Diet After 50: Food Choices & Exercise Prove Critical

For adults age 50 and over, making healthy food choices and staying active are crucial lifestyle habits. Recent studies show that a good diet can not only help you resist illness and prevent certain diseases, but also defy or delay some of the common effects of aging.

“We need fewer daily calories as we age because our metabolism naturally begins to slow,” says MPCP Arnold physician, Amanda Malone, M.D. “Since you don’t need as many calories, those calories you do consume become very important. Your diet after age 50 should include a variety of healthy, nutrient-dense foods. Add in daily exercise and you’re on the path to a higher quality of life and enhanced independence as you age,” she adds.

Body Changes & Diet Needs

As we all know, our body changes with age. There is a reduction in muscle, an increase in body fat, and your total body water decreases by up to 20 percent. You need fewer calories than you did at a younger age since your basal metabolic rate decreases as muscle mass declines.

The good news is that moderate exercise helps preserve muscle mass and can slow the rate of this process. Of course, regular exercise has other benefits, including cardiovascular fitness, bone strength, better mobility and balance, as well as feelings of well-being. Dr. Malone adds, “Try to include exercise that increases lean muscle mass, like weight training. And consider yoga or pilates, which are great for flexibility and boosting your metabolism.”

Another effect of aging is that the body becomes less efficient at absorbing vital nutrients and minerals from our diet– including calcium, vitamin B and folate. Certain medications can also affect appetite, or block absorption of some vitamins and nutrients.

So, what should we “over 50s” do?

1. Make calories count.

“When patients ask ‘How many daily calories do I need?,’ I tell them it depends on how active they are and where their calories are coming from,” says Dr. Malone. Just counting calories isn’t enough for making smart food choices, but here are some general guidelines for maintaining (not losing) weight:

A woman over 50 who is:
-not physically active needs about 1600 calories a day
-somewhat active (housework, yard work, etc.) needs about 1800 calories a day
-very active (exercises regularly 30 mins. or more most days) needs about 2000 calories a day

A man over 50 who is:
-not physically active needs about 2000 calories a day
-somewhat active needs 2200-2400 calories per day
-very active needs 2400-2800 calories daily

These calories should come from a variety of fresh fruits and vegetables (5 a day when possible), unprocessed grains, and good sources of protein. To include more high quality protein in your diet, try replacing red meat and processed meat with fish, skinless chicken and turkey, low-fat dairy, and plant-based protein like beans, nuts and seeds.

“A variety of foods is best because you’ll have several sources of required vitamins and you won’t get bored by the same foods. Also, the more ‘whole’ unprocessed foods you can eat, the better. Go for the whole fruit, not fruit juices. Go for fresh, grilled or baked chicken, not processed lunch meat,” says Nurse Practitioner, Rachel Sweeney, of MPCP Arnold.

Also, if you are trying to maintain- or lose weight- keep track of daily calories with a food diary or a free app, such as myfitnesspal.com.

2. Drink water & eat more natural fiber.

As we age, we can become more prone to dehydration. Post a note in your kitchen reminding you to sip water throughout the day and to drink water with meals. Nutritionists say in general that 3-5 large glasses of water a day is adequate after age 50…you don’t need to go for 8-10 as we often hear. Make drinking more water a daily habit and you will help keep your mind sharp, and body regular. Staying hydrated keeps skin looking younger too!

Dietary fiber also helps keep the body and bowels regular, but can do much more, such as lower your risk of heart disease, diabetes, and certain cancers. Women over 50 should aim to eat at least 21 grams of fiber a day, and men over 50 at least 30 grams per day. Good sources of fiber include whole grains, oatmeal, beans, and uncooked fruits and vegetables like carrots, apples and berries.

3. Don’t skip meals.

While it’s okay to skip meals occasionally, regularly missing meals or heavily restricting calories is unhealthy. Nutritionists advise those over 50 to eat three meals a day, or to break meals up into 5 smaller meals.

“Skipping meals causes our metabolism to slow down, which affects energy level and usually doesn’t help with weight loss,” says Rachel Sweeney, CRNP. “When we skip eating, our blood sugar levels drop, but they can surge again when we eat a big meal. This yo-yo effect is unhealthy and it’s much better to keep our blood sugar levels more even throughout the day with regular, healthy meals.”

Starting the day with a healthy breakfast gets your body going and is a good way to get some fruit, fiber and protein in your diet. Try yogurt topped with bran cereal and berries, or a veggie-packed omlette, peanut butter on whole grain toast or old-fashioned oatmeal with walnuts and fruit.

Snacking is okay as well to tide you over and keep your energy up during the day. Choose healthy options like almonds over chips and fruit instead of cookies. Other good snacks are a slice of cheese and whole grain crackers, veggies and hummus, and even a small cup of soup.

4. Read labels, and cut added sugar and sodium.

While it takes a bit more work, reading food labels can definitely help you make better food choices. Labels break down how much protein, carbohydrates, fats, sodium, key vitamins and minerals, and calories are in a specific serving.

