Peanut spread: a label rule, and what peanut research says

The firmest finding that applies here is about peanuts in general. By a meta-analysis of 3 randomized trials in 4183 infants, introducing peanut foods before 12 months of age cut the risk of peanut allergy by about two thirds (RR 0.31, 95% CI 0.17 to 0.54). The trials used different forms of peanut, and none of them tested a spread by name, so this page does not say how or in what form to give peanut to an infant. For a baby who already has eczema or another food allergy, the first peanut is a question for the child's doctor before anything is tried at home. Peanut spread itself is a legal category in the United States. A spreadable peanut product with more than 10 percent non-peanut ingredients must be called peanut spread and must state its percentage of peanuts. If it is nutritionally inferior to peanut butter, it must be labeled an imitation, and equivalence on protein starts at 24 percent. We found no study of peanut spread as a product, so every health finding below comes from peanuts and peanut butter.

The numbers, per 3.5 oz (100 g)

How much is actually in it

• Under US rules, a peanut product with more than 10 percent non-peanut ingredients must be called peanut spread and state its percentage of peanuts. — Spreadable peanut products sold in the United States Evidence E source
  Name peanut spread plus peanut percentage in 5 percent steps
• Under US rules, a peanut spread that is nutritionally inferior to peanut butter must be labeled an imitation, and equivalence starts at 24 percent protein. — Spreadable peanut products sold in the United States Evidence E source
  Protein at least 24% with quality at least 68% of casein, or at least 16.6% with quality equal to casein
• Reduced sugar peanut spread in US data carries 54.9 g fat, 16.4 mg niacin and 0.76 mg copper per 3.5 oz (100 g). — USDA SR Legacy Peanut spread, reduced sugar (FDC 172457) (n = 1 record) Evidence E source
  Fat 54.89 g, niacin 16.385 mg (102% DV), copper 0.76 mg (84% DV) per 3.5 oz (100 g)

What a real portion looks like

• In the US survey database, one tablespoon of peanut butter and chocolate spread weighs 16 g and a sandwich takes 32 g. — USDA FNDDS Peanut butter and chocolate spread (42203100) (n = 4 measures) Evidence E source
  1 tablespoon 16 g, per slice of bread 16 g, per sandwich 32 g, quantity not specified 32 g

What your body absorbs

• In 137 Indian women, adding nuts including peanuts to bread cut iron absorption from 6.6 to 1.8 percent. — 137 Indian women eating bread meals with or without walnuts, almonds, peanuts or hazelnuts (n = 137) Evidence C source
  Geometric mean iron absorption 1.8% with nut meals versus 6.6% with bread alone

What cooking and storage change

• A systematic review of 21 human and lab studies found that nuts and peanuts yield less energy than labels predict, and nut butter releases more than roasted or raw nuts. — Human feeding studies in adults and in vitro digestion studies of tree nuts and peanuts (n = 21 studies) Evidence C source
  Metabolizable energy lower than Atwater factors; order by processing butter > roasted > raw
• Laboratory data pooled from 19 processing trials, mostly on peanuts, suggest roasting reduces aflatoxin B1 by about 47 percent. — Nut samples, mostly peanuts, in roasting, irradiation and fumigation experiments (n = 19 trials) Evidence D source
  Roasting: aflatoxin B1 -46.91%, B2 -30.66%, G1 -40.88%, G2 -26.19%

What it does to your health

• In a 12-week crossover trial in 61 older adults, eating peanuts raised energy intake by 853 kJ a day yet body weight rose only 1.1 lb (0.5 kg), less than predicted. — 61 healthy adults, mean age 65 years, BMI 31, high oleic peanuts at 15 to 20% of energy for 12 weeks (n = 61) Evidence B source
  Energy intake +853 kJ/day (+10%); weight +1.1 lb (0.5 kg), less than predicted; no change in lipids, CRP, glucose, insulin

What people believe that the data does not support

• The EU did not authorize the claim that two tablespoons of peanut butter a day help achieve healthy cholesterol levels. — EU health claim application for peanuts, peanut butter and peanut oil Evidence E source
  Non-authorized

Who this works differently for

• By a meta-analysis of 3 randomized trials in 4183 infants, early introduction of peanut foods cut the risk of peanut allergy by about two thirds (RR 0.31). — Infants in randomized trials introducing allergenic foods before 12 months of age (n = 4183) Evidence A source
  Peanut allergy RR 0.31 (95% CI 0.17 to 0.54), high to moderate certainty
• Observational data pooled from 190 studies link introducing peanut after 12 months of age with higher odds of childhood food allergy (OR 2.55). — Children under 6 years in cohort, case-control and cross-sectional studies, 2.8 million participants, 40 countries (n = 2.8 million) Evidence C source
  Peanut after 12 months OR 2.55, risk difference 6.8% (95% CI 1.9% to 14.6%)
• The CDC lists chunks or spoonfuls of nut butters such as peanut butter among potential choking hazards for young children. — Infants and young children (n = -) Evidence E source
  Listed as food to avoid for young children (choking risk)

The bottom line

The only US composition record is a reduced sugar peanut spread. It carries 54.9 g fat, 16.4 mg niacin and 0.76 mg copper per 3.5 oz (100 g), from a single record with no range of values. The survey database has no plain peanut spread at all. Its nearest entry, a peanut butter and chocolate spread, puts one tablespoon at 16 g and a sandwich at 32 g. A systematic review of 21 human and laboratory studies found that nuts and peanuts yield less energy than label factors predict, and that nut butter releases more energy than roasted or raw nuts. The review had no pooled analysis and its methods varied. In a 12-week randomized crossover trial in 61 adults with a mean age of 65 and mean BMI of 31, whole high oleic peanuts raised energy intake by 853 kJ a day. Body weight rose 1.1 lb (0.5 kg), less than predicted, and blood lipids, CRP, glucose and insulin did not change. Those were whole peanuts. The authors offer incomplete absorption only as a possible reason. In a 1988 non-randomized study of 137 Indian women, bread meals with walnuts, almonds, peanuts or hazelnuts gave 1.8 percent iron absorption against 6.6 percent from bread alone. The nuts were mixed, so the figure is not specific to peanuts. The EU did not authorize the claim that two tablespoons of peanut butter a day help achieve healthy cholesterol levels. The register gives no reason, and a refused claim is not proof that there is no effect. Who should be careful. Peanut allergy is the caution on this page, and the infant trials above are the strongest evidence here. Observational data pooled from 190 studies in 2.8 million children under 6 link introducing peanut after 12 months of age with higher odds of childhood food allergy (OR 2.55). Those are odds from observational studies, and the form of peanut was not recorded. Laboratory data pooled from 19 processing trials, mostly on peanuts, suggest roasting lowers aflatoxin B1, a mold toxin, by about 47 percent, which also means roasting does not remove it completely. We found no study of interactions between peanut spread and medicines. We also hold no card on how a thick spoonful of spread or whole peanuts suit a baby or young child learning to swallow. The tablespoon and sandwich sizes above are adult portions, and the form for a child is a question for the child's doctor.
