I'm 59 years ago and up to about 15 minutes ago, have lived with my eating habits with the thought of being the only person to have such peculiar ways and habits.
I was always a fussy and picky eater. My family loved to eat all kinds of ethnic and gourmet foods. I went to the best restaurants. Growing up in Brooklyn I was exposed to every food imaginable. I HATED IT. I can tell you stories of how my father put wonderful food on my plate and I would start crying. By the time I was forced to put it in my mouth I was not only crying; but choking on it. Just the thought of the food made me sick. The SMELL. Those smells triggered my brain to say "no". I looked like a hamster with it's cheeks full. My father made me swallow it. I made sure it was in ity-bity pieces. If I ate slowly... then I wouldn't have to put anything else in my mouth.
My choice of food has not changed. I eat no condiments, no pickles, no salad dressings, no fish, no strange spices, no vegetables except carrots, lettuce, celery and potatoes. I like most common fruit. I know...... I'm missing a lot of good foods. I eat beef, pork and chicken grilled, fried, baked or rotisserie d.
The thought of eating something NEW sickens me. I smell everything. I think my sense of smell is sharper than normal. The sight of so many foods turns my stomach. My brain totally says no. At 59 years old I don't think there is anything that will change me.
