מידע כולסטרול הוא לא מקור לדאגה בצריכת יתר

[White Walker]

עפ"י הצהרה של הוועדה המייעצת לוועדה החמש- שנתית (כפי שפורסם באתר משרד הבריאות האמריקאי) :

Cholesterol. Previously, the Dietary Guidelines for Americans recommended that cholesterol intake be limited to no more than 300 mg/day." The 2015 DGAC will not bring forward this recommendation because available evidence shows no appreciable relationship between consumption of dietary cholesterol and serum cholesterol, consistent with the conclusions of the AHA/ACC report.235 Cholesterol is not a nutrient of concern for overconsumption."

אגב, חיות טורפות צורכות המון שומן רווי.. זה פוגע גם להן בכלי הדם?

אני דיי בטוח שמערכת העיכול של חיות שונות בהרבה משלנו.

אני דיי בטוח שמערכת העיכול של חיות שונות בהרבה משלנו.

מן הסתם אבל בכל זאת מעניין אם בדקו את זה..

אז ככה...
היום פורסמו המלצות התזונה של הוועדה החמש שנתית.
A Closer Look Inside Healthy Eating Patterns - 2015-2020 Dietary Guidelines - health.gov
לא נשאר כלום מהפסקה על הכולסטרול שהתייחסת אליה @White Walker
הם כתשו את המסקנות של הוועדה המייעצת וזרקו לפח את המטא שהיא הסתמכה עליה, שלפיה כולסטרול בתזונה לא משפיע על כולסטרול בדם:
Strong evidence from mostly prospective cohort studies but also randomized controlled trials has shown that eating patterns that include lower intake of dietary cholesterol are associated with reduced risk of CVD, and moderate evidence indicates that these eating patterns are associated with reduced risk of obesity
את המגבלה של ה- 300 מ״ג הם הורידו מההמלצות אבל ממליצים עדיין לשמור על צריכה נמוכה של כולסטרול עם דגש על צמצום במזונות שמכילים שומן רווי וכולסטרול. במילים אחרות, מי שכן צורך כולסטרול מהחי- עדיף על פי ההמלצות לצרוך דברים כמו ביצים וחלק מפירות הים שעשירים בכולסטרול אבל לא בשומנים רוויים מאשר במוצרי בשר עתיר שומן רווי וכולסטרול גם יחד.

The body uses cholesterol for physiological and structural functions but makes more than enough for these purposes. Therefore, people do not need to obtain cholesterol through foods.

The Key Recommendation from the 2010 Dietary Guidelines to limit consumption of dietary cholesterol to 300 mg per day is not included in the 2015 edition, but this change does not suggest that dietary cholesterol is no longer important to consider when building healthy eating patterns. As recommended by the IOM,[24] individuals should eat as little dietary cholesterol as possible while consuming a healthy eating pattern. In general, foods that are higher in dietary cholesterol, such as fatty meats and high-fat dairy products, are also higher in saturated fats. The USDA Food Patterns are limited in saturated fats, and because of the commonality of food sources of saturated fats and dietary cholesterol, the Patterns are also low in dietary cholesterol. For example, the Healthy U.S.-Style Eating Pattern contains approximately 100 to 300 mg of cholesterol across the 12 calorie levels. Current average intake of dietary cholesterol among those 1 year and older in the United States is approximately 270 mg per day.

Strong evidence from mostly prospective cohort studies but also randomized controlled trials has shown that eating patterns that include lower intake of dietary cholesterol are associated with reduced risk of CVD, and moderate evidence indicates that these eating patterns are associated with reduced risk of obesity. As described earlier, eating patterns consist of multiple, interacting food components and the relationships to health exist for the overall eating pattern, not necessarily to an isolated aspect of the diet. More research is needed regarding the dose-response relationship between dietary cholesterol and blood cholesterol levels. Adequate evidence is not available for a quantitative limit for dietary cholesterol specific to the Dietary Guidelines.

Dietary cholesterol is found only in animal foods such as egg yolk, dairy products, shellfish, meats, and poultry. A few foods, notably egg yolks and some shellfish, are higher in dietary cholesterol but not saturated fats. Eggs and shellfish can be consumed along with a variety of other choices within and across the subgroup recommendations of the protein foods group.
