1. Is there mercury in the fish I eat? Doesn't matter if you drink tea or black coffee soon after eating fish.

Stick to prawns, tuna, salmon and you should be fine and ... drink tea or coffee (according to Canadian researchers).

2. Are you vegan or vegetarian? Then you'll need a nutrient top up. Vitamin B12 will be in short supply in your diet so eat spinach, kale and soy milk. Iron is the big nutrient you'll be missing so beans, tofu, sundried tomatoes, potatoes and peanuts. You'll miss calcium so eat figs, spinach, broccoli, tofu and soy yoghurt. You may also be missing omega-3s so fill up on flaxseed oil, walnuts, soybeans and flaxmeal.

Add some chopped up kale to your fruit smoothie or try some well-blended cannellini beans. Yum, and good for you!
