Update - yes I'm still alive

December 4th 2011 01:38
Update
I haven't been posting on here very much because it has been quite hectic lately. Work is terribly busy, I've just finished my course for the year (post grad health psychology) and I've been doing a bit of work for the heart foundation, steering a yatch for the very first time and now its time for Christmas celebrations and the like. So when it calms now I hope to write a bit more, possibly about psychology/health because I'm finding it to be much more interesting. Perhaps I should start a new blog? I don't know. Anyway, I shall be off to the gym, I haven't been in a week and half due to working 11 hour days. I'm almost excited about burning off that energy.

GI, body fat and hangover cures

September 23rd 2011 20:42
Hi everyone, this week I answer a few questions about GI, measuring body fat, hangover cures and energy.

What is GI?
GI stands for glycaemic index, which gives an indication of how quickly the carbohydrates in a food and drink are converted into blood glucose compared to pure glucose. The GI of a food can be between 1 and 100 (glucose having the GI of 100). The higher the GI rating, the quicker the carbohydrate in the food or drink is broken down into glucose and released into the blood. High GI foods raise blood glucose levels higher and quicker than lower GI foods. Blood glucose levels also drop quicker too. Whereas, with low GI foods glucose is released slowly. GI is useful for planning a diet that will keep you fuller for longer (hunger is stimulated when the glucose levels drop) and to help stabilize your blood glucose levels, this is particularly useful if you are an endurance athlete or a diabetic. It is encouraged to eat low GI foods, but they are not necessarily the healthier options. For example, a food rich in saturated or trans fats and high in sodium, can have a very low GI, but I would not recommend eating foods like that on a regular basis. Saturated fat, trans fat and sodium is typically linked to poor heart health. We can eat a little and be healthy, but too much can be unhealthy.


Standard GI Ranking
GI Ranking GI Range
Low Less than 55
Medium 56-69


What is a kilocalorie (Kcal)? What is a kilojoule (Kj)?
Both a calorie and a joule are measurements of energy. A Kcal is equivalent to 4.2Kjs. Women need about 8800Kj or 2000Kcal per day, while men need about 11000Kj or 2500Kcal per day, to help our bodies function correctly. 55-65% of this energy should come from carbohydrates, 15-20% from protein, and 20-30% from fat. Carbohydrate rich foods include, rice, bread, noodles, fruit, veg, and pasta. Protein rich foods include, beans, fish, meat, eggs, soy products; and fat rich foods include avocado, nuts, seeds, and vegetable oils.

Can you tell me about BMI and other similar measurements?
BMI stands for body mass index, which is found by dividing your weight in kilograms by your height in metres squared. BMI is one of the simplest measurements used to estimate body fat. Its correlation with body fat is high, and it is not suitable for certain groups, such as, pregnant women and body builders. The normal range for BMI is 18.5 to 25.0 for NZ Europeans, and 18.5 to 26.0 for Maori and Pacific Islanders.

Skinfold thickness measurements is measurement related to BMI, they are both indirect ways of estimating body fat. This method of estimating body fat is based on the assumption that total body fat and subcutaneous (just under the skin) fat are relatively constant, thus total body fat can be estimated by measuring the amount of subcutaneous fat. Subcutaneous fat can be estimated by measuring skinfolds using a skinfold caliper. This form of body fat estimate becomes less accurate when used on older and obese people.

Waist-to-hip ratio (WHR) is a measurement, which is used to identify those at risk of obesity related disease. WHR is calculated by dividing your waist measurement by your hip measurement. A WHR 1.0 or higher in men and 0.85 or higher in women indicates an increased risk of disease.

Do you have any hangover remedies?
Yes. Headaches from hangovers are caused by alcohol-induced dehydration. To help prevent this from happening, you can either not drink alcohol at all, or you can keep hydrated. Make sure you drink plenty of water before you go to bed and avoid caffeine and more alcohol, as they can both diuretics and they can therefore dehydrate you!

Mostly just for fun

July 30th 2011 08:48
Question one: We have recently lost our flat mate of high nutritional value, can you tell me where I can get a flat mate of equal or higher nutritional value?

I recommend going to DTR, you can hire all sorts of goods there – refrigerators, washing machines, televisions, and even flat mates. Another thing you can do is put an advertisement on Trade Me’s Flat Mate Wanted page. However, there are no guarantees that the flat mate you purchase will be as highly nutritious as the awesome flat mate you once had. Lastly, you can advertise in a newspaper, such as Chaff. Again, there is no guarantee that you will get a high quality flat mate.

