"Our diet and lifestyles have changed dramatically in what would be a blink of an eye in evolutionary terms. Our bodies simply haven't had the time to adapt." - It is true that in recent times, we have moved away from eating traditional foods, and have moved towards eating processed and refined foods. We have also become more sedentary, and lifestyles less active. There are many well known health implications to this. This is most true for indigenous populations, who have experienced these changes most rapidly. Indigenous Australians, for example, who were living as hunter gatherers before the arrival of Europeans to Australia. In this article about nutrition and growth among Australian indigenous peoples: http://www.healthinfonet.ecu.edu.au/health-risks/nutrition/plain-language/our-review the health implications of this are acknowledged. However, it also states that babies of indigenous Australians thrive and grow normally, whilst still breastfed, and it is only once weaned to solids that they encounter health and growth issues. Science is not our enemy, however it is also not without it's limitations and corruptions and should not be regarded as an unquestionable authority.
