Tubuh manusia memerlukan 46 jenis nutrient setiap hari untuk berfungsi secara optimum. Nutrien-nutrien ini dikenali sebagai nutrien metabolik. Jika sel-sel kekurangan nutrien, metabolisme sel akan tergugat dan menyebabkan penyakit kronik. Selain itu, sesuatu nutrien itu saling berkait antara satu sama dengan yang lainnya. Adalah penting untuk memastikan pengambilan semua nutrien secara seimbang setiap hari. Kekurangan mana-mana jenis nutrient akan teruk menjejaskan kesihatan kita. Menurut laporan Amerika Syarikat, 2/3 daripada semua kematian disebabkan oleh ketidakseimbangan pemakanan dan kekurangan nutrient. Kita perlu berhati-hati tentang makanan yang diambil setiap hari kerana ini menentukan tahap kesihatan kita. Walaupun tubuh kita dapat menghasilkan sesetengah nutrient penting seperti Vitamin D, atau mungkin diet biasa kita dapat menyumbangkan keperluan asas kesihatan tertentu, kita tidak boleh bergantung pada mana-mana sumber diatas untuk memperoleh nutrient secukupnya untuk tubuh kita. Oleh itu, ilmu tentang kepentingan nutrient dan sumber-sumbernya dapat membantu kita menguruskan kesihatan kita dengan lebih baik.
Makanan ini terdiri dari tiga kumpulan iaitu makanan yang memberi tenaga, menjauhi dari penyakit dan membina sel-sel dan tisu tubuh.

How to Get Six Pack Abs
Strengthen your abdominal muscles and lose body fat. The concept is simple, but putting it into action isn't simple at all. It will take dedication, time and patience to get a six pack but in the end, the effort is well worth it. To get six pack abs you need to do two things: Build muscle and lose fat and you get this by dieting and exercising daily. You can have the most toned and muscular abs but it will not show if there is a layer of fat over them. This article will discuss ways in which you can accomplish both of these goals.
Steps
1. Do Crunches. Lie on the floor (with or without a mat) with your arms in front of your chest (never behind your head). Bend your knees. Raise your shoulders (upper torso) towards your knees, using strictly your abdominal muscles. It is very important to not lift your entire back off the floor, as this can cause back strain, and the extended movement does not help you develop six pack abs any faster. The most important part of the crunch is the initial flexing of your abs as you lift your shoulders off the floor. As soon as you begin lifting off the floor exhale through your mouth, ending with a gasp once your shoulders are off the floor. Then pause for a second once you are at the top of the crunch and exhale the last bit of air from your diaphragm while flexing your abs. Now lower back down slowly and controlled while inhaling through your nose, just until your shoulder blades touch the ground. Do not let your head touch the ground.
2. Do Sit Ups. Lie on the floor, feet on the floor, knees up and hands crossed on your chest. Have someone hold your feet down, or wedge them underneath something heavy. Sit all the way up, lifting your lower back off the floor along with your shoulder blades. Lower yourself down. Repeat. Once this becomes relatively easy for you (i.e. you can do a quite a bit with ease) start adding more challenges. Find an incline bench or do these with an exercise ball. Once you "graduate" from that, do weighted sit ups. Hold a weight on your chest while you do these. As these become easier, hold heavier and heavier weights.

Once you "graduate" from that, do weighted sit ups. Hold a weight on your chest while you do these. As these become easier, hold heavier and heavier weights.
4. Train your entire core. To build really great abs it's important to first understand what abs do. Their full name is 'rectus abdominis'. The 'rectus' bit, is Latin for 'straight, proper, upright'. Contrary to popular opinion, the abs' primary job is not to curl you up into a ball, but they work together with the back muscles to maintain correct posture and stabilize the spine. Therefore training your abs without training your back will create an imbalance in the musculature that supports your spine. These muscles are not just for show! So the best exercises for abs are ones that force your entire core to go into overdrive to support your spine. Some exercises that do this are squats and deadlifts. These exercises will train your entire core to work together to do what it is designed to do. At the same time they will also train a lot of other muscles (e.g. glutes and quads), and this promotes even more rapid fat loss as the body recovers.
5. Do Leg Lifts. Lie on the floor, legs straight out, hands at your sides. Lift your legs straight up (not bending your knees at all) until they're at a 90 degree angle (or close). Lower your legs and repeat without letting your legs touch the floor. For more challenge there is equipment at most gyms that will allow you to raise yourself up using your arms as support and dangle your legs. If you're using this piece of equipment, you can make it easier by just raising your knees to your chest. It's more difficult to raise your legs to a horizontal position with your legs straight. This helps firm up the lower abdomen. If you're truly a monster, try doing leg lifts with a medicine ball hanging from your feet. Or, hang from a pull up bar and raise your legs in front of you all the way up to the bar.

Healthy Habits to Improve Your Life
By Dulce Zamora
Healthy Habit No. 1: Eat Breakfast Every Morning
Breakfast eaters are champions of good health. Research shows people who have a morning meal tend to take in more vitamins and minerals, and less fat and cholesterol. The result is often a leaner body, lower cholesterol count, and less chance of overeating.
"That one act [of eating breakfast] seems to make a difference in people's overall weight," says Melinda Johnson, RD, a spokeswoman for the American Dietetic Association (ADA). She says breakfast can hold off hunger pangs until lunchtime and make high-calorie vending machine options less enticing.
Not only that, researchers at the 2003 American Heart Association conference reported that breakfast eaters are significantly less likely to be obese and get diabetes compared with nonbreakfast eaters.
Another study in the International Journal of Food Science and Nutrition showed that people who consumed breakfast cereal every day reported feeling better both physically and mentally than those who rarely ate cereal in the morning.
For kids, breakfast appears to enhance alertness, attention, and performance on standardized achievement tests, reports the ADA.
To get the full benefits of breakfast, the Mayo Clinic recommends a meal with carbohydrates, protein, and a small amount of fat. They say that because no single food gives you all of the nutrients you need, eating a variety of foods is essential to good health.
Yet, even with so much scientific support that breakfast does the body good; many people still make excuses not to eat in the morning. They include not having enough time and not feeling hungry. For these people, Johnson suggests tailoring breakfast to the day.
"When I'm getting ready in the morning, I don't really want to take the time to eat breakfast because that would mean sacrificing sleep," says Johnson. "So I bring my breakfast with me, and I know I have an hour when I'm reading emails in the office when I can eat it. By that time, I'm hungry because I've been up for almost a couple of hours."
