Can Eating Nuts Help You Lower Risk of Heart Disease? Part 2

Consumption of nuts lessens your possibility of developing blood clots that capable of cause a fatal heart attack. Nuts also improve the health of the lining of your arteries. The facts for the heart-health benefits of nuts aren't rock-solid yet the Food and Drug Administration only allows food companies to say proof "suggests but does not prove" that eating nuts lessen heart disease risk. Still, the obtainable evidence looks promising.

It's entirely unclear, but it's thought that the unsaturated fats in nuts both monounsaturated and polyunsaturated fats lower bad cholesterol levels. Many nuts are also rich in omega-3 fatty acids. In preventing unsafe heart rhythms that can lead to heart attacks Omega-3s are a healthy form of fatty acids that appear to help you heart among other things. Omega-3 fatty acids are also found in fish, but nuts are one of the premium plant-based sources of omega-3 fatty acids. Nuts also have lots of argentine, which is a molecule that amplify the production of nitric oxide in your body, which may in turn help improve the health of your artery walls and make them more flexible and less prone to blood clots. Other substances in nuts that could improve your heart health include Vitamin E and fiber.

Generally nuts become the most visible good food for your health. Walnuts are one of the best-studied nuts, and it's been exposed they contain high amount of omega-3 fatty acids. Almonds, macadamia nuts, hazelnuts and pecans are other nuts that show to be heart healthy. Even peanuts which are technically not a nut, but a legume seem to be relatively healthy. Keep in mind; you might end up canceling out the heart-healthy benefits of nuts if they're covered with chocolate, sugar or salt.

Nuts contain a lot of fat; as much as 80 percent of a nut is fat. Even though the majority of this fat is healthy fat, it's still a lot of calories. That's why you should eat nuts in moderation. Preferably, you should use nuts as a alternate for saturated fat. Instead of eating unhealthy saturated fats, try substituting a handful of nuts. Present dietary guidelines recommend eating 1 to 2 ounces (a small handful) of nuts each day. But again, do this as part of a heart-healthy diet. Just consumption of nuts and not cutting back on saturated fats establishes in many dairy and meat products won't do your heart any good.

In consideration by some researchers to help protect your cells against some forms of cancer, nuts consist of Vitamin E which is good for your health. However, the proof for Vitamin E's benefits in heart disease or cancer prevention is rather slim at the moment. One more theory is that Vitamin E might help prevent cataracts. Nuts also contain fiber, and a high-fiber diet is thought to help prevent heart disease and diabetes. A diet too much in foods that contain fiber also might help prevent colon cancer.

Nut oils are outstanding sources of omega-3 fatty acids and vitamin E. Walnut oil is highest in omega-3s. Nut oils consist of saturated and unsaturated fats. Using nut oils in homemade salad dressing or in cooking is an option. When using nut oils in cooking, keep in mind that they respond in a different way to heat than do vegetable oils. Nut oil, if overheated, can become bitter. Use nut oil in moderation to restrict overall calorie and fat intake just like with nuts.

On every continent and for thousands of years, nuts have been an important food for humans, and for good reason. Nuts are good for you they are cholesterol-free and contain healthy, unsaturated fats, which can help lower the risk of heart disease. Nuts also provide magnesium, which helps maintain bone structure; and chromium, which helps to ensure proper insulin function. They contain zinc for growth and wound healing, and manganese, which protects against free radicals.

Can Eating Nuts Help You Lower Risk of Heart Disease? - Part 1

Several large studies have linked nuts to lower heart disease risk and longer life. In the landmark Nurses' Health Study, for instance,women who ate the most nuts (about 5 oz per week) had half the risk of heart attack as those who rarely ate them. Although the power sources in nuts is unclear, researchers suggest that their unsaturated fats, magnesium, copper, folic acid, protein, potassium, fiber, and vitamin E may all play a part.

The type of nut you eat isn't that important. Almost every type of nut has a lot of nutrition packed into small package, walnuts, almonds and hazelnuts. If you have heart disease, eating nuts instead of a less healthy snack can help you more easily follow a heart-healthy diet.

Most studies on public who consume nuts as part of a heart-healthy diet have found that nuts lower the LDL, low-density lipoprotein or "bad" cholesterol level in the blood. High LDL is the main causes of heart disease, so nuts' aptitude to lower LDL cholesterol looks to be beneficial.

Consumption of nuts lessens your possibility of developing blood clots that capable of cause a fatal heart attack. Nuts also improve the health of the lining of your arteries. The facts for the heart-health benefits of nuts aren't rock-solid yet the Food and Drug Administration only allows food companies to say proof "suggests but does not prove" that eating nuts lessen heart disease risk. Still, the obtainable evidence looks promising.

