BBC Bitesize Science Info Is Wrong

The BBC Bitsize website, designed specifically for helping children learn and revise, provides incorrect and misleading information.

Quote:
A balanced diet contains the different nutrients in the correct amounts to keep us healthy. Certain foods are not necessarily 'bad' for us, but eating too much of them could be. We will look at what food types are needed, how they are digested.
The page on nutrition lists:

Nutrients
There are seven different nutrients:
- carbohydrates                     - minerals
- proteins                                - fibre
- fats                                        - water
- vitamins


According to the Oxford English Dictionary website:

Nutrient: A substance that provides nourishment essential for growth and the maintenance of life.

Carbohydrates are not essential for growth or maintenance. Many people consume carbs but they are a non-essential food. The dietary requirement for carbs is zero!

Fibre is not essential for growth or maintenance. People consume fibre but again, they are non-essential. Fibre may prevent constipation, if refined and processed foods are consumed. Babies get by the first year of their life with no fibre. The dietary requirement for fibre is zero!

That people choose to eat these foods, does not make them essential. Its a matter of personal choice.

Dr Georgia Ede M.D. has a page on fibre, go read it. She closes with this:
Fiber is not essential for human life or health. 
Adding fiber to your diet cannot cure any health problem, because it doesn’t get to the root of the problem. 
If you eat risky refined and high glycemic index carbohydrates regularly, soluble fiber may soften your blood sugar (and insulin) spikes and may reduce your cholesterol a little by interfering with their digestion. 
If you find soluble fiber supplements useful, take care to drink plenty of water with them. 
If fiber bothers your digestive system, or you don’t like eating it, you can safely avoid it, since it is not essential to your health.
The BBC could add alcohol to the list. It's also non-essential, though it does provide energy along with a certain 'pleasure element'. Alcohol like carbohydrates is used and enjoyed by millions of people, but does not make it a nutrient. An essential component of diet for growth or maintenance.

Proteins, fats, minerals, vitamins, and water are all essential. Life cannot be sustained without them. Carbs and fibre are dietary choices.

Carbs may be useful in some instances, such as intense sports. In the absence of carbs, the body can utilize fatty acids for the production of ATP.

The small amount of glucose (blood sugar) required by some organs (brain, blood cells, kidneys) is produced as a by-product of fat metabolism. Any additional glucose requirements, can be produced by the conversion of proteins via gluconeogenesis.

You find this constant feeding of misinformation, via mainstream media. People make unquestioned assumptions and unquestioningly accept much of what they read or hear.
