My cravings seem to differ depending on a few factors such as time of day and what I've eaten recently. I find that right after I eat a full meal, I crave sweet food, possibly due to a conditioned response from our culture where we are used to having dessert after dinner. I would say that overall I crave savory foods and carbs like good breads. I have five younger siblings and each of us is completely different except for one unifying factor in our familial taste buds. We all hate fish. Every member of my household including my siblings and my mother hates fish. I think it's not too bad all the time, we all even enjoy other seafoods besides fish. This could be due to both the fact my mom never made many fish recipes and its likely her bias toward the food gave us a "bad taste" for it before we had tried it. I have worked in a few coffee shops and something that I know people get addicted to is coffee and sweets. I think because sugar and caffeine are such strong stimulants, it is the optional choice for a groggy brain that might crave these things. If my mom had shown signs of caffeine addiction, I would avoid caffeine in large quantities and possible other similar drinks that could prime my brain to crave a certain chemical. Having a healthy relationship to food is important to establish in children, and I believe it is a parent's job to know as much about themselves and their partner, including their biology, so that they may use that knowledge to prepare and lead their child. Children should be allowed to have access to foods they want in moderation while having a consistent and primary diet of healthy foods. In this way, while I am not addicted to any foods (to my current knowledge), I will introduce fish to my children because of it's many benefits to health. If they show the same distain than maybe the biology of liking fish is just not in our favor. Even before having children, you should prepare your body to produce a child by finding out what nutrients are essential to you and your individual metabolic needs. For example, many people are very low in Folic acid and take supplements before pregnancy, but food could also be used as prenatal care. Ensuring that you avoid teratogens, such as alcohol, and if you had suffered from NASH or fatty liver disease than you should also consider cutting out foods that produce acetate and cause intoxication. I do not normally drink, (I am over 21), me and my mother have very low tolerances for it and it makes us very sick which would have to due to how our genes encode the proteins that metabolize the alcohol. If I wasn't already an infrequent drinker, this would interest me and possibly sway me to abstain.
