Calories in Nuts, almonds, dry roasted

What makes nuts so powerful?

Almonds aren't true botanical nuts; they are the seeds of the Prunus dulcis fruit, making them closer relatives to peaches and cherries. Wild almonds contain amygdalin, which breaks down into deadly cyanide, but ancient farmers in the Levant selectively bred for sweet mutations lacking this compound. Dry roasting these sweet almonds further neutralizes trace bitterness and enhances their texture, making them brittle and crunchy by driving off internal moisture. The heat triggers the Maillard reaction between amino acids and reducing sugars, creating hundreds of new flavor compounds that give roasted almonds their characteristic toasted profile. However, this thermal processing comes at a nutritional cost. While the breakdown of cell walls can make certain minerals easier to absorb, the heat degrades heat-sensitive tocopherols like vitamin E. Furthermore, the newly exposed fats oxidize faster, meaning roasted almonds have a shorter shelf life than raw almonds and require airtight, cool storage to prevent rancidity.
