Если лично Вам нравиться свинина по 1 евро на кг, то ешьте. Я на питании даже будучи бедной студенткой не экономила. Насколько овощи и фрукты различаются по вкусу и качеству вопрос спорный, тут я согласна. Но мясо различается значительно и по вкусу и свойствам.

Вот вам навскидку про протеины:

The results indicated that heat-treatment temperature and time have significant effects on the whey protein denaturation and the combination of whey protein and casein. With the increase of temperature and time of heat treatment, both the denaturation degree of whey protein and the combination degree of whey protein and casein increased. The denaturation and the combination degree was found to have the quadratic regression relationship with the heat-treated temperature and time. The equations proposed in this study can be used to figure the detailed relationship between the denaturation degree of milk protein and heat treatment conditions. It is essential for dairy industry to choose suitable heat treatment conditions to improve the stability of the milk protein and reduce nutrition loss.
