Eat like your granny did is very good advice         

Granny (think cardigans, midi skirts, pearl earrings, slides and ladylike structured bags)  Eating like your grandmother—or even better, your great-grandmother—is a long term strategy worth considering, especially if you are getting tired of getting confused about which "miracle"  diet to follow and trying to make out the complicated ingredient lists on packaged foods. Try not to eat anything your great-grandmother wouldn’t recognize as food. 

Eat real, unprocessed food. Mostly plants. Steer well clear of processed foods and man-made ingredients such as hydrolyzed vegetable proteins and oils, trans fats and other “edible food-like substances” found on today’s supermarket shelves. Another simple interpretation could be avoid eating anything out of a packet, especially those which contain numbers posing as ingredients or cryptic words you can’t pronounce. If you can't pronounce it don't eat it.

Our grandmothers had it right. I remember as a kid my great grandmother serving up a very simple and healthy meat and three veg. Gran ate a diet rich in plant-based wholefoods with generous amounts of fresh fruit, vegetables, cultured foods, nourishing broths as well as a little quality protein. She lived to the ripe old age of 100. My philosophy has always been: keep it simple, keep it fresh, buy organic and local, make it yourself and know exactly what’s in the foods you eat. Ingredients and additives such as gums, MSG, thickeners, hydrogenated oils, emulsifiers, and stabilisers should not be on the menu.
The best granny-approved wholefoods are fresh seasonal fruits and vegetables that you can get from your local grocer or farmers market. 
Keep your pantry stocked with a good quality extra virgin olive oil,  ghee, mustard, raw honey, vinegar, unprocessed sea salt, white pepper and dark rye bread.  Here is one of grannies recipes to help you detox after a holiday celebration.
