Pistachios are heavenly nuts, and according to our ancestors, everything from heaven is colorful. So as pistachios are. Do you recall red pistachios? The tale is incredible! 
How about pistachios dyed green? That is also fascinating! I fell in love after eating so many pistachios that my fingers were completely red! And yes, I am aware of your thoughts. There is nothing harmful about these lovely beauties. Let's see whether I am correct. 
WHY WERE PISTACHIOS DYED RED
Don't forget red pistachios! Before the 1970s, it was almost hard to locate pistachios that did not leave a scorching red powder on one's fingers. What then becomes of red pistachios? And from whence did they first originate? Find out further below. Two contradictory explanations exist about why pistachio shells were formerly red. According to one account, a pistachio salesman called Zaloom in Brooklyn, New York, at the beginning of the 20th century was the originator of the color red. To distinguish his wares from the competitors, he chose to color his nuts. According to the legend, Zaloom's dyeing technique became the norm for pistachios in the United States shortly after its introduction. So Why Were RED Dyers At All? A research shows that the red coloring of pistachios was used to hide the nuts' natural but unattractive characteristics. Before distributing the nuts, which were mostly imported from Iran, American processors would color them with a dyed tool. The artificial red coloring gives red pistachios their distinctive hue. The red coloring may leave a dramatic mark, but it has no impact on the taste. Without the added color, the pistachios that we all consume now lack no additional taste. Red pistachios are difficult to locate on supermarket shelves since the majority of pistachios are uncolored. However, you can still get red pistachios online if you find yourself yearning for a helping of vividly-colored reminiscence. 
RED PISTACHIOS CANCER
I will never be able to forget the times when people made snarky comments about red pistachios since they were so prevalent in the market. Both positive and negative phrases, but with an acknowledged mistake here and there. I seem to remember that each individual pistachio had a warning about the risk of developing cancer. Nevertheless, there is some evidence that it inhibits the growth of cancer! The relationship between eating pistachios and the risk of developing breast cancer Although there is some evidence that a greater intake of tree nuts is associated with a lower risk of developing breast cancer, in particular, estrogen receptor-negative (ER-), breast cancer, not all research has reached the same conclusion. Pistachio consumption and a higher risk of breast cancer are not strongly linked, according to available research. Pistachio kernel extracts, in a dose- and time-dependent manner were shown to reduce the viability of hormone receptor-positive (ER+/PR+) breast cancer cells, as indicated by a study that was published in 2018. It has been shown that a high intake of dietary fiber and vitamin E (but not vitamin E pills) is related to a decreased risk of breast cancer. However, vitamin E tablets do not seem to have the same effect. 
IS THE RED DYE ON PISTACHIOS HARMFUL
In my opinion, you'll be able to express it precisely after you've read the narrative. There are so many variables, so I'll leave it to you to decide if it's harmful or not. The elimination of red-colored pistachios is a direct consequence of the meteoric rise in the production of pistachios domestically as well as the reduction in the number of pistachios imported from Middle Eastern countries. According to the Kitchn, in the past when the United States imported pistachios, the shells of the nuts would often have a mottled or speckled appearance. The ancient methods of harvesting resulted in the nuts not being hulled and cleaned as soon as they were collected, which caused the shells to become discolored. Richard Matoian, Executive Director of the American Pistachio Growers, told HuffPost Taste that pistachio growers in the Middle East began dyeing the shells a vibrant red in order to conceal the stains since the sight of these stains was unappealing. According to Matoian, a few American manufacturers followed suit since the market was accustomed to seeing pistachios with a brilliant red tint. But there's no need to worry about all of it now. According to Matoian, the decade of the 1980s marked the beginning of the decline of red pistachios. It is no longer necessary to color the nuts as a result of restrictions placed on imports, which led to an increase in the production of nuts in the United States, which led to the development of American harvesting techniques. Pistachio growers in the United States utilize a harvesting method that dries and hulls the nuts before the nuts have a chance to get discolored, which removes the need for concealing any defects at all. Matoian noted that even now in Iran, pistachio farmers have adopted a new harvesting method that does away with stains and, as a result, the need for coloring. 