Each label also has an ingredients list, which lists the ingredients from largest amount to smallest. Once you start reading labels you’ll be surprised how many foods list sugar or high fructose corn syrup as the first (largest) ingredient! Sugar is added to many of our foods to enhance the flavor, but many are crediting all the sugar in our diet to the obesity epidemic. Sugar may also cause inflammation in the body, so limiting it is good not only for weight control, but also possible disease prevention.

Reducing sodium (salt) will help prevent water retention and high blood pressure. Look for “low-sodium” options when shopping or try to season meals with herbs and spices other than salt.

5. Be cautious about supplements.

If you are over 50, some of the key vitamins and minerals you should get enough of are vitamin B12, vitamin D, folate and calcium. It is better to meet your needs through diet, but these are so important that you might want to consider taking supplements. Talk to your doctor about which, if any, supplements you need and don’t overdo it. High doses of certain supplements can be harmful, especially if you are on medications.

6. Stay Active!!

The benefits of exercise throughout your life can’t be over-stated. But as you age, even moderate exercise has been proven to add years to your life—and to make those years more enjoyable and independent.

“Regular exercise slows the effects of aging and many age-related disorders such as diabetes, stroke, cardiovascular disease and osteoporosis,” says Dr. Malone. “But that’s only the tip of the iceberg. We know that exercise reduces the risk and seriousness of falls and fractures, keeps our minds sharp, and encourages social interaction,” she adds.

It’s never too late to start exercising either. Start slow– take the stairs instead of the elevator, keep carrying your groceries, and try a new exercise class. As always, talk to your doctor about an exercise plan, and which activities you should consider given your age and current health status.

Can We Boost Our Immune System?

by Garth Ashbeck, M.D.

immune3The latest science on staying healthy.
Visit your local pharmacy, page through a magazine, or browse online and you’re sure to see products promising to boost your body’s immune system. Everything from echinacea, ginseng, probiotics to mega-dose vitamins – claim to help prevent or cure disease. But is there enough science to prove we should hop on the immune-supplement bandwagon?

“There is no simple answer for now,” says Dr. Garth Ashbeck of MPCP’s Pasadena practice. “While there are studies that show benefits to antioxidants, probiotics and some supplements, there needs to be more research into whether we can truly alter- or boost- our immune system. Regulatory statements cannot then be made to currently support or refute these supplements, he adds.

The main problem is that our immune system is just that: a complicated, biological system. There are many different kinds of immune cells that respond to various threats on the body in different ways. So, if you want to boost your immune system, which part should you boost, and by how much?

On the whole, our immune system does a remarkable job of protecting against harmful microorganisms. But, sometimes it fails and you get sick. Researchers are trying to find out how we can alter this path, and in addition to studying the effects of supplements and other agents, they are looking closely at the link between lifestyle and better immune function.

“We can’t underestimate how a proper diet and enough sleep, for example, affect our health, so we feel the best way to currently keep our immune system strong is by controlling key lifestyle habits, “ says Dr. Ashbeck.
Here are some general guidelines for helping your immune system based on the latest science:

Eat a varied, healthy diet
There is lots of research about the diet-immunity link. While some dietary supplements have been found to alter components of immune function, there is no firm evidence that they actually bolster immunity to the point where you are better protected against infection or disease than by eating a varied, healthy diet.

For example, scientists have found that too much dietary sugar may curb immune system cells that help control bacteria, and cause inflammation in the body. Again, this is just one small part of a complicated system, but cutting down on sugary drinks and other sugary, or processed foods, is definitely recommended.

Eating a variety of fruits and vegetables, which are rich in nutrients like vitamins C and E, plus beta-carotene and zinc, is a good choice as well. Go for a wide array of brightly colored fruits and vegetables, including berries, citrus fruits, kiwi, apples, red grapes, kale, spinach, sweet potatoes, and carrots.

“Even though we don’t know exactly how diet affects immunity, there are clearly benefits to eating healthy. For example, eating cruciferous vegetables can boost the liver’s ability to flush toxins from the body,” says Dr. Ashbeck. “And some researchers are studying how the bacteria in our stomach’s and digestive system can affect immunity and health, so there is much on the horizon.”

If you have questions about taking certain vitamins or dietary supplements, talk to your doctor first.

Get Enough Sleep
You may have noticed you’re more likely to catch a cold or other infection when you’re not getting enough sleep. While some consider it an old wive’s tale that lack of sleep will make us sick, some data is showing that sleep does help immune function. People with sleep disorders or extreme lack of sleep have shown a decrease in adequate development of protective T-cells and higher levels of certain stress hormones in recent studies. Although researchers don’t yet understand the exact link, it’s clear that our brains and bodies perform better with adequate sleep – usually seven to nine hours for an adult.

