05 The bread stigma - its not the bread that's making you fat ...then what is?


Bread. That's one of the first things we hear people who go on diet say they are giving up.
It seems to be ingrained in our brains that bread = carbs = BAD = gain weight = FAT.
Yes, even I have believed this. When I was 15, I was training for the Junior World Championships in Acrobatics - I didn't eat bread for a year! I substituted eating sandwiches for lunch with yoghurt and protein shakes.

What I find amazing is some people's refusal to eat bread - yet if they saw it scientifically, they would think twice about their food options! Granted, I do not eat white bread - a) it is not healthy because it is made of refined carbohydrates and offers little fibre and b) I find it gives me bad stomach cramps and I feel bloated. What I am talking about though, is brown bread. The specific brand of bread I eat is "low GI brown seeded bread" by Albany. South Africans will know this is the Albany bread with the yellow trim.

In this very short review I want to compare it to something people seem to consume by the gallon without batting an eyelid of the consequences and - even worse - actually believe it is healthy for them. Just what am I referring to - fruit juice.




Compare 1 slice brown bread to 1 glass orange juice
By plugging in the nutritional values on the label of brown bread and orange juice we get the following images:

Is it surprising that a slice of bread has fewer calories than orange juice? What is almost amusing is the fact that people avoid bread because it contains carbs - yet it has only 58% of the carbs of a single glass of orange juice! But you will most surely find many dieters opting for a glass of orange juice over bread under the pretense that it is healthy and full of vitamins and minerals. 1 slice of brown bread contains almost 3 times the amount of protein compared to orange juice which is great when you need to ensure you get adequate protein in your diet to maintain muscle and lose fat. Brown bread has almost 6 times the amount of fibre compared to a glass of orange juice.

Fibre has long been associated to aid in weight loss. Fibre is a bulky food that is more difficult to digest than carbohydrates, promoting the feeling of "being full and satisfied" and prolonging the retention of gastric contents. Gastric retention slows down the rate at which nutrients are absorbed, meaning if the nutrients are absorbed slower, you will not feel hungry again as quickly. Consumption of fibre promotes the production of saliva as well as gastric acids and enhances the desire for water, which further serves to enhance satiety and feelings of fullness. Research has shown that patients who add 14g of fibre to their diet will reduce their calorie consumption by 10%.

The effects of sugar can never be downplayed. 1 glass of orange juice contains 21g of sugar, whereas brown bread has 1/10 of that at only 2.2g of sugar. To put this into perspective for you:
4g sugar = 1 teaspoon

1 glass orange juice = 5 teaspoons of sugar
1 slice brown bread = 0.5 teaspoons of sugar

When you're on a diet, you certainly aren't going to eat 5 teaspoons of sugar in one go so why drink a glass of fruit juice as opposed to eating bread? Really doesn't make sense huh?
Also remember my previous article (http://nutritionalbiochem.blogspot.com/2011/08/03-saving-calories-why-this-doesnt-work.html) - the more sugar dumped into your system, the more insulin is secreted to compensate. At high concentrations, insulin activates the enzyme citrate lyase that turns off energy metabolism, and switches on fat generating pathways.

Remember also, your sugar allowance is only 10% of your total calorie consumption. Remembering from my 2nd article (http://nutritionalbiochem.blogspot.com/2011/07/02-its-all-about-label.html), 1g carbohydrate = 4 calories, then 21g sugar = 84 calories.
If you have a 2000 calorie limit, 84 calories of 2000 is 4.2% of 10% limit - so you've almost had half your sugar limit for the ENTIRE day. Doesn't leave you with much room to eat any other carbohydrates, or, more likely, the chances of you exceeding your sugar allowance for the day are almost guaranteed.

Finally, 1 measly glass of fruit juice isn't going to take you far - it won't be long at all, perhaps even minutes before you start feeling hungry again. Eating a slice of bread is far more substantial and far more nutritious - and actually, far better for your diet.
I could go on and on about the negative effects of fruit juice - don't even get me started on fructose (my entire masters thesis!)

What I'm trying to make you aware of, is that the culprit for sabotaging your diet could be a sneaky thing! Many many MANY people will think they are having a healthy boost start to their morning by having a deliciously cold fresh glass of orange juice - oh how innocent-sounding! Poor bread gets all the blame. Bad bread bad! Orange juice is just smiling and laughing...and making you fat.

If I can give any advise, seriously limit your intake of fruit juices. Many people do not realise to make 1 glass of fruit juice requires at least 3-4 pieces of fruit, when realistically, you would never sit and eat 4 oranges in 1 go. If you're on a diet, drink water.
If you really want fruit juice, either, dilute it with water (half glass fruit juice+half glass water) or do what I do: Just drink half a glass or less - on the odd occasion. You will notice many fruit juice labels state per 100ml. That's about 1/3 of a glass.
Its not always about cutting out, its all about moderation.


I decided to add this after publishing: Just so you don't think its orange juice that is worse than bread but all fruit juice, I am adding in the nutritional labels from other juices below:

  1. So true! I found in the US, that the labels on fruit juices are so deceptive...I mean they say "100% all natural" or "Not made from concentrate" and then the fine print on the back says "..with additives". I mean come on! Then also, on the nutritional info they put Vit A, Vit C, Iron, etc and the amount in the juice are noted as "0%"! Why put it on the label if its not even in the juice-I guess they hope the consumer reads it so fast that they neglect the fact that there is 0%! So check the fine print and read the fine print,don't skim-read.

  2. Seems to me the "bread stigma" remains valid. Most of the bread options out there are either white bread or standard brown bread, both of which are high GI. Not many people like the low GI seeded bread varieties. It is still much healthier to replace all bread in your diet with vegetables as a source of carbs, as the nutrient load is significantly higher.

  3. I don't drink fruit juice anymore either, unless it comes with the rest of the fruit so that I can get the benefits of the fibre in the fruits as well...