GREEN DYED PISTACHIOS
Why are pistachios colored green? Have you ever wondered why the inside of pistachio resembles an avocado more than an almond? According to the American Pistachio Growers, carotenoids are responsible for the green color of pistachios' interiors. If you believe that this term resembles "beta-carotene," the fat-soluble pigment that gives carrots their vibrant orange color, you are correct. Similar to beta-carotene, lutein and zeaxanthin are carotenoids—antioxidant plant pigments that exist naturally. These carotenoids, together with chlorophyll, give the nut its yellow and green colors. In addition, the red and purple hues on the exterior of pistachios are a result of the antioxidants resveratrol and anthocyanins. Are pistachios a source of fat? Not really! is the brief response. Even while each 100-gram meal contains 45 grams of fat, over 90 percent of the fat is mono- and polyunsaturated. 
Liz Shaw, a registered dietitian who consults for Wonderful Pistachios, told RealSimple.com via e-mail, I believe many individuals are still on the fat-phobic train in which they equate any form of nutritional truth with a fear of 'becoming fat. I am always advising people to disregard their overall body fat percentage and instead concentrate on nourishing their bodies with heart-healthy unsaturated fats. Pistachios are sometimes referred to as "the slim nut" since they have the fewest calories per ounce of any tree nut. As a healthy snack, you may have 49 nuts, which is the recommended serving size, and at three calories per nut, you will only ingest 147 calories. Do pistachios contain gluten? Yes, pistachios do not contain gluten since they are nuts and not cereal grains. Check the box if you are gluten-allergic or gluten-sensitive, since certain pistachios may be combined with spices or other substances that do contain gluten. 
RED PISTACHIOS FOR SALE
Once upon a time, people laughed at the question "Where can I acquire red pistachios?" because they thought it was ridiculous. After all, they were freely available, having been imported mostly from Iran, which used the hue to disguise unpleasant harvest stains. In Iran, the color was employed to conceal unattractive harvest stains. Since 1979, when relations between the United States and Iran began to deteriorate, there has been no longer any need for dye. However, a renewed interest in red pistachio nuts has led to an increase in demand for these nuts, and as a result, Oh! Nuts is once again offering salted and roasted red pistachios. Pistachios have always been highly regarded for their taste, but their nutritional significance is often disregarded by consumers. On the other hand, they are of great assistance. There is more fiber in one dish than there is in half a cup of either broccoli or spinach. Therefore, buy from Oh! Nuts in bulk if you want a great party novelty and to ensure that you have enough to take with you when you leave. 
RED PISTACHIO FINGERS
An excellent medicine is a nostalgia. For those of us who are old enough to remember, red pistachios played a significant role in our childhood recollections. People contacted their buddies on landline phones and ate pistachios that stained their fingers crimson. As children, we never questioned the hue of this particular side effect of eating a nut (which is really cashew) that caused us to become green. Now, on National Pistachio Day, February 26, it's time to explore this relic of the past and address two pressing questions: Why were pistachios colored red in the first place, and why aren't red pistachios available anymore?! It all began with a Syrian pistachio importer named Zaloom, who allegedly painted his pistachios red to distinguish his product from that of his rivals and to conceal any small harvesting flaws. Back up a little. It is claimed that the pistachio is native to the Middle East, notably Iran, and was extensively farmed from Afghanistan to the Mediterranean area, as well as in California. While Persian chef and author Najmieh Batmanglij say Iranians do not intentionally color their pistachios (the dyed pistachios likely originated in Syria and found their way to the United States), the nuts are essential to Middle Eastern culture. "Pistachios play a major part in the culture and cuisine of both Iran and Turkey," explains Najmieh. "For them, pistachios are daily snacks; they are roasted, salted, and sometimes served with lime juice." There are pistachio biscuits that are flavored with rose water and cardamom, pistachios with lamb that have been braised with rose water and saffron, and pistachio meatballs that have been cooked in pomegranate juice, etc.
