They are similar in calories, so the portion, not the type, makes the difference.
Are nuts suitable as a protein source? Partly: 100 g contains about 15 g of protein, but also a lot of fat, so they are closer to a snack than a protein portion (see protein calculator).
Why are they sometimes bitter? The fats in nuts oxidize due to light and heat — so cool storage prolongs the flavor.
Can They Be Eaten Every Day? Yes, if the portion is small and fits within the daily energy requirement (see daily calories).
Are they suitable for people with nut allergies? No — nuts are a common allergen group, and hazelnuts belong to it.
