The brain relies solely on carbohydrates as its primary source of energy.
Humans obtain energy from three nutrients: carbohydrates, fat, and protein.
Carbohydrates are essential for maintaining blood sugar levels, which must be kept at a certain level to prevent a decrease in energy supply to brain cells.
If blood sugar levels fall too low, it can lead to brain failure and loss of consciousness.
While converting carbohydrates to storage (neutral fat) is less efficient, the remaining carbohydrates can easily convert to fat.
It’s essential to differentiate between good and bad carbohydrates.
Natural carbohydrates that slowly raise blood sugar are preferable to refined carbohydrates that are quickly digested and cause rapid blood sugar spikes. Eating carbohydrates with protein or fat slows the digestion process, preventing over-stimulation of insulin secretion.
To consume carbohydrates healthily, it’s recommended to apply less heat when cooking and consume raw foods, as this can lower the glycemic index.
For example, raw sweet potatoes have a lower glycemic index than boiled sweet potatoes.
Eating uncut whole foods, such as unpolished brown rice and fruits with their peel intact, can also lower the glycemic index.
Finally, consuming foods high in dietary fibre, like vegetables and seaweed, slows digestion rates, allowing blood sugar to increase slowly.
