Researchers at Karolinska Institutet have analysed the eating habits of 25,000 Swedish women and found two specific dietary patterns that correlate significantly with a healthy heart.
It is hardly the first time that a link has been studied between diet and the risk of cardiac arrest, for instance. What is new about this particular piece of research is that the scientists have unreservedly mapped out the women’s dietary habits instead of deciding in advance the kind of food they wanted to examine. Doing this, the researchers were able to identify two specific dietary patterns that were clearly linked to a reduced risk of cardiovascular disease.
“The first was characterised by a high consumption of vegetables and fruit, and the second by the moderate consumption of alcohol; we’re talking about the equivalent of four vegetables and two pieces of fruit a day and half a glass of wine," says Agneta Åkesson, one of the scientists behind the study.
She stresses that the dietary patterns in question included the regular consumption of wholegrain products, fish and beans. Almost one third of the women in the study showed this healthier eating behaviour, which in turn gave a 57 per cent lower risk of myocardial infarction than a diet low in these foodstuffs.
Using this dietary behaviour as a basis, the researchers added other health factors, such as a healthy body weight, abstinence from smoking, and regular exercise (by which was meant a daily walk of at least 40 minutes or a cycle ride, and one hour’s more intense training a week). All these conditions were met by only one in twenty women, who, it transpired, had a full 92 per cent lower risk of suffering a heart attack than the women who smoked, were overweight, ate unhealthy food, and were physically inactive.
“If all women lived like the healthy group, 75 per cent of heart attacks would be prevented," says Agneta Åkesson. “It’s also important to produce data based on the situation in Sweden so that we can improve public health in our country."
The newly published study was based on data from 25,000 women born in Uppsala and Västmanland County between 1914 and 1948, who have been monitored since 1997 with regard to their chances of suffering a myocardial infarction. The material is part of the Swedish Mammography Cohort. Since the study is based on healthy women, the percentage eating a wholesome diet is higher than the 20 per cent or less that would be expected amongst women in Sweden over the age of 50.Publication:

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