Macadamia Nut Oil Benefits

Macadamia Nut oil is truly healthy and has become famous among the chefs across the world. The chefs are using the oil as it has better taste and healthy ingredients. Macadamia Nut oil can be used for preparing omelets, pancakes and baked goods. It is also widely in use as a substitute of olive oil. Its stability and versatility are two of the main reasons for which chefs all across the world are using Macadamia Nut oil. Again this oil can be used in low carbohydrate based diet. As the oil is derived from nuts, there are several good points for using the oil. So the macadamia nut oil is considered as a true culinary treasure. Though organic unblended Macadamia nut oil is hard to find, there are many Macamian nuts which are inedible. Again, often it boasts a higher smoke point than olive oil, which means that its beneficial fatty acids prevent degradation during cooking. Especially, Macadamia nut oil is good when used for salads. Macademia nut is an important food crop and it has high commercial importance. Beside culinary purposes, these nuts have diverse use. The two species of Macadamia are truly hybridized and grown in the South East of Queensland of Australia. The website www.AgCommoditiesInc.com has more details.

Moreover, the oil has no transfatty acids and the rate of saturated fat is comparatively low. So, it is the best way of enhancing heart's health. For sugar regulation and controlling diabetes, Macadamia Nut oil is highly used. But whenever consuming the oil, it is better to remember that these oils are rich in calories and excess intake can result accumulation of body fat. For cooking purposes this oil is exceedingly important because it is resistant to chemical alteration which takes place when cooked in high temperature.

Macadamia Oil: Not Just the Nuts!

Macadamia oil is probably more widely known as a delicious cooking oil than as a massage oil. Alas, the macadamia oil used for aromatherapy is not edible, but it nonetheless provides a richly sensuous experience. Combined with another, more aromatic oil, such as lemon myrtle, macadamia oil is at once calming and revitalizing. In fact, it is better used as a base oil, than all by itself.

Macadamia oil owes its success as a massage liniment to its emollient properties, which is to say it softens and soothes the skin. Since it enjoys a high affinity with the oil already naturally produced by the human skin, it is more readily absorbed by the body than a lot of other massage oils. This particular oil also helps reduce fine lines when used on the face.

The Origins of Macadamia Oil

Contrary to popular opinion, the macadamia tree is not native to the island state of Hawaii. As a matter of fact, it was only brought to Hawaii from southeast Queensland, which had been filled with rain forests -- the perfect environment for this tropical plant. The macadamia tree was introduced to Hawaii at around 1881, where its fruit evolved to its current status of being the world's most expensive nut.

Macadamia oil is 80 percent of a single macadamia nut, while sugar makes up 4 percent. The creamy, light texture of the macadamia nut makes it a popular component for confections like chocolate bars. Macadamia oil is somewhat stronger-smelling than other nut oils, such as almond, but its scent is rather sweet, and not at all unpleasant.

Macadamia Oil -- the "Vanishing Oil"

There is a special property of macadamia oil which is not found in every other massage oil. It has an unusually high level of Palmitoloeic acid units, which makes it more compatible with older skin compared to other oil brands. As the human skin ages, it tends to dry up -- that is, to produce less oil -- and the pores also tend to close. This same "aging" effect occurs when the skin is exposed frequently to the sun.

Macadamia oil seeps into the pores more easily than other massage oils, which makes it look like it is "vanishing" into the skin. Perhaps it is also known as a “vanishing” oil since it can play a role in the disappearance of wrinkles and lines. This clear liquid with a slight yellow sheen aids in melting the fat naturally stored by the skin, therefore giving the body a healthy, youthful glow that not only feels good, but looks great as well.

Macadamia Nut Oil - How it is Used

Macadamia nut oil is used specifically a couple of different ways. One is for cooking and one is for the cosmetic industry. Therefore, lets discuss both aspects and explore exactly what each different application has to offer to the consumer.

Lets begin with the cooking aspect. This will include the health benefits that are included with the ingestion too. First off, this could be used for both cooking as well as oil in a salad. The cooking capabilities are quite good and it will not smoke until it becomes over four hundred degrees Fahrenheit. It stores well and will last for over a year. It is made primarily of monounsaturated fats and is not very volatile of catch fire quickly.

It is very comparable to regular cooking oil and adds a hint of the macadamia flavor. There are versions that have been even more refined and are quite clear too but the flavor will remain.

Health benefits include niacin, iron, calcium, and proteins. But, it is this nut, and only this nut that has the highest amount of monounsaturated fats, which is very nutritious and therefore causes the macadamia nut to be so popular. However, some will argue this fact and simply just look at the taste of the nut. And, they would be correct too. Fore, not only are these specific nuts good, they are also good for you.

