Study reaffirms soy-dairy protein blend increases muscle mass

Blend of high-quality proteins can prolong muscle building after resistance exercise, compared to whey alone

2014-04-25

(Press-News.org) A new study published online in the Journal of Applied Physiology shows additional benefits of consuming a blend of soy and dairy proteins after resistance exercise for building muscle mass. Researchers from the University of Texas Medical Branch found that using a protein blend of soy, casein and whey post-workout prolongs the delivery of select amino acids to the muscle for an hour longer than using whey alone. It also shows a prolonged increase in amino acid net balance across the leg muscle during early post-exercise recovery, suggesting prolonged muscle building.

The study was conducted by researchers from UTMB in collaboration with DuPont Nutrition and Health. "This study sheds new light on how unique combinations of proteins, as opposed to single protein sources, are important for muscle recovery following exercise and help extend amino acid availability, further promoting muscle growth," said Blake B. Rasmussen, chairman of UTMB's Department of Nutrition and Metabolism and lead researcher of the study.

This new research, using state-of-the-art methodology, builds on an earlier publication reporting that a soy-dairy blend extends muscle protein synthesis when compared to whey alone, as only the blended protein kept synthesis rates elevated three to five hours after exercise. Together, these studies indicate that the use of soy-dairy blends can be an effective strategy for active individuals seeking products to support muscle health.

"Because of the increased demand for high-quality protein, this study provides critical insight for the food industry as a whole, and the sports nutrition market in particular," said Greg Paul, global marketing director for DuPont Nutrition and Health. "With more and more consumers recognizing the importance of protein for their overall health and well-being, the results of this study have particular relevance to a large segment of the population, from the serious sports and fitness enthusiast to the mainstream consumer."

The double-blind, randomized clinical trial included 16 healthy subjects, ages 19 to 30, to assess if consumption of a blend of proteins with different digestion rates would prolong amino acid availability and lead to increases in muscle protein synthesis after exercise. The protein beverages provided to study subjects consisted of a soy-dairy blend (25 percent isolated DuPont Danisco SUPRO soy protein, 50 percent caseinate, 25 percent whey protein isolate) or a single protein source (whey protein isolate). Muscle biopsies were taken at baseline and up to five hours after resistance exercise. The protein sources were ingested one hour after exercise in both groups.

The study demonstrates that consuming a soy-dairy blend leads to a steady rise in amino acids, the building blocks of muscle. The data showed that the soy-dairy blend yields an increase in select amino acid delivery for about an hour longer than the use of whey protein alone. The blend also sustained a greater positive net amino acid balance than whey, suggesting there is less muscle protein breakdown during the time period shortly after consumption of a blended protein product.

Further research is ongoing to identify the long-term effect on muscle mass and strength.

Nitrogen pollution, climate and land use: Why what we eat matters

2014-04-25

A new report quantifies for the first time how much our food choices affect pollutant nitrogen emissions, climate change and land-use across Europe. The executive summary of the European Nitrogen Assessment Special Report on Nitrogen and Food, 'Nitrogen on the Table', was released today (Friday 25 April 2014). The Special report provides an assessment of what would happen if Europe were to decrease its consumption of meat and dairy products. It shows how much cutting down on meat and dairy in our diets would reduce nitrogen air and water pollution, and greenhouse gas ...

A civil war inside our cells: Scientists show how our bodies fight off 'jumping genes'

2014-04-25

ANN ARBOR, Mich. — There's a civil war going on inside every one of the 37 trillion cells in your body. Now, University of Michigan scientists have uncovered how your cells keep this war from causing too much collateral damage. On one side of the battle: your "regular" DNA, which provides the day-to-day instructions for life. On the other side: tiny bits of rogue DNA that hide like spies between genes in your own DNA. From time to time, these rogue bits of DNA spin off a copy of themselves and "jump" to another DNA location – often causing harmful mutations when they ...

Traces of recent water on Mars

2014-04-25

The southern hemisphere of Mars is home to a crater that contains very well-preserved gullies and debris flow deposits. The geomorphological attributes of these landforms provide evidence that they were formed by the action of liquid water in geologically recent time. Evidence of liquid water When sediment on a slope becomes saturated with water, the mixture may become too heavy to remain in place, leading to a flow of debris and water as a single-phase unit. This is called a debris flow. Debris flows on Earth often cause significant material destruction and even human ...

Tsetse fly genetic code sequenced

2014-04-25

Scientists at the University of Liverpool have been part of a ten-year project which has successfully sequenced the genetic code of the tsetse fly – making major advances in disease control possible. Tsetse flies are unique to Africa and can infect people bitten by them with sleeping sickness, a disease which damages the nervous system and is fatal if untreated. This kills over 250,000 people each year. Traditional methods of control such as releasing sterile males, trapping and pesticide spraying are expensive and difficult to implement. Sleeping sickness can also ...

Quantitative volumetric analysis of the optic radiation in the normal human brain

2014-04-25

The optic radiation is a dense fiber tract that emerges from the lateral geniculate nucleus and continues to the occipital visual cortex. Especially, the optic radiation is an important fiber structure that conveys visual information from the lateral geniculate nucleus to the primary visual cortex in the occipital lobe. Current studies have focused on the anatomical characteristics of optic radiation fiber tracts in individual brains and on comparisons of the anatomical characteristics of the optic radiation fiber tracts between patient and control groups. Therefore, no ...

Climate change: Don't wait until you can feel it

2014-04-25

Washington, D.C.— Despite overwhelming scientific evidence for the impending dangers of human-made climate change, policy decisions leading to substantial emissions reduction have been slow. New work from Carnegie's Katharine Ricke and Ken Caldeira focuses on the intersection between personal and global impacts. They find that even as extreme weather events influence those who experience them to support policy to address climate change, waiting for the majority of people to live through such conditions firsthand could delay meaningful action by decades. Their findings ...

Reconstructed ancient ocean reveals secrets about the origin of life

2014-04-25

HEIDELBERG, 25 April 2014 – Researchers from the University of Cambridge have published details about how the first organisms on Earth could have become metabolically active. The results, which are reported in the journal Molecular Systems Biology, permit scientists to speculate how primitive cells learned to synthesize their organic components – the molecules that form RNA, lipids and amino acids. The findings also suggest an order for the sequence of events that led to the origin of life. A reconstruction of Earth's earliest ocean in the laboratory revealed the spontaneous ...

Metabolism may have started in our early oceans before the origin of life

2014-04-25

The chemical reactions behind the formation of common metabolites in modern organisms could have formed spontaneously in the earth's early oceans, questioning the events thought to have led to the origin of life. In new research funded by the Wellcome Trust, researchers at the University of Cambridge reconstructed the chemical make-up of the earth's earliest ocean in the laboratory. The team found the spontaneous occurrence of reaction sequences which in modern organisms enable the formation of molecules essential for the synthesis of metabolites such as amino acids, ...
