Key et al (7) have provided a pertinent overview of the health effects of vegetarian diets, focusing on their European Prospective Investigation. Cancer and Nutrition–Oxford (EPIC- Oxford) study and other large population studies. In general, vegetarians typically enjoy a lower risk of cardiovascular disease (CVD), obesity, type 2 diabetes, and some. A vegan diet appears to be useful for increasing the intake of protective nutrients and phytochemicals and for minimizing. In a recent report (1. According to the evidence criteria of the World Health Organization and Food and Agriculture Organization (WHO/FAO). CVD reduction as convincing, whereas lower risk of osteoporosis was assessed as probable (1. ![]() ![]() The evidence for a risk- reducing effect of consuming whole grains was assessed as possible for colorectal cancer and probable. CVD. The evidence for a risk- reducing effect of consuming nuts was assessed as probable for CVD (1. This is true not only for whites; work by Toohey et al (1. BMI; in kg/m. 2) were significantly lower in African American vegans than in lactoovovegetarians. Similarly, among Latin Americans, vegetarians. In that study, plasma total and LDL cholesterol were 3. Because obesity. is a significant risk factor for CVD, the substantially lower mean BMI observed in vegans may be an important protective factor. A higher consumption of fruit and vegetables, which are rich in fiber, folic acid, antioxidants, and phytochemicals, is. Vegans also have a higher consumption of whole grains, soy, and nuts (1. A vegetarian diet provides a variety of cancer- protective dietary factors (2. In addition, obesity is a significant factor, increasing the risk of cancer at a number of sites (2. Because the mean BMI of vegans is considerably lower than that of nonvegetarians (8), it may be an important protective factor for lowering cancer risk. All those foods and nutrients are protective against cancer (2. Comments for Gas and Bloating From Vegan Diet. Average Rating. Click here to add your own comments.

In addition, fiber, vitamin C, carotenoids, flavonoids, and other phytochemicals in the diet are shown to exhibit. Foods rich in lycopene, such as tomatoes, are known to protect against prostate cancer (2. The phytochemicals interfere with several cellular processes involved in the progression of cancer. These mechanisms include. DNA adduct formation, inhibiting phase 1 enzymes, inhibiting signal transduction. ![]() The bioavailability of the phytochemicals, which depends among other things on food preparation methods, may be an important. However, new evidence suggests that a low vitamin D status, a problem often reported in vegan populations. Red meat and processed meat consumption. Those in the highest quintile of red meat intake had elevated risks, ranging from 2. In addition, the use of eggs was recently shown to be associated with a higher risk of pancreatic cancer (3. Although vegans avoid consuming red meat and eggs altogether, they consume greater amounts of legumes than do omnivores. This protein source was seen in the Adventist Health Study to be negatively associated with risk of colon cancer (2. New data suggest that legume intake is also associated with a moderate reduction in the risk of prostate cancer (3. In Western society, vegans also consume substantially more tofu and other soy products than do omnivores (1. Consumption of isoflavone- containing soy products during childhood and adolescence protects women against the risk of breast. Cancer risk in vegans may be altered because vegans consume soy beverages rather than dairy beverages. Data from the Adventist. Health Study showed that consumption of soy milk by vegetarians protected them against prostate cancer (3. To date, epidemiologic studies have not provided convincing. Although plant foods contain many chemopreventive. More recent studies with postmenopausal Asian women showed spine or hip BMD was significantly lower in long- term vegans. Those Asian women, who were vegetarian for religious reasons, had low intakes of protein and calcium. An inadequate protein. Adequate calcium intake may be a problem for vegans. Although lactoovovegetarians generally consume adequate amounts of. Results from the EPIC- Oxford study provide good evidence that the risk of bone fractures for vegetarians was similar to. Lydia Dziubanek Lost 80 Pounds: Apr 12, 2012 A Vegan Diet is Not Healthy. I’m mentally preparing myself for this one. Because it’s inevitable I’ll receive at least a few heated comments on.