Question two: What is more nutritious, Styrofoam or cardboard?
Cardboard is made mostly from cellulose, which is a type of fibre found in plants. Styrofoam on the other hand is made of polystyrene, a type of plastic. From this information, I would have to say that cardboard is more nutritious since the body needs fibre but it does not need plastic. However, I don’t recommend eating cardboard because after all it does taste like cardboard.

Question three: What do you think of the Raw Food Diet?

First all, I should clarify what the Raw Food Diet entails. It is a diet which consists mainly (or entirely) of uncooked, unprocessed, and often organic food. The diet may include a selection of raw fruits, vegetables, nuts, seeds, eggs, fish, meat and unpasteurized dairy products.

From this bit of information, I would have to say that the benefit of this diet is that it is low in processed foods. Processed foods high in additives and some people may be unable to consume them. They’re often high in refined sugar, salt and trans fat, which can be harmful in large amounts. Sugar can cause dental cavities, and a diet high in salt and trans fat can lead to high blood pressure. Another benefit of this diet is that it is rich in fruit and vegetables, which is always a good thing.

However, on the downside, since the Raw Food Diet is free of cooked foods, it is harder to remove harmful bacteria. This is particularly bad for pregnant women. Eating un-pasteurized dairy products and raw egg is not recommended for pregnant women, as they un-pasteurized dairy products may contain microbes, which can be harmful to the fetus.
Additionally, you may miss out on some nutrients such as vitamin B12, which is found in meat and Marmite.

Question four: What do you think of the Airplane Diet?

The Airplane diet was founded by a man named Michael Lotito in 1978, when he discovered that humans (or at least he) could consume airplanes. Michael is an entertainer who is famous for consuming “inedibles” such as metal, glass, rubber, bicycles, and televisions. It has been estimated that from 1959-1997 he has eaten nearly 9 tons of metal. He does not suffer any ill effects due to his diet, even though he often eats things, which are considered poisonous. In my opinion, I don’t recommend that the average person follows the Airplane Diet.

If you would like to ask me anything that’s nutrition related then please send me an email to nutrition.advice@gmail.com.

Another column written for a university newspaper.

In this column I cover topics such as staying healthy on holiday and eating well during pregnancy. Now I am aware that not too many university students are pregnant. However, I’m sure you will find it interesting and you can always pass this information onto anyone who is pregnant

KFC's Double Down

June 3rd 2011 23:34
Ah yes, the KFC Double Down. It’s here in New Zealand for a short visit of five weeks. For those who have not heard of the Double Down, it consists of two Original Recipe chicken fillets, two slices of bacon, two slices of cheese with sauce. It has been dubbed a nutritionist’s nightmare. Being as curious as a cat, I investigated the nutritional value of this burger and compared it with burgers from other burger joints. And this is what I have found...

According to Really Long Link which provides nutritional data on the food items sold in the American KFC restaurants, the Double Down with grilled chicken fillet is weighs 253g, has 480 calories (2000kj), 25g of fat, (9g of that is saturated fat), 1770mg of sodium, and 2g of sugar

Win curries

Krissi’s chickpea tikka masala
Okay this is not a traditional curry of any cuisine, however it very tasty and suitable for herbivores like myself. I quite like this recipe because it quick and easy to prepare, low in saturated fat, and high in protein. The chickpeas supply a source of protein, calcium and fibre, tomatoes are rich in vitamins A and C and rice is a source of carbohydrate. If you want to make this extra healthy, use brown rice. Brown rice is much more nutrient dense than white rice, it has higher levels of fibre, B vitamins and zinc

5 plus a day

April 20th 2011 09:34
This week I have a question from one of my lovely readers. She asks:
“You know what I would like to know.. if you use fruit in baking etc, how much of its goodness is lost? Like if I made apple muffins, and then served them to the boys it does not count as a teeny bit of fruit intake does it??”
Heat and light can destroy nutrients such as vitamin C, which is found in fruit and vegetables. However heat can make some nutrients, such as beta carotene (a form of vitamin A) more available. These are found in yellow, red and orange fruit and vegetables

Healthy, tasty, cheap recipes

February 25th 2011 21:47

Roasted vegetables
This recipe is quite simple and you can use any vegetables that you can roast. I like to use kumara, potato, pumpkin, carrot, tomato, mushroom, and onion. Chop the root vegetables into small cubes. Turn the oven on to bake at 200C. Spray one tray with vegetable oil and sprinkle the chopped vegetables with either Tuscan seasoning or roast seasoning. Put in the oven. Chop up the mushrooms in half or if you have Portobello mushrooms you can use them whole. Chop the tomatoes into thirds and thinly slice the onions into rings. Place these vegetables on a lightly sprayed tray and put in the oven. Take the root vegetables out when they are golden brown and tender. Serve and eat straight away or cool and make them into a roasted veggie salad
