Vitamin D: millions of Americans take it and most should just stop

Published

on

Americans love a quick health fix in pill form: something to protect against illness, with minimal effort. For years, one of the go-to supplements has been vitamin D, thought to do everything from preventing cancer to strengthening bones.

Some bad news: Yet another big study adds to the pile of evidence that it’s useless for most people.

The new research, published in the New England Journal of Medicine, was a much anticipated nation-wide randomized, placebo-controlled trial on whether vitamin D supplementation prevents cancer and cardiovascular disease among older men and women.

The findings of the study were unequivocal: “Supplementation with vitamin D did not result in a lower incidence of invasive cancer or cardiovascular events than placebo.”

The new research follows another recent meta-study in the journal Lancet Diabetes & Endocrinology, which looked at 81 randomized trials on whether vitamin D prevents fractures and falls, and improves bone mineral density in adults. The authors of that review also found no benefit on musculoskeletal health.

“Something like 40 percent of older adults in the US take vitamin D supplements because they think it’s going to prevent against fractures and falls or cancer,” said Alison Avenell, the clinical chair of health services research at the University of Aberdeen and an author on the Lancet study, “and we’re saying the supplements for fractures and falls aren’t going to do that.”

This research builds on previous meta-studies and the large-scale randomized trials that have shown the fat-soluble hormone doesn’t prevent fractures and may not have a role in preventing cancer, but can increase the risk of kidney stones when taken along with calcium.

Of course, there are some cases when supplementation can be helpful: During pregnancy, for example, or for people who have been diagnosed with health conditions that may lead to vitamin deficiencies, like liver disease or multiple sclerosis. People with asthma, those don’t get into the sun at all (like the homebound or institutionalized), or those from ethnic backgrounds with darker skin — African, Afro-Caribbean and South Asian — may also benefit from a supplement.

But for a health boost in most people with no symptoms of deficiency, the tablet shows such little utility that doctors are even questioning why we bother measuring vitamin D levels in those who aren’t at risk. Most of us actually get enough vitamin D without even trying.

So why all the hype about vitamin D?

The hype about the vitamin during the past two decades started with early vitamin D science. Before researchers run randomized controlled trials, they often look for links between health outcomes and exposures in large-scale population research called observational studies. And early observational research on the benefits of vitamin D uncovered associations between higher levels of vitamin D intake and a range of health benefits.

But the studies could only tell about correlations between vitamin D exposure and disease outcomes, not whether one caused the other. Still, they were enough to fuel media hype. Dr. Oz called the supplement “the No. 1 thing you need more of.” And the vitamin D industry helped create a craze by paying prominent doctors to expound on the benefits of testing and supplementation for everyone.

But more recent randomized trials — that introduce vitamin D to one group and compare that group with a control group — have shown little or unclear benefit for both vitamin D testing and supplementation in the general population. And reviews that take these trials together to come to more fully supported conclusions, like the Lancet paper, are similarly lackluster.

In 2010, the Institute of Medicine (now known as the National Academy of Medicine) brought together an expert committee to review the evidence on the vitamin and figure out whether there was a widespread deficiency problem in North America. According to the 14-member panel, 97.5 percent of the population got an adequate amount of vitamin D from diet and the sun. (Vitamin D occurs naturally in fatty fish such as salmon and tuna, beef liver, cheese, and egg yolks. It’s also found in fortified foods such as milk, orange juice, and cereal.)

“You are at risk of D deficiency only if you have no sun exposure, live above 55 degrees latitude, and do not eat vitamin D-fortified foods or fluids [like milk],” said Chris Gallagher, a professor of Medicine at Creighton University, who wrote a comment about the Lancet paper. “About 80 to 90 percent of vitamin D comes from sunlight, and even 15 minutes in the midday will boost vitamin D levels to a good level.”

Still, testing and supplementation have exploded in the US. Over the last decade, the numbers of people using vitamin D supplements increased by a factor of four. Between 2000 and 2010, the amount Medicare spent on vitamin D testing rose 83-fold, making the test Medicare’s fifth-most popular after cholesterol.