As far as the cosmetic aspect is concerned, it is very oxidative stable and works well in cream based products and does not feel oily. It is often compared to mink oil and is even more often substituted for it.

Therefore, eating as well as creams in the cosmetic industry are the largest consumers of macadamia nuts. Some are used in the confectioner's arena when adding them to candies, cookies, and cakes. Some are used and enjoyed in their raw form. And some have the oil extracted from them to be used in other purposes.

There is however, one single use that this is not good for and can even have detrimental effects. This is whether a dog eats them or not. These will make a dog tremendously sick. Sick to the point that the dog will not be able to move. Therefore, be aware for those who have a dog as the family pet and keep these types of nuts completely away from them. This would probably also include any oil that was used to cook with and will subsequently be used as leftovers to feed the family pet. Simply put, if there is any confusion as to whether this oil was used, eliminate all doubt and throw the leftovers away.

Regardless, the macadamia nut does provide a bevy of a variety of uses and these have shown many benefits. This said, although, it is the cosmetic industry that is probably the largest buyer and user of macadamia nut oil for use in their many products from creams to lotions and beyond, the candy industry can honestly say that they use it quite extensively too.

Low-Carb Chocolate Chip-Macadamia Nut Ice Cream Sandwiches

Who among us doesn't remember the days when we'd take two cookies and smash our favorite flavor of ice cream in the middle to eat when the temperatures outside were blistering like they are right now? Yep, we sure did and it was a great way to cool off. Unfortunately, it wasn't so good on the waistline.

Nowadays, we're eating better than we used to because we're livin' la vida low-carb (RIGHT?!) and we're shunning the sugar in our diet, too (RIGHT?!). Because of that, I'm happy to share an absolutely amazing low-carb chocolate chip-macadamia nut ice cream sandwiches recipe compliments of our friends at Low-Carb Connoisseur.

The cookies are from Big Train and I LOVE LOVE LOVE these. They taste just like toll house cookies and you'll NEVER believe they are low-carb. I was quite impressed. And the macadamia nut ice cream is the icing on the proverbial cake, so to speak. You won't want to go overboard with these, but they can be a nice oasis to beat the heat of that last blast of this summer scorcher! ENJOY! :)

LOW-CARB CHOCOLATE CHIP-MACADAMIA NUT ICE CREAM SANDWICHES

COOKIES
1 (8-ounce) package Big Train Sugar Free Chocolate Chip Cookie Mix
1 Stick butter, at room temperature
1 large egg

MACADAMIA NUT ICE CREAM
3 cups heavy cream
2 large eggs
3 large egg yolks
3/4 cup NOW Xylitol sugar substitute
1/4 teaspoon salt
2 teaspoons Singing Dog Organic vanilla extract
1/2 teaspoon almond extract
1/2 cup coarsely chopped Mac Farms macadamia nuts

1. For the cookies: Mix according to package directions, adding the butter and egg. Portion the dough to make 20 cookies. Bake and cool following the package directions; set aside.

2. For the macadamia nut ice cream: Pour heavy cream into a heavy-bottomed 3-quart saucepan and place over medium heat. Bring to a low boil, stirring often so the cream does not boil over. Remove from heat.

3. In a large bowl, place eggs, egg yolks, sugar substitute and salt. Using either a hand mixer or a whisk, beat together until thickened and smooth.

4. Using a ladle, remove about a cup of the hot cream from saucepan and gradually whisk into egg mixture (this tempers the eggs so they wont curdle). Whisking, pour tempered egg mixture into remaining cream in saucepan.

Place over medium heat and whisk until slightly thickened, 1 to 2 minutes. Pour into a clean bowl, whisk in vanilla and almond extracts; let stand until custard is completely cooled to room temperature, about 1 1/2 hours. Refrigerate 2 hours, until well chilled, or cover with plastic wrap and refrigerate overnight.

5. Freeze in ice cream maker according to manufacturers directions. Add chopped macadamia nuts 15 minutes before freezing process is complete.

6. To assemble sandwiches: Arrange 10 cookies, top side down, on work surface. Using an ice cream scoop, working quickly, place 1/4 cup ice cream on each cookie. Top each with another cookie, bottom side down. Wrap each sandwich well in plastic wrap and place in freezer. Freeze at least 4 hours (ice cream will be soft) or overnight (for firmer sandwiches). Can be stored in the freezer up to 1 month.

