Should You "Go Nuts" To Prevent Type 2 Diabetes?

Obviously, not everyone should eat nuts to prevent type 2 diabetes. Some people simply can't eat nuts because they are allergic to them.

If you have experienced any of the following symptoms after eating nuts, or if your doctor has used these terms to describe your symptoms after eating nuts, you shouldn't try eating nuts to prevent type 2 diabetes.

• Abdominal pain
• Angioedema (especially if presenting as a swollen throat)
• Cardiovascular collapse (extremely slow heartbeat, or extremely fast heartbeat with fainting or extreme weakness)
• Cough
• Diarrhea
• Dysphonia (inability to hear)
• Dyspnea (shortness of breath)
• Feeling of impending doom
• Flushing, redness of the face
• Nasal congestion, nasal pruritus (itching), rhinorrhea (runny nose), and sneezing
• Nausea
• Ocular injection, ocular pruritus (itch), conjunctival edema (swelling in the eyelids), periocular swelling (swelling around the eyes)
• Oropharyngeal pruritus (itching in the mouth and throat)
• Stridor (noisy breathing)
• Urticaria (hives)
• Vomiting
• Wheezing

It's also possible to have a relatively mild allergy to nuts, so mild there aren't any noticeable symptoms when just a few nuts are consumed, that nonetheless can cause serious symptoms when larger amounts of nuts are consumed on a regular basis. 

It is always a good idea to start changes in your diet slowly. Unless you already know you don't have an allergy to nuts, eat maybe a few kernels one day, a few more the next day, building up to the recommended 1-1/2 to 3 ounces (43 to 84 grams) in about a week.

If you are allergic to other nuts, it is highly likely you are allergic to pistachios. So what's the food that makes a difference in the progression to diabetes if you can't eat nuts?

Another study in which Dr. Bulló participated suggests that a Mediterranean diet fortified with generous amounts of extra-virgin olive oil may be as good, or even better.

The  Prevención con Dieta Mediterránea Trial, which ran from 2003 to 2010, found that volunteers who ate large amounts of extra-virgin olive oil were 15 to 57% less likely to develop type 2 diabetes than volunteers who did not.

The data suggested that consuming both kinds of healthy fat in large amounts might even increase the risk of diabetes.

However, adding these kinds of fat to an otherwise healthy Mediterranean diet, including lots of vegetables, not a lot of fruit, daily servings of fish or pork, small amounts of sourdough bread, and very few sweets, did not cause weight gain. And when only the consumption of olive oil was encouraged, calorie consumption didn't make a difference in whether people became diabetic.

Neither did weight.

Preventing the progression of type 2 diabetes doesn't have to be all about losing weight and cutting out the fat. It can be about eating all you want of foods that are inherently good for you. Both nuts and olive oil are inherently good for you, assuming you don't have allergies, but focus on one, don't try to add both on a daily basis. It is not necessary to exclude olive oil if you are eating nuts for your health or vice versa, but don't make both healthy foods a daily habit.
