Nutritional guides have been prone to wild fluctuations and rearrangements over the past several decades, vary sharply by country, and have been influenced by everything from scientific studies and wartime rationing to the agriculture industry and food prices. Thank goodness for 1968’s A Cruel Kindness, then, which makes such a guide as basic as can be. According to writer/director Winifred Holmes’s film, the three food groups are carbohydrates (“energy”), fat (“warmth), and protein (“for growth”). And sometimes, small quantities of vitamins. The filmmakers make no effort to explain what benefits this last group provides, likely because no documentary team wants to bore viewers with a discussion about watercress. We get it — it’s really good for you! Enough already, watercress. You’re almost as insufferable as kale.