These tests uncovered lots of low vitamin D levels — but there’s a scientific debate about how many of them are true deficiencies. Professional medical groups can’t agree on a cutoff. The Institute of Medicine recommended a diagnosis be made only for people who have less than 20 nanograms of the vitamin per milliliter of blood, but labs and other professional groups use higher thresholds. All that screening led to an explosion in diagnoses, and millions of Americans now pop daily vitamin D pills.

When I asked Avenell what she thinks about the fact that so many people are diagnosed with deficiencies, she said, “It can’t be the case that just about the entire population is deficient in Vitamin D.”

11 Exercises to Fix Rounded Shoulders and Sculpt Beautiful Posture

Published

on

By

Modern life takes its toll on our posture when we spend hours sitting and neglect the position of our spine. Poor posture leads to an imbalance in our muscles which means that they can’t support the body properly. Luckily, this can be fixed by doing a set of effective exercises. Moreover, they can help you to reduce back pain, stop headaches, increase energy, and improve circulation and digestion.

Bright Side is ready to help our readers achieve a beautiful and healthy body, and found 11 simple exercises that can be done at home by anyone. At the end we included a small tip, as a bonus for those who enjoy massage.

1. Upper trapezius stretch

It’s better to start from your shoulders first to relax your upper muscles. An upper trapezius stretch is just perfect for this.

Initial position: For this exercise, you can stand or sit on your yoga mat, whatever you like. Keep your head straight.

What to do:

  • Slowly move your right ear toward your right shoulder. When you do this, it’s normal that your left shoulder might lift as well. If it does, bring your head back to the initial position and try to relax your left shoulder.
  • Put your right hand over your head and place it on your left cheekbone. Don’t push your head down with it, it should just lie there. This will stretch your upper trapezius muscles very gently.
  • Calmly breathe and sit in this position for 30 seconds.
  • Slowly remove your hand, come back to the initial position and repeat the same on the other side.

2. Superman

The Superman exercise engages your upper and lower back. It helps you fight lower back pain and prevents a curved spine.

Initial position: Lie face down on your stomach, on your yoga mat.

What to do:

  • Extend your arms and legs. Keep your neck neutral.
  • Keep your torso stationary and lift your arms and legs up toward the ceiling. Try forming a “U” shape with your body.
  • Hold the position for 5 seconds, lower your arms and legs, and go back to the initial position.
  • Repeat 10 times.

3. Bridge

The bridge works out glutes and strengthens the lower back, which is important for good posture.

4. Reverse shoulder stretch

This is an effective exercise to stretch your back and shoulder muscles and remove tension and pain in them.

Initial position: Stand on a yoga mat, with your feet wider than your shoulders, place your straightened hands behind you, and lock your palms together.

What to do:

  • Bring your shoulder blades together and start putting your arms up. Try to feel the tension in your spine and shoulder muscles.
  • For more spine stretch bend forward and bring your locked hands up. Hold this position for 10-15 seconds.
  • Slowly return back to the initial position.
  • Repeat 20 times.

5. Foam roller exercise for upper back

A foam roller will help you to relieve pain in your back muscles, fix rounded shoulders, and improve your overall posture.

What to do:

  • Bring your hands behind your head, this will support it. Bring your hips into a bridge pose, and hold your balance, supporting your body with your legs.
  • Inhale, push your body from your heels, and roll on your spine. Stop when the roller reaches the top of your shoulder blades.
  • Exhale and roll back until the roller reaches the bottom if your rib cage.
  • Repeat this for 30-45 seconds.

6. Cat-cow exercise

The cat-cow exercise is perfect for stretching your back, lower spine, and core muscles.

Initial position: Stand on all fours on the yoga mat, place your hands right under your shoulders, and knees and feet hip-width apart. Keep your toes pointing toward your body. Your spine should be natural and straight, no bending or arching.

What to do:

  • Cat position: exhale and engage your abdominal muscles. Arch your spine up toward the ceiling, bringing your head to your chest, aligned with your spine. Hold this for 10 seconds.
  • Cow position: slowly start bringing your stomach toward the floor and try to feel the tension in your lower back. Bring your shoulder blades together. Hold this for 10 seconds and go back to the initial position.
  • Repeat 15 times.

