What Is Peanut Butter, Anyway?
Peanut butter is a creamy or crunchy spread made by grinding roasted peanuts into a paste. In the United States, to be legally labeled as ‘peanut butter,’ at least 90% of its contents must be peanuts. Other simple ingredients include a small amount of salt, although many brands add sugar or oils for texture and flavor. Its widespread appeal comes from a winning combination of healthy fats, protein, fiber, and irresistible flavor.
Peanut Butter’s Origins: Who Really Invented It?
The origins of peanut butter marketing, mass production, and invention are often debated, but its roots can be traced to the ancient Incas and Aztecs, who ground roasted peanuts into paste. However, modern peanut butter’s story kicks off in the late 19th century:
- Marcellus Gilmore Edson patented a method for milling roasted peanuts between heated surfaces to create a paste in 1884.
- Dr. John Harvey Kellogg (of cereal fame) patented a process for making peanut butter from raw peanuts in 1895, marketing it as a health food for patients who couldn’t chew meat.
- Dr. Ambrose Straub invented a peanut butter-making machine and obtained a patent in 1903.
It was only a matter of time until peanut butter made its way into American kitchens and lunchboxes, where it rocketed to fame during the World Wars for its portability and nutritional power.
From Field to Jar: Growing Peanuts
- Peanuts aren’t true nuts—they are legumes (like beans and lentils) that grow underground, giving rise to nicknames like “groundnuts” and “ground peas.”
- The average peanut farm in the United States is about 200 acres.
- Each acre of peanuts can yield enough nuts to make around 35,000 peanut butter and jelly sandwiches.
- Approximately 540 peanuts are needed to make a single 12-ounce jar of peanut butter.
- Peanuts are surprisingly water-efficient: only 3.2 gallons of water are required to grow 1 ounce of peanuts, compared to almost 29 gallons for almonds.
Four Main Types of Peanuts
| Type | Key Characteristics | Popular Uses |
|---|---|---|
| Runner | Uniform size, high yields | Most commercial peanut butter |
| Virginia | Largest peanuts, crunchy | Snack nuts, gourmet |
| Spanish | Small, red skin, higher oil | Candy, old-fashioned PB |
| Valencia | Sweet, three or more kernels per shell | Boiled peanuts, specialty PB |
Peanut Butter Production: From Raw to Spreadable
The journey from field to jar involves harvesting, curing, roasting, removing skins, testing for quality, and finally grinding into paste. Roasting enhances both flavor and the antioxidant content of peanuts. The result? That smooth or chunky spread loved around the world.

The Health Benefits of Peanut Butter
- Protein Powerhouse: Packed with plant-based protein, peanut butter is an excellent way to boost daily protein intake, making it popular among athletes and vegetarians.
- Heart Health: Rich in monounsaturated and polyunsaturated fats—especially oleic acid—peanut butter helps maintain good cholesterol, blood sugar, and blood pressure, lowering heart disease risk.
- Antioxidants: Peanuts are a good source of vitamin E, resveratrol, B vitamins, magnesium, manganese, and potassium. Roasted peanuts contain even stronger antioxidants thanks to enhanced levels of compounds such as coumaric acid.
- Blood Sugar Control: Oleic acid and high fiber help reduce insulin resistance, lowering diabetes risk.
- Weight Management: The healthy fats, protein, and fiber in peanut butter are slow to digest, helping people feel full longer and potentially assisting with weight loss.
- Bone Health: Peanut butter contains copper, which may reduce the risk of osteoporosis.
Important Note: Choose natural peanut butter with minimal add-ons. Common commercial brands sometimes contain added sugars, hydrogenated oils, or excess salt, so for the greatest health benefits, look for those with only peanuts (and maybe a little salt).
