Seven More Peanut Butter Facts

Peanut butter more or less as we know it today was popularized at the 1893 World Fair. In the early 1900s, peanut butter made frequent appearances in tea rooms across the nation where it was billed as a dish for rich people. Back then, it was paired with items, such as cucumbers, cheese, celery, and crackers. At that point, peanut butter was still considered a “high end” food and peanut butter and jelly sandwiches were not a commonly eaten food item.

Peanut butter spread to the masses during the 1920s and 1930s, shortly after pre-sliced bread came into existence. At that time commercial brands Skippy and Peter Pan began.

With the Great Depression, peanut butter on bread became a staple in many American households, because it provided a hearty, filling meal with a cheaper-than-meat substitute for protein.

During WWII the peanut butter and jelly sandwich became a popular meal among United States soldiers. When soldiers arrived home from the war, peanut butter and jelly sales skyrocketed.

The PB&J is a bigger hit in the United States than in most other countries.

The average American will eat around 1,500 peanut butter and jelly sandwiches by the time they turn 18.

Incidentally, peanuts are not nuts, they are legumes (a type of plant with seeds that grow inside pods like peas or beans). Nuts are grown on trees, peanuts grow underground. March is National Peanut Month.

Nuts to Food Allergies

Food allergies are less common in underdeveloped countries. Proponents of the hygiene hypothesis say that the relatively low incidence of childhood infections in developed countries contributes to an increased incidence of allergic diseases.

Harvard Medical School asserts that recent increases in peanut allergies, and the measures taken in response, show elements of mass psychogenic illness - hysterical reactions grossly out of proportion to the level of danger.

Only 150 people (children and adults) die each year in the US from all food allergies combined. The US Centers for Disease Control and Prevention officially documents 13 deaths (including six adults) due to peanuts between 1996 and 2006. Peanuts are legumes, not true nuts.

Four percent of adults and four percent of children have food allergies. Less than one percent (0.6) of people in the US have a peanut allergy. In France, the rate of peanut allergy is between .3 percent and .75 percent, Denmark is .2 to .4 percent; and Israel about .04 percent.

The exact cause of someone developing a peanut allergy is unknown.

Smelling the aroma of peanuts cannot cause an allergic reaction.

Highly refined peanut oil is purified, refined, bleached, and deodorized, which removes the allergic proteins from the oil.

A recent study showed 26.6% of children with a peanut or tree nut allergy outgrew their allergies, at an average age of 5.4 years old. Black children were less likely to outgrow their allergy than white children and boys were more likely to outgrow their allergy than girls.

The American Academy of Pediatrics used to instruct parents to avoid peanut use until their kids reached age 3, but that has been rescinded. A British study has found that consuming peanuts in infancy lowers the risk that a child will develop peanut allergies.

Headlines most often ignore that people who are allergic to peanuts are also often allergic to one or more tree nuts (almonds, walnuts, pecans, cashews, pistachios, etc.).

A new study shows increased peanut consumption by pregnant mothers who were not nut allergic was associated with lower risk of peanut allergy in their offspring.

Peanuts and Almonds are not Nuts

Notwithstanding the above, peanuts are not nuts. They are legumes. The plant has seeds that grow inside pods such as peas or beans. Nuts grow on trees, peanuts grow underground. Peanut seeds flower above ground and then migrate underground to reach maturity. Peanuts are also called goobers, goober peas, groundnuts, earthnuts, monkey nuts, and grass nuts.

Also, almonds are not nuts. An almond is the seed of the fruit of the almond tree. The tree bears fruits with a seed within. Fruits with these characteristics are called drupes. A drupe is a fruit that has an outer fleshy part surrounding a shell that contains a seed. Other drupes include fruits from walnut trees and coconut trees. The seed inside the almond fruit is called an almond nut, even though it is not a nut. A nut is a hard shelled fruit that doesn't open to release its seed.