Mauna Loa Macadamia Nuts

Mauna Loa macadamia nuts are specifically from this Hawaiian locale known for these. They are some of the world's best and are in fact so good that these are the only types that the Hershey Company will use in their confectioners. It is their chocolate covered creations that are quite a hit with consumers and with a combination of one of the world's best nuts as well as one of the world's best chocolate, is this really any surprise.

Lets take a closer look at the macadamia nut in general and see what this very versatile nut does truly offer to the world.

We will begin with the health benefits that this nut has been proven to provide. It is very high in monounsaturated fats as well as niacin, potassium, protein, thiamine, and iron. And, not only that but, this specific nut is the one to have the highest content of this valuable benefit. Therefore, eat them liberally however; make every attempt to limit additives such as chocolate and other sugar based confections as this will detract from the overall health benefit.

The oil that comes from this nut can be used for cooking and it has a very high smoking point. That point is over four hundred degrees and therefore is very non-volatile.

Cosmetics treat it and even regard this oil as a very close companion to mink oil and this oil is used in many creams because it is stable in its oxidative state and is very high on Omega-seven, the palmitoleic acid that can be as high as seventeen percent.

However, before you get the big idea to grow one yourself, know that these will only grow in the southern hemisphere where it is basically and mostly a warmer climate. Another large aspect is the time from planting to producing that first nut time factor. These trees will mature and start producing usually around ten to twelve years. Once they do produce, barring any miscellaneous catastrophic event, they will continue to produce for many times over one hundred years.

It is actually in Hilo, Hawaii that the Mauna Loa macadamia nut factory is located. They began this highly sought after crop in nineteen forty-six, taking advantage of the rich volcanic soil as well as the constant warm moist air. However, it would be ten years before to very first nut would be harvested and when nineteen fifty-six rolled around, the fruits of their labors were prevalent in abundance.

That company that now owns these orchards is the Hershey's Company and they now provide the world with some of the best Mauna Loa macadamia nuts that are produced. Regardless of the use, whether it is for food or cosmetics, it is for sure that they will be consumed. Find out more tips about macadamia nuts at http://macadamia-nuts.researchguidetips.com

How to Cook With Macadamia Nut Oil

By Carole Vansickle

Macadamia nut oil is growing in popularity each day. This oil tastes very similar to other oils, but is far healthier than other alternatives. It is low in saturated fats, and is particularly common in "Mediterranean" diets, which are designed to be good for the heart. If you want to start using macadamia nut oil in place of vegetable or other oils, you will not make very many changes to your cooking routine.

Instruction:-

1. Start frying when the oil shimmers. Macadamia nut oil, unlike the also popular and heart-healthy olive oil, can be used hot or cold. If you are going to fry in this oil, heat the oil in the skillet until it develops a gold shimmer on the top of the oil. This lets you know that the oil is hot and ready to use to cook.

2. Spread macadamia nut oil across toasted bread to replace butter. Macadamia nut oil has many of the same taste qualities as butter. As a result, it can be used on toast or as a dip whenever you are serving bread items.

3. Use two-thirds of the measurement when replacing butter with macadamia nut oil. In many cases, you'll only need half the amount of macadamia nut oil in place of butter. However, this is not a firm measurement, so adjust the amount slightly up or down depending on the recipe. Macadamia nut oil "coats" much better than butter, so particularly when sauteing and frying, you can use half or even less of the oil than you would if you were cooking with butter.

4. Use macadamia nut oil to bake cakes that call for "liquid" fats. This means the recipe should, if possible, require melted butter or another oil rather than softened butter or shortening. You can use macadamia nut oil in place of these "solids," but the measurements are going to require a little testing to get the texture right. Start with the two-thirds mentioned above and work from there.

Notes : Macadamia nut oil is high in omega-3 fatty acids, which are good for the heart and the memory.

Oil Extraction from Nut

Many oil-bearing seeds and nuts are broken up by grinding, flaking, or rolling, then subjected to mechanical pressing to liberate the oil. The modern continuous screw press exerts pressures as high as 30,000 pounds per square inch. In modern press extraction, oilseeds or nuts are cleaned, and the shells or hulls removed; the kernels or meats are ground to a coarse meal that is pressed with or without preliminary heating. Cold-pressed oil, also called cold-drawn, or virgin, oil, is purer and has a better flavour than oil expressed with the aid of heat. After pressing the meals made from oily seeds or nuts, the remaining cake contains about 5 to 15 percent oil. Most of the oil present in these residues, and in meals made from seeds and nuts that naturally contain little oil, can be removed by extraction with volatile solvents, especially petroleum benzin (also known as petroleum ether, commercial hexane, or heptane). The solvent is percolated through the meal, dissolving the oil, which is finally recovered from the solution by evaporating the solvent. The solvent is also recovered and used over again.
