&gt; For Leila, the results were very different. Whereas pasta was &quot;bad&quot; for me, it was fine for her. Yoghurt was good for me, but bad for her, and our responses to bread and butter were also complete opposites.<p>(Note: &quot;bad&quot; and &quot;good&quot; above refers to &quot;high-GI&quot; and &quot;low-GI&quot;, respectively.)<p>Another interesting anecdotal observation from my acquaintances: our relationships with food differ significantly. While some people simply <i>like</i> to eat (like myself - I find great pleasure in food and seemingly can&#x27;t ever get enough), others simply don&#x27;t find such enjoyment in eating - food tastes good for them, but not particularly amazing, and they don&#x27;t seem to perceive the same amount of Freudian pleasure from the feeling of fullness. Interestingly, this seems to correlate highly (and again, anecdotally) with our life-long struggles with weight - the first group has to be conscious not to eat too much (and put on too much weight), while the second group consists of mainly skinny individuals, some of whom struggle putting on weight.<p>So the &quot;goodness&quot; and &quot;badness&quot; of food might have completely different base levels across population!
