Always prefer slightly or non-processed products: whole wheat and bread, Basmati or whole rice, cooked soy, (whole) breakfast cereals, whole cane sugar, dark chocolate... Such products have a weaker glycemic index than the ones previously mentioned. Here are, as an example, 10 commonly consumed nutrients:
Refined |
GI |
Slightly or non refined |
GI |
|---|---|---|---|
White sugar |
100 |
Whole cane sugar |
70 |
French fries |
95 |
Boiled potato |
65 |
White bread |
85 |
Whole bread |

Corn flakes |

Spécial K |

Overcooked regular pasta |
85 |
'Al dente' pasta |
50 |
Fast-cooking white rice |
85 |
Whole brown rice |

Coca cola |

Fresh-squeezed orange juice | 45 |

Glycemic index? The first things that come to mind when one refers to the glycemic index are anti-diabetes or weight-loss diets. But, according to recent research in the United States*, a high glycemic index indirectly favours the secretion of androgen hormones: that is why the hair is also affected. Processed products cause a chain of damaging hormonal reactions, for skin in general (puberty acne) and especially for the scalp.
In detail: Their higher level of sugar goes through the blood too quickly and triggers a sudden increase in the level of insulin, which stimulates the surrenal glands and activates the secretion of surrenal androgen, which, in turn, frees sebum and leads to the formation of sebaceous toxins. Those toxins (greasy cellular waste) place themselves under the scalp, thus preventing the blood to flow as it should towards the roots, and risk restraining their development.

Be careful about cooking time !
The level in sugar is not the only cause for the increase of the glycemic index: cooking time also plays a part. The more an ingredient is cooked, the faster it is digested, and the more its glucose will suddenly enter the blood stream and trigger the chained reaction described above. Therefore, because al dente pasta (IG 50) is digested more slowly than lengthily cooked pasta (IG 85), its glucose will progressively spread throughout the blood, without generating an insulin climax and requiring an excess of androgens.
* Research initiated by the works of Dr. Loren Cordain, who was the first to show the incidence of refined nutrients on skin (2002).
On the other hand, throughout the refinement process, the nutrients that are essential to producing the hair are largely or totally lost: protein, iron, zinc, vitamin B (see the remaining parts of this section). Also, refinement diminishes the nutrients' fibres, which contributes to increasing their blood sugar level. As an example, for a 100 g intake:
Proteins |
Iron |
Zinc |
Vit. B6 |
Fibres |
|
Whole bread |
10,6 g | 2,2 mg | 5 mg | 0,21 mg | 7,5 mg |
|---|---|---|---|---|---|
White bread |
8,2 g | 1 mg | 2 mg | 0,12 mg | 1,7 mg |
Whole sugar |
0,8 g | 4 mg | 0,3 mg | 0,4 mg | |
White sugar |
0 g | 0,1 mg | 0 mg | 0 mg |
Level for 100 g intake |
OUR OPINION. The excessive solicitation of androgen and the alteration of nutrients, via our unnatural contemporary eating habits, is not sufficient to cause androgenetic alopecia. However, it certainly has an aggravating effect and can in part explain the increased level of men hair loss over the past forty years.
