Eating Nuts May Help Cholesterol Levels


By Ed Edelson
HealthDay Reporter

MONDAY, May 10 (HealthDay News) — An analysis of studies has produced what its authors describe as a precise description of the beneficial effects of nut consumption on cholesterol and other heart-related fats.

It provides “the best evidence yet that eating nuts reduces LDL cholesterol and improves the blood lipids profile,” said Dr. Joan Sabate, who chairs the nutrition department at the Loma Linda University School of Public Health in California and was a co-author of the report, published May 10 in Archives of Internal Medicine.

Sabate and fellow researchers at the university pooled data on 583 men and women who had participated in 25 nut consumption trials. The results showed that eating about 2.3 ounces of nuts a day — a third of a cupful — reduced total cholesterol levels by 5.1 percent and “bad” LDL cholesterol by 7.4 percent.

That amount of nut eating also improved the ratio of LDL cholesterol to “good” HDL cholesterol by 8.3 percent and caused a decrease of 10.2 percent in triglyceride levels among people with high levels of those blood fats.

Sabate is a leading figure in the somewhat limited field of nut nutrition. His first report on the beneficial effects, published in 1993, led to other studies that eventually prompted the U.S. Food and Drug Administration to issue a qualified health claim for nuts a decade later.

The 2003 FDA statement said that “scientific evidence suggests but does not prove that eating 1.5 ounces of most nuts per day, as part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease.”

On food labels, that claim is followed by a caution: “See nutrition information for fat content.”

The FDA statement was issued in response to a petition filed by the International Tree Nut Council Research and Education Foundation, which supports the work done by Sabate and other nut nutrition researchers. The foundation helped fund the latest report.

The new study found that the benefits from eating nuts was greatest among thin people, those with high LDL cholesterol and those consuming a fat-rich diet.

But enthusiasm for nuts should be restrained, Sabate said. They are highly caloric, and thus can contribute to obesity. A 3-ounce-a-day limit was recommended.

Jeannie Gazzaniga-Moloo, a spokeswoman for the American Dietetic Association who is in private practice in Sacramento, Calif., said that “nuts can be a very healthy addition to any diet,” but she recommends eating somewhat less of them.

She said she suggests that her clients consume about an ounce a day of nuts — about 22 walnuts, for example, providing about 150 calories — as part of their daily diet. “They are rich in protein and dietary fiber as well as numerous proteins and in various vitamins,” Gazzaniga-Moloo said.

“They should eat the nuts they enjoy,” she said. “They can try a variety.”

Sabata said that the type of nuts eaten doesn’t seem to matter. The study found essentially the same results for walnuts, almonds, peanuts, pecans, hazelnuts, macadamias and pistachios.

“Nuts are a matrix of healthy nutrients, and the most obvious reason for the cholesterol-lowering effect is their unsaturated fat content,” Sabate said. “Nuts also contain fiber, vegetable protein, phytoesterols and other antioxidants.”

The best evidence for the beneficial effect of nuts, though, has come from studies of walnuts and almonds, he added.

Berapa Banyak Air Yang Perlu Diminum?

Ada orang kata jangan minum air banyak-banyak. Minum seteguk dua saja, ini petua untuk awet muda. Ada pendapat yang mengatakan kita perlu meminum 8 gelas sehari. Yang mana betul?

Pendapat yang pertama, memang tidak betul. Yang kedua? Tidak berapa betul! “8 gelas sehari” lebih merupakan sebagai lagenda yang telah diterima sebagai fakta.

Baru-baru ini, Jurnal Psikologi Amerika mendedahkan bahawa tidak terdapat bukti saintifik yang dapat menyokong teori “8 gelas sehari”. Jangan salah faham pula. Saintis tersebut bukan mengatakan kita tidak memerlukan air. Tetapi nasihat agar kita mengambil 8 gelas air sehari bukanlah satu nasihat yang baik.

Pertama, kita perlu meminum air berulangkali di sepanjang hari. Meminum 8 gelas di waktu pagi dan mempercayai bahawa anda sudah meminum air yang cukup untuk hari tersebut adalah berbahaya.

Mereka yang meminum air, walau setengah gelas, pada setiap jam akan mendapati diri mereka begitu bertenaga.

Berapa banyak yang perlu diminum? Ianya bergantung kepada cuaca dan aktiviti yang anda jalankan. Lebih banyak anda kehilangan air, lebih banyak yang perlu diminum, lebih banyak dari 8 gelas. Tetapi jangan pula meminum terlalu banyak. Kenapa pula? Meminum terlalu banyak air boleh menyebabkan keracunan air (sekiranya menahan membuang air kecil) ataupun situasi elektrolit tak seimbang.

Peringatan: Lebih banyak anda meminum air, lebih banyak anda perlu menggantikan elektrolit anda. Di mana anda boleh memperolehi bekalan
elektrolit? Dari air minuman sukan seperti 100 Plus, Excel dll.
