The article mentions a connection to obesity. "To what degree would a shift in the food system contribute to that? We can't really say.” I really wonder if this already a part of the worldwide obesity crisis. More carbs/nutrition in the food leads to more calories/nutrition. So, on average, you would have to consume more calories to get all required macro and micro nutritions. The effect doesn't have to be big. Just a few more percent in calories consumed can lead to a large weight gain, compounded over many years. I'm likely missing some important pieces on nutrition science but it's interesting to play with the numbers. The article says that the amount of 'important minerals' might drop by 8% in the future. Let's say it has already dropped by 5%. In order to get the same amount of minerals today, you have to eat about 5% more of the same food leading to about 5% more consumed calories. Let's say you would keep your current weight at 2500 kcal/day, but now you consume an extra 150 kcal/day. Assuming a weight gain of 1 kg/7700 kcal, this would lead to a weight gain of 150 kcal/day x 1 kg/7700 kcal x 365 days/year = 7 kg/year. Hence, a 1.65 m tall person starting with a weight of 60 kg (BMI = 22, normal weight) would be considered obese within a mere 3 years (81 kg, BMI = 30). Of course, the increase in CO2 and subsequent drop in nutritions with a magnitude of 5% takes place over a longer time span than 3 years. But I still find it interesting, that apparently this effect could explain an enormous amount of the obesity puzzle. If, hypothetically, humans wouldn't have changed the composition of their diet or calorie expenditure at all, but their bodies are tuned to maintain a fixed amount of nutritions, the small drop in nutrition content alone could apparently explain a worldwide increase in obesity.