7. Kneeling hip-flexor stretch

The kneeling hip flexor stretch will help to remove tension from your pelvic and lower back muscles.

Initial position: Kneel on a yoga mat, bring your right leg in front of you, and bend it at a 90 degree angle. Your foot is flat on the ground. Support yourself by standing on your left knee that is also bent at 90 degrees.

What to do:

  • Slowly start bringing your right knee forward and brace your core. Engage your glutes and keep bringing your hips forward.
  • Your left knee is already bent at more than 90 degrees. Keep your spine straight, don’t bend it forward or backward.
  • Hold this position for 10 seconds to feel the stretch in the muscles then slowly return to the initial position.
  • Repeat 10 times for both sides.

8. Bird dog exercise

Bird dog helps to remove back pain, strengthens the core, and promotes proper posture.

Initial position: Stand on all fours on the yoga mat, your hands under your shoulders and your knees under your hips. Your spine should be straight and neutral.

  • Return to the starting position and then repeat the same exercise with your left hand and right leg.
  • Repeat 10-15 times.

9. Forearm plank

Plank is not only effective at burning fat, but it also helps to strengthen the spine muscles, it prevents back pain, and it helps to improve your posture.

Initial position: Place your forearms on the yoga mat and align your elbows below your shoulders. Your arms should be parallel to your body at about shoulder-width distance.

What to do:

  • You can clasp your hands together for more comfort. Correct your neck and spine by looking at one spot on the floor somewhere about 30 centimeters in front of your hands.
  • Pay attention, so that your head is in line with your back.
  • Hold this position for 20 seconds.

10. T-Spine windmill stretch

The t-spine windmill stretch can help you fight pain and tension in your lower back and trunk. Moreover, it works out your shoulder muscles.

Initial position: Lie on your side on a yoga mat and bend your knees and hips at 90 degrees. Extend and stack your arms together on your right side.

What to do:

  • Raise your left arm up and then place it out to the left, opening your body up. Right now, your shoulder blades should be on the floor and your legs should remain in the same position.
  • Hold it for a couple of seconds and return to your initial position.
  • Do 30 repetitions on each side.

11. Tight shoulder massage

A simple tennis ball can help you to remove pain in your shoulders in different areas and relax them. All you need here is a tennis ball and a wall.

Initial position: Stand next to the wall and face it. Place a tennis ball on the wall and lean on it. Your chest should push the ball inside your shoulder.

What to do:

  • Start making a circular movement around this muscle and try to find a trigger point.
  • Hold a ball on this point until you feel that the tension and pain are gone.
  • Keep doing this until you relax all of your trigger points.
  • Repeat on the other shoulder.

Bonus: Thai massage is amazing for your back and shoulders.

Thai massage is an ancient form of massage that uses stretching and gentle pressure on the body to relieve muscle and joint pain, and balance your body. This massage helps to make muscles more flexible and removes chronic stiffness. For better results in achieving a healthy back and good posture, you can try this type of massage, focusing on your spine muscles.

Exercises can be effective, but it’s also important to pay attention to your posture throughout the day and strive to keep your spine straight. Do you have good posture? Maybe, you have a couple of exercises that help you relieve back and shoulder pain? Let’s share in the comments!

Why Iran is attacking oil tankers in the Strait of Hormuz

Published

By

The Strait of Hormuz is a narrow waterway that lies between Iran and Oman. Dozens of tankers carry oil through the 21-mile-wide passage each day. This flow of oil represents 20 percent of the world’s supply.

Most of the tankers traveling through the Strait of Hormuz are bound for Asia. But an attack on any tanker there, regardless of its destination, can affect the price of oil everywhere. That’s because oil is a globally traded product — a drop in supply from the Persian Gulf can drive up prices from other sources around the world. After two tankers were attacked in June, the price of Brent Crude — oil sourced from the North Sea — jumped by nearly $2 per barrel.

The attacks in June weren’t the only incidents in Hormuz in recent months. Several other oil tankers have been seized, attacked, and harassed. These tankers — and this narrow water passage — have become a center of conflict between the US and Iran. It’s a conflict with the potential to escalate in one of the world’s most important oil chokepoints, sending the global economy into a tailspin.
