Q: I have changed from using artificial sweeteners to sugar in my teas and coffees (eight cups per day), because I’ve been told artificial sweeteners can kill you. Is this true?

A: Artificial sweeteners are completely non-natural, so we should only use them in moderation. The World Health Organization has done safety trials, and determined that one can use up to 10 portions of sweeteners per day, without any health concerns. This would therefore be much better for one’s weight, than adding the extra eight teaspoons of sugar in your daily diet.
