Hi B.---If he is eating a healthy diet and a broad range of different kinds of foods, he is fine. His height and weight will be what it is supposed to be. Kids still have the inborn ability to stop eating when they are full. The instinctively know what is right for them in terms of calories. An optimal diets consists of mostly plants; fresh fruits, veggies, whole grains, legumes/beans, nuts and seeds. Minimize animal protein, and that includes milk, as those contain mostly saturated fat and calories, and too much animal protein is known to be a risk factor for degenerative disease. Please explore www.pcrm.org, enter dairy into the search box, and read The China Study by T Colin Campbell, www.chinastudy.com.
I am taking a series of wellness classes taught by a Naturopath who has her PhD in Nutrition. My passion is sharing the benefits of a plant based diet for optimal health and disease prevention. I have a couple of great charts that show how many servings are appropriate for children of different ages. I'd be happy to share those with you if you'd like.
You are right to avoid processed foods. They do not contain the nutrients needed for the body to be able to fight disease. Yes, they are ususally fortified, but nutrients from fortification DO NOT have the same effect in the body as do those from fresh fruits and veggies. Those are not so much food as they are food products. Sweets, or any treat for that matter, can be part of a healthy diet, but they need to be recongized as just that, treats. I can not have them in the house. If I do, they call my name from the kitchen and I am weak and all to ready to answer that call.
Just look at you and your husband's families. It will be very apparent on how big your kids will be...and as others have suggested, growth spurts happen differently for different people. If I can be of any additional help, please feel free to call. I have all kinds of great info that I am most happy to share. Be well, D.
PS. Through the unfortunate need for autopsies on little ones, they have found plaque deposits in kids as young as 2. A mother's diet has an impact on a baby even before it is born. If a 12 yr old complains of chest pain, you'd better take him to the ER as, yest, kids today are getting old people's diseases at younger and younger ages. It IS a shame...and I'm not here to blame anyone. It's just they way the standard american diet is today...we don't know what we don't know. I read an article once that stated food manufacturers produce about 3500 calories of food each day for every single American. That is why it is my mission to share the dangers of processed foods. So sorry about the soapbox...but it is that important to get the word out.
