa but it was definitely a visible change.
A friend of mine spoke to this man on a train ride. He lived in the town we went to college in.
Eating peanuts or peanut butter for protein is weird because it’s wayyyy higher in fat. Don’t eat it for protein, it’s a fat source really.
I agree, but at least nuts are high in unsaturated fats, which have some rather solid clinical backing as being healthy. Obviously still energy-dense, and if nuts are used a primary protein source it will likely be difficult to stay within a restricted caloric budget.
E.g. if you want to follow the government recommendation and have 20% of your calories come from protein, peanuts will fall short as only 18% of their calories are sourced from protein (79% from fat). 349 grams of peanuts (about 3/4 of a pound) has 2000 calories and 91 grams of protein - with 175 grams of fat.
I’ve always heard that peanuts were kind of the last option you’d want to pick among nuts, specifically because they’re so high in saturated fats (about 20% of the fat content). They’re not bad per se, but there are much better options.
Still, they’re a great source of added protein and unsaturated fats, but like you said, don’t rely on them as your primary source.
Y’know, that’s an interesting point.
I blame our nutritional education. I grew up with the Food Pyramid (now debunked), and peanut butter would be considered a “meat alternative” which I think people conflate with being a source of protein.
That’s not how it was taught. Maybe that’s how you learned it. Peanut butter and peanuts were on the bottom row with vegetables, not a meat sub.
