Trans fats, but not saturated fats, linked to greater risk of death and heart disease

Higher trans fat intake associated with 20-30% increased risk, say researchers

Saturated fats are not associated with an increased risk of death, heart disease, stroke, or type 2 diabetes, finds a study published in The BMJ this week. However, the findings show that trans fats are associated with greater risk of death and coronary heart disease.
The study confirms previous suggestions that industrially produced trans fats might increase the risk of coronary heart disease and calls for a careful review of dietary guidelines for these nutrients.
Guidelines currently recommend that saturated fats are limited to less than 10%, and trans fats to less than 1% of energy to reduce risk of heart disease and stroke.
Saturated fats come mainly from animal products, such as butter, cows' milk, meat, salmon and egg yolks, and some plant products such as chocolate and palm oils. Trans unsaturated fats (trans fats) are mainly produced industrially from plant oils (a process known as hydrogenation) for use in margarine, snack foods and packaged baked goods.
Contrary to prevailing dietary advice, a recent evidence review found no excess cardiovascular risk associated with intake of saturated fat. In contrast, research suggests that industrial trans fats may increase the risk of coronary heart disease.
To help clarify these controversies, researchers in Canada analysed the results of observational studies assessing the association between saturated and/or trans fats and health outcomes in adults.
Study design and quality were taken into account to minimise bias, and the certainty of associations were assessed using a recognised scoring method.
The team found no clear association between higher intake of saturated fats and all cause mortality, coronary heart disease (CHD), cardiovascular disease (CVD), ischemic stroke or type 2 diabetes, but could not, with confidence, rule out increased risk for CHD death. They did not find evidence that diets higher in saturated fat reduce cardiovascular risk.
However, consumption of industrial trans fats was associated with a 34% increase in all cause mortality, a 28% increased risk of CHD mortality, and a 21% increase in the risk of CHD.
Inconsistencies in the included studies meant that the researchers could not confirm an association between trans fats and type 2 diabetes. And they found no clear association between trans fats and ischemic stroke.
The researchers point out that the certainty of associations between saturated fat and all outcomes was "very low," which means that further research is very likely to have an important impact on our understanding of the association of saturated fats with disease. The certainty of associations of trans fat with CHD outcomes was "moderate" and "very low" to "low" for other associations.
They also stress that their results are based on observational studies, so no definitive conclusions can be drawn about cause and effect. However, they say their analysis "confirms the findings of five previous systematic reviews of saturated and trans fats and CHD."
And they conclude that dietary guidelines for saturated and trans fatty acids "must carefully consider the effect of replacement nutrients."

Regular consumption of spicy foods linked to lower risk of death

Data suggests most benefit from eating spices regularly throughout the week
Eating spicy food more frequently as part of a daily diet is associated with a lower risk of death, suggests a new study published in The BMJ this week. The association was also found for deaths from certain conditions such as cancer, and ischaemic heart and respiratory diseases.
This is an observational study so no definitive conclusions can be drawn about cause and effect, but the authors call for more research that may "lead to updated dietary recommendations and development of functional foods."
Previous research has suggested that beneficial effects of spices and their bioactive ingredient, capsaicin, include anti-obesity, antioxidant, anti-inflammation and anticancer properties.
So an international team led by researchers at the Chinese Academy of Medical Sciences examined the association between consumption of spicy foods as part of a daily diet and the total risk and causes of death.
They undertook a prospective study of 487,375 participants, aged 30-79 years, from the China Kadoorie Biobank. Participants were enrolled between 2004-2008 and followed up for morbidities and mortality.
All participants completed a questionnaire about their general health, physical measurements, and consumption of spicy foods, and red meat, vegetable and alcohol.
Participants with a history of cancer, heart disease, and stroke were excluded from the study, and factors such as age, marital status, level of education, and physical activity were accounted for.
During a median follow-up of 7.2 years, there were 20,224 deaths.
Compared with participants who ate spicy foods less than once a week, those who consumed spicy foods 1 or 2 days a week were at a 10% reduced risk of death (hazard ratios for death was 0.90). And those who ate spicy foods 3 to 5 and 6 or 7 days a week were at a 14% reduced risk of death (hazard ratios for death 0.86, and 0.86 respectively).*
In other words, participants who ate spicy foods almost every day had a relative 14% lower risk of death compared to those who consumed spicy foods less than once a week.
The association was similar in both men and women, and was stronger in those who did not consume alcohol.
Frequent consumption of spicy foods was also linked to a lower risk of death from cancer, and ischaemic heart and respiratory system diseases, and this was more evident in women than men.
Fresh and dried chilli peppers were the most commonly used spices in those who reported eating spicy foods weekly, and further analysis showed those who consumed fresh chilli tended to have a lower risk of death from cancer, ischaemic heart disease, and diabetes.
Some of the bioactive ingredients are likely to drive this association, the authors explain, adding that fresh chilli is richer in capsaicin, vitamin C, and other nutrients. But they caution against linking any of these with lowering the risk of death.
Should people eat spicy food to improve health? In an accompanying editorial, Nita Forouhi from the University of Cambridge says it is too early to tell, and calls for more research to test whether these associations are the direct result of spicy food intake or whether this is a marker for other dietary or lifestyle factors.
* A hazard ratio is a measure of how often a particular event happens in one group compared to how often it happens in another group, over time.

