Live Longer with Higher Fruit and Veggie Intake

Relationship of Fruit and Vegetable Intake to Mortality Rate... www.askthescientists.com 






Less than 5 servings/day of fruits and vegetables is associated with an increase in mortality rates.
Many observational and epidemiological studies have shown a solid relationship between increased fruit and vegetable (FV) intake and better health outcomes. However, the association between FV intake and overall mortality has seldom been studied in large cohort studies.

In a study published in the American Journal of Clinical Nutrition, researchers examined the dose-response relationship between dietary FV intake and mortality as it relates to both time and rate. The participants included 71,706 Swedish adults aged 45-83 years. Fruit and vegetable intake was recorded using self-administered surveys.

During the 13 years of follow-up 11,439 deaths occurred in this population. Researchers found that in comparison to those that consumed 5 servings of FV/day, lower FV intakes were associated with shorter survival and higher mortality rates in a dose dependent manner. Compared to adults that ate 5 servings of FV/day, adults who never consumed FV lived 3 years shorter and had a 53% higher mortality rate.

When fruits and vegetables were considered separately, people consuming at least 3 servings of vegetables per day lived 32 months longer than those who never consumed vegetables, and those who never ate fruit lived 19 months shorter than those that ate at least 1 serving of FV/day.

The findings of this study confirm the previously known benefits of eating fruits and vegetables and show that consuming less than 5 servings/day is associated with a dose-dependent decrease in survival and an increase in mortality rates.

5 Reasons Why You Need More Fiber in Your Diet


Fiber. Maybe you’ve heard it in conversations lately, or maybe you haven’t. (Believe me, it’s a pretty hot topic in the nutrition space.)

Whether you talk about Fiber or not, the bottom line is that most people need to increase their fiber intake to hit the recommended levels. Adequate dietary fiber levels for adults is 25 to 38 grams per day. Are your dietary habits within that range?

Higher amounts of fiber can be found in plant-based foods like fruits, vegetables, whole grains, legumes, nuts, and seeds. With the busy lives we lead, it can sometimes be challenging to get enough fiber from our food choices alone. Fortunately, USANA has an excellent fiber product called MySmart™Shake Fibergy Plus to help boost your fiber intake.



Let’s discuss some reasons why adequate fiber is an important diet goal and what some of the main benefits are.

Keeping it Regular

Alright. First thing’s first. Bowel regularity. There, I said it. Now let’s talk about it.

Fiber aids in normal bowel regularity, which helps move wastes and toxins out of the colon quickly and efficiently. If you don’t eat enough fiber or drink enough fluids, you could experience bowel irregularity (constipation). Not good.*

Growing up, my mother always referred to this concept as eating enough “roughage.” I won’t go into all of the details of those conversations, but the idea stuck with me. We need to eat foods high in fiber that will help clear us out and keep us healthy.*

This is probably the main concept that comes to mind when you think about fiber, but there are many other benefits too.
  
Get Both Types
Diets high in soluble and insoluble fiber are important for digestive health. But what does that mean? What is “soluble” and “insoluble” fiber?

SOLUBLE FIBER can be found in foods like oatmeal, nuts, beans, and fruit. It absorbs water and turns into gel in the digestive tract. This helps soften stool, making it easier to pass. Soluble fiber also has great benefits for heart health.

INSOLUBLE FIBER can be found in foods like whole-grains and vegetables. This type of fiber helps promote regularity. It also helps control hunger pangs, which we’ll discuss in more detail below.

 Fibergy Plus contains a blend of both soluble and insoluble fiber, so we’ve got you covered.

MySmart Fibergy Plus

Protect Your Most Important Muscle

Nope. I’m not talking about your biceps. Not your pectorals. Not even your glutes. Your HEART is the aim here.

Fiber not only promotes good digestive health but it is also important for the maintenance of heart health. Specifically, soluble fiber binds to cholesterol and helps remove it from the body.*
The FDA states that low-fat diets, rich in fiber-containing grain products, fruits, and vegetables, may reduce the risk of some types of cancer, a disease associated with many factors.*

The heart is one of the hardest working muscles in your body, so boost that fiber intake so you can take care of it better, and it will take care of you.

Feed Your Microbiome

Feed my what?! Don’t get freaked out. You may have heard about this. You have trillions of bacteria in your body at all times called the “microbiome.” In fact, many types of microbes are good for your body and even essential for basic functions like digestion.

