Chocolate hazelnut spread: half of the jar is sugar

The two ingredients on the label have trials behind them, and the spread has none that we found. In a meta-analysis of three randomized trials, adults who ate 1 to 2.4 oz (29 to 69 g) of whole hazelnuts a day for 4 to 12 weeks lowered LDL cholesterol by 5.8 mg/dL (0.150 mmol/L), with an interval from 0.308 down to 0.003 that only just clears zero. A meta-analysis of 31 randomized trials with 1986 adults found LDL fell 9.47 mg/dL (95% CI 5.20 to 13.75), and the product in those trials was cocoa extract or dark chocolate of at least 70 percent cocoa. What the jar reliably delivers is sugar. The US survey database lists 539 calories and 54.05 g of total sugars per 3.5 oz (100 g), from one averaged profile with no sample spread, and brands vary. A 20 g tablespoon, the amount the survey assumes for a slice of bread, works out at about 108 calories and 10.8 g of sugars when calculated from the 100 g figures. A sandwich amount of 40 g doubles that.

As people eat it, per 3.5 oz (100 g)

How much is actually in it

• Chocolate hazelnut spread in the US survey database carries 539 calories, 54.05 g total sugars and 29.73 g fat per 3.5 oz (100 g), so roughly half its weight is sugar. — USDA FNDDS survey food 'Chocolate hazelnut spread', food code 91304090 Evidence E source
  Per 100 g: 539 calories, total sugars 54.05 g, total fat 29.73 g

What a real portion looks like

• One tablespoon of chocolate hazelnut spread (20 g, the US guideline amount per slice of bread) gives about 108 calories and 10.8 g sugars, and a sandwich amount (40 g) doubles that. — USDA FNDDS survey food 'Chocolate hazelnut spread', food code 91304090 Evidence E source
  1 tbsp or 1 slice of bread (20 g): 107.8 calories, 10.8 g sugars, 5.9 g fat; sandwich (40 g): 215.6 calories, 21.6 g sugars, 11.9 g fat

What your body absorbs

• A systematic review found people get less energy from hazelnuts and other nuts than Atwater factors predict, and that available energy ranked nut butter above roasted and roasted above raw nuts. — 21 human and in vitro studies of tree nuts and peanuts, adults >=18 y (n = 21 studies) Evidence C source
  Metabolizable energy below Atwater prediction; ranking butter > roasted > raw, flour > chopped > whole

What cooking and storage change

• Clinical studies indicate roasting lowers hazelnut allergenicity in people with birch pollen allergy who react to raw hazelnut, and heat may reduce allergenicity of the PR-10 protein in vitro. — 32 clinical and in vitro studies of processed tree nuts (n = 32 studies) Evidence C source
  Roasting reduces allergenicity in birch pollen allergic people reacting to raw hazelnut; PR-10 allergenicity may fall with heat in vitro
• Laboratory data suggest acrylamide formed in roasting falls during storage, most in dry foods such as cocoa and nuts kept at 25 C or warmer. — processed foods analyzed during storage Evidence D source
  Acrylamide decreased in most matrices, largest drops in low-moisture products

What it does to your health

• In a meta-analysis of three randomized trials, diets with 1 to 2.4 oz (29 to 69 g) of whole hazelnuts a day for 4 to 12 weeks lowered LDL cholesterol by about 5.8 mg/dL (0.15 mmol/L), which says nothing direct about a sugar-based spread. — adults in hazelnut-enriched diet trials, 28-84 days, 29-69 g hazelnuts/day (n = 425) Evidence A source
  LDL pooled MD -5.8 mg/dL (-0.150 mmol/L) (95% HPD -0.308 to -0.003); total cholesterol -4.9 mg/dL (-0.127 mmol/L) (95% HPD -0.284 to 0.014); BMI no change
• A meta-analysis of 31 randomized trials found cocoa extract or dark chocolate of at least 70% cocoa for 4 weeks or more lowered LDL cholesterol by about 9.5 mg/dL, a cocoa dose that a milk chocolate spread does not provide. — adults with or without cardiometabolic conditions, cocoa extract or >=70% cocoa dark chocolate for >=4 weeks (n = 1986) Evidence A source
  LDL -9.47 mg/dL (95% CI -13.75 to -5.20); total cholesterol -8.35 mg/dL (95% CI -14.01 to -2.69)
• Observational data are too weak to say whether palm oil, a common fat in hazelnut spreads, raises or lowers heart disease risk. — adults in 5 included studies on palm oil and coronary heart disease or stroke (n = 5 studies) Evidence C source
  No pooled estimate; evidence graded very low

