Nevertheless, the mutator mice
showed no
signs of premature
aging, such as osteoporosis, balding, or
reduced fertility, the team reported online 4 March in Nature Genetics.
Now, scientists have
shown that supplementing healthy mice with NMN — found in foods such as broccoli, avocado, cabbage, and cucumber — can compensate for this loss
of energy production,
reducing typical
signs of aging such as gradual weight gain, loss
of insulin sensitivity and declines in physical activity.
