Het goede van eieren.*

Uit negen studies blijkt dat eieren heel gezond zijn. Eieren bevorderen het afvallen en zijn een goede bron van choline, een belangrijk nutriŽnt dat de ontwikkeling van de hersenen en hersenfuncties doet bevorderen.

In een studie over de effecten bij afvallen onder vrouwen met overgewicht kregen een deel van de vrouwen 8 weken lang dagelijks extra 2 eieren bij het ontbijt. Na 8 weken hadden deze vrouwen 65% meer gewicht verloren en had ruim 80% minder taille-omtrek dan de vrouwen die geen eieren gegeten hadden. Geen verschillen in cholesterolwaarden werden gemeten in beide groepen vrouwen.

Eieren zijn een goede bron van choline, ongeveer 125 mg per ei. Met 2 eieren per dag heb je al de helft van de dagelijkse hoeveelheid choline binnen. Slechts 10% van de bevolking krijgt per dag voldoende choline binnen. Choline is een essentieel nutriŽnt voor de ontwikkeling van hersencellen en de hersenfuncties. Daarom is voldoende choline in de voeding cruciaal voor zwangere vrouwen en 65 plussers. De angst dat het eten van eieren slecht zou zijn voor hart- en bloedvaten blijkt volgens onderzoek niet gegrond te zijn, eieren doen de kans op een hartziekte slechts met een half procent verhogen en dat weegt niet op tegen alle gezonde nutriŽnten zoals o.m. de carotenoÔden als luteÔne en zeaxanthine die staar en macula degeneratie tegengaan.

 

 

9 Studies Presented At Experimental Biology 2007 Confirm The Importance Of Eggs In A Healthy Diet

Nine studies presented at the Experimental Biology 2007 meeting support the growing body of research on the nutritional benefits of egg consumption, including its promotion of weight loss and its role in providing choline, an essential nutrient often lacking in the diet that promotes brain and memory development and function.
Among the findings presented at Experimental Biology:
Eggs for Breakfast Help Promote Weight Loss
A randomized control trial led by Nikhil V. Dhurandhar, Ph.D., associate professor in the department of infection and obesity at Louisiana State University's Pennington Biomedical Research Center found that overweight and obese women who consumed a breakfast of two eggs a day (for five days a week or more) for 8 weeks, as part of a low-fat diet with a 1,000 calorie deficit:
* lost 65 percent more weight
* had 83 percent greater reductions in waist circumference
* reported greater improvements in energy levels than their dieting counterparts who consumed a bagel breakfast of the same calories1
This study further substantiates the findings of a previous study, published in the Journal of the American College of Nutrition,2 which found that an egg breakfast induced greater satiety and significantly reduced short-term food intake compared to a calorically equivalent bagel breakfast. In both studies, the egg and bagel breakfasts not only provided the same amount of calories, but also the same weight mass, an important control factor in satiety and weight loss studies. Also of note, the study found no significant differences between the plasma total-, HDL- and LDL-cholesterol and triglyceride levels of either group.
Closing the Choline Gap with Eggs
Researchers at Iowa State University assessed choline intake in the diets of specific subsets of the U.S. population and found that usual intake is far below the Adequate Intake (AI) levels for older children, men, women and pregnant women.3
* Only 10 percent or less of these populations are eating close to the recommended amounts of choline. This study ÔŅĹ" which is one of the first to assess choline intake in the population - is important because choline is an essential nutrient needed for normal functioning of all cells and for brain function.
* The finding that choline intake is low among pregnant women is particularly noteworthy as previous research has demonstrated that choline may help with brain and memory development in fetuses. 4, 5 The National Academy of Sciences recommends increased choline for pregnant and breastfeeding women (550 mg and 450 mg, respectively).
* Additionally, a separate study presented at this week's National Nutrient Data Bank Conference found that choline intake decreases with age and that adults ages 71 and older consume an average of about 264 milligrams per day - roughly half of the AI for choline (550 mg/day for men, 425 mg/day for women). 6
* Both studies recommend increased consumption of foods that are good sources of choline to help close the gap on choline consumption. Eggs are an excellent source of choline. Two eggs contain about 250 milligrams of choline, or roughly half the recommended daily supply. (Other rich sources of choline include beef liver and wheat germ.)
Putting Egg Recommendations Into Perspective
Researchers are beginning to challenge egg consumption restrictions that are based on studies that examined dietary cholesterol and saturated fat together. Research on the independent effect of dietary cholesterol shows no significant effect on heart disease risk.
* A relative risk study conducted by the Washington, DC-based scientific consulting firm Exponent concluded that eggs' contribution to coronary heart disease risk is insignificant. 7 The study evaluated the relative risk of heart disease associated with egg consumption compared to other risk factors, including age, genetics, dietary pattern, smoking, alcohol consumption, high blood pressure, serum cholesterol, obesity, diabetes and sedentary lifestyle. After a thorough scientific review of the major studies concerning heart disease causation, it was found that eggs contribute just 0.6 percent of males' and 0.4 percent of females' coronary heart disease risk, when other modifiable risk factors are assumed.
* Research like this may help change wide-sweeping recommendations to restrict egg consumption to avoid heart disease, particularly when the positive nutrition contributions from eggs are considered. Eggs contain a number of nutrients in varying amounts - including the highest-quality protein, choline, folate, iron and zinc - for only about 75 calories. Eggs also contain small amounts of lutein and zeaxanthin, which may be involved in the prevention of cataracts and age-related macular degeneration.
