Huge per nut: each one is about 33 calories and a full day of selenium. On the energy-density scale, 659 kcal per 100 g puts Brazil nuts at the very high end. Fiber is the standout at 7.5 g per 100 g, which slows a portion down more than the calorie count suggests.
A typical serving (1 nut, 5 g) has about 33 calories, and 100 g has 659 kcal. Calories scale with weight, so double the portion means double the number.
There are 14.3 g of protein in 100 g of Brazil nuts, which works out to about 0.7 g per serving (1 nut). Treat it as an energy source rather than a protein source.
Yes, in the plain arithmetic sense: 67.1 g of fat per 100 g supplies about 92% of the calories. Whether that fits your day depends on your totals, not on the food alone.
Every value on this page comes from USDA FoodData Central, entry 170569 (SR Legacy). Serving figures are converted from the per-100-g data, so rounding can shift a total by a calorie or two.
