Here are some simple tips you can apply at any age to improve your gut health pretty easily:
1 Avoid any foods you know you have a reaction to. Obvious, I know.
2 Chew thoroughly. I’m talking 30 to 50 times per mouthful!
3 Avoid drinking liquids shortly before or after eating
4 Avoid treating every instance of indigestion with over the counter medication. Instead seek to understand why the problems occurred in the first instance
5 Be wary of mixing fruits with other foods. Many people can handle this, but for others mixing fruit with other foods causes an almost instant reaction. This is because the foodstuffs are digested at different rate, putting a strain on your stomach.
6 Speak to a dietician or your GP about the use of probiotics or digestive enzymes if problems persist
Keeping the mind healthy
Slowly, we're coming around to the fact that mental wellbeing is just as important as physical fitness in terms of our overall health. In fact, the two are entwined: your mental state effects everything from your blood pressure to hormones and resting heart rate.
Remember that no training plan or diet is going to be completely effective if you are in a bad place mentally and emotionally.
Here are some easy rules to live by for a healthy mind ...

1. Meditate
   A 2015 study found that even a very short regular meditation practice may be an effective strategy for counteracting the cognitive decline associated with ageing.
   Just five minutes of sitting or lying while trying to calm your mind will help. Your stress levels will drop, your brain will breathe, you'll come out the other end more robust and ready to deal with challenges.
