My Day on a Plate: Helen George, actress 6.15am We film Call the Midwife in an old seminary where there's no heating. Getting up on cold winter mornings is hell! After a cup of tea I head to the make-up bus with a bowl of porridge with honey smeared all over it. 7.30am Start on the first scenes. 9.30am I can feel all my blood-sugar draining out. I bring in trays of fruit (pineapple chunks, strawberries and mango) to eat on set. The trick is to avoid the biscuit tray - there are Jammie Dodgers and custard creams everywhere. 11am Herbal tea or hot water with lemon. 12.30pm The caterers lay out a big spread. I avoid meat when I'm filming because it makes me lethargic later. I pick vegetable tagine with chickpeas, tomato and spinach, with sweet-potato wedges. 4pm After the 10th take of a particularly emotional scene, I'm losing concentration and need a proper tea, with some almonds. 7.30pm Head home to my husband's kedgeree and a glass of red wine. 'Call the Midwife' is on Sundays at 8pm on BBC One Rather than avoiding red meat Helen would do well to try to eat more. Tiredness and difficulty in concentrating are two symptoms of poor iron status. Eating more red meat should help her. She could include more eggs in her diet and also mix some fortified breakfast cereal into her porridge; both are good, easy-to-digest iron sources.
