Don't follow you re genes,longer,healthier life....can you elaborate?
I would suspect that your genetic make up will offer you a greater chance of living a longer, healthier life than those that do not possess them.
Initially the thread was about poor versus good nutrition, thats fair, but some on here seem to mix up nutrition with calories and the obvious visual effects of being obese.
Everything we do will ultimately effect are longevity, but the starting point would be what we were born with and that is genetics.
I am pretty sure that along with smoking on your Life Assurance form they ask about you family history and actuaries are paid a high wage to get this right.
My point remains, offer the information, but I would not want some current fad to directly impact on how I feed my family.
That will be a considered choice I make depending on what might be appropriate for my children at any given time, depending on their activity and lifestyle.
These discussions are generally prejudiced and tend to be delivered by the middle classes to the perceived 'lower classes'.
