Negative Health Aspects of Consuming White Bread
So what are the negative health aspects of eating white bread?
To begin with, as with white pasta and other products made from refined white flour, white bread contains a large proportion of high GI (glycemic index) carbohydrates. These carbohydrates cause sugars to be released quickly into the bloodstream. This causes a rapid rise in blood sugar levels which triggers a similarly rapid release of the body’s own sugar regulating hormone, insulin. This hormone is secreted in the pancreas and is responsible for regulating blood sugar levels. Insulin is what people suffering with type 1 diabetes have to inject to regulate their blood sugar levels because their body does not produce sufficient naturally. Type II diabetes is a rapidly spreading disease brought on by too frequent imbalances in blood sugar levels causing insulin production to become overworked, which eventually leads to the problem and all the negative health aspects associated with it.
Other negative health aspects come in the form of raised levels of bad LDL cholesterol in your bloodstream. This can lead to problems such as heart disease related to the narrowing of the arteries. When levels of LDL cholesterol become too high artery walls thicken and blockages can occur, leading to thrombosis (blood clots) as well as high blood pressure.
Another negative effect of eating white bread is on the body’s metabolism. This is retarded causing reduced efficiency in digestion and greater fat storage, which is more often than not accumulated around the belly. In fact, this is one of the main reasons why weight loss is so difficult for people who continue to eat white bread. Not only that, but it makes you feel more sluggish and less inclined to want to exercise. The lack of dietary fibre is a big problem for your digestible tract especially the intestines that finish the job and allow waste to leave the body. When there is little or no dietary fibre present in your diet, your colon will suffer and be unable to effectively remove all waste products from the body. This leads to such diseases as Crohn’s, Irritable Bowel Syndrome (IBS) and can lead to cancer of the colon.
But all is not lost! While eating white bread is bad for your health, bad for your weight and bad for your digestive system, there is a nutritious, healthy alternative!
The Alternative to White Bread
You don’t have to give up bread from your diet, just white bread. The viable alternative is of course brown bread, otherwise known as wholemeal or wholegrain bread. This is produced from wholemeal flour which is not refined in the same way as white flour. Wholemeal flour retains the husk of the wheat, or bran which is where all the nutrients and dietary fibre exist. There is no bleaching either and gluten levels are generally lower than in white bread, although you should always check the label for this information first.
Wholemeal flour contains much lower levels of high GI carbohydrates than white flour and also higher levels of low GI carbohydrates, which work in the opposite way to high GI carbohydrates, as the low GI carbohydrates contained in wholemeal bread produce the slow release of sugars into the bloodstream. The upshot of this is that insulin is only slowly released into the bloodstream and in far lower amounts. The metabolism is stimulated rather than inhibited, meaning that your digestive system gets a boost in efficiency and less fat gets stored. This is good news for slimmers and anyone concerned about their weight.
Wholemeal flour products like brown bread contain high levels of dietary fibre. This is essential for the functioning of the colon and the complete digestion of food and waste elimination. They also contain lower levels of bad LDL cholesterol with higher levels of good HDL cholesterol. This means healthy arteries and a better normalised blood pressure, bringing with it better health and less concern over the negative effects of white bread.
To finish things off, brown or wholemeal bread tastes good and doesn’t have that cloying, pasty texture that massed produced white bread tends to suffer from. Make the switch to wholemeal bread and you’ll quickly grow accustomed to its taste and texture. Soon you’ll find yourself preferring its superior taste along with all the health benefits and goodness that come with it as part of a healthy, tasty diet.
