According to an article on The Daily Mail, a study found that including both plant and animal foods may increase the chances of living to 100 for people who are very old or underweight. However, this effect disappears in individuals with a healthy body weight. The study's most significant finding was that daily vegetable consumption had the strongest association with longevity, with those who ate vegetables daily being 84% more likely to reach 100.

In conclusion, the real secret to living longer seems to be a plant-based diet, not meat. Daily vegetable consumption was found to be the key factor in increasing longevity. While the Daily Mail may promote sensational headlines about the benefits of meat consumption for reaching 100 years old, the study indicates that a diet rich in plants, particularly vegetables, is essential for a longer and healthier life.
