The Queen lived for a long time because she cared about her diet. She never ate seafood in foreign countries because she didn’t trust the preparation. Close sources said that she didn’t eat carbohydrates in the evening either. This was because she didn’t want to gain weight.
But she loved chocolate in all its forms and regularly indulged. She also enjoyed a tipple in the evening and always had a nightcap before bed. Balance was the key to her life but she knew what she liked. This didn’t include garlic because she never allowed it on menus (via Good Housekeeping).
