“I’ve been taking an iron supplement for three weeks and still feel tired.” This was the comment from a woman attending a series of nutrition seminars I was running. She had been discharged from hospital three weeks earlier and prescribed an iron supplement. “When do you take it?” I asked her. “With breakfast,” she replied. Breakfast consisted of muesli with low fat milk or wholegrain toast and a cup of tea. A healthy breakfast – yes. But a suitable meal to take an iron supplement – no.

Supermarket ad trials: your shopping trolley knows what you want — In a move that brings new meaning to the expression “taking the thinking out of shopping”, advertising will be delivered directly to supermarket trolleys based on a shopper’s in-store behaviour and purchasing history.

It could make shopping more entertaining but I prefer to choose my groceries without my trolley telling me what to buy!

The Auckland Food Show is on this weekend. I went with a friend today. Here’s my take on it.

[tweetmeme]Most unusual food: Halfords Earth Gems
.

Earth Gems are multi-coloured, bite-sized vegetables that ‘are the jewel of the South American Incas’. They grow like a potato but are from the beetroot family and have an earthy taste. You sure know you are eating something straight from the ground. I think they are an acquired taste! With all those colours they are bound to have plenty of antioxidants.

Most native Kiwi drink: Kawakawa Fire Tea

A caffeine free tea made from kawakawa, lemongrass and ginger by T leaf T. It’s packaged beautifully with a simple Maori design. A lovely present and it tastes great.

Food I bought today and have already used: Australian semi-dried tomatoes and Monin vanilla syrup

I used the tomatoes on pizza but should have kept them for a salad. They were too delicious to waste on pizza. I mixed the vanilla syrup with low fat milk for a delicious instant vanilla milkshake. I also bought Monin’s Chai Green Tea Extract to make Chai Latte – a sweet, milky alternative to coffee.

What I’ll use tomorrow: New Zealand Breakfast Tea

A black tea blended with manuka. It smells like honey but tastes like tea. It should taste great with grainy toast and honey for breakfast.

Best buy: Dutch Maasdam cheese

It was half-price – about $20 per kilo. I bought a huge chunk!

Most interesting food: Cherry juice that helps you sleep

This tart cherry juice is made from Montmorency cherries from Canada. According to the promotional leaflet these cherries have significant levels of melatonin which promotes sleep. It’s 100% juice with no added sugar or preservatives which is good. It comes in a concentrate which must be kept in the fridge or freezer to maintain its nutritional value.

Food that brought back the best childhood memories: Fresh walnuts

There was always a tray of walnuts drying in the sun at my grandparents. We would spend ages helping my Nana to crack them open. My grand-dad liked them dipped in icing. Walnuts contain alpha-linolenic acid (a type of omega-3 fat) so make a healthy snack, preferably without the icing!

Biggest trend this year: Anything with omega-3 in it.

There was flax seed oil, biscuits, pills for kids that taste like jelly lollies, and even smoothies made with flax seed oil. Parents seemed most enthusiastic about these foods. I just hope they don’t mega-dose their kids. Omega-3 fats are good and most of us could do with a bit more but as with all nutrition too much of one nutrient is likely to upset the balance of others. Also flaxseed, like walnuts, contains alpha-linolenic acid which converts to EPA (the omega-3 fat in oily fish) in the body. The conversion rate is about 8% so you need to eat quite a bit of flaxseed to get the same effect as a from a meal of salmon.

Most organised person

The woman who had a suitcase on wheels filled with all her purchases. She had already made one trip back to the car to unload and was on her second round.
