כמה קשה/מה צריך לעשות בארץ כדי לקבל בדיקת דם לסוגי LDL?
Sponsor(s): Texas A&M University
Conditions to be treated: Sarcopenia; Cardiovascular Disease
Purpose: The purpose of this study is to examine the effect of dietary cholesterol administered as whole egg or egg white (control)on muscle mass gain with resistance training in a young old population of men and women (age 50-69). It is hypothesized that dietary cholesterol will be significantly associated to muscle mass gain.
Further study details as provided by Texas A&M University:
Primary Outcomes: Primary: Strength and muscle gain (DEXA) after 12 weeks of resistance training
Secondary Outcomes: Secondary: Blood lipids, inflammatory markers, blood pressure after 12 weeks of resistance training
Expected Total Enrollment: 36
Study start: November 2005; Expected completion: October 2007
Last follow-up: January 2007; Data entry closure: May 2007
The primary objective of this proposal is to have 36 men and women (age 50-69) perform 12 weeks of resistance exercise training for the purpose of inducing skeletal muscle hypertrophy. These individuals will consume either 0, 1, or 3 whole eggs per day in a double-blind design to test the hypothesis that dietary cholesterol is essential for skeletal muscle hypertrophy. If so proven, this will confirm a very strong association between dietary cholesterol and hypertrophy observed in a previous study of 51 men and women (age 60-69). The current proposal is using a randomized double-blind, placebo controlled design to provide the most conclusive evidence that dietary cholesterol plays an essential role in skeletal muscle hypertrophy.
The secondary objective of this proposal is to test the hypothesis that increased dietary cholesterol consumption in the context of an exercise program does not alter blood cholesterol concentrations or other cardiovascular risk factors.

Carbohydrate-restricted diets (CRD) significantly decrease body weight and independently improve plasma triglycerides (TG) and HDL cholesterol (HDL-C). Increasing intake of dietary cholesterol from eggs in the context of a low-fat diet maintains the LDL cholesterol (LDL-C)/HDL-C for both hyper- and hypo-responders to dietary cholesterol. In this study, 28 overweight/obese male subjects (BMI = 25–37 kg/m2) aged 40–70 y were recruited to evaluate the contribution of dietary cholesterol from eggs in a CRD. Subjects were counseled to consume a CRD (10–15% energy from carbohydrate) and they were randomly allocated to the EGG group [intake of 3 eggs per day (640 mg/d additional dietary cholesterol)] or SUB group [equivalent amount of egg substitute (0 dietary cholesterol) per day]. Energy intake decreased in both groups from 10,243 ± 4040 to 7968 ± 2401 kJ (P < 0.05) compared with baseline. All subjects irrespective of their assigned group had reduced body weight and waist circumference (P < 0.0001). Similarly, the plasma TG concentration was reduced from 1.34 ± 0.66 to 0.83 ± 0.30 mmol/L after 12 wk (P < 0.001) in all subjects. The plasma LDL-C concentration, as well as the LDL-C:HDL-C ratio, did not change during the intervention. In contrast, plasma HDL-C concentration increased in the EGG group from 1.23 ± 0.39 to 1.47 ± 0.38 mmol/L (P < 0.01), whereas HDL-C did not change in the SUB group. Plasma glucose concentrations in fasting subjects did not change. Eighteen subjects were classified as having the metabolic syndrome (MetS) at the beginning of the study, whereas 3 subjects had that classification at the end. These results suggest that including eggs in a CRD results in increased HDL-C while decreasing the risk factors associated with MetS.

תודה 😃לא יודע. אני זוכר שאלון ניסה להשיג אבל אני לא יודע מה יצא מזה.
בכל מקרה אני חושב שזה מיותר.
תקרא את זה, אבל השורה התחתונה היא:
"Individuals with TG below 70 do not have small, dense LDL. It would not be necessary to measure LDL particle size in these individuals."
תעשה בדיקה רגילה של טריגליצרידים. אם יש לך פחות מ-70 אתה לא צריך להיות מודאג.
מישהו מכיר פה את הסרט Fat Head?
דוקומנטרי. ממולץ בחום!!
מדבר על כל זה. וגם דיי מסביר מאיפה כל זה בא ולמה המצב כמו שהוא.
אני יכול להגיד לך שחוץ ממני (שאני קורא את פאבמד בזמני הפנוי כמו משה) אף אחד לא באמת יודע איך נראה מחקר. וזה אחרי שנה שלמה של לימודים.חבל שלא מלמדים (כי כנראה זה לא ברור מאליו) שצריך להתעדכן כל הזמן במחקרים חדשים.
אתמול אכלתי 21 ביצים שלמות. מי משלם לי לבוא למחקר?
