UK – Official new data shows that today’s eggs contain more than 70 per cent more vitamin D and double the amount of selenium than when previous analyses were carried out 30 years ago.

Today’s eggs also contain around 20 per cent less fat, more than 20 per cent less saturated fat, around 13 per cent fewer calories and more than 10 per cent less cholesterol than previous surveys suggested. An average medium egg now contains 66 calories (compared to the previous figure of 78 calories) and an average large egg 77 calories (previously 91 calories).

The data, produced by the UK Foodcomp project consortium, funded by the Department of Health as part of their rolling programme of nutrient analysis surveys, provides the first update on the nutrient content of eggs since the 1980s.

Professor Judith Buttriss, Director General of the BNF, explained: “This is the latest in a series of analyses from the DH-funded UK Foodcomp project that provide up to date information on the composition of the food we eat. These particular data reinforce the contribution to essential nutrients that eggs can make as part of a varied diet, for people of all ages.”

The new analysis, part of which is being presented at The Nutrition Society’s Summer Meeting on 18 July, found that two medium eggs can provide around two-thirds of the RDA (Recommended Daily Amount for EU labelling purposes) for vitamin D. The additional vitamin D found in eggs is particularly significant in the light of evidence suggesting that a large proportion of people in the UK have an inadequate supply of this vitamin.

It has been suggested that, in addition to the well-established role of vitamin D in bone health, this nutrient may also play a role in the immune system and beneficially influence the incidence of some cancers, cardiovascular disease and diabetes.

“This is a very welcome finding at a time when there is rapidly accumulating evidence that a lack of vitamin D could be a risk factor for a number of chronic diseases,” says Cath MacDonald, independent nutritionist.

The increased selenium content of eggs is also of public health significance as UK selenium intakes have declined in recent years alongside a switch from North American to European wheat[4]. Selenium is important in protecting cellular components such as DNA, lipids and proteins against oxidation.

The new analyses reveal that an average medium egg now contains around 177mg of cholesterol, although it is now acknowledged that cholesterol in foods such as eggs does not have a significant effect on blood cholesterol in most people. All major UK heart and health advisory bodies, including the British Heart Foundation, have already removed the previous limits on egg consumption linked to their cholesterol content.

The changes are believed to be the result of improvements to hens’ feed, an increase in the ratio of white:yolk in an average egg, and improved analytical methods since the last official Government analyses were carried out in the 1980s. Vegetable oils replaced meat and bonemeal in UK hens’ feed in the 1980s and it is believed that better quality oils, together with other enhancements to hens’ feed, have improved the hens’ absorption of fat-soluble vitamins and the take-up of nutrients.

Paul Finglas, coordinator of the UK Foodcomp project at the Institute of Food Research, said: “The results from this project are important for monitoring the quality of our national diets through surveys such as the Department of Health’s National Diet and Nutrition Survey, and show the benefits of private:public partnerships working together to support new research projects.”

Tabagismo e gravidez

__

No Canadá, a década de 1990 foi marcada por um aumento da conscientização pública sobre os efeitos maléficos do tabaco sobre a saúde e pelo surgimento de estudos e leis sobre o uso e o preço dos cigarros.   

O Relatório sobre Tabagismo no Canadá revela que, de 1985 a 2001, a prevalência de fumantes diários de ambos os sexos e de todas as faixas etárias diminuiu significativamente: a população de fumantes de 15 anos ou mais diminuiu de 35,1% para 21,7% em relação à população total.

Apesar disto, os fumantes ainda são predominantemente jovens, em seus primeiros anos de vida reprodutiva. Este fato está longe de ser trivial, uma vez que a exposição crônica à fumaça de cigarros durante o período fetal aumenta significativamente o risco de problemas de saúde, físicos e mentais.

De fato, se por um lado os efeitos devastadores do tabaco sobre a saúde de adultos são bem conhecidos, seus efeitos sobre crianças estão se mostrando preocupantes, especialmente quando a exposição à fumaça do tabaco começa durante o período fetal.

