Eat Wholesome Foods:
Increase more fibre in the diet in the form of wholesome food, the way nature produces for us- unprocessed cereals, legumes, sprouts, fruits and vegetables with skin etc. Your half of the diseases will be prevented and cured like Diabetes, Cholesterol, Hypertension, Obesity and many more.
Fiber helps in many ways- absorbs maximum nutrients- resulting in less nutrient gaps, cleans small Intestine- preventing gut-related diseases like Gastritis, piles, IBS (Irritated Bowel Syndrome), Hemorrhoids, etc., releases sugar slowly in the Pancreas thus maintaining blood sugar levels preventing diabetes, inhibiting body to store on extra fats thus preventing obesity, cholesterol etc.
Nature has given ample of fibre to us in the form of the skin of the foods. We need 40 to 60 gms of fibre daily but with current food habits, polishing, refining, processing of the foods, etc. We get 5 to 12 gms of fibre only in regular diet, that means we have 8 to 10 times the deficit of fibre. The other reason is that because of too many pesticides and preservatives, people have stopped eating whole veg and fruits which you could get rid in simple ways.
Ways to remove Chemicals: Fruits are vegetables should be soaked in warm salted water to remove as many chemicals - pesticides, wax and preservatives, then washed with fresh water, towel dried and stored. Then you can cut, juice and eat/cook without washing again.
Remember: Washing the vegetables after cutting results in many important nutrients.
