About Rika Susan
Expertise
My main interest is in juicing fruits and vegetables for health. I specialize in all aspects of juicing, juicers and the preparation of fruits and vegetables for juicing. General healthy nutrition and dieting also form part of my experience.

Experience
I have been using juicing as an integral part of my family's diet and nutrition program for almost 15 years. I have developed a passion for juicing as an easy way of gaining access to the required daily portion of fresh fruits and vegetables - especially where parents are struggling with kids who won't eat veggies. Some years ago I began writing about juicing and I developed a website http://www.best-juicing.com/.

Education/Credentials
I don't have specific credentials in this area, apart from years of experience and research.

Nutrition & Dieting - Calories in Pistachio nuts

Expert: Rika Susan - 10/26/2009

Question
Hi,

I've read that pistachio nuts have 700 calories per cup.

What is never specified is whether this means a cup of pistachios in shells or a cup of pistachios that have been shelled.

Since a pistachio in the shell takes up much more space than a shelled pistachio, the difference is crucial. If a cup of pistachios in the shells have 700 calories, they are very fattening. If what is referred to is the pistachios without the shells, then pistachios are not very fattening (since a cup of such pistachios would be more than anyone would eat).

Many thanks,

Steve

Answer
Hi Steve

Thanks for your question. You are absolutely correct that the difference is crucial. I think I have some good news for you! As far as I know, a cup of pistachio nuts in shells has only about 330 calories, while shelled pistachio nuts are in the region of 728 calories per cup. So, they are not that bad in terms of being fattening. But all nuts are quite high in calories and fat content, so it is just sensible to be aware of this - as you obviously are.

Just to add extra interest: Research has shown that it is always better to opt for the version that takes a bit more work. In other words, if you go for pistachios in the shell, you are likely to consume less than if you choose them shelled. The same is true for peanuts, for example. There can be a variety of reasons for this, such as the in-shell option creating the perception that you are eating a larger portion, or it can be because you will be eating them at a much slower rate. If you are watching your calorie intake, it is almost always better to go for foods that takes more time to eat and that requires lots of chewing.

Happy shelling!
Rika Susan
