Home cooking: Good for your health

Can you imagine if you went to your primary care doctor’s office for cooking classes? What if your visit included time spent planning meals, discussing grocery lists and the benefits of home cooking, and learning culinary techniques?

If that sounds odd to you, it shouldn’t.

We already know that the more people cook at home, the healthier their diet, the fewer calories they consume, and the less likely they are to be obese or develop type 2 diabetes. A growing body of scientific evidence supports teaching patients how to cook meals at home as an effective medical intervention for improving diet quality, weight loss, and diabetes prevention.

In fact, research is turning to studying the value of nutrition programs that include cooking instruction. These programs have been shown to help people adhere to a healthier diet, eat smaller portions, and lose weight — improvements that lasted as long as a year after the study ended. These programs can even help patients with type 2 diabetes to eat healthier, lower blood pressures and blood sugars, and lose weight. Hard to believe it, but time in the kitchen can be as valuable as medication for some people with diabetes.

I recently met with a lovely patient of mine,* She has type 2 diabetes, and has trouble eating a healthy diet. Most of her meals are frozen dinners or takeout, which is all highly processed food with little nutritional value. I asked her if she would like to consult with a nutritionist.

“I have, many times,” she laughed. “They’re all very nice and everything, and it’s all good information, but I can’t cook. I get to the produce section of the grocery store, and I don’t know where to start.” Aha. No surprise, then, that multiple studies have shown that home cooking instruction significantly increase a person’s confidence in his or her food preparation skills, which translates into eating a healthier diet.

Diet and lifestyle interventions have already been shown to be quite effective for weight loss and prevention of type 2 diabetes, and adding a home cooking instruction component could be even more powerful.

Let’s get cooking!

    I love soup, and it is healthy too. Bone-marrow soup is among the most healthy soups. I found this site about various alternative health products that I have tried and they work. I believe in alternative health supplements if they are organic with pure ingredients.

    Home cooking is the best thing you can do for your health. The recipe above is exactly why people don’t try to cook because it looks so complicated and scary. There are so many simple 3-5 ingredient & 1-2 step recipes that make it easy to get into cooking. Don’t give up trying.

    That should be “healthy cooking”

    Many state extension service offices and even some community colleges offer cooking classes. The former, in particular, is pretty responsive to user/community requests for particular types of classes/instruction that fall w/in state extension service services–my local extension service office has offered classes in health cooking, including adaptation of “traditional” dishes/meals to be healther, food preservation techniques, buying/how to choose fresh veg & fruit, etc.
    Far as I know, every county has an extension service office, even suburban/urban counties.

    Some places of worship may also offer classes in cooking/healthy cooking, if members of the congregation feel there’s a need/interest, and there are people willing to organize the classes.
