Guess what scientists have discovered
So, you go to the gym regularly, follow all the latest exercises trends, but are still not getting the results you wanted. It’s frustrating isn’t it. You want that sculptured body, but it seems elusive. Well helps may be coming. Until now scientists haven’t been fully able to understand how muscle responds to exercise especially in the early stages of an exercises program – when we are tempted to give up because we aren’t yet seeing the results.
Scientists at Liverpool John Moores University (LJMU) and the Australian Catholic University in Melbourne have established a new technique for studying muscle growth in humans. The technique, termed Dynamic Proteome Profiling, provides comprehensive coverage of the early changes that occur within human muscle in response to exercise training. This was the first data on the rate at which new muscle proteins are made when volunteers performed strength training exercises.
Muscle is composed of thousands of different proteins and each protein makes a specific contribution to muscle function, for example, some proteins are responsible for movement while others are required to provide energy. The proteins in muscle have a tough time and often become damaged, but in healthy cells a sophisticated recycling system keeps protein quality high by continually breaking down and remaking each protein. When muscle fibres grow in response to weight training the amount of specific proteins is increased, and therefore muscle becomes larger and stronger.
Because of Dynamic Proteome Profiling, scientists are now able to identify exactly which proteins are most responsive to exercise and whether that response is due to more of the protein being made or less of the protein being degraded/ broken down by the cell’s recycling machinery.
This profiling will allow a finer level of detail of muscle response to exercises which could lead to better training methods, nutritional strategies or medicines that can be used to promote muscle growth, and hopefully less frustration on getting the results from hours spent in the gym!

Natural ways to boost fertility through diet
In my previous post, I shared tips on how to change your lifestyle to boost your fertility. In this post, I wanted to share some tips on nutrition to boost your fertility based on scientific evidence. 1. Take a multivitamin Women who take a daily multivitamin take 5% less time to conceive than those taking a placebo. 2. Supplementation Take supplementation to correct any nutritional deficiencies. A study showed that magnesium deficiency is associated with female, infertility, increased miscarriage rates, and increased incidences of premature and low-birth-weight babies. When magnesium supplements were given for four months to six magnesium deficient women with unexplained infertility, all six conceived within the following eight month and produced healthy babies. In men, low levels of zinc have been linked to poor sperm quality and infertility. 3. Optimise your diet. Researchers found that an optimal diet for fertility was one with:
- a lower intake of trans fats with a greater intake of monounsaturated fats (found in olive oil, avocados and nuts)
- a lower intake of animal protein with a greater intake of vegatable protein (found in peas, lentils and beans)
- a greater intake of plant-based iron (from sources like whole grains, leafy green vegatables, nuts and seeds)
- a preference for high-fat diary products (like full-fat cheese and milk)
Can tackling the big questions in life make you less depressed and anxious?
Mixed anxiety & depression is the most common mental disorder in Britain,and it estimates to cause one fifth of days off from work. Well according to researches if you prepared to tackle big questions in life e.g.
- Is there a God?
- Does life have a purpose?
Natural remedies for the winter blues – Part 1
By January I am seriously missing the sun. While I know we have had the shortest day, the grey weather and the snow jsut reminds me we are in deep winter. So with the Brexit impass being deeply demoralising and frustraing, I wanted to share some tips to combat the blues. 1. Vitamin D Most people are short of Vitamin D in the uk. One of the signs of being short of Vitamin D is feeling blue. 2. Spice it up. Earlier today I was planning my meals for the week before I went to the supermarket. At this time of year I always fancy dishes containting yellow rice i.e. paella or pilau rice. I know its the yellow colour that particularly appeals which you get by adding either Tumeric or Saffron. In clinical trails Curcumin the main active ingredient in Tumeric (the bright yellow Indian spice) has been to be as effective as Prozac. A review of several trains of Saffron found it was a safe and effective treatmetn for depression. While I like to cook with the spices, it isn't as effective as supplements which are standardised extracts. For me cooking with the spice is fine as I am not depressed. 3. 5-HTP A naturally occuring amino acid, 5-HTP is used by the body to make serotonin the "happy hormone". Suplements produced from the seeds of the West African medicinal plant Griffonia Simplicifoia show promised for depression. References Woo YS, Kim S, Jeong JH, Jung YE, Kim MD, Bahk WM.
