There is growing evidence that sirtuin activators may have a wide range of health benefits as well as building muscle and suppressing appetite. These include improving memory, helping the body better control blood sugar levels and cleaning up the damage from free radical molecules that can accumulate in cells and lead to cancer and other diseases.
‘Substantial observational evidence exists for the beneficial effects of the intake of food and drink rich in sirtuin activators in decreasing risks of chronic disease,’ said Professor Frank Hu, an expert in nutrition and epidemiology at Harvard University in a recent article in the journal Advances In Nutrition. A sirtfood diet is particularly suitable as an anti-aging regime.
Although sirtuin activators are found all through the plant kingdom, only certain fruits and vegetables have large enough amounts to count as sirtfoods. Examples include green tea, cocoa powder, the Indian spice turmeric, kale, onions and parsley.
Many of the fruit and vegetables on display in supermarkets, such as tomatoes, avocados, bananas, lettuce, kiwis, carrots and cucumber, are actually rather low in sirtuin activators. This doesn’t mean that they aren’t worth eating, though, as they provide lots of other benefits.
The beauty of eating a diet packed with sirtfoods is that it’s far more flexible than other diets. You could simply eat healthily adding some sirtfoods on top. Or you could have them in a concentrated way. Adding sirtfoods to say, the 5:2 diet could allow more calories on the low-calorie days.
A remarkable finding of one sirtfood diet trial is that participants lost substantial weight without losing muscle. In fact, it was common for participants to actually gain muscle, leading to a more defined and toned look. That’s the beauty of sirtfoods; they activate fat burning but also promote muscle growth, maintenance and repair. This is in complete contrast to other diets where weight loss typically comes from both fat and muscle, with the loss of muscle slowing down metabolism and making weight regain more likely.
