    Butter Leads to Lower Blood Fats Than Olive Oil, Study Finds

    ScienceDaily (Feb. 9, 2010) — High blood fat levels normally raise the cholesterol values in the blood, which in turn elevates the risk of atherosclerosis and heart attack. Now a new study from Lund University in Sweden shows that butter leads to considerably less elevation of blood fats after a meal compared with olive oil and a new type of canola and flaxseed oil. The difference was stronger in men than in women.

    The main explanation for the relatively low increase of blood fat levels with butter is that about 20 percent of the fat in butter consists of short and medium-length fatty acids. These are used directly as energy and therefore never affect the blood fat level to any great extent. Health care uses these fatty acids with patients who have difficulty taking up nutrition -- in other words, they are good fatty acids.

    "A further explanation, which we are speculating about, is that intestinal cells prefer to store butter fat rather than long-chain fatty acids from vegetable oils. However, butter leads to a slightly higher content of free fatty acids in the blood, which is a burden on the body," explains Julia Svensson, a doctoral candidate in Biotechnology and Nutrition at Lund University.

    The greater difference in men is due to, among other things, hormones, the size of fat stores, and fundamental differences in metabolism between men and women, which was previously known. This situation complicates the testing of women, since they need to be tested during the same period in the menstruation cycle each time in order to yield reliable results.

    "The findings provide a more nuanced picture of various dietary fats. Olive oil has been studied very thoroughly, and its benefits are often extolled. The fact that butter raises blood cholesterol in the long term is well known, whereas its short-term effects are not as well investigated. Olive oil is good, to be sure, but our findings indicate that different food fats can have different advantages," emphasizes Julia Svensson.

    "Finally, all fats have high energy content, and if you don't burn what you ingest, your weight will go up, as will your risk of developing diseases in the long run," she reminds us.

    Here's how the test was done: 19 women and 28 men participated in the study. Each individual ate three test meals containing canola-flaxseed oil, butter, or olive oil. The day before the test they had to fast after 9 p.m. The following morning a fasting blood sample was drawn to check their health status and all blood fats. The test meal consisted of the test fat mixed into hot cream of wheat, 1.5-% milk, blackberry jam, and a slice of bread with ham. The meal contained 35 g of test fat and about 810 Kcal. Blood samples were then drawn 1, 3, 5, and 7 h after the meal, and all blood fats were analyzed. The participants fasted during the day.

  2. hmm this is interesting. Great read

  3. Nice read but am I the only one who is getting fed up with these new studies coming out pretty much every day? One study shows a particular substance is bad and then the next study shows it's the best thing that you can have. I've just come to the conclusion that everything can be good or bad and I just try to have a bit of everything in my diet in moderation.

    Next on my shopping list is chocolate - http://www.bbc.co.uk/news/health-17511011 and http://jp.physoc.org/content/589/18/4615.full

    During exercise, skeletal muscle performance depends in great part on the use of aerobic metabolism to supply the energetic demand of contractions. Endurance training increases the muscle aerobic capacity, which is not only associated with enhanced exercise performance, but also with a decreased risk of cardiovascular and metabolic diseases. Recently, it has been shown that regular use of small doses of dark chocolate may result in similar health benefits to exercise training. We show here that mice fed for 15 days with (–)-epicatechin (present in dark chocolate) had improved exercise performance accompanied by: (1) an increased number of capillaries in the hindlimb muscle; and (2) an increased amount of muscle mitochondria as well as signalling for mitochondrial biogenesis. These results suggest that (–)-epicatechin increases the capacity for muscle aerobic metabolism, thereby delaying the onset of fatigue. These findings may have potential application for clinical populations experiencing muscle fatigue.
    Which supp company do you think will be the first to include epicatechin or even a chunk of dark chocolate in their pre-workout?

  4. I use grass fed butter for cooking and EVOO for things like salads and low heat cooking.
