A Healthy Diet for Type 2 Diabetes (2)

What is the connection between diabetes and heart and blood vessel diseases?

The connection is huge. It is said that diabetes is a cardiovascular disease. But lots of people haven't realized it yet. They worry more about diabetes affecting their eyesight and kidneys. Yes, that can happen. But the fact is that people with diabetes suffer and die much more from heart and blood vessel disease. That's the real issue.

This is the key reason there's been a big change in the focus of diabetes management. It's no longer just about glucose control. It's at least -- if not more -- important for people to focus on controlling blood pressure and blood lipids, particularly LDL cholesterol. By the time someone gets diagnosed with diabetes, he or she may have already been living with serious risk factors for heart and blood vessel disease for years.

What is prediabetes and what should people do if they're diagnosed with it?

Prediabetes is an in-between stage -- blood glucose is higher than normal but not high enough to fit the diagnosis of diabetes. The diagnosis of prediabetes should be a clear message that you're currently on the road to type 2 diabetes. If you don't take action now, you have a greater than 70% chance of developing type 2.

But this doesn't need to happen. Results from several studies, including the Diabetes Prevention Program, suggest that a small amount of weight loss -- 5% to 7% of your body weight combined with 150 minutes a week of physical activity -- can help slow down the progression. If you catch it early and do something, you can really have an impact on either preventing or delaying the onset of type 2.

What is the relationship between being overweight and type 2 diabetes?

It's a pretty direct relationship. About 80% of people with type 2 diabetes are overweight. Excess weight leads to insulin resistance, and insulin resistance leads to elevated blood pressure, abnormal blood lipids and diabetes.

Do people with type 2 diabetes need to eat snacks throughout the day to control their glucose?

No, but there's a lot of confusion about this. Experts used to tell people to eat snacks because the only medications we had to treat high blood glucose levels could cause the side effect of hypoglycemia, or low blood glucose. Regular meals and scheduled snacks were a way of limiting the problem. But now there are several newer medicines that lower blood glucose without that side effect. Plus, people have blood glucose meters and can check their glucose at any time.
If snacking is your natural way of eating, there's nothing wrong with one or two snacks a day. For instance, if a healthy snack in the afternoon -- like an apple and some reduced-fat cheese -- prevents you from being so famished at dinner that you gorge yourself, go ahead.
But people with diabetes should ditch the idea that they need to eat snacks. It can be counterproductive. Some people find all the snacks really inconvenient. Other people sit down for a snack and overeat, or they make unhealthy choices because they don't have anything better around.

Can people with type 2 diabetes eat sweets?

Yes, people with diabetes can enjoy sweets. There's an old idea that sweets are verboten for those with diabetes, but that's no longer correct.
It's true that the carbohydrates in sweets can raise your glucose levels, but an equal amount of starch would have similar effect. I don't think people with diabetes need to run around looking for sugar-free candies or insist that their families bake them sugar-free deserts.
However, you have to be smart about sugary foods and sweets. Sweets pack in a lot of calories and they tend to be high in fat, particularly in unhealthy saturated fat. So anyone with diabetes needs to be careful about how many they eat.
