For many of us, New Year's is when we commit (or re-commit) to healthier eating habits.
To help us get ready for a fresh start after the holidays, we rounded up some of our favorite diet tips of the past year and talked about them with Christine Sharp, MS, RD, LDN, CNSC, a clinical dietitian at Rush University Medical Center.
If you think low-fat or fat-free products are better for you, check their labels. You might be surprised.
"Some reduced-fat peanut butters and low-fat dressings have more calories than regular because of all the added sugar," Sharp says — a problem because added sugar is a major contributor to the risk of cardiovascular disease, according to a study in JAMA: Internal Medicine.
"Adding sugar to low-fat products is all about trying to make up for the taste that's lost when you take out fat," Sharp points out.
According to a number of recent studies, moderate portions of even saturated fats like butter don't increase the risk of heart disease as once thought. So if you can limit yourself to reasonable servings of full-fat products, go ahead and enjoy them.
Juicing is trendy these days, but you're much better off eating whole fruits and vegetables.
"When you juice, you get rid of all the good fiber that helps you feel full," Sharp says. "In general, fruit and vegetable juices don't give you that satiated feeling even though they have lots of calories, because they don't contain any protein."
Her suggestion: Make a smoothie using whole fruits and vegetables plus protein like Greek yogurt (which has twice the protein of regular yogurt), milk or tofu.
People who get healthy amounts of sleep (at least seven hours a night) have an easier time maintaining a healthy weight.
There are a lot of reasons: First, when we're sleep-deprived, we tend to eat more overall and eat food that's less healthy — in part because sleep deprivation reduces activity in the brain's frontal cortex, where our rational decision-making (e.g., choosing to exercise, choosing healthy foods and practicing portion control) happens.
Sleep deprivation also affects the hormones ghrelin and leptin. Lack of sleep increases ghrelin levels (which leads to hunger and influences the body to use less energy and retain more fat) and decreases leptin, a hunger-controlling hormone.
You know that eating your fruits and veggies is good for you — but they can literally make you feel good, too.
The journal BMC Medicine recently published a study showing that a diet made up mostly of vegetables, fruits, legumes and nuts can decrease your chances of depression, while foods like processed meats and sugar-heavy treats contribute to depression. Even moderate dietary changes significantly reduced study participants' risk of developing depression.
All foods can fit into a healthy lifestyle if you follow good portion-control habits and make sure your overall diet is well balanced.
Did you know that there's a diet that may help protect your brain as you age?
The MIND diet, developed by researchers at Rush, was found to reduce the risk of developing Alzheimer's disease and may also slow cognitive decline.
The diet involves eating 10 "brain-healthy" food groups — including green leafy vegetables, nuts, berries, beans, fish and olive oil — while avoiding five "unhealthy" groups (red meats, cheese, fried or fast foods, etc.).
Berries are the only fruit specifically to make the MIND diet. Blueberries are one of the more potent foods in terms of protecting the brain, and strawberries have also performed well in past studies of the effect of food on cognitive function. Fresh berries make a tasty topper for yogurt, oatmeal and whole grain cereal; and you can easily throw a handful — fresh or frozen — into the blender for a naturally sweet smoothie.
Make grocery shopping fun to keep yourself out of a boring food rut:
Don't think about the color red for the next five minutes, no matter what.
Is your brain now overflowing with images of stop signs, strawberries, lipstick and clown noses?
Same thing happens with "forbidden" foods, says Sharp. "If you forbid yourself to eat a brownie, next thing you know you'll be eating the whole pan because you feel deprived and can't think about anything else."
All foods can fit into a healthy lifestyle if you follow good portion-control habits and make sure your overall diet is well balanced. A suggestion for dealing with those brownies: Cut into controlled portions, wrap individually and freeze to enjoy one at a time.
Spend a few minutes watching a TV medical show or leafing through magazines in the grocery checkout line and you'll be inundated by often conflicting, frequently confusing diet advice.
For sound information and ideas for changing up your food routines, make an appointment to consult with a dietitian.
"There's always something new to learn — anybody who needs suggestions for healthy, interesting ways to improve their diet should come in for a conversation," Sharp says.
