Sugar - What's the go?

Sugar. We all like it, and we are all confused about it. There's so much misinformation online about sugar, that it's causing many people to become frightened of food and severely restrict what they eat. Tara felt the need to clear a few things up, tackle the piffle and nonsense head-on, and answer the following questions:

• What are the current recommendations around how much sugar we should have? 
• What's the 'healthiest' sugar? 
• Will fruit make us 'fat?' 
• Do they add sugar to low-fat milk? 
• Is sugar addictive?
