Foods which have man made chemicals such as preservatives, insecticide residues, conditioners, artificial colors or genetically modified organisms in them, will be a challenge for the liver to break down properly and neutralize the impurities.
Also, any foods which the person may be allergic or sensitive to, would be bad for the body in general. Excess alcohol should also be avoided. Fats and oils that have been highly processed or had chemicals added to them are also bad. Cold pressed, organic oils and some natural saturated fats, are good for the liver such as coconut oil or fats found in meats from animals that are grass fed and free from antibiotics. All highly processed foods which have become devoid of the natural vitamins and minerals and other nutrients normally found in fresh foods, are generally not good. Organic foods are best, and one should strive to eat them as fresh as possible. Beets, pine nuts and artichokes are especially good for the liver and helps the bile flow freely, rather than congeal and cause blockages.

It is normal. If you feel guilty about it, that’s also normal. Obviously it depends on the individual. Some boys blossom early and some don’t. I know a few teenage boys who do not have to present their I.D. before they are allowed into a club However, don’t be fooled by their looks. Mentally they are immature. It may be normal to be attracted to them, but acting on this, is not.