You need to eat foods high in fiber to support these tiny, helpful organisms living within your body if you want to maximize the benefits they provide. Dr. Rhonda Patrick is a huge proponent to getting plenty of fiber in your diet to support these microbes:

“You also need to consume enough fiber on a regular basis so that the microbiome in your system is fed regularly. Most foods we eat (fats, proteins) are digested and absorbed fairly early on in the digestive tract. The microbiome is near the end of the digestive cycle, and they need food high in fiber that will make it to them.”

Feel Fuller Longer

Aside from these important benefits listed above, did you know that eating foods high in fiber actually helps you feel fuller, longer?

Do you find yourself snacking a lot throughout the day? If those are healthy snacks, like fruits and vegetables, then that probably isn’t a bad thing. But those healthy choices aren’t always within reach, so you might find yourself grabbing a sugar-filled option instead.

Try eating foods high in fiber during your main meals, and see if that impacts your snacking habits. Also, consider adding MySmart Fibergy Plus to drinks or even incorporating it in the food you eat. The high fiber content will leave you feeling satisfied, making it easier to skip unhealthy snacks throughout the day.




Eating a diet high in fiber should be a priority on your Nutrition To-Do List. To ensure you’re hitting those fiber goals, MySmart Fibergy Plus is a great addition to keep on-hand.

How do you make sure that you’re getting enough fiber? What are some tasty ways that you add Fibergy to your recipes for a fiber boost?

7 Steps to Detox Your Body, Mind, and Lifestyle




Summer is around the corner. Are you ready?

If you’re still stuck in hibernation mode from the long winter, you’re not alone. But now is a great time to detox your body, your mind, and your lifestyle to set yourself up for an active and enjoyable summer. Here are seven steps to better health and a renewed sense of vitality to make the most out of the sunny months ahead.

Quick quiz: do you feel thirsty right now? If you do, you’re dehydrated. Water has so many amazing benefits: it helps control calorie intake, energizes your muscles, keeps your skin looking beautiful, and keeps those bowels working properly (hey, it’s important). If you’re not a fan of plain water, infuse flavor by mixing in your favorite fruit, like strawberries and blueberries or lemons and oranges, or mix in some veggies, like cucumber slices.

2. Eat more of some foods.

Asparagus, for example, contains amino acids and minerals that can help protect liver cells against toxins. And beets contain an antioxidant that can help support the cells in the liver. Check out this super simple asparagus recipe and these ways to add beets into your weekly diet.

3. Eat less of others.

 Okay, so alcohol isn’t a food, but if you’re trying to detox, you’ll want to avoid it. Same with too much salt; the body needs small amounts of it to function, but too much can lead to high blood pressure, water retention (read: bloat), and other issues. And did you think I’d let you get away with processed sugar? Nope. Try to minimize your intake. Stick to natural sugars from fruit and leave the baked goods and sweets for special occasions (and I’m not talking about Fridays, I’m talking about birthdays and weddings).

4. Get moving.

This should already be a staple of your everyday life, but if you’re not super active, just get outside and walk around the neighborhood after dinner each night. Not only can regular walks help you maintain a healthy weight and strengthen your bones and muscles, but it can also improve your mood. Major bonus.

5. Hit the hay.

And by that I mean make sure your head is hitting your pillow at least seven to nine hours a night. A proper night’s sleep can work wonders on your mood by lowering your stress levels, among other benefits. If you have trouble getting to sleep, make sure your bedroom is cool and dark, and try taking a shower right before your target bedtime.

6. Clean up your living space.

Detox doesn’t just take place in your body and mind—it also includes your surroundings. Spend some time decluttering your closet and getting rid of the things you don’t need anymore. Open your windows and let fresh air in. Organize that junk drawer. Decluttering has great benefits, but my personal favorite is taking back that feeling of control over your life. Your things don’t own you! Get rid of the excess and you’ll gain so much more in return.

7. Support your healthy diet with high-quality digestion and detox supplements.

Even if you’re eating a healthy diet, it can be difficult to get all nutrients your body needs from food alone. Aim for optimal nutrition with supplementation rather than simply skating by with the Recommended Daily Allowance (which is a minimum to prevent nutrient deficiency). The USANA Digestion & Detox Pack, along with the CellSentials™, made with InCelligence technology offers our best products to support your efforts for a renewed sense of well-being.* The pack is specially put together to last you 28 days—perfect for a pre-summer detox.

