นักวิจัยโรงพยาบาลเซนต์ ไมเคิล นครโตรอนโตของคานาดากล่าวแจ้งว่า เมื่อเทียบกับการกินข้าวกล้อง การกินถั่วแขกชนิดเม็ดแดงและเหลืองทุกวัน จะทำให้การวัดระดับน้ำตาลในเลือดที่สำคัญลดลงได้เล็กน้อย รวมทั้งความดันโลหิตและปริมาณไขมันในเลือดด้วย โดยวัดได้ว่า ผู้ที่กินเช่นนั้นมานาน 3 เดือน โอกาสที่จะเป็นโรคหัวใจและหลอดเลือด ที่เป็นมา 10 ปี จะลดน้อยลงจากร้อยละ 10.7 เหลืออยู่ร้อยละ 9.6
ดร.เดวิด เจนกินส์ชี้ว่า แม้ว่าปริมาณที่ลดแม้จะเล็กน้อย แต่ก็อย่าลืมว่า มันแสดงว่าเหนือกว่าการกินข้าวกล้อง.

Beans, beans, good for your heart, the more you eat, the better for your blood sugar levels (if you have type 2 diabetes)
- Chickpeas and lentils also reduce risk of heart disease
- Blood pressure is lowered by snacking on legumes

We’ve heard beans are good for your heart before.
Now a study has confirmed that they could help to save your life – if you have type 2 diabetes.
Eating more pulses including beans, chickpeas and lentils can reduce the risk of heart disease by controlling blood sugar levels, researchers at the University of Toronto discovered.
A low-glycaemic index (GI) diet that contains beans was found to improve glycaemic control and reduce coronary heart disease (CHD) in diabetes patients.
Dr David Jenkins and colleagues tested the effects of eating more foods from the legume group on 121 people with type 2 diabetes.
They found the low-GI legume diet reduced coronary heart disease risk by -0.8 per cent, largely because of a reduction in blood pressure.
Dr David Jenkins, a doctor at St Michael’s Hospital in Toronto, said: ‘Legume consumption of approximately 190g per day (a cupful) seems to contribute usefully to a low-GI diet and reduce CHD risk through a reduction in blood pressure.’
Low-GI foods have long been associated with improvement in blood sugar control in patients with type 2 diabetes and have been recommended in many national diabetes guidelines.
Dr Jenkins added: ‘These findings linking legume consumption to both improved glycemic control and reduced CHD risk are particularly important because type 2 diabetes is increasing most rapidly in the urban environments of populations in which bean intake has traditionally been high.’
The results were published on the Online First section of the Archives of Internal Medicine website.
The news comes just a week after scientists discovered that sitting down all day can double the risk of diabetes, heart disease and death.
So those with desk jobs might do well to grabs some beans on toast for breakfast in the morning.
Eating Nuts Daily Could Help Control Type 2 Diabetes and Prevent Complications, Study Suggests
ScienceDaily (July 12, 2011) — Eating nuts every day could help control Type 2 diabetes and prevent its complications, according to new research from St. Michael’s Hospital and the University of Toronto.
In the research, published online by the journal Diabetes Care, a team of researchers led by Dr. David Jenkins (University of Toronto Department of Nutritional Sciences; St. Michael’s Hospital Risk Factor Modification Centre) reports that consuming two ounces of nuts daily as a replacement for carbohydrates proved effective at glycemic and serum lipid control for people with Type 2 diabetes.
“Mixed, unsalted, raw, or dry-roasted nuts have benefits for both blood glucose control and blood lipids and may be used as part of a strategy to improve diabetes control without weight gain,” said Dr. Jenkins, who also has appointments with St. Michael’s Division of Endocrinology and Metabolism and the U of T’s Department of Medicine. He also serves as Canada Research Chair in Nutrition and Metabolism.
Jenkins and his colleagues provided three different diet supplements to subjects with Type 2 diabetes. One group was given muffins, one was provided with a mixture of nuts including raw almonds, pistachios, walnuts, pecans, hazelnuts, peanuts, cashews, and macadamias, and one group was given a mixture of muffins and nuts.
Subjects receiving the nut-only supplement reported the greatest improvement in blood glucose control using the glycosylated hemoglobin (HbA1c) test. The nut diet subjects also experienced a reduction in low-density lipoprotein cholesterol (known as LDL, or “bad cholesterol”). The subjects provided the muffin supplement or mixed muffin-and-nut supplement experienced no significant improvement in gylcemic control but those receiving the muffin-nut mixture also significantly lowered their serum LDL levels.
“Those receiving the full dose of nuts reduced their HbA1c [the long-term marker of glycemic control] by two-thirds of what the U.S. Food and Drug Administration recognizes as being clinically meaningful for therapeutic agents. Furthermore, neither in the current study nor in previous reports has nut consumption been associated with weight gain. If anything, nuts appear to be well suited as part of weight-reducing diets,” Dr. Jenkins said.
“The study indicates that nuts can provide a specific food option for people with Type 2 diabetes wishing to reduce their carbohydrate intake.”
