Eating lean beef daily can help lower blood pressure

18.07.2014

Contrary to conventional wisdom, a growing body of evidence shows that eating lean beef can reduce risk factors for heart disease, according to recent research by nutritional scientists.

"This research adds to the significant evidence, including work previously done in our lab, that supports lean beef's role in a heart-healthy diet," said Penny M. Kris-Etherton, Distinguished Professor of Nutrition, Penn State. "This study shows that nutrient-rich lean beef can be included as part of a heart-healthy diet that reduces blood pressure, which can help lower the risk for cardiovascular disease."

The DASH eating plan -- Dietary Approaches to Stop Hypertension -- is currently recommended by the American Heart Association to lower blood pressure and reduce risk of heart disease. People following the DASH diet are encouraged to eat fruits, vegetables, low-fat dairy and protein predominantly from plant sources.

Lean beef can be enjoyed as the predominant protein source in a DASH-like diet, along with fruits, vegetables and low-fat dairy, to effectively help lower blood pressure in healthy individuals, the researchers report in the Journal of Human Hypertension. This DASH-like diet is also called the BOLD+ diet -- Beef in an Optimal Lean Diet plus additional protein.

Kris-Etherton and colleagues tested four diets to find the effects on vascular health. The diets tested included the Healthy American Diet -- which served as the control -- the BOLD+ diet, the BOLD diet and the DASH diet.

The control diet consisted of 0.7 ounces of lean beef per day, while the DASH diet included 1.0 ounce. The BOLD diet had 4.0 ounces and the BOLD+ diet included 5.4 ounces of lean beef.

The researchers tested the four different diets with 36 participants, between the ages of 30 and 65. All participants followed each diet at different times throughout the study period. Subjects were randomly assigned an order to follow each of the four diet plans for five weeks each, with a break of one week in between each new plan. Blood pressure was taken at the beginning and end of each diet period.

The BOLD+ diet was more effective at reducing blood pressure when compared to the other diets tested.

"This evidence suggests that it is the total protein intake -- not the type of protein -- that is instrumental in reducing blood pressure, as part of a DASH-like dietary pattern," the researchers stated.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