When I went vegan I was in a relationship with a guy that was vegetarian, so the switch was pretty easy. When we broke up I never realized how hard dating and being a. The higher risk of bone fracture seen in vegans appears to be a consequence of a lower mean calcium intake. No difference. was observed between the fracture rates of the vegans who consumed > 5. Research has shown that bone health is also influenced. D, vitamin K, potassium, and magnesium and by foods such as soy and fruit and vegetables (4. Vegan diets do well in providing a number of those important substances. The maintenance of acid- base balance is critical. A drop in extracellular p. H stimulates bone resorption (5. H drop. An acid- forming diet, therefore, increases urinary calcium excretion. However, a diet rich in fruit and vegetables that is typical of a vegan diet has a positive effect on the calcium economy. The high potassium and magnesium content of fruit and vegetables provides an alkaline ash, which inhibits bone resorption. Higher intakes of potassium are associated with greater BMD of the femoral neck and lumbar spine of premenopausal women. Results from 2 large, prospective cohort studies support an association between vitamin K intake and relative risk of hip. In the Nurses’ Health Study, middle- aged women consuming the most vitamin K had the lowest risk of hip fracture. In the Framingham Heart Study, elderly men and women in the highest quartile of vitamin K intake had a 6. Soy isoflavones are suggested to have a beneficial effect on bone health in postmenopausal women (5. In a meta- analysis of 1. BMD of menopausal. In another meta- analysis, soy isoflavones significantly inhibited bone resorption and stimulated bone formation compared. In a randomized clinical trial lasting 2. BMD of both lumbar. However, more studies are needed to provide more. Second, accessibility is important, ie, the availability of certain foodstuffs and foods fortified with key. This accessibility will vary greatly, depending on the geographic region. The following section deals with nutrients of. The problem of insufficient calcium has already been discussed in the section on bone health. The plant- based n–3 fatty acid . Compared with nonvegetarians, vegetarians, and especially vegans, tend to have lower blood concentrations of EPA and DHA. However, vegans can obtain DHA from microalgae supplements containing DHA, as well as from foods fortified with DHA. However. EPA can be obtained from the retroconversion of DHA in the body. The oil from brown algae (kelp) has also been identified. EPA. Presently, the intake of EPA plus DHA in the United States is only 0. DHA. intake being . Vegans should be able to easily reach the n–3 fatty acid requirements by including regular supplies of ALA- rich foods in. DHA- fortified foods and supplements. However, DHA supplements should be taken with caution. Although they. can lower plasma triacylglycerol, they can raise total and LDL cholesterol (6. For a vegan, vitamin D status depends on both sun exposure and the intake of vitamin D- fortified foods. Those living in. areas of the world without fortified foods would need to consume a vitamin D supplement. Living at high latitudes can also. D status, because sun exposure in that region is inadequate for several months of the year (6. Those who are dark skinned, elderly, who extensively cover their body with clothing for cultural reasons, and who commonly. D deficiency (4. 5). Another matter of concern for vegans is that vitamin D2, the form of vitamin D acceptable to vegans, is substantially less bioavailable than the animal- derived vitamin D3 (6. Throughout the year serum 2. D concentrations were lower and parathyroid hormone higher in vegan women than. BMD in the lumbar region of the spine was 1. However, hemoglobin concentrations and the. Vegans often consume large amounts of vitamin C–rich foods that markedly improve the absorption of the nonheme iron. Serum. ferritin concentrations are lower in some vegans, whereas the mean values tend to be similar to the mean values of other vegetarians. The physiologic significance of low serum ferritin concentrations is uncertain at this time. Elevated homocysteine has been considered a risk factor for CVD (7. Vitamin B- 1. 2 deficiency can produce abnormal neurologic and psychiatric symptoms that include ataxia, psychoses, paresthesia. In addition, children may experience apathy and failure to thrive, and macrocytic anemia is a common feature at all ages. Phytates, a common component of grains, seeds, and legumes. However, a sensitive marker to measure zinc status in humans has not. Although vegans have lower zinc intake than omnivores, they do not differ from the nonvegetarians in functional immunocompetence. It appears that there may be facilitators of zinc absorption and compensatory mechanisms to help vegetarians adapt to a.