Resultados do National Longitudinal Study on Children and Youth (NLSCY- Estudo Longitudinal Nacional sobre Crianças e Jovens)2 indicam que 23,3% das mulheres canadenses fumam durante a gravidez. Destas mulheres, 84% fumam durante toda a gravidez. A distribuição das taxas de uso cotidiano de tabaco entre mulheres grávidas é a seguinte: 65% fumam entre um e dez cigarros por dia; 34% fumam entre 11 e 25 cigarros; 1% fuma mais de 25 cigarros.

Uma pesquisa do CEECD* sobre percepções do uso de tabaco entre mulheres grávidas mostra que a população canadense não está consciente do número de mulheres grávidas que fumam. Apesar de haver alguma consciência pública a respeito dos efeitos maléficos do tabagismo sobre o peso de neonatos, a maioria das pessoas ainda parece desconsiderar as consequências em longo prazo da exposição do feto à fumaça do tabaco sobre a saúde física e mental das crianças.

“A protective effect of vitamin D against cancers was first proposed in 1980, based on an earlier observation that colon cancer mortality was the highest in geographical areas exposed to the least amounts of sunlight.2,3”

“Today, over 800 scientific papers have been published on the relationship between vitamin D and cancers. We now have ample evidence that maintaining adequate vitamin D levels is an effective strategy for protection against cancer.”

Vitamin D insufficiency is common among Americans overall but more prevalent among African Americans. A recent review of the literature suggests that vitamin D insufficiency is a key contributor to cancer survival disparities that exist between African Americans and white Americans (darker skin is less efficient at producing vitamin D in response to UV rays).1 A striking part of this literature review is the comprehensive summary of the existing data on vitamin D status and cancer survival: the authors present a long list of studies reporting that vitamin D adequacy is associated with reduced risk of death in all cancers combined, breast, colorectal, lung, and prostate cancer, leukemia and lymphomas.1

Several more studies of geographical variations in cancers have found the same result: inverse relationships exist between sun exposure and 24 types of cancer, including the most common cancers – those of the breast, colon, rectum, and prostate.4, 5

Since 1980, evidence for the involvement of vitamin D in the relationship between sun exposure and decreased cancer risk has progressively accumulated, as associations were found between blood vitamin D levels and reduced risk of cancers.6, 7 Further support for the importance of vitamin D in cancer prevention was provided by randomized controlled trials of vitamin D supplementation that showed reduced cancer risk compared to placebo. There have also been many reports that vitamin D receptor gene mutations, which interfere with the normal biological actions of vitamin D, were associated with increased cancer risk.8-10

Additional studies confirmed that vitamin D has growth-inhibitory effects on cells derived from breast, colon, prostate, and skin cancers.11 Vitamin D can block cancer cell growth in a number of ways: Vitamin D alters the expression of genes that regulate inflammation, cell death and cell proliferation, and also interferes with the growth-promoting actions of IGF-1 and other growth factors. Additional anti-cancer effects of vitamin D include enhanced DNA repair and immune defenses, and angiogenesis inhibition.12

Considering all of this evidence, achieving vitamin D sufficiency is so very important. Unfortunately, the Institute of Medicine is hesitant to significantly raise its vitamin D recommendations, so most multivitamins still do not contain nearly enough vitamin D (only 400 IU) to offer the security that a normal Vitamin D level will be achieved. This is an important reason why I designed my new Men’s and Women’s Daily Formula + D multivitamins to include 2000 IU of vitamin D3. In my experience, 2000 IU has been an appropriate dose to bring most people into the favorable blood 25(OH)D range of 30-50 ng/ml (I also recommend getting a blood test to confirm adequate levels). These are the only multivitamin supplements with a 2000 IU dose of D3 plus no folic acid, beta-carotene, copper, and vitamin A. This enables most people to get everything they need without needing to take multiple different products. For extra assurance, I’ve also utilized Vitamin D3 because of its highest biological value thus offering the most protection, which also is most effective for raising 25(OH)D levels.13 My goal is to make it as easy as possible to maintain healthy vitamin D levels, with plenty of D3 in a multivitamin which also gives you everything else that is worthy of supplementing, and carefully avoiding those supplemental ingredients that are potentially harmful; so additional supplements aren’t necessary to obtain the anti-cancer and bone-protective benefits of vitamin D and the other recommended nutrients.

