We’ve looked at almonds and walnuts before now for their heart health benefits, but pistachios too are receiving some positive press as well. They are not only full of flavour and interesting and fun to eat but also healthy.
The pistachio is a fruit but to us an edible seed of the Pistacia vera tree. They are generally a very good source of fats, protein, fiber and assorted antioxidants.
Pistachios also turn up as an attractive addition in processed meats. A mortadella sausage which comes from Bologna is not easily recognisable unless it is flecked with these green tinged slices of nut within the mix. Clearly its not going to add to the health benefits of what is a defined fatty sausage but it does provide additional glamour to this famous large sausage.

Weight Loss And Dieting
Some people think that snacking on lots of nuts is not good for us and will ultimately lead to us putting on lots of weight and producing adverse triglyceride profiles. However, some nuts are great for snacking with such as pistachios.
In one study which covered a 12-week weight loss program, it was found that eating 53 grams (1.9 ounces) of pistachios per day as part of a snacking treat was better for you than the equivalent weight of pretzels which represented a carbohydrate snack. It seems those eating the pistachios enjoyed twice the reduction in their body mass index (BMI) compared to those eating the pretzels (Li et al., 2010).
Heart Health And Pistachios
One study showed that after eating pistachios, LDL cholesterol levels dropped. This was revealed in a crossover feeding study although not a huge number of subjects took part. Sixteen people ate pistachios for three weeks as part of a controlled diet. Three levels of pistachio consumption were selected, none at all, 42 and 84 g/day. The level of LDL cholesterol lowered was 6% with the highest level of consumption but there were no statistically significant changes to the blood levels of plasma total cholesterol, HDL cholesterol or the triacylglycerol content (Baer et al., 2012).