Challenge yourself to build some of these healthy habits into your daily routine for a healthier, happier summer—and beyond!

Did you know that poor dental health can increase your risk of heart disease, respiratory infections, and possibly even affect your mental health?

In addition to a great smile, good dental health is essential for overall health.

The science regarding the connection between poor dental health and a negative impact on health and various diseases is becoming clearer in recent years. Periodontal diseases increase the prevalence of diabetes, rheumatoid arthritis, atherosclerosis, myocardial infarction and stroke, to name a few. This typically involves local periodontal inflammation that may increase levels of systemic inflammatory mediators, resulting in promotion of atherosclerosis and insulin resistance. A potential link between obesity and periodontitis has also been shown.

Here are some facts you know about dental health –
• People with gum disease are almost twice as likely to suffer from coronary artery disease compared to people without periodontitis.
• Some research has shown that people with poor dental health resulting in tooth loss may have an increased risk of dementia.
• People with diabetes are more likely to have periodontal disease. Gum disease can make it harder to control blood sugar, so treating gum disease may help improve diabetes symptoms.
• Gum disease may increase your risk of getting respiratory infections, such as chronic obstructive pulmonary disease (COPD) and pneumonia, according to the Journal of Periodontology.
• Poor dental health and gum disease has even been related to decreased fertility and increased risk of miscarriage.

Aside from proper brushing, flossing and physical dental care, prevention and treatment of periodontitis require a healthy diet that includes sufficient antioxidants, vitamin C, vitamin D, and calcium.

From Deanna:  I get my supply of antioxidants from USANA's CellSentials, often adding extra vitamin D and Calcium Plus.  USANA's toothpaste made a huge difference to the health of my gums.

Are You Sleep Deprived?

Sleep Deprivation May Increase Food Intake and Promote Obesity

It is known that short-term sleep deprivation increases plasma concentrations of ghrelin (a hormone related to increased appetite) and decreases concentrations of leptin (a hormone related to satiety).  

In a randomized crossover study, researchers studied twelve normally healthy non-obese men to observe the effect of sleep deprivation on energy intake and physical activity.

During the first night of each 48-hour session, subjects had either 8 hours (from midnight to 8:00 am) or 4 hours (from 02:00 am to 06:00 am) of sleep. All foods consumed thereafter (jam on buttered toast for breakfast, buffet for lunch, and a free menu for dinner) were eaten ad libitum (with no restrictions). 

Physical activity was also recorded. Sensations of hunger, perceived pleasantness of the foods, desire to eat some foods, and sleepiness were also evaluated.

In comparison with the 8-hour sleep session, subjects consumed 559 (22%) more calories on the day after sleep restriction, and hunger was higher before breakfast and dinner. Researchers observed no change in the perceived pleasantness of the foods or in the desire to eat the foods. 

Physical activity was slightly higher after sleep restriction than after 8 hours of sleep, even though the sensation of sleepiness was more apparent.

In this group of healthy men, one night of reduced sleep led to an increase in food intake and, to a lesser extent, physical activity-related energy expenditure. Although further research is needed to confirm the results of this small study, these results suggest that sleep restriction could be a factor that promotes obesity.

Vitamin D Supplementation Slows Age-Related Bone Loss in Older Women



Until recently, it was unknown whether improving vitamin D status (without changing calcium intake) could have a positive effect on bone turnover. To that end, a group of researchers recently measured the effect of vitamin D supplementation on markers associated with bone turnover in women known to be vitamin D deficient (<20 ng/mL).

Participants were South Asian women at least 20 years of age. The women were categorized by age and menopausal status, then randomized to receive either 4,000 IU of vitamin D or a placebo every day for 6 months.

In the women who received vitamin D supplements, average vitamin D blood levels increased from 8.4 ng/mL (21 nmol/L) to 30 ng/mL (75 nmol/L). Additionally, measured chemical markers indicating bone loss either remained the same or decreased in postmenopausal women who received vitamin D supplements, indicating a reduction in bone turnover.

This research confirms that correcting vitamin D deficiencies in older women can suppress age-related increases in bone turnover, which also helps reduce bone resorption (the process by which bone breaks down and releases its minerals, resulting in a transfer of calcium from bone into the blood).
