Yes, pistachios are worth it, especially since the producers manufactured them because they put a lot of time, effort and resources into producing every piece of pistachios. Despite the high price, these nuts are worth buying. But of course, if you don't like to spend a lot of money, you can always opt for other alternatives. My materials were an eight-ounce bag of pistachios with shell and a six-ounce bag of the unshelled variety, purchased at my local supermarket.
Pistachios may reduce the risk of some types of cancer, such as colon cancer, due to their high fiber content. A one-ounce serving of pistachios equals 49 nuts, more nuts per serving than any other nut and contains more than 10% of the daily value of dietary fiber, vitamin B-6, thiamine, phosphorus and copper. Researchers found that a group of overweight or obese people who ate a serving of pistachios every day had a lower body mass index and waist circumference than those who didn't eat pistachios. Pistachios are especially rich in phytosterols, which are directly related to the reduction of cholesterol levels and may offer protection against certain types of cancer.
In addition, pistachios have a relatively high content of a non-essential amino acid, arginine, which may play a potential role in preventing or reducing cardiovascular disease. But the reason why is this not the case for pistachios? Between 70 and 90 percent of pistachios develop a natural indentation in their shells during the cultivation process, says Louise Ferguson, a pistachio expert at the University of California, Davis, co-author of the Pistachio Production Manual. In addition, pistachio producers must rotate their crops, since they only produce a yield during alternate years. Pistachios are a very high quality vegetable source of protein, since they provide adequate and balanced amounts of essential amino acids.
But if you look at the prices charged by retailers, shelled pistachios tend to be more than twice as expensive per ounce as those with shells, so all you save is the trouble of extracting them and paying a substantial fee for that luxury. Whitehouse went to Iran and returned with 9 kilograms (20 pounds) of walnuts that he used to grow pistachios. Pistachios have a low glycemic index, so they don't cause a sharp rise in blood sugar after someone has eaten them. Pistachios had the most significant effect of all the nuts tested in reducing systolic and diastolic blood pressure.
