Masculinity plays an important role in dealing with problems such as depression. Men often don’t feel able to reach out for assistance because both the symptoms of depression and the act of seeking help goes against a stereotypical view of how us blokes should or shouldn’t behave.
by Martha Burge. Graphic images on TV, the stench of exhaust fumes, fluorescent lighting, office temperatures that are too hot or too cold, or sitting for too long in traffic can all cause enough discomfort to make you tense against the pain to come, real or anticipated.
by Peter Bane. Botanicals can be incorporated into wines, cordials or teas, used in cooking and made into tinctures or salves. Some are applied topically as a poultice. Some plants we dry and use as teas or decoctions.
A recent survey suggests that yoga can be a substantial help for people with bipolar disorder, though the practice isn’t without risks. “There is no scientific literature on hatha yoga for bipolar disorder,” says lead author Lisa Uebelacker, associate professor (research) of psychiatry and human behavior...
by Alan Cohen. Ho’oponopo teaches that if we intend to make changes in the outer world, we must first restore balance and clarity in our own mind and heart. So Dr. Hew Len regularly took each patient in mind, and spoke to their spirit: “I’m sorry for..."
In the time that it will take you to read this article, millions of your body’s cells will have died via a self-destruct mechanism known as programmed cell death. This process is part of your body’s normal healthy function and is used to eliminate cells that are no longer needed or which have been damaged...
It’s no secret that yoga can aid mental well-being. What is more, it can help soldiers suffering from post-traumatic stress disorder, according to new research.
Both rats and humans are omnivores, and both use flavour conditioning – learning through taste and experience which foods are good to eat and which to avoid. So if a particular flavour is associated with a desirable outcome like feeling full, this makes it more palatable, whereas a stomach illness would make it unpalatable.
Today, chemicals comprise the backbone of our modern lifestyle and are the largest sector of our economy. We generate 300 billion pounds of synthetic chemicals each year in the U.S. alone, and an average American uses more than 1,500 pounds of chemical products. Synthetic chemicals are poisoning our bodies from the moment of conception. What are we going to do about it?
Ginseng, the root of the plant Panax ginseng, is one of the most commonly used herbal medicines and is often sold as an over-the-counter remedy for fatigue. Although it has been used by humans for thousands of years, more recent research has begun to investigate therapeutic and pharmacological uses including anti-allergy and anti-inflammatory properties.
by Marla Paul. Mindfulness training eases depression and improves sleep and quality of life for both people with early-stage dementia and their caregivers, research shows.
by Kat Duff. We are too awake, rather than not sleepy enough. The result, combined with a genetic propensity toward anxiety, makes for a chronic insomniac. While most of us who struggle with sleep fall short of that label, I suspect the same...
Have you ever tried to grow your favorite summer vegetable or garden herb and something went wrong? Maybe it was poor planting, a disease, or a pesky insect. Maybe you need to troubleshoot problems or want definitive answers to questions like when to plant for your area or exactly when to fertilize.
by Sharron Murray, MS, RN. In Traditional Chinese Medicine, it is believed that certain conditions are necessary for disease and disharmony to occur. Good health is dependent upon the smooth flow of chi, the balance of yin and yang, the influences of the five phases, and the balance between our organ network systems and our external environment.
Being proud about weight loss may play a role in eating disorders like anorexia nervosa. The condition has a death rate 12 times higher for young women between the ages of 15 and 24 than all other causes of death combined.
As many as 250,000 US veterans of the 1990-91 Gulf War suffer from symptoms of a disorder that is likely caused by exposure to toxins, such as nerve gas.
Sleep – elusive, precious, restful sleep – is a topic close of many of our hearts. Such is the importance of this activity that sometimes people cling on to half-baked ideas about it with an unnatural fervour.
Instead of having to choose between healthy and unhealthy food options, a “vice-virtue” combination could satisfy both impulses, say researchers.
Sports performance was once thought to be enhanced by practices such as drinking cognac before an Olympic marathon run. Thankfully, today’s nutrition strategies are more scientific and properly researched.
