Eating Egg Yolk Is Bad For Your Heart? Science Says The Opposite

Eating Egg Yolk Is Bad For Your Heart? Science Says The Opposite

Nutrition research suggests that eggs not only are a convenient source of nutrients but they can also play a pivotal role in weight management, muscle strength, healthy pregnancy, brain function, eye health, and more. In fact, according to a study done by the Egg Nutrition Center,[1] simply consuming one egg a day reduces the risk of stroke by as much 12 percent.

Egg Myth-Busting

Decades-old research has sustained and perpetuated the idea that eggs are bad and should be consumed sparingly if at all. This was largely because one large egg contains between 186 and 213 milligrams of cholesterol.[2] And all of the cholesterol is in the yolk.

Scientists and health professionals have drilled into our brains that high blood cholesterol is the primary cause of heart disease. Cholesterol- in and of itself–is not bad.[3] It helps your body build new cells, insulate nerves, produce hormones, and make testosterone, which all in-turn help to increase energy and build muscle. Under normal circumstances, the liver produces all the cholesterol the body needs. However, cholesterol also enters your body from animal-based foods like milk, eggs, and meat. Too much cholesterol in your body can increase your risk for developing heart disease.[4] Since eggs are fairly high in cholesterol, it was assumed that eating them regularly–particularly the yolks–was a precursor to heart disease.

Today, researchers understand that cholesterol in food is not the true and sole culprit for heart disease. Studies have revealed that saturated and trans fats actually have a much greater effect on blood cholesterol. According to research conducted by Dr. Luc Djoussé, a heart disease researcher at Harvard Medical School, dietary cholesterol does not translate into high levels of blood cholesterol.[5]

“Current scientific data do not justify worries about egg consumption, including egg yolk, when it comes to heart health,” he says.

Eggs–specifically the yolks–are good for your health

Egg yolks contain almost all the vitamins and minerals in the egg. There’s just no comparison. Most of the vitamins and minerals in an egg are lost if the yolk is discarded. The white of a large egg contains around 60 percent of the egg’s total protein. Additionally, fat and cholesterol in the egg yolk[6] contain fat-soluble nutrients like vitamins D, E, A, choline, and carotenoids,[7] which may aid the body in absorbing these essential and important nutritional components of eggs.

Eggs also contain phospholipids which may affect cholesterol and inflammation levels in beneficial ways, help decrease blood pressure, and improve vascular function.[8] Preliminary research results have revealed that phospholipids may also help to protect against Alzheimer’s Disease,[9] although the results from these studies are still far from definitive.

In 2000, the American Heart Association (AHA) revised its dietary guidelines and gave healthy adults the green light to enjoy eggs once again. The AHA’s guidelines now allow healthy adults to consume an egg a day but still advise on keeping the total daily cholesterol limit to less than 300 mg.

Best cooking methods to unlock eggs’ nutritional benefits

Applying heat to good food is a naturally destructive process. The chemistry of heating foods looks a lot like unwinding molecules. In vegetables, heat can break down cell walls to sometimes help make nutrients more accessible to your gut. In egg whites, the proteins become unwound, to become slightly more bio-available (which refers to the proportion of a nutrient that is absorbed from the diet and used for normal body functions). Or to put it simply, heating egg whites is generally beneficial. The yolks, however, should be prepared with as little heat as possible, because heat damages fats and the vital nutrients inside. 

Raw eggs are the most nutrient-rich way to consume eggs, however experts warn against this practice as raw eggs can contain Salmonella[10] and other harmful contaminates.

7 Amazing Things That Will Happen When You Do Plank Every Day

7 Amazing Things That Will Happen When You Do Plank Every Day

Bodyweight exercises are gaining ground in the fitness world due to the practicality and simplicity of getting in shape using your own body weight. Planks are one form of bodyweight exercises that will never go out of fashion. Planks are one of the most effective exercises you can do. Why? Because they require a small time investment on your part, and offer the chance to achieve substantial results in a relatively short span of time.

Video Summary

Why is it important to train up our core strength?

There are numerous sites and blogs which detail ways to build your core muscles or core strength. Often though, these sites neglect to explain what your core muscles actually are, and why building them is important.

This is quite surprising, as core muscles are quite easy to explain. Your core muscles are a series of muscles in your midsection, and are used in most forms of movement. Though they aren’t housed in your arms or legs, your core muscles can help transfer force from one limb to another, or are used in addition to muscles in your arms or legs to increase their effectiveness. As such a strong core will make a big improvement on your ability to move and exercise further.

Also they are great for helping other muscles in your midsection such as your abdominal muscles. Your abdominal muscles are important for supporting your back and spinal column, and as such are important aids in preventing injuries. However for them to be most effective you need to spend a lot of time developing your core muscles.

In short, planking exercises can make a huge improvement in your muscles down your whole body. Making them a hugely effective exercise to perform.

One Exercise, multiple benefits

There are few forms of exercise as effective at building your core as planking exercises. However, planking exercises benefit far more than just your core strength.

By holding yourself in the position for a planking exercise, you’ll notice that your biceps, neck, and shoulder muscles are also being tested and strained. This this encouraging their buildup and development. This is great news if you like to do press ups, developed shoulder muscles will have a big impact on your press up performance.

When planking, you are holding yourself up through your arms and biceps and so by holding a planking position, your arm muscles are being toned and developed. Making planking a great alternative exercise to other forms of bicep developing exercises.

Moving down your midsection, successful plank exercises actually develop the muscles in your butt! These muscles tend to be ignored by a lot of exercises, so this is another great benefit of plank exercises.

