KOPI itu nikmat...tapi….???

Adakah di antara kalian yang merupakan pengggemar berat kopi??? Bagi kalian penggemar kopi, mungkin minuman hitam pekat ini merupakan minuman yang wajib diminum setiap harinya. Rasanya tidak lengkap dan merasa ada yang kurang kalau tidak minum kopi sekali aja dalam sehari.

Banyak dari qt yang berpikir, kalau dengan minum kopi yang penting badan bisa segar kembali dan rasa ngantuk juga hilang. Iya ga?? Tapi, qt juga harus tau, ada apa sih dibalik nikmatnya kopi itu??? Salah satu akibat yang ditimbulkan adalah serangan jantung.

Sejumlah peneliti di Belanda mengamati tingginya kadar homosistein dalam darah pecandu kopi. Apa siy homosistein tiu?? Homosistein merupakan substansi yang terbentuk dari metionin, yakni suatu asam amino esensial yang terbentuk pada saat tubuh mengeluarkan protein. Nah, kalau homosistein meningkat, risiko penyakit jantung juga jadi lebih besar.

Meski belum jelas bagaimana persisnya asam amino esensial mengganggu jantung, sudah terbukti bahwa zat tersebut acap kali menyebabkan timbulnya luka di berbagai lapisan dalam pembuluh darah arteri dan selanjutnya menjadi tempat menumpuknya asam lemak dan kalsium. Timbunan ini bisa mengakibatkan pengerasan dinding pembuluh darah arteri (arteriosklerosis).

Seorang peneliti Belanda menambahkan, dua minggu setelah setiap hari minum enam cangkir kopi, konsentrasi homosistein seseorang naik 10% dari angka normal. Begitu juga kadar kolesterol dan trigliserida. Namun, kenaikan ini tidak permanen. Bila kopi dihentikan dan keadaan tubuh sehat, kelebihan homosistein dapat secara alami normal kembali. Selain dengan mengurangi kafein, kenaikan kadar homosistein dapat pula dicegah dengan mengurangi konsumsi protein hewani yang banyak mengandung metionin.

Bila dalam sehari minum 1,360 g kopi kasar (sekitar 6-7 cangkir), diperkirakan risiko untuk terkena serangan jantung atau stroke naik 10%. Selain itu kadar vitamin B6 bisa berkurang sampai 21%.

Atas dasar itu alangkah baiknya tidak minum kopi, khususnya bagi mereka yang berisiko tinggi penyakit jantung. Kopi bisa digantikan segelas air jeruk, sayuran hijau, disertai konsumsi vitamin B6 dan B12. Jenis-jenis makanan dan minuman ini tidak mengandung seng dan kafein tapi tinggi mineral, vitamin serta asam folat. Padahal vitamin B6, B12, dan asam folat sangat berperan dalam menurunkan kadar homosistein dalam tubuh, sehingga penyakit jantung koroner pun bisa dihindari.

Minum kopi sih nikmat… tapi hati-hati yah…harus inget batasannya…

BuLiMiA....

Bulimia is an illness defined by food binges, or recurrent episodes of significant overeating, that are accompanied by a sense of loss of control. The affected person then uses various methods -- such as vomiting or laxative abuse -- to prevent weight gain.

In bulimia, eating binges may occur as often as several times daily for many months. These binges cause a sense of self-disgust, which leads to compensatory behaviors like self-induced vomiting or excessive exercise. A person with bulimia may also abuse laxatives, diuretics, or enemas in order to prevent weight gain.

Many more women than men have bulimia, and the disorder is most common in adolescent girls. The affected person is usually aware that her eating pattern is abnormal and may experience fear or guilt associated with the binge-purge episodes.

The exact cause of bulimia is unknown, but factors thought to contribute to its development are family problems, perfectionist personality, and an overemphasis on physical appearance. Bulimia may also be associated with depression.

In certain neurological or medical conditions, there can be disturbed eating behavior, but the essential psychological feature of bulimia, the extreme concern with body shape and weight, is not present. Organic causes for bulimia are being investigated. There is evidence that bulimia and other eating disorders may be related to abnormalities in levels of chemical messengers (neurotransmitters) within the brain, specifically the neurotransmitter serotonin. Other studies of people with bulimia have found alterations in metabolic rate, decreased perceptions of satiety, and abnormal neuroendocrine regulation (the process by which the nervous system interacts with production of hormones and hormone-like substances).

Malnutrition..

Malnutrition occurs when you do not get enough calories or nutrients to keep you healthy. Nutrients are protein, fat, carbohydrates, vitamins and minerals. Malnutrition may make your body weak.

Malnutrition is not the same thing as hunger, although they often go together. People who are malnourished lack the nutrients needed for proper health and development. Someone can be malnourished for a long or short period of time, and the condition may be mild or severe. People who are malnourished are more likely to get sick and, in severe cases, may even die.

People who don't get enough food often experience hunger, and hunger can lead to malnutrition over the long term. But someone can become malnourished for reasons that have nothing to do with hunger. Even people who have plenty to eat may be malnourished if they don't eat food that provides the right nutrients, vitamins, and minerals.

Indications of malnutrition depend on which nutritional deficiencies a child has, although they can include : fatigue and low energy, dizziness, poor immune function (which can hamper the body's ability to fight off infections), dry, scaly skin, swollen and bleeding gums, decaying teeth, slowed reaction times and trouble paying attention, underweight , poor growth, muscle weakness, bloated stomach, osteoporosis, or fragile bones that break easily, problems with organ function

Treatment for malnutrition depends on the cause. You will need to work closely with your caregiver during your treatment. Treatment for malnutrition may include increasing the calories and nutrients in your diet.

You may need to increase the calories and nutrients in your diet by doing one or more of the following:

• Eat large meals and snacks between meals.

• Eat small meals often throughout the day if you have trouble eating large meals.

• Eat or drink a nutrition supplement if you have trouble eating the right kinds and amounts of food.

• You may need to take vitamin or mineral supplements if your body is low in vitamins and minerals. Your caregiver may treat you with medicines if you have a health problem that is causing your malnutrition.

• If you cannot buy or prepare the right kinds of foods, talk to your caregiver. Ask for information about community programs that can help you.

You can then discuss treatment options with your caregivers. Work with them to decide what care may be used to treat you. You always have the right to refuse treatment.