A new study published this month finds that the hormonally active form of vitamin D, Calcitriol 1,25-dihydroxyvitamin D(3), inhibits the growth of many kinds of cancerous cells, including breast cancer, indicating that vitamin D3 can be useful in treating and even preventing a variety of cancers. Authors of the study said that caner cell growth is inhibited by “anticancer actions including cell cycle arrest, promotion of apoptosis and inhibition of invasion, metastasis, and angiogenesis.” Vitamin D’s anti-inflammatory properties and interference with estrogen synthesis further explains its anti-tumor properties.

Two studies from 2007 used meta-analysis, which combines data from multiple reports, to find that therapeutic doses of vitamin D could prevent up to half of all cases of breast cancer, and two-thirds of all cases of colorectal cancer in the United States. The studies showed a direct correlation between blood levels of vitamin D and cancer. Those with the highest blood levels were found to be at the lowest risk, and the lowest blood levels at the highest risk.

Many sources still try to cast a shadow on the effectiveness of vitamin D, citing that a specific dose strength has not yet been established, and needs more research. It likely won’t be narrowed down to a one-size-fits-all dose, because every body is different, and if it were, it wouldn’t be as effective. One other thing that may be giving varied results regarding dosing is the source of vitamin D used – it varies from study to study. Typically, higher doses are required of synthetic sources to increase blood levels, and they don’t generally have the same effect as natural sources.

The “sunshine” vitamin, vitamin D is fat-soluble vitamin required for the absorption and utilization of calcium and phosphorous. It protects against muscle weakness, regulates heartbeat, is necessary for normal blood clotting and thyroid function, and regulates more than 2,000 genes, affecting the proliferation and death of cells.

Vitamin D comes in several forms. The kind that comes from food is D2. There is a synthetic form, D5. The most active is the most natural kind, D3. It is synthesized in the skin in response to the sun’s ultraviolet rays. There is a cholesterol compound in the skin that is a precursor of vitamin D. The D we get from food and supplements is not fully active until it goes through the liver and kidneys, where it is converted, then it circulates through the blood like a hormone.

According to Bach, problems from deficiency may include: heart disease, birth defects, depression, hypertension, stroke, dementia, fibromyalgia, impaired bone mineralization, skin, breast, prostate and other cancers, multiple sclerosis, insomnia, eye problems, problems with pregnancy, and other chronic diseases. It is estimated that more than one billion people worldwide, and 77 percent of Americans, are deficient in vitamin D.

It is not possible for most people to consume enough vitamin D thorough diet alone. It is found in fatty saltwater fish and fish liver oils, such as halibut, salmon, sardines, and cod liver oil. It is also added (fortified) to diary and eggs, so you’ll find it in things like milk, yogurt, and butter. Other foods that have vitamin D include dandelion greens, oatmeal, cereals, and sweet potatoes.

Having a healthy and balanced diet can prevent cancer, and the need for prescriptions that contribute to cancer, such as cholesterol reducing drugs that inhibit vitamin D absorption from the sun. Even the National Cancer Institute estimates that 80 percent of cancer cases could be prevented. Most people supplement to get enough vitamin D. The recommended doses are generally not enough to address health problems. Be sure your supplements come from whole food vitamins so that higher doses won’t be detrimental to your health, as they might from synthetic vitamin sources.

Eating good food, limiting unhealthy food and substances, getting exercise, and soaking up a bit of sun are critical to happiness and lasting health. So get out there and have fun – and help prevent cancer while you’re at it!

Abstract

Rationale: Vitamin D insufficiency (a serum 25(OH)D <30 ng/ml) has been associated with severe asthma exacerbations, but this could be explained by underlying racial ancestry or disease severity. Little is known about vitamin D and asthma in Puerto Ricans.