In much the same way as you develop your biceps and arm muscles, holding the planking position helps develop the muscles in your thighs too.

What is even better is that planking exercises don’t take much time at all. In fact you should probably only spend about ten minutes max per day in the planking exercise.

What will happen when you start doing planks every day

    1. You’ll improve core definition and performance: 

    Planks are an ideal exercise for the abdominal muscles exactly because they engage all major core muscle groups including the transverse abdominus, the rectus abdominusthe external oblique muscle, and the glutes. The importance of strengthening each muscle group cannot be underestimated either, for all of these groups serve their own purpose. If you strengthen these muscle groups you will notice:

    • Transverse abdominis: increased ability to lift heavier weights.
    • Rectus adbominis: improved sports performance, particularly with jumping. This muscle group is also responsible for giving you the renowned six pack look.
    • Oblique muscles: improved capacity for stable side-bending and waist-twisting
    • Glutes: a supported back and a strong, shapely booty.

    2. You’ll decrease your risk of injury in the back and spinal column

      Doing planks is a type of exercise that allow you to build muscle while also making sure that you are not putting too much pressure on your spine or hips. According to the American Council on Exercise, doing planks regularly not only significantly reduces back pain but it also strengthens your muscles and ensures a strong support for your entire back, especially in the areas around your upper back.

      Check out this article if you would like to find out about how doing planks on different surfaces can impact the effectiveness of this exercise in strengthening your core.

      3. You’ll experience an increased boost to your overall metabolism

        Planking is an excellent way of challenging your entire body because doing them every day will burn more calories than other traditional abdominal exercises, such as crunches or sit-ups. The muscles you strengthen by doing this exercise on a day-to-day basis will ensure that you burn more energy even when sedentary. This is especially important if you are spending the majority of your day sitting in front of a computer. Also, making it a daily 10- to 1 minute home exercise before or after work will not only provide an enhanced metabolic rate but it will also ensure that that metabolic rate remains high all day long, (yes, even while you are asleep).

        4. You’ll significantly improve your posture

          Planking exercises have a great impact and improvement on your posture. This is great news as a strong posture brings with it a huge number of fantastic benefits .

          A good posture keeps your bones and joins in the correct alignment which means both your bones and joints will be better maintained and more healthy, but also means the overall effectiveness of your muscles will be improved.

          A good posture will ensure your back or spine is in the correct position and so you will suffer less back pain.

          On top of everything, someone with good posture looks better, healthier, and more confident.

          5. You’ll improve overall balance

            Have you ever felt that when you tried standing on one leg, you couldn’t stand up straight for more than a couple of seconds? It’s not because you were drunk- unless you happened to be at the time!-  but rather, it’s because your abdominal muscles weren’t strong enough to give you the balance you needed. Through improving your balance by doing side planks and planks with extensions you will boost your performance in every kind of sporting activity.

            6. You’ll become more flexible than ever before

              Flexibility is a key benefit of doing planks regularly, for this form of exercise expands and stretches all your posterior muscle groups – shouldersshoulder blades, and collarbone – while also stretching your hamstrings, arches of your feet, and toes. With a side plank added in to the mix, you can also work on your oblique muscles. This will provide you with further benefits when it comes to hyper-extending your toes, a movement that is crucial for supporting your body’s weight.

              7. You’ll witness mental benefits

              Advertising

                Plank exercises have a particular effect on our nerves, making them an excellent means of improving overall mood. How? Well, they stretch out muscle groups that contribute to stress and tension in the body. Just think about it: you are sitting in your chair, at home or at work, all day long; your thigh muscles get tight, your legs get heavy due to being bent for several hours; and tension develops in your shoulders due to being forced to slump forward all day. These are all circumstances that put too stress on the muscles and nerves. The good news is that planks not only calm your brain, but they can also treat anxiety and symptoms of depression– but only if you make it part of your daily routine.

                How to hold a plank position

                1. Get into pushup position on the floor.
                2. Now bend your elbows 90 degrees and rest your weight on your forearms.
                3. Keep your torso straight and rigid and your body in a straight line from ears to toes with no sagging or bending.
                4. Your head is relaxed and you should be looking at the floor.
                5. Hold the position for as long as you can.
                6. Remember to breathe. Inhale and exhale slowly and steadily.
                7. When your form begins to suffer, pull the plug. You’re only benefiting from the plank by actually doing the plank.

                Watch the video if you have any doubt!

                Here is a great infographic that shows the best plank variation exercises to evenly target all abdominal muscle groups:

                  How to improve your plank time gradually

                  1. Start with the easier variation if needed. You can start with a bent-knee plank if you can’t perform a regular plank yet. If you can hold a plank for more than two minutes with ease, you can move on to these tougher variations.
                  2. Practise every day. Space your planking exercise throughout the day and do 3-4 times every day. Try to hold the position 10 seconds longer each time.
                  3. Perform other body-weight exercises at the same time. Push-up and squat will improve your core strength too.

                  Are you ready to devote 5-10 minutes of your day, every day, to stay fit, healthy and, most importantly, strong as a bull? Then jump in and make doing plank exercises a part of your life.

                  Who Should Be Cautious Doing The Plank?

                  You need to be cautious doing Planking exercises if any of these risks apply to you:

                  • Prolapse
                  • After prolapse surgery
                  • Pelvic pain conditions
                  • Weak or poorly functioning pelvic floor muscles
                  • Previous childbirth
                  • Overweight

                  Choose an alternative pelvic floor abdominal exercise or consult your doctor before performing plank regularly.
