Help may be here if you want to keep the wrinkles and grey hair away and slow down the aging process. New research says that eating green vegetables can delay the signs of aging. Researchers say that broccoli and avocado in particular have a compound that slows down the rate we age at. It is also in green fruit and is called NMN. It helps slow down the signs of getting old. Scientists say NMN can also refresh the metabolism. It helps restore levels of energy production in our body that weaken as we age. It also helps reduce weight gain and the worsening of our vision.

The research is from the USA's Washington University School of Medicine. Professor Shinichiro Imai said: "We have shown a way to slow the physiological decline that we see in aging mice. This means older mice have metabolism and energy levels resembling that of younger mice." Professor Imai said NMN reduced the usual signs of aging. These include weaker muscles, poor liver function, lower bone density and poorer eyesight. The reason our metabolism changes over time and leads to reduced energy levels has been a puzzle for decades. This latest research casts new light on this.
