Almonds vs cashew nuts: carbs, fiber and net carbs
Full comparison · Protein · Calories · Carbs · Healthier
Per 3.5 oz (100 g), almonds has 20 g of carbohydrate (9.3 g net) and cashew nuts has 36.3 g (32.2 g net).
Net carbs = total carbohydrate minus fiber.
| Almonds | Cashew nuts | |
|---|---|---|
| Total carbohydrate, 100 g | 20 g | 36.3 g |
| Fiber, 100 g | 10.8 g | 4.1 g |
| Net carbs, 100 g | 9.3 g | 32.2 g |
| Total sugars, 100 g | — | — |
| Carbs per serving | 5.7 g in 1 oz (28 g) | 10.3 g in 1 oz (28 g) |
| Net carbs per serving | 2.6 g | 9.1 g |
Net carbs is total carbohydrate minus fiber; it is a common counting convention, not an FDA label term. Total sugars include natural and added sugar; USDA does not separate them for these foods.
What the numbers don't tell you
Raw, cashews have a few fewer calories, 533 against 584 per 3.5 oz (100 g), and almonds more fiber and protein. The bigger gap is in the evidence. Across 36 publications with 2,485 adults, almonds lowered LDL cholesterol by about 5 mg/dL (0.13 mmol/L), a small drop. For cashews, three pooled trials showed no clear change, and 42 g a day for four weeks moved no main heart risk factor. With so few trials, the cashew answer is unclear more than negative.
Labels overstate both. A 1 oz (28 g) serving of cashews delivered 137 calories in a feeding study, 16 percent below the label, and whole raw almonds release less energy than roasted almonds or almond flour.
In the few studies that confirmed it by food challenge, tree nut allergy affected under 2 percent of people. Most lab studies find the allergy-linked proteins of cashew and almond stable through heat processing, so roasting should not be counted on to remove them. Among children allergic to cashew, an estimated 5 percent react to 7.4 mg of its protein. In one man who already had chronic kidney disease, 3 to 4 oz (85 to 113 g) of cashews a day for a year preceded oxalate kidney damage.
If cholesterol is your reason, almonds have the trials. Otherwise eat the one you enjoy.
Evidence behind this note
- Level A A 2025 meta-analysis of randomized trials with 2,485 adults found almonds lowered LDL cholesterol by 0.13 mmol/L (about 5 mg/dL) versus nut-free control. Nutrients, 2025
- Level A Pooled across three randomized trials of cashew supplementation, LDL cholesterol moved by a standardized mean difference of -0.18 (95% CI -0.75 to 0.39), which includes no effect. Complement Med Res, 2020
- Level B Feeding 1.5 oz (42 g) of cashews a day for 4 weeks under full dietary control changed none of the primary cardiovascular risk factors in 42 weight-stable adults. Am J Clin Nutr, 2019
- Level B A 0.99 oz (28 g) serving of cashews delivers 137 calories on average, which is 16% less than the figure printed on food labels. Nutrients, 2018
- Level C Whole raw almonds give up the fewest calories, and grinding or roasting them hands over more. Adv Nutr, 2023
- Level C A systematic review found challenge-confirmed tree nut allergy affects under 2% of people. Curr Allergy Asthma Rep, 2015
- Level D Roasting does not disarm the cashew allergen: the seed storage proteins that cause cashew reactions stay heat stable across thermal processing methods. Allergy, 2013
- Level C Among children allergic to cashew, 5% react with objective symptoms to as little as 7.4 mg of cashew protein. J Allergy Clin Immunol, 2013
- Level D A year of eating 3 to 4 ounces of cashews daily preceded oxalate nephropathy, confirmed on kidney biopsy, in a 78-year-old man whose creatinine rose from 2.05 to 6.0 mg/dL. Kidney Med, 2026
