How well do YOU know your food?

Test your health IQ with this quick quiz.

If you want to, you can leave your score in the comments section. It will be interesting to compare how well people REALLY know their food!


How health savvy are you?
By Melanie McGrice, Accredited Practising Dietitian

Sure you can spot an apple in a fruit line-up but let's test your knowledge with some other common foods in your diet! Try this quiz to get a really close look at the foods you're eating and see how health savvy you are! Answer each of the 10 questions TRUE or FALSE, you will get 1 point for every correct answer! Why not get your family and friends involved and try and answer the questions together. Let's have a little fun with your food!


1. Consumption of too much cola can cause osteoporosis
TRUE or FALSE


2. A slice of bread has more kilojoules than a glass of red wine
TRUE or FALSE


3. Eggs should be avoided if you have high cholesterol levels
TRUE or FALSE


4. A diet rich in omega-3 fatty acids may reduce your risk of
developing Alzheimer's disease
TRUE or FALSE


5. A high intake of aspartame artificial sweeteners is one of the
main causes of cancer in Australia
TRUE or FALSE


6. Low GI white bread is just as healthy as wholemeal bread
TRUE or FALSE


7. Full cream milk is high in fat
TRUE or FALSE


8. Margarine is high in trans fats
TRUE or FALSE


9. Most nuts contain at least 50% fat, therefore, should be avoided
by people who want to lose weight
TRUE or FALSE


10. If a product has 300mg of salt (sodium) per 100g as recorded on the nutritional label, it is considered to be a low salt option
TRUE or FALSE


ANSWERS:
  1. TRUE. Cola based drinks contain caffeine and phosphoric acid which have been shown to adversely affect the bone and hence bone mineral density.
  2. FALSE. An average 30g slice of bread contains approximately 300kJ/70cal whereas a 160ml glass of dry red wine contains a whopping 450kJ/107cal.
  3. FALSE. The Heart Foundation recommends that up to six eggs per weeks can still be enjoyed as long as you are consuming a diet which is low in saturated sat.
  4. TRUE. Emerging research suggests that omega-3 docosahexanoic acid (DHA) may play an important role in the prevention of late onset Alzheimer's disease.
  5. FALSE. According to Cancer Council of Australia, there is no evidence that artificial sweeteners cause cancer, or are at all unsafe in the doses consumed.
  6. FALSE. Wholemeal bread contains bran and wheatgerm which make the bread less energy dense and more nutrient rich than refined white bread. Breads with whole grains are healthier for us as they contain a myriad of vitamins, minerals, phytochemicals, and other nutrients in the inner and outer layers of the grain.
  7. FALSE. Even full cream milk contains only 4% fat, whereas skim milk contains less than 1% fat.
  8. FALSE. Most margarines in Australia contain negligible amounts of trans fats.
  9. FALSE. Incorporating a small portion of nuts such as almonds, walnuts or pistachios into a balanced diet can assist with weight maintenance as they are high in protein and fibre, so are more filling than many other snack food choices.
  10. FALSE. A ‘low salt’ food is defined as a food with a sodium concentration of no more than 120 mg per 100 g. The National Health and Medical Research Council (NHMRC) recommends that Australian adults consume less than 2,300 mg of sodium per day (equivalent to about 6,000 mg (6 g) of salt).
FINAL SCORE:

9-10. Excellent! You know the facts about your food and am up to date with the latest nutritional research.
6-8. Good work. You answered most questions correctly and have a good general knowledge on nutrition.
1-5. Good try! You might want to brush up on some facts on the latest findings that can help you improve your health and wellbeing.

It's important to know the facts about what you are eating. Take some time and do some research - because you ARE what you eat!

Fitness Programs 101 series: Yoga

Imagine meditating while repeatedly chanting aum...aum...aum...aum...For some this is enough to make them fall into a deep slumber (unintentionally, that is), for others this is just one example of a disciplined and effective way of achieving total relaxation and control over the mind and body.


A BIT OF BACKGROUND
Yoga has been around for a very long time, originating in India more than 5000 years ago. Evidence of these origins were found by archeologists in the early 1900s. While excavating at the Mohenjo Daro in the Indus Valley, Sir Mortimer Wheeler, a renowned British archeologist discovered carvings and sculptures depicting poses of humans and animals resembling those practiced by yogis. The artefacts have been dated to 3000 BC.

Sir Mortimer Wheeler's discovery of horn-capped figures sitting in positions which are advanced Yogic postures.
The most famous of these seals is that of an ithyphallic deity now recognised as Shiva.

The word 'Yoga' means “to join or yoke together”, and it aims to bring the mind and body together into one harmonious experience. In yoga, the body is viewed as a temple - a sacred sanctuary that helps us function and evolve in the world.

"The whole system of Yoga is built on three main structures: exercise, breathing, and meditation. The exercises of Yoga are designed to put pressure on the glandular systems of the body, thereby increasing its efficiency and total health."

YOGA FOR FITNESS
There are many different types of yoga practiced around the world. I will discuss in further detail some of the more well known practices.


TYPES OF YOGA
ASHTANGA/VINYASA ASHTANGA
Ashtanga yoga is a dynamic form of yoga consisting of powerful, athletic movements. The movements are sequential and must be performed in this order. Ashtanga literally means 8-limbed which represents the 8 spiritual practices:
  1. Yama (moral codes)
  2. Niyama (self-purification and study)
  3. Asana (posture)
  4. Pranayama (breath control)
  5. Pratyahara (sense control)
  6. Dharana (concentration)
  7. Dhyana (meditation)
  8. Samadhi (absorption into the Universal)
"This method of yoga involves synchronising the breath with a progressive series of postures — a process producing intense internal heat and a profuse, purifying sweat that detoxifies muscles and organs. The result is improved circulation, a light and strong body, and a calm mind."


BIKRAM
Bikram yoga is a sequence of 26 postural poses performed in a heated room. Developed by Bikram Choudhury, an Indian yoga guru, in the 1970s, as a way to "systematically work every part of the body, to give all the internal organs, all the veins, all the ligaments, and all the muscles everything they need to maintain optimum health and maximum function" while at the same time flushing out impurities due to increased perspiration in a 37°C/105°F room.

So why the need for heat? Heat warms up the muscles faster allowing them to work deeper and develop greater flexibility.

HATHA
Hatha yoga is what most people refer to a simply 'yoga'. It is gentle and slow-paced, focusing heavily on the breath and stretching the muscles in static positions with meditation playing a vital part.

'Hatha' means Ha (Sun) + Tha (Moon) and is a union of opposing forces providing "a path toward creating balance and uniting opposites." This form of yoga is all about creating balance between the physical and the psychological and to "further promote the energy flow of the body & relaxation to settle the nervous system & calm the mind".

This is perfect for beginners - giving them an introduction into the world of yoga.


In this day and age where life is so chaotic and fast, practising yoga can help you to relax and slow things down (even if only for a hour). So give it a go and invite some calm into your life.
