Fish Oil Consumption and Reduction of Arterial Disease -- Vanschoonbeek et al. 133 (3):... - 0 views

  •  
    Here we propose that the beneficial effect of (n-3) PUFA diet is related to down-regulation of the mutually positive interactions of platelet activation and coagulation. In addition, we consider the possibility that the dietary effect on hemostatic and lipid factors involves transcription regulation of multiple genes, perhaps in a subject-dependent manner. Fish oil consumption and reduction of arterial disease. Vanschoonbeek K, de Maat MP, Heemskerk JW. J Nutr. 2003 Mar;133(3):657-60. Review. PMID: 12612132

Vitamin K - Linus Pauling Institute at Oregon State University - 0 views

  •  
    Vitamin K is a fat-soluble vitamin. The "K" is derived from the German word "koagulation." Coagulation refers to the process of blood clot formation. Vitamin K is essential for the functioning of several proteins involved in blood clotting (1). There are two naturally occurring forms of vitamin K

    Vitamin K has been known as the coagulation vitamin, because of its role in the blood-clotting process. However, research over the last few decades has shown that the role of K Vitamins - and natural Vitamin K2, the menaquinones, in particular - has been greatly expanded. Of note, K Vitamins activity outside the liver is required for calcium utilization, the key factor in maintaining both bone and cardiovascular health.\n\nVitamin K2 helps to activate vitamin K-dependent proteins responsible for healthy tissues. In bone, it activates osteocalcin, a protein required to bind calcium to the mineral matrix, thus strengthening the skeleton. In circulation, Vitamin K2 participates in carboxylation of Matrix Gla Protein (MGP), the most potent inhibitor of arterial calcification known, lowering the risk of vascular damage.

    Vitamin K content of foods and dietary vitamin K intake in Japanese young women. Kamao M, Suhara Y, Tsugawa N, Uwano M, Yamaguchi N, Uenishi K, Ishida H, Sasaki S, Okano T. J Nutr Sci Vitaminol (Tokyo). 2007 Dec;53(6):464-70. PMID: 18202532 Several reports indicate an important role for vitamin K in bone health as well as blood coagulation. However, the current Adequate Intakes (AI) might not be sufficient for the maintenance of bone health. To obtain a closer estimate of dietary intake of phylloquinone (PK) and menaquinones (MKs), PK, MK-4 and MK-7 contents in food samples (58 food items) were determined by an improved high-performance liquid chromatography method. Next, we assessed dietary vitamin K intake in young women living in eastern Japan using vitamin K contents measured here and the Standard Tables of Food Composition in Japan. PK was widely distributed in green vegetables and algae, and high amounts were found in spinach and broccoli (raw, 498 and 307 microg/100 g wet weight, respectively). Although MK-4 was widely distributed in animal products, overall MK-4 content was lower than PK. MK-7 was observed characteristically in fermented soybean products such as natto (939 microg/100 g). The mean total vitamin K intake of all subjects (using data from this study and Japanese food composition tables) was about 230 microg/d and 94% of participants met the AI of vitamin K for women aged 18-29 y in Japan, 60 microg/d. The contributions of PK, MK-4 and MK-7 to total vitamin K intake were 67.7, 7.3 and 24.9%, respectively. PK from vegetables and algae and MK-7 from pulses (including fermented soybean foods) were the major contributors to the total vitamin K intake of young women living in eastern Japan

The Heart Scan Blog: Cheese and vitamin K2 - 0 views

  •  
    If you've been following the Track Your Plaque conversation, you know that, contrary to prevailing opinion among many cardiologists, there is an emerging notion that coronary calcification is an active process, a true part of the disease. Vitamin D3 is an important aspect of this question. So is vitamin K2. Not to be confused with K1 that plays a role in blood coagulation, K2 has an important role in calcium metabolism. Thus, vitmain K2 deficiency is related to osteoporosis and to coronary calcification.

Tofu - Wikipedia, the free encyclopedia - 0 views

  •  
    "Tofu (豆腐, tōfu?), or bean curd[5] is a soft white food made by coagulating soy milk, and then pressing the resulting curds into blocks. It is of Chinese origin,[6] and part of East Asian and Southeast Asian cuisine such as Chinese, Japanese, Korean, Indonesian, Vietnamese[7] and others.[8] There are many different varieties of tofu, including fresh tofu and tofu that has been processed in some way. Tofu has very little flavor or smell on its own, so it can be used either in savory or sweet dishes, and is often seasoned or marinated to suit the dish A study done by the Pacific Health Research Institute followed over 3000 Japanese men between 1965 and 1999, which showed a positive correlation between cerebral atrophy and consumption of tofu.[42] However, this study by L.R. White, et al., from the National Institute of Aging, NIH, was rejected as not credible by the Food and Drug Administration."

A Diet Rich in Coconut Oil Reduces Diurnal Postprandial Variations in Circula... - 0 views

    A diet rich in coconut oil reduces diurnal postprandial variations in circulating tissue plasminogen activator antigen and fasting lipoprotein (a) compared with a diet rich in unsaturated fat in women. Müller H, Lindman AS, Blomfeldt A, Seljeflot I, Pedersen JI. J Nutr. 2003 Nov;133(11):3422-7. PMID: 14608053 In conclusion, our results indicate that a coconut oil-based diet (HSAFA-diet) lowers postprandial t-PA antigen concentration, and this may favorably affect the fibrinolytic system and the Lp(a) concentration compared with the HUFA-diet. The proportions of dietary saturated fatty acids more than the percentage of saturated fat energy seem to have a beneficial influence on Lp(a) levels. The connection between Lp(a) and atherosclerosis is not entirely understood. Different studies have provided strong evidence that Lp(a) level is an independent risk factor for developing coronary artery disease in men (47,48), but the question of causality continues to be debated. Recent data suggest that Lp(a) might be atherogenic (49), in particular when combined with other risk factors. High levels of Lp(a) combined with other risk factors such as the ratio of plasma total/HDL cholesterol have been shown to increase the risk for coronary heart diseases (50). It has also been reported that when substantial LDL cholesterol reductions were obtained in men with coronary heart disease, persistent elevations of Lp(a) were no longer atherogenic or clinically threatening (51). In conclusion, the present results show that the HSAFA-diet lowered postprandial t-PA antigen and thus potentially improved fibrinolysis compared with the HUFA-diet. Diets with either high or low levels of saturated fatty acids from coconut oil beneficially decrease Lp(a) compared with a HUFA-diet. The proportions of dietary saturated fatty acids more than the percentage of saturated fat energy may be of importance if the goal is to decrease Lp(a).
