Miraculous health benefits of Almonds

Almonds are a very good source of vitamin E and manganese. Almonds are a good source of magnesium, copper, riboflavin (vitamin B2), and phosphorus. Fortunately, although one-quarter cup of almonds contains about 18 grams of fat, most of it (11 grams) is heart-healthy monounsaturated fat.


Almonds


Almonds are high in monounsaturated fats, the same type of health-promoting fats as are found in olive oil, which have been associated with reduced risk of heart disease. Five large human epidemiological studies, including the Nurses Health Study, the Iowa Health Study, the Adventist Health Study and the Physicians Health Study, all found that nut consumption is linked to a lower risk for heart disease. Researchers who studied data from the Nurses Health Study estimated that substituting nuts for an equivalent amount of carbohydrate in an average diet resulted in a 30% reduction in heart disease risk. Researchers calculated even more impressive risk reduction--45%--when fat from nuts was substituted for saturated fats (found primarily found in meat and dairy products).



Lessening after-meal surges in blood sugar helps protect against diabetes and cardiovascular disease, most likely by lessening the increase in cholesterol-damaging free radicals that accompanies large elevations in blood sugar. This is one reason why low- glycemic index diets result in lower risk of diabetes and heart disease.
Almonds appear to not only decrease after-meal rises in blood sugar, but also provide antioxidants to mop up the smaller amounts of free radicals that still result. (Jenkins DJ, Kendall CW, Journal of Nutrition)

Even individuals who are experiencing problems with their blood fat levels may not automatically need to shy away from high-fat food snacks like almonds. Researchers at the University of Toronto, Canada have shown that a 2.5 ounce snack of almonds each day can do a better job in lowering blood LDL and raising blood HDL than a whole wheat muffin having the same amount of fat and fiber as almonds. They also found that markers of antioxidant status in the body could be improved with the incorporation of almond snacks. It was the many phytonutrients (especially flavonoids) found in almonds that were believed to account for some of these special almond benefits.
Whole Almonds (with Skins) Provide Most Heart Healthy Benefits
New research on almonds adds to the growing evidence that eating whole foods is the best way to promote optimal health.
The flavonoids found in almond skins team up with the vitamin E found in their meat to more than double the antioxidant punch either delivers when administered separately, shows a study published in the Journal of Nutrition.
Twenty potent antioxidant flavonoids were identified in almond skins in this study, some of which are well known as major contributors to the health benefits derived from other foods, such as the catechins found in green tea, and naringenin, which is found in grapefruit.

A study published in the International Journal of Obesity and Related Metabolic Disorders that included 65 overweight and obese adults suggests that an almond-enriched low calorie diet (which is high in monounsaturated fats) can help overweight individuals shed pounds more effectively than a low calorie diet high in complex carbohydrates. Those on the almond-enriched low calorie diet consumed 39% of their calories in the form of fat, 25% of which was monounsaturated fat. In contrast, those on the low calorie diet high in complex carbohydrates consumed only 18% of their calories as fat, of which 5% was monounsaturated fat, while 53% of their calories were derived from carbohydrate. Both diets supplied the same number of calories and equivalent amounts of protein. After 6 months, those on the almond-enriched diet had greater reductions in weight (-18 vs. -11%), their waistlines (-14 vs. -9%), body fat (-30 vs. -20%), total body water (-8 vs. -1%), and systolic blood pressure (-11 vs. 0%). Those eating almonds experienced a 62% greater reduction in their weight/BMI (body mass index), 50% greater reduction in waist circumference, and 56% greater reduction in body fat compared to those on the low calorie high carbohydrate diet! Among those subjects who had type 1 diabetes, diabetes medication reductions were sustained or further reduced in 96% of those on the almond-enriched diet versus in 50% of those on the complex carbohydrate diet.


Although nuts are known to provide a variety of cardio-protective benefits, many avoid them for fear of weight gain. A prospective study published in the journal Obesity shows such fears are groundless. In fact, people who ate nuts at least twice a week were much less likely to gain weight than those who almost never ate nuts.
The 28-month study involving 8,865 adult men and women in Spain, found that participants who ate nuts at least two times per week were 31% less likely to gain weight than were participants who never or almost never ate nuts.
And, among the study participants who gained weight, those who never or almost never ate nuts gained more (an average of 424 g more) than those who ate nuts at least twice weekly.
Study authors concluded, "Frequent nut consumption was associated with a reduced risk of weight gain (5 kg or more). These results support the recommendation of nut consumption as an important component of a cardioprotective diet and also allay fears of possible weight gain."


Almonds are a very good source of manganese and a good source of copper, two trace minerals that are essential cofactors of a key oxidative enzyme called superoxide dismutase. Superoxide dismutase disarms free radicals produced within the mitochondria (the energy production factories within our cells), thus keeping our energy flowing. Fortunately, Mother Nature supplies both mineral cofactors in almonds. Just one-quarter cup of almonds supplies 45.0% of the daily value for manganese, and 20.0% of the daily value for copper. Riboflavin (vitamin B2) also plays at least two important roles in the body's energy production. When active in energy production pathways, riboflavin takes the form of flavin adenine dinucleotide (FAD) or flavin mononucleotide (FMN). In these forms, riboflavin attaches to protein enzymes calledflavoproteins that allow oxygen-based energy production to occur.
Flavoproteins are found throughout the body, particularly in locations where oxygen-based energy production is constantly needed, such as the heart and other muscles. Riboflavin's other role in energy production is protective.


Twenty years of dietary data collected on over 80,000 women from the Nurses' Health Study shows that women who eat least 1 ounce of nuts, peanuts or peanut butter each week have a 25% lower risk of developing gallstones. Since 1 ounce is only 28.6 nuts or about 2 tablespoons of nut butter, preventing gallbladder disease may be as easy as having a handful of almonds as an afternoon pick me up, tossing some almonds on your oatmeal or salad or packing one almond butter and jelly sandwich (be sure to use whole wheat bread for its fiber, vitamins and minerals) for lunch each week.

Almonds are concentrated in protein. A quarter-cup contains 7.62 gramsâ€"more protein than is provided by the typical egg, which contains 5.54 grams.
