How healthy or unhealthy is toast?

Sunday morning breakfast time. If the baker is too far, toasted bread is quickly at hand. Is toasted bread particularly unhealthy? No, but certainly not very nutritious and therefore not wholesome. Sometimes it can also be toxic and even cancer-causing. We have put together the most important facts.

Not particularly nutritious

Butter toast contains hardly any minerals and fiber. It is therefore not particularly nutritious. Many therefore think that whole grain toast is the better alternative. Whole grain toast contains minimally more nutrients than white toast, but of course much less than whole grain bread. Whole grain toast is also a fake product because it suggests that it is whole grain. Instead, it is toasted bread made from conventional dough that is only enriched with grains.

Whole grain toast has more fat

Did you know Whole grain toast contains significantly more fat than butter toast. White contains on average 3.8 percent fat, whole grain 4.5 percent and grain toast 9 percent. “The higher value results from the addition of seeds from linseed and sunflower seeds. However, these unsaturated fats are healthy, ”says Carolin Klose, fitness and nutrition consultant from Hanover.

If toast is declared as a “whole grain toast”, the processed flour must contain at least 90 percent actual whole grain. If you look at the list of ingredients, there are values ​​between 50 and 60 percent depending on the provider. This is because toast contains other ingredients besides flour. The percentage of whole grain on the package refers exclusively to the whole product and not to the flour portion.

Toasting produces acrylamide

Less attention is paid to the fact that toasting creates dangerous acrylamide the darker the toast is roasted. According to the unanimous opinion of most nutritionists, acrylamide is considered to be carcinogenic and can also damage the genome.

The food toxicologist Prof. Bernd Schäfer from the Federal Institute for Risk Assessment said: "The more browned they are, the higher their acrylamide content." According to Schäfer, there are scientific studies with animals that indicate this. If there are black spots on the toast from roasting, it should be thrown away. Simply cutting off the black areas is controversial. At temperatures below 180 degrees Celsius, significantly lower amounts of acrylamide are produced than at higher temperatures.

Proper storage keeps you fresher

How do you properly store toasted bread? There are various opinions on this. As a rule, toasted bread can still be enjoyed after the expiration date. As soon as greenish spots appear, toast should be disposed of. Place the toast in a bread box for storage. Some also keep it in the fridge. But here it loses a lot of taste. If you want to keep toast bread for a longer period of time, you can store it in the freezer for 3 months. The advantage: The slices can be removed individually so that they can be toasted directly.

Warning poisonous places

If mold has formed, not only the individual pane should be disposed of, but the complete package. Mold has spread even when it is not visible everywhere. The mushroom runs invisibly through the entire bread. Mushroom poisons also defy heat and can cause severe poisoning in large quantities. They damage the immune system and damage the kidneys and liver. In addition, mold is suspected of causing cancer.

Conclusion: Toast is not the healthiest food, but can be enjoyed from time to time. There are some aspects to consider - as described. However, it is better to eat whole grain bread from whole kernels regularly. Slices of toast should be the exception and not the rule. (sb)
