กินผักผลไม้อายุยืน ยิ่งกว่ากินเนื้อสัตว์

thairath130610_002ผู้ที่กินเนื้อสัตว์แต่น้อย กินแต่ผักผลไม้เป็นหลัก มักจะไม่ค่อยเสียชีวิตภายในช่วงเวลาเฉพาะใดๆ

ดร.ไมเคิล ออลิช หัวหน้าคณะศึกษา มหาวิทยาลัยโลมา ลินดา ในแคลิฟอร์เนีย กล่าวเปิดเผยผลการศึกษาต่อไปว่า นับเป็นหลักฐานเพิ่มเติมแสดงถึงคุณประโยชน์ของการกินมังสวิรัติ ในการช่วยป้องกันโรคเรื้อรังและทำให้อายุยืนยาว เคยมีการศึกษาก่อนหน้านี้มาก่อนว่าผู้ที่กินผักผลไม้เป็นหลักมักจะไม่ค่อยเสียชีวิตด้วยโรคหัวใจ หรือสาเหตุอื่นใดในช่วงเวลาเฉพาะใดๆ

การศึกษาครั้งใหม่ได้ทำจากข้อมูลของคนในอเมริกาจำนวน 73,308 คน เมื่อช่วงระยะเวลาระหว่าง พ.ศ.2545 และ 2550 ผลปรากฏว่า โดยรวมแล้วผู้ที่กินเนื้อสัตว์ ใน 1,000 คนในแต่ละปี จะเสียชีวิตลง 7 คน ในขณะที่ผู้ที่กินผักผลไม้ส่วนใหญ่ ใน 1,000 คน จะเสียชีวิตลงแค่ 5-6 คน โดยเฉพาะเพศชาย จะเป็นผู้ได้ประโยชน์สูงสุดจากการกินผักผลไม้.

The health benefits of eating low-fat diets based on vegetables, whole grains and fruit include lower blood pressure and improved cholesterol levels

The health benefits of eating low-fat diets based on vegetables, whole grains and fruit include lower blood pressure and improved cholesterol levels

Are vegetarian diets secret to long life? People who avoid meat have better health due to lower blood pressure

  • Study shows vegetarians 12% less likely to die than meat-eaters
  • Ingredients in red meat linked to increased risk of cancer and high blood pressure
  • Vegetarians more likely to drink less, smoke less and exercise more

Vegetarians live longer because of their diet – with men reaping the most benefits, claim researchers.

They found a cut in death rates for people eating vegetarian diets compared with non-vegetarians in a study of more than 70,000 people.

Over a six-year period, vegetarians were 12 per cent less likely to die from any cause, says a report published Online First by JAMA Internal Medicine.

It is thought the benefits come from lower blood pressure and improved cholesterol levels in people eating low-fat diets based on vegetables, whole grains and fruit.

Vegetarian diets have been linked to lower risk for several chronic diseases, including high blood pressure, metabolic syndrome, diabetes and heart disease.

An estimated three million Britons, around five per cent, are vegetarian and never eat meat or fish, including superstar musician Paul McCartney and his fashion designer daughter Stella McCartney.

Dr Michael Orlich, of Loma Linda University in California, and colleagues examined all-cause and cause-specific death rates in a group of 73,308 men and women Seventh-day Adventists.

Researchers assessed dietary patients using a questionnaire that classified them into five groups: nonvegetarian, semi-vegetarian, pesco-vegetarian (includes seafood), lacto-ovo-vegetarian (includes dairy and egg products) and vegan (excludes all animal products).

The study said vegetarian groups tended to be older, more highly educated and more likely to be married, to drink less alcohol, to smoke less, to exercise more and to be thinner.

Previous research has suggested vegetarian diets may extend life expectancy compared with meat-eating, but many of the studies have been small.

In the latest study there were 2,570 deaths among the study participants during an average follow-up time of almost six years.

There was a 12 per cent lower risk of dying from any cause for vegetarians compared with non-vegetarians.

Men fared better, as they benefited from a significant reduction in deaths from cardiovascular disease and ischaemic heart disease.

In women, there were no significant cuts in these categories of deaths.

The report said ‘These results demonstrate an overall association of vegetarian dietary patterns with lower mortality compared with the non-vegetarian dietary pattern.

‘They also demonstrate some associations with lower mortality of the pesco-vegetarian, vegan and lacto-ovo-vegetarian diets specifically compared with the non-vegetarian diet.’

The main reason for the difference is thought to be the effect of a low-fat vegetarian diet on cholesterol and blood pressure, partly through avoidance of red meat and also from higher consumption of vegetables.

Red meat, especially processed meat, contains ingredients that have been linked to increased risk of chronic diseases, such as cardiovascular disease and cancer.

These include heme iron, saturated fat, sodium, nitrites, and certain carcinogens that are formed during cooking.

Eating more vegetables and fruit may also help through their antioxidant effects, combating harmful naturally occurring chemicals in the body.

Official advice from the Department of Health in 2010 said cutting down on red meat could reduce the risk of bowel cancer.

Liz O’Neill, head of communications at the Vegetarian Society said ‘With higher intakes of fresh vegetables, pulses and other plant-foods, it seems obvious to many that balanced vegetarian diets are healthier than those reliant on meat, but we do not need to rely on gut instinct with so much hard evidence of that health advantage, both in the UK and abroad.

‘This new American study is significant because the nature of the community studied (Seventh Day Adventists) means that even the meat eaters included were leading a relatively health-conscious lifestyle.

‘The reported 12 per cent reduction in mortality was directly associated with being vegetarian, rather than having a healthy balanced diet.

‘Similarly UK studies indicate that vegetarians have lower rates of cancer and significantly lower (32 per cent less) rates of heart disease which are major causes of death in Britain.’

Findings from the largest British study of 45,000 Britons earlier this year found vegetarians have healthier hearts than people who eat meat or fish.

They were one-third less likely to need hospital treatment for heart disease or die from it.

An apple a day doesn’t just keep the doctor away: Diet rich in fruit and veg makes young people calmer and more energetic

  • Fruit and vegetables can improve your state of mind

According to nutritional wisdom, an apple a day can help keep your body healthy. Now researchers say it can also improve your state of mind.

A team from the psychology department at the University of Otago in New Zealand asked 281 young people to complete a 21-day online food diary.

At the end of the trial period, those who ate plenty of fruit and vegetables reported feeling calmer, happier and more energised. Those who ate junk food reported no difference in mood.

Head researcher Dr Tamlin Conner said: ‘On days when people ate more fruits and vegetables, they reported feeling calmer, happier and more energetic than they normally did.’

‘After further analysis we demonstrated that young people would need to consume approximately seven to eight total servings of fruits and vegetables per day to notice a meaningful positive change.

One serving of fruit or vegetables is approximately the size that could fit in your palm, or half a cup.

To understand which comes first – feeling positive or eating healthier foods – Dr Conner and her team ran additional analyses and found that eating fruits and vegetables predicted improvements in positive mood the next day, suggesting that healthy foods may improve mood.

Dr Conner added: ‘While this research shows a promising connection between healthy foods and healthy moods, further research is necessary such as the development of randomised control trials evaluating the influence of high fruit and vegetable intake on mood and well-being.’