Exercise and Control Weight
Try to get regular, moderate exercise on a daily- or at least 5 times a week- basis. Even a 20-minute daily walk can improve your fitness and may help your immune system fight infection. “It makes sense that a strong body and effective circulatory system will help you fight illness and disease,” says Dr. Ashbeck. “We also know that exercise can boost your body’s feel-good chemicals and help you sleep, both of which are good for immunity.”
Exercise can also help you control or lose weight. There is direct evidence linking obesity to disease, including diabetes, heart disease, cancer and other illness. If you are overweight, even losing a few pounds puts less stress on your body’s organs and function, which includes your immune system.

De-Stress
Everyone has some stress; it’s part of life. But if stress drags on for a long time, it seems to make you more vulnerable to illness, from colds to serious diseases. Chronic stress exposes your body to a steady stream of stress hormones that could suppress the immune system. You may not be able to get rid of your stress, but you can get better at managing it:

  • Learn to meditate.
  • Slow down.
  • Plan for some “You” time in your day.
  • Connect with other people.
  • Work out to blow off steam.

Other lifestyle choices that may have a direct impact immunity include quitting smoking, controlling your blood pressure, drinking alcohol only in moderation, and taking steps to avoid infection, such as washing your hands frequently and cooking meats thoroughly.

While there may not be a magic pill to prevent disease, you can start making practical lifestyle changes now. They will not only improve your overall health, but will also help keep your immune system strong and working hard to protect you. Also, talk with your doctor about screenings, vaccines, the right medications, and other ways to stay on the road to health.

A Healthier Weight: 3 Key Steps

qa-160Q & A with Dr. Falana Carter of MPCP, Arundel Mills

Q: What are the key challenges for patients who struggle with weight?

A: Given the demands of family, career, and social responsibilities, it’s no wonder many people find that their health is pushed to the end of the priority list. I tell patients who struggle with obesity that there are 3 simple steps to improve their cardiac health, lower cholesterol, and reduce BMI (Body Mass Index) through lifestyle changes:

    1. Eat 3-4 meals daily – don’t skip any meals! When you skip a meal, you slow your metabolism down – your body needs to eat every 4-6 hours.
    2. Exercise – schedule it into your daily routine.
    3. Be “selfish” for your health.

Q: How do you start the conversation with patients who need to lose weight?

A: As part of their exam, I ask, “So what are you doing for exercise?” Often patients tell me they don’t have time to exercise; this is where I encourage them to be selfish. If you set aside a regular time to exercise, and let your family and friends know, they’ll respect that schedule and not distract you from your goal.

Q: In addition to eating on a regular schedule, how big a part does nutrition play?

A: Nutrition plays a central role. I emphasize the importance of eating healthy – more protein, healthy snacks; less sugar and processed foods. I also recommend using myfitnesspal.com, a free online weight loss tool. And for patients willing to share their password, there’s even the capability for their doctor to see what they’re eating, and provide feedback and guidance in their weight loss process.

Q: How are you incorporating these principles into your practice

A: Soon, the Arundel Mills office will launch a program dedicated to improving patients’ health through lifestyle changes, so we’re excited about this opportunity to help more individuals achieve their goals.

Vitamin D Is Key — Are You Getting Enough?

by Jerry Levine, M.D., FACP

We have long known the positive effect of Vitamin D on bone health, but research is showing that this star vitamin has links to numerous health benefits — and that many of us may be Vitamin D deficient. “It’s exciting to review the studies available on Vitamin D. While Vitamin D has proven important for bone strength and prevention of osteoporosis, adequate levels may also reduce the risk of heart disease, stroke, diabetes and some cancers. Understanding this disease-fighting role is new. So, I’m talking to my patients more about Vitamin D food sources and supplements.

There are a few unique facts about Vitamin D that make it hard to ensure you’re getting the right amount:

  • Very few foods naturally contain high levels of Vitamin D. Fatty fish and eggs are a source, but most of our Vitamin D comes from dairy products, cereals and orange juice which have been fortified with Vitamin D. So, getting Vitamin D at breakfast is a good start.
  • Vitamin D is processed by our bodies through exposure to sunlight. That was fine when people used to work and be outdoors more often, but in modern society many people sit behind a desk most of the day, or live in a climate that doesn’t get much sun at certain seasons. Getting outside for even a 15 minute walk a day will help your body absorb Vitamin D, but that may not be enough.
  • Taking a Vitamin D supplement is recommended for most adults. However, there is some debate about how much, so I talk to my patients individually and consider age, lifestyle, diet, disease profile, etc. to come up with the right daily amount. If I’m concerned that a patient is Vitamin D deficient, we can order a simple blood test.

It is estimated that up to 40% of adults are Vitamin D deficient, particularly in northern climates. However, with all that we know about the “sunshine vitamin’s” role in building muscle and bone (especially when taken with calcium), and potentially reducing cancer cell growth and protecting the heart and other organs, we should be making it part of our daily health regimen.”

Talk with your MPCP doctor to find out more about diet, Vitamin D and other appropriate supplements.