Objectives: To examine whether vitamin D insufficiency is associated with severe asthma exacerbations in Puerto Rican children, independently of racial ancestry, atopy, and time outdoors.

Methods: A cross-sectional study was conducted of 560 children ages 6–14 years with (n = 287) and without (n = 273) asthma in San Juan, Puerto Rico. We measured plasma vitamin D and estimated the percentage of African racial ancestry among participants using genome-wide genotypic data. We tested whether vitamin D insufficiency is associated with severe asthma exacerbations, lung function, or atopy (greater than or equal to one positive IgE to allergens) using logistic or linear regression. Multivariate models were adjusted for African ancestry, time outdoors, atopy, and other covariates.

Measurements and Main Results: Vitamin D insufficiency was common in children with (44%) and without (47%) asthma. In multivariate analyses, vitamin D insufficiency was associated with higher odds of greater than or equal to one severe asthma exacerbation in the prior year (odds ratio [OR], 2.6; 95% confidence interval [CI], 1.5–4.9; P = 0.001) and atopy, and a lower FEV1/FVC in cases. After stratification by atopy, the magnitude of the association between vitamin D insufficiency and severe exacerbations was greater in nonatopic (OR, 6.2; 95% CI, 2–21.6; P = 0.002) than in atopic (OR, 2; 95% CI, 1–4.1; P = 0.04) cases.

Conclusions: Vitamin D insufficiency is associated with severe asthma exacerbations in Puerto Rican children, independently of racial ancestry, atopy, or markers of disease severity or control.

Laboratório vai pagar indenização recorde nos EUA

GlaxoSmithKline

__

O laboratório britânico GlaxoSmithKline (GSK), um dos maiores da indústria farmacêutica, admitirá sua culpa em processos criminais e civis abertos pelo Departamento de Justiça e por governos estaduais americanos e concordará em pagar o valor recorde de US$ 3 bilhões de indenização por fraudes. Os processos envolvem irregularidades em três medicamentos: os antidepressivos Paxil e Wellbutrin; e o Avandia, usado no tratamento de diabete.

O governo americano alega que a GSK promoveu a prescrição do antidepressivo Paxil para pacientes menores de 18 anos sem ter a devida aprovação das autoridades pediátricas da FDA, a agência federal que regula o setor de alimentos e drogas no país. O laboratório também teria cometido irregularidades na rotulação do antidepressivo Wellbutrin e deixado de informar aos usuários do Avandia, de maneira destacada na sua embalagem, os riscos de o remédio provocar ataque cardíaco.

Segundo o Departamento de Justiça, o acordo com a GSK foi o maior da história americana envolvendo irregularidades na área de saúde. O valor é também o mais expressivo envolvendo um laboratório farmacêutico no país. A empresa deverá declarar-se culpada nos tribunais que tratam, separadamente, dos três casos.

Antes da GSK, o recorde estava nas mãos da Pfizer, que fechara um acordo com o governo americano em 2009 para pagar US$ 2,3 bilhões por irregularidades na promoção do analgésico Bextra. “Em nome da GSK, quero expressar o nosso pesar e reiterar que temos aprendido com os erros cometidos. Estamos profundamente empenhados em fazer tudo o que pudermos para fazer jus e até superar as expectativas das pessoas com quem trabalhamos e servimos”, afirmou o presidente da empresa, sir Andrew Witty, ao atribuir os problemas à administração anterior.

Compromisso

A empresa, entretanto, não admitiu as alegações de irregularidades na venda e divulgação nem na definição de preços nominais do Avandia e de sete outros medicamentos – Lamictal, Zofran, Imitrex, Lotronex, Flovent, Valtrex e Advair. Esses casos também estão apontados nos processos criminais e civis.

De acordo com o vice-procurador-geral dos Estados Unidos, James Cole, o acordo multibilionário não tem precedentes e responde ao compromisso do governo americano de fazer os responsáveis por fraudes na área de saúde pagar pelos seus erros. “Em todos os níveis, nós estamos determinados a parar com práticas que ameaçam a saúde dos pacientes, prejudicam os contribuintes e violam a confiança pública”, disse Cole.
