Everything about NUTS!

For those of you who shy away from nuts due to fat content, take another look at the many health benefits of regular NUT consumption (in moderation, of course!) Let's crack the hard outer shell and get to the heart of these delicious and addictive treats. Here's everything you've ever wanted to know about nuts. Why we're nuts about NUTS Given the size of the average nut, it is amazing all the nutrients that can be packed into such as small package. Nuts such as almonds, walnuts, hazelnuts, macadamia nuts, pecans, pistachios and more... are a good source of protein, fibre, omega 3 and omega 9 fatty acids. They are also high in vitamin E, folate, calcium, magnesium and potassium. These nutritional properties make nuts a great choice for those looking for heart healthy foods, and those interested in both diabetes and cancer prevention. I love walnuts The polyunsaturated fatty acids in nuts have been shown to help lower blood cholesterol, as well as possessing anti-inflammatory properties. The phytosterol content inhibits accumulation of fat in the artery walls, decreasing risk of heart attack and stroke. Arginine, an amino acid found in a number of nuts is a precursor to nitric oxide, which acts to dilate blood vessels and help lower blood pressure. Calcium, magnesium and potassium also support healthy blood pressure. Nuts are high in antioxidants, helping to prevent free radical damage to heart cells. Folate can decrease homocysteine levels, helping to prevent stroke, heart attack and other cardiovascular events. There is no denying that our hearts beat for nuts. Reducing Cancer risk and more The coating or skin on many types of nuts is especially high in polyphenol antioxidants, which have been shown to reduce the risk of a number of cancers. Phytic acid, another anti-oxidant found in nuts has also been shown to decrease the incidence of colon cancer. The same phytosterols that that help to fight off stroke and heart attack, have also been shown to be powerful against both breast and prostate tumours. More recently, research is showing that the healthy fats in nuts may improve efficiency of insulin in the body, reducing the risks of developing Type II diabetes. No nuts for you! Despite all the pros of regular nut consumption (in moderation – I just had to say it again!), there are some individuals who would most likely benefit from avoiding them. There are certain foods that are more likely to cause a flare-up of Inflammatory Bowel diseases, like Crohns, Colitis and Diverticulitis, and nuts are one of these foods. Not all who suffer from these issues will find that they need to avoid nuts, but these individuals should always use caution when consuming nuts and be aware of any symptoms or exacerbation that can develop with their consumption. There is also some debate on how early nuts should be introduced into the diet. Especially when talking peanuts. Nuts tend to have a high allergenic potential, which at one time was a reason for delaying their introduction. Now, some research proposes that a delay is not necessary and may actually lead to a higher risk of allergy. The consensus seems to be that there is no consensus. Professionals say anytime between 12 and 36 months, nuts and nut butters can be introduced into the diet. Raw versus Roasted... the debate continues. When comparing nutritional information of raw versus roasted nuts, there is no denying that raw will always come out on top. That being said, these differences aren't as significant as some would believe and at the end of the day, dry roasted nuts still have nutritional value. The real difference between raw versus roasted nuts has very little to do with the protein, fibre or fat content of the nut itself, but rather the stability or shelf life, and perhaps equally as important is how the nuts are roasted – with or without oil, added salt, at what temperature, etc. The natural unsaturated oils on nuts, as good for us as they may be, are fragile and oxidize quickly when exposed to heat, light and air. Because of this roasted nuts tend to have a much shorter shelf live and can become rancid much faster than raw nuts. Storing all nuts in an airtight container either in the fridge or freezer can help to delay this process. Some nuts are roasted in oil, which most definitely adds to the fat content of the nut, and decreases nutritional value, as most times these oils are hydrogenated. Many roasted nuts are also salted, HEAVILY. Again this isn't great news for individuals looking to keep their salt intake to a minimum. Some nuts are also roasted at high temperatures. One rather alarming problem with this is that asparagine, an amino acid present in some nuts, specifically high in almonds, produces a by-product called acrylamide when processed or heated to high temperatures (above 120 degrees Celsius). In animal studies, acrylamide has been associated with an increased risk of developing several types of cancer and is considered a probable human carcinogen. One way to avoid aspargine exposure, as well as ensure there is no oil or salt added to your roasted nuts, is to simply roast them yourself. If you do this at a low temperature over a longer period of time, you still get the roasted flavour that many prefer, while maintaining as many nutrients as possible. Roasted nuts are also easier to digest than raw nuts, which may be good or bad depending on how you look at it. For individuals with compromised digestion to begin with, roasted nuts may prove an easier option. That being said, raw nuts that require a longer time and more energy to digest, can help to stabilize blood sugar and cause us to feel satiated for a longer period of time. This is one bonus for those eating nuts as a way to keep off or even help to lose a little extra weight. Freshness guaranteed Generally speaking nuts do have a season. They are usually harvested and at their most fresh and enjoyable in fall. Raw unshelled nuts have the longest shelf life and can be kept for up to one year if stored in a cool place. Even with raw nuts, once they are shelled, they are more prone to oxidization and becoming rancid. Again, be sure to store all unshelled nuts (roasted or raw) in an airtight container in the fridge or freezer. Take a look at the type of packaging and dates on all raw nuts, as well as the processing/roasting methods of all pre-packaged roasted nuts (look for added oils, sugars and preservatives- and avoid!). Use caution when buying nuts in bulk or from large bins, as it is hard know how long the nuts have been there and many of these containers are not airtight leaving their contents are more susceptible to oxidation. Peanuts are no nut at all. Few people realize that peanuts are actually not a nut or even a seed at all, but rather a legume and as such grow underground. Peanuts are rich in nutrients and contain about 25% protein, a little more than the average 'true nut'. That being said, there are some concerns about peanut consumption. Peanuts tend to be processed at even higher temperatures than other nuts. This is because peanuts are at a higher risk of being contaminated with the mold Aspergillus flavus, which produces a carcinogenic substance called aflatoxin. The high temperatures and processing methods may ensure these microorganisms are killed, but may also negate some of their nutritional properties. Peanut allergies are also quite common today, and many schools ban any peanut products from entering the schools, as even the smell of peanuts can cause anaphylactic shock in some individuals. It has been hypothesized that North American roasting techniques increase the allergen potential of peanuts by making specific allergens in peanuts more difficult to digest. If you'd prefer to avoid peanuts, but are still looking for something to compliment that honey or jam, think other nut butters, such as almond butter, cashew butter, hazelnut butter and more. Nut butters come in both raw and roasted varieties. Read the label so you know what you are getting. Almond butter is great served with quartered apples, or as an added protein in your morning smoothie. Give them a try! Moderation Despite all the many health benefits of the NUT, I must once again remind you that, as with most delicious treats, nuts should always be consumed in moderation. One serving of nuts depends on the nut in question. For instance, one serving of almonds is equal to about 24 almonds. One serving of pistachios contains about 47, while a serving of walnuts consists of roughly 14 walnut halves. Nuts may be high in many nutrients, but they also contain calories and fat, so be sure that you are taking some empty calories or refined carbohydrates out of your diet and substituting these protein, fibre and nutrient packed pieces in their place. Just always remember the rule of moderation. You can have too much of a good thing!
