I had a friend years ago who was into his food combining. If I understood correctly carbs and protein are digested best in alkaline and acidic environments (think it was that way round) and that if you eat both at the same time your stomach has to do far more work and it's more likely stuff isn't going to be digested properly and be stored as fat. So the idea is you only eat one food type at a time, it gets digested more efficiently, and then you have the next food type, giving you more energy and making you lose weight at the same time I think the acid/alkali thing is FACT
The acid alkali thing makes no sense to me. Are you suggesting that your stomach senses what type of food you've eaten and changes its PH accordingly?
they had lots of info and stands promoting diet soft drinks over fruit juice which contains 'lots of sugar' and is therefore bad. Apprantently totally unaware of the growing research that has been circulating for several years linking sweeteners to weight gain not to mention the links with cancer the people manning the stands were insistant that pure fruit juice was unhealthy due to it's high sugar content. Apparently contradicting the '5 a day' advice.
But returning to the overall question of whether it is still worth eating 5-a-day, the major reason not to stop yet is spelled out by Willett: where fruits and vegetables may be failing against cancer, they are certainly succeeding against other diseases, especially coronary heart disease, obesity and constipation. In exactly the same EPIC population where fruit failed against cancer, those consuming at least 5-a-day lowered their risk of coronary heart disease or stroke by 30 per cent compared with those on less than 1.5 servings a day.