Sitting May Be Linked To Increased Blood Sugar, Cholesterol Levels

AFP-Relaxnews (8/1) reported that “being healthier may be found in something as simple as standing more and sitting less at work, said astudy” published in the European Heart Journal.
        HealthDay (8/1, Reinberg) reported that investigators “found that an extra two hours per day spent standing rather than sitting was associated with approximately 2 percent lower blood sugar levels and 11 percent lower average triglycerides.” The study also indicated that “more standing time was also associated with an increase in HDL...cholesterol and a drop in LDL...cholesterol.”
        MedPage Today (8/1, Brown) reported that “the associations of sitting with fasting glucose and lipids were independent of moderate to vigorous physical activity, according to the” investigators.7

Fine Particulate Matter Not As Dangerous As EPA Claims

Writing in his column for the Washington Times (7/20), JunkScience editor Steve Milloy argues that fine particulate matter, the pollutant that is often used by the EPA to justify regulations as its reduction is claimed to significantly improve premature mortality rates, is not as dangerous as the agency considers it to be. He addresses the scientific studies behind the EPA’s recommendations and criticizes their lack of transparency and accountability to opposing conclusions.

Opposition To Larger Health Warnings Grows In India

The Deccan (IND) Herald (7/30) reports that opposition to health warnings covering 85% of tobacco packages in India has expanded from the tobacco industry to include 13 petitions from groups such as the CII (Confederation of Indian Industry) and ASSOCHAM (Associated Chambers of Commerce Of India) while no major hospitals have supported the measure. The piece notes that 26 petitions support larger warnings, however, as the Lok Sabha Committee on Subordinate Legislation prepares to issue a report on the matter to the House.

Cancer Patients Who Do Rehabilitation Prior To Treatment May Recover More Quickly, Some Specialists Say

The Kaiser Health News (7/29, Andrews) reports that “cancer patients who do rehabilitation before they begin treatment may recover more quickly from surgery, chemotherapy or radiation, some cancer specialists say.” However, “insurance coverage for cancer ‘prehabilitation,’ as it’s called, can be spotty, especially if the aim is to prevent problems rather than treat existing ones.

The power of prayer..

Dr. Mark, a well-known cancer specialist, was once on his way to an important conference in another city where he was going to be granted an award in the field of medical research.
He was very excited to attend the conference and was desperate to reach as soon as possible. He had worked long and hard on his research and felt his efforts deserved the award he was about to obtain.
However, two hours after the plane took off, the plane made an emergency landing at the nearest airport due to some technical snag. Afraid, that he wouldn't make it in time for the conference, Dr. Mark immediately went to the reception and found that the next flight to the destination was after ten hours. The receptionist suggested him, to rent a car and drive himself down to the conference city which was only four hours away.
Having no other choice, he agreed to the idea despite his hatred for driving long distances.
Dr. Mark rented a car and started his journey. However, soon after he left, the weather suddenly changed and a heavy storm began. The pouring rain made it very difficult for him to see and he missed a turn he was supposed to take.
After two hours of driving, he was convinced he was lost. Driving in the heavy rain on a deserted road, feeling hungry and tired, he frantically began to look for any sign of civilization. After some time, he finally came across a small tattered house. Desperate, he got out of the car and knocked on the door. A beautiful lady opened the door. He explained the matter and asked her if he could use her telephone.
However, the lady told him that she doesn't have a phone or any electronic gadget but told the doctor to come inside and wait till the weather improved.
Hungry, wet and exhausted, the doctor accepted her kind offer and walked in. The lady gave him hot tea and something to eat. The lady told him that he can join her for prayer. But, Dr. Mark smiled and said that he believed in hard work only and told her to continue with her prayers.
Sitting on the table and sipping the tea, the doctor watched the woman in the dim light of candles as she prayed next to what appeared to be a small baby crib.
Every time she finished a prayer, she would start another one. Feeling that the woman might be in need of help, the doctor seized the opportunity to speak as soon as she finished her prayers. The doctor asked her what exactly she wanted from the God and enquired if she thought God will ever listen to her prayers. He further asked about the small child in the crib for whom she was apparently praying. The lady gave a sad smile and said that the child in the crib is her son who is suffering from a rare type of cancer and there is only one doctor Mark who can cure him but she doesn't have money to afford his fee and moreover Dr Mark lives in another far off town. She said that God has not answered her prayer so far but said that God will create some way out one day and added that she will not allow her fears to overcome her faith.
Stunned and speechless Dr Mark was in tears which were rolling down his cheeks. He whispered, God is great and recollected the sequence of events. ....there was malfunction in the plane, a thunderstorm hit, and he lost his way; and all of this happened because God did not just answer her prayer but also gave him a chance to come out of materialistic world and give some time to the poor hapless people who have nothing but rich prayers.
Always be prepared to do .......
What God has prepared you for
" There are No Accidents in Life"
"NOTHING HAPPENS BY CHANCE " "EVERY INCIDENT IS WELL PLANNED BY THE LORD"
