A year ago a journalist placed a (metaphorical) bomb under the most influential nutritional body in the world – the DGA. It tells Americans what to eat to stay healthy. Low fat? Low carbs? The GDA decides. Last week the bomb went off. The DGA wasn’t giving good advice. It had favoured low fat for decades but the evidence of benefit was tiny and ignored the most current science when it dismissed low carbs. Meet the rebels and the victims.