We now know quite a lot about when and what to eat before, during, and after exercise for better performance. Of course, what you eat at all these points plays a role but what you eat to recover after exercise (recovery nutrition) supports the body’s physiological adaptation to the demands of training and competition. And it prepares the body for the next event.
It replenishes fuel stores in muscles and the liver, minimises muscle loss and encourages muscle growth and repair, minimises fatigue and injury, and supports immune function. Replenishing fluid is also vital but outside the scope of this article.
Re-fuelling after exercise is important for maintaining adequate energy stores for beneficial changes in your muscles (training adaption). But it shouldn’t be in excess of the metabolic demands of what you’ve done if you want to maintain appropriate weight, body composition and support performance goals.
Training and competition require energy, and the energy muscles use is supplied by a mix of fuels in different proportions depending on the intensity and duration of exercise. In general terms, carbohydrates are the primary fuel source as exercise intensity increases.
The type of carbohydrate used by the body as fuel for exercise is glucose. Consuming carbohydrates before and during prolonged exercise (such as a marathon run) will replenish glucose, delay the onset of fatigue, and allow you to compete for a longer period of time.
Glucose is stored in the muscles and liver as glycogen, and research shows low muscle glycogen can impair performance. Depending on when the last carbohydrate meal was consumed, glycogen reserves can be depleted after about 60 to 90 minutes of intense exercise.
Planning for glycogen replacement requires adjusting for variations in exercise intensity and duration, the amount of muscle you have, your training goals, and dietary intake at other times, including before and during events. So total carbohydrate targets can vary considerably.

Post-exercise carbohydrate recommendations for athletes generally suggest consuming about 1.2 grams of carbohydrate for each kilogram of body weight within an hour of completion, and each hour for four hours after activity. This should be followed by regular carbohydrate intake appropriate to meet daily requirements.
But there are also other things you’re going to need to recover properly. What you generally eat and the type of exercise you do can both affect the synthesis of protein in your muscles.
Physical training is a stimulus for muscle growth and adaptation. Hard-working muscles come under stress during physical activity, and the body’s limited reserves of amino acids (what proteins are made from) become rapidly depleted.
Consuming protein or amino acids after exercise can reduce muscle breakdown and encourage new tissue growth. But here again, individual responses and requirements can vary quite a lot.
The type and amount of your protein intake both play a role in muscle reconditioning after exercise, with some evidence suggesting that dairy proteins, such as whey protein, may offer advantages over other sources.
But studies are not consistent about ideal timing. Some suggest consumption before exercise while others recommend consumption within 24 hours of completion offers most benefit.
Generally speaking, consuming 20 to 25 grams of quality protein as soon as possible after exercise is recommended for building muscle and help reconditioning. Another recommendation is around 0.25 to 0.3 grams protein per kilogram of body mass.
It follows that foods containing both carbohydrates and protein are generally recommended as being best for recovery. And there are other advantages – consuming protein with carbohydrates may improve glycogen replenishment and reduce muscle breakdown. The optimal carbohydrate to protein ratio for glycogen replenishment is three to one.

In general, moderate to high glycaemic index, low-fibre carbohydrate sources are preferable because they’re digested and absorbed rapidly. And good quality plant- or animal-derived protein foods are better because they contain essential amino acids.
The average person exercising at low to moderate intensities for around 30 minutes a day on most days of the week, should follow general dietary guidelines to meet their energy and nutritional needs.
But it’s worthwhile trying to adjust mealtimes to coincide with recommended post-workout time (30 to 90 minutes) for eating. Adding an extra recovery meal, or a high-sugar sports drink, will merely increase your risk of consuming more than you need.
Specialised nutrition plans are particularly useful for highly active and trained people who engage in moderate to high intensity activity for between two and six hours every day most days of the week.
Energy requirements increase at this level and carefully planned nutrient intake and timing will support performance while minimising fatigue and injury.
Here are a few examples of foods that may support an athlete’s recovery eating plan, containing protein, as well as approximately 50 grams of carbohydrate:
The most important thing to remember is that there is no one size that fits all. Individual nutrition plans are best developed with the help of qualified sports nutrition experts and may involve some trial and error for the best outcome.
