Mediterranean diet and regular exercise prevent death

Categories: Diet research

Eating a Mediterranean diet reduces the risk of death from all causes, including cardiovascular disease and cancer. Researchers assessed conformity with the Mediterranean diet in 380,296 of the participants of the NIH-AARP Diet and Health Study, with no history of chronic disease. Components of the diet included vegetables, legumes, fruits, nuts, whole grains, fish, alcohol and meat, and a high ra ...

High meat intake linked to cancer

Categories: Diet research

Data from a very large US health study are providing convincing information on the links between various diet and lifestyle factors and a variety of diseases. Researchers used data from a cohort study, which began in 1995 (the National Institutes of Health-American Association for Retired Persons (NIH-AARP) Diet and Health Study) and involves approximately 500,000 men and women aged 50-71 at basel ...

Honey better than drugs for kids night-time coughs

Categories: Diet research

Honey is more effective at soothing children's night-time coughs than over-the-counter antitussive medication. An American study of 105 children aged 2-18 years compared the effects of a single nocturnal dose of buckwheat honey or honey-flavoured dextromethorphan (DXM) with no treatment, on nocturnal cough and sleep difficulty associated with childhood upper respiratory tract infections. Significa ...

Obesity linked with cancer risk

Categories: Diet research

Being overweight increases the risk of developing many forms of cancer. A meta-analysis by UK researchers combined data from 221 studies, including over 250,000 cases of cancer, to determine the risk of cancer associated with a 5kg/m2 increase in body mass index (BMI). The researchers found that in men, a 5kg/m2 increase in BMI raised the risk of oesophageal adenocarcinoma by 52%, thyroid cancer b ...

Eat three meals a day

Categories: Diet research

Eating regular meals is better for health than eating one large meal a day. In a crossover study carried out in the USA, a small group of volunteers participated in two eight-week meal-treatment periods, consuming either all their required weight-maintenance calories in one meal or in three meals a day. At the end of the eight-week study period, the groups swapped over, therefore acting as their o ...

Vitamin D protects against heart disease and cancer

Categories: Diet research

Vitamin D deficiency is already known to be associated with osteoporosis, now two new studies suggest that it may also be associated with heart disease and poorer prognosis for some cancers. A US cohort study of 1739 people with no cardiovascular disease at baseline, showed that those with low blood concentrations of vitamin D had twice the risk of a first cardiovascular event, such as a heart att ...

Caffeine and miscarriage

Categories: Diet research

Too much caffeine during pregnancy may double the risk of miscarriage. In an American cohort study, 1,063 pregnant women were interviewed about their caffeine intake. An increasing dose of daily caffeine during pregnancy was associated with an increased risk of miscarriage, compared with no caffeine intake. Of 264 women who had consumed no caffeine, 12.5% had miscarriages. The miscarriage rate was ...

Apples and fish during pregnancy protect against atopy

Categories: Diet research, Allergies

Intake of apples and fish by women during pregnancy may reduce the risk of their children developing atopic conditions, according to the results of a longitudinal cohort study of nearly 2000 Dutch children. Mothers completed a food frequency questionnaire (FFQ) during pregnancy, and children in the cohort were followed up at five years of age with a symptom questionnaire and FFQ. Food groups analy ...

Diet improves fertility

Categories: Diet research

Following a 'fertility diet' may favourably influence fertility in otherwise healthy women. A cohort of 17,544 American women, without a history of infertility, were followed for eight years as they tried to become pregnant. Researchers calculated a dietary score of one to five points for each woman, based on factors previously associated with reduced ovulatory infertility (higher consumption of m ...

Echinacea prevents and treats colds

Categories: Diet research

A new meta-analysis suggests that taking Echinacea can cut the chances of catching the common cold by 58% and reduce its duration by 1.4 days. American researchers combined the results of 14 randomised, placebo-controlled clinical trials involving nearly 3000 patients, making it the largest meta-analysis on the subject to date. The research backs up a previous study that found Echinacea to be an e ...

Fast for a healthy heart

Categories: Diet research, Geriatric

New research suggests that Mormons' habit of fasting for one day a month may benefit their hearts. A study in Utah, where the religion is based, surveyed 515 elderly people undergoing coronary angiography for suspected heart disease about their lifestyle. Those who fasted were 39% more likely than non-fasters to have a healthy heart. About 8% of those surveyed were not Mormons, and those who regul ...

Food restriction increases rats pleasure

Categories: Diet research

A brain-imaging study of genetically obese rats has added to existing evidence that dopamine, the neurotransmitter associated with reward, pleasure, movement and motivation, plays a role in obesity. Investigators found that obese rats had lower levels of dopamine receptors than lean rats. They also demonstrated that restricting food intake can increase the number of dopamine receptors, which can a ...

Eat less, stay fit

Categories: Diet research

Caloric restriction has previously been shown to extend lifespan in animal models. New research shows that it can also maintain physical fitness into old age. A study on rats that had been maintained on a severely calorically restricted diet since birth showed that they had significantly higher physical performance scores at ages comparable to 50-70 years in humans, than animals fed a normal diet. ...

Diet and diabetes

Categories: Diet research

Research into the impact of diet on diabetes is showing that a variety of nutritional interventions can help prevent or ameliorate both forms of the disease, confirming TCM theories. A meta-analysis which pooled data for six cohort studies including 286,125 participants concluded that whole grain intake is inversely associated with risk of type 2 diabetes. A two-serving-per-day increment in whole ...

Coffee may increase hypertension

Categories: Diet research, Hypertension

Coffee drinking seems to increase the risk of requiring antihypertensive drug treatment. Researchers determined daily coffee consumption via questionnaire in 24,710 Finnish subjects and observed them prospectively over 13 years. They concluded that coffee drinking was associated with a slightly increased risk of requiring antihypertensive treatment. This risk was higher in subjects with low-to-mod ...

Refined carbs are bad for the eyes

Categories: Diet research, Eye disorders

People who eat more refined carbohydrates have a higher risk for age-related macular degeneration (AMD), the retinal disease that is the leading cause of blindness. A prospective study of 4000 people, aged 55-80, in the USA examined the relationship between dietary carbohydrate quality, measured by glycaemic index (GI) and the progression of AMD. The results showed that participants who consumed t ...

Diet and dementia

Categories: Diet research

A recent article by Canadian authors highlights associations between dietary choices and risk of dementia. According to the authors, diets high in fat, especially trans and saturated fats, adversely affect cognition, while those high in fruits, vegetables, cereals and fish are associated with better cognitive function and lower dementia risk. They point out that adults with diabetes are especially ...