Safety, limits and interactions

• Across 36 prevalence studies, challenge-confirmed tree nut allergy was under 2% of people, though only seven studies used a food challenge. — 36 population prevalence studies, children and adults, 1996-2014 (n = 36 studies) Evidence C source
  Challenge-confirmed prevalence <2% (only 7 studies used challenge); probable 0.05-4.9%

What people believe that the data does not support

• In an RCT of 32 women with overweight, about 1.2 g of cocoa flavanols a day for 4 weeks did not improve fasting insulin sensitivity or insulin-mediated glucose uptake. — 32 premenopausal females, 19-49 years, BMI 27-35, HOMA-IR >1.5, 4 weeks (n = 32) Evidence B source
  No between-group difference in HOMA-IR or insulin-mediated glucose uptake
• The EU refused the claim that eating 1.1 oz (30 g) of nuts a day, hazelnuts included, helps maintain heart health. — EU health claim application for peanuts and tree nuts Evidence E source
  Status: non-authorized
• The EU did not authorize the claim that cocoa flavanols help maintain normal blood pressure. — EU health claim application for cocoa flavanols Evidence E source
  Status: non-authorized

Who this works differently for

• In 211 children undergoing 310 oral food challenges at one center, hazelnut was an independent predictor of a positive challenge, with an odds ratio of about 11. — 211 children (median 21 months), 310 oral food challenges, one tertiary center, 2023 (n = 211) Evidence C source
  Hazelnut OR 11.286 (95% CI 3.858-33.017) for positive challenge

The bottom line

Several things said about the ingredients have been checked and did not hold. In a randomized trial in 32 women with overweight, about 1.2 g of cocoa flavanols a day for 4 weeks did not improve insulin sensitivity, in a small, short study at a flavanol dose far above any spread. The EU refused a claim that 1.1 oz (30 g) of nuts a day, hazelnuts included, helps maintain heart health. It also refused a claim that cocoa flavanols help keep blood pressure normal. For palm oil, a systematic review of 5 studies graded all its evidence on heart disease and stroke as very low, so the honest answer there is that nobody knows. Nuts in general give the body less energy than label factors predict. A systematic review of 21 human and laboratory studies found that, and also found that available energy ranks nut butter above roasted nuts and roasted above raw. It pooled no numbers and tested no spread. The caution our cards cover is hazelnut allergy. Across 36 prevalence studies, tree nut allergy confirmed by a supervised food challenge was under 2 percent of people, though only seven of those studies used a challenge at all. In one hospital clinic in 2023, among 211 children with a median age of 21 months, a hazelnut challenge carried 11.3 times the odds of a reaction (95% CI 3.9 to 33.0), in a region where tree nuts are eaten often. Clinical studies show roasting lowers reactions in people with birch pollen allergy who react to raw hazelnut. That finding does not make a hazelnut spread safe for anyone with a hazelnut allergy. This is a milk chocolate spread, and we have no card listing its full ingredients or any allergen beyond hazelnut.

   The ME of nuts was consistently lower than that predicted by Atwater factors for investigated nut types (almonds, cashews, hazelnuts, pistachios, walnuts, and peanuts). The mechanisms may relate to a lower fat release from nuts, hence higher fecal fat excretion; however, this review did not consider the digestibility of carbohydrates and protein, which should be considered when interpreting the outcomes. ME was influenced by nut type (ME = 22.6 kJ/g for pistachios; ME = 18.5 kJ/g for raw almonds), physical form (flour > chopped > whole nuts), heat processing (butter > roasted > raw) and dose of consumption.
