Although the apparent protective association with whole-grain and cereal fiber intakes persisted after adjustment for lifestyle and dietary factors associated with a healthier lifestyle, we cannot rule out residual confounding.

Carbohydrate and insulin response -

These results should be viewed in the context of nutrition recommendations and usual dietary intake. The average carbohydrate consumption in the U. Our study does have limitations. First, the period on each diet was only 6 weeks.

However, prior feeding studies by our group have shown that blood pressure and lipid responses occur quickly, within 2—4 weeks of a dietary change. Second, we assessed insulin sensitivity through the use of fasting indices, rather than the gold standard physiologic clamps.

In the absence of dynamic measurements, we have several measures of insulin sensitivity, and QUICKI appears the best suited for our population 8 , 14 , Third, insulin sensitivity is only a surrogate outcome; correlations with clinical outcomes such as incident type 2 diabetes or clinical complications related to insulin sensitivity were not assessed.

The strengths of our trial remain that it is a large, randomized, tightly controlled feeding study that enrolled a diverse population. Our subgroup analyses, although provocative, rely on numbers of participants that are too small to effectively draw bold conclusions, and the assessments for interaction do not meet the criteria for statistical significance.

In conclusion, our analysis suggests that a diet rich in unsaturated fats, which is commonplace in Mediterranean-style diets, improves insulin sensitivity in a population at risk for cardiovascular disease.

Given the well-recognized challenges of sustaining weight loss, our results suggest an alternative approach to improving insulin sensitivity. Clinical trial reg. NCT, clinicaltrials.

Rationale and design of the optimal macro-nutrient intake heart trial to prevent heart disease OMNI-heart. No specific dietary recommendations have been advocated by health agencies for treatment of insulin resistance or the metabolic syndrome.

A high cereal fiber content and low glycemic index are inherent attributes of most whole-grain foods. Therefore, in terms of implementing dietary change, emphases should be place on increasing dietary intakes of whole-grain foods. Given that the metabolic syndrome is an identifiable and potentially modifiable risk state for both type 2 diabetes and cardiovascular disease, increasing whole-grain cereal fiber may reduce the potential untoward effects of carbohydrate on risk of these diseases.

However, more longitudinal studies are required to ascertain which aspects of carbohydrate nutrition are linked to development of the metabolic syndrome milieu.

Characteristics of subjects in the Framingham Offspring Cohort across quintile categories of HOMA-IR insulin resistance. Data are means unless otherwise indicated.

Geometric means are given for levels of fasting insulin. P values for trend for continuous variables or Mantel-Haenzel χ 2 for categorical variables across quintiles of HOMA-IR. Multivariate adjusted geometric mean HOMA-IR and prevalence OR of metabolic syndrome across quintiles of carbohydrate-related dietary factors.

Geometric mean HOMA-IR adjusted for sex, age, BMI, waist-to-hip ratio, cigarette dose, total energy intake, alcohol intake, percentage saturated fat, percentage polyunsaturated fat, multivitamin use, physical activity, and treatment for blood pressure.

Results were essentially the same when the analysis was repeated using fasting insulin rather than the HOMA-IR. Adjusted for sex, age, cigarette dose, total energy intake, alcohol intake, percentage saturated fat, percentage polyunsaturated fat, multivitamin use, and physical activity.

Quintile categories are based on energy-adjusted values using the residual method, with the exception of whole and refined grains. IRS, insulin resistance syndrome. This material is based upon work supported in part with federal funds from the U.

CVD Prevention. Arch Intern Med. Diabetes Care. Louis Aronne's study in Diabetes Care found that insulin and glucose levels were significantly lower when protein and vegetables were eaten before carbohydrates. Eating protein and vegetables before carbohydrates leads to lower post-meal glucose and insulin levels in obese patients with type 2 diabetes, Weill Cornell Medical College researchers found in a new study.

This finding, published June 23 in the journal Diabetes Care, might impact the way clinicians advise diabetic patients and other high-risk individuals to eat, focusing not only on how much, but also on when carbohydrates are consumed. Louis Aronne , the Sanford I.

Aronne, who is also director of the Comprehensive Weight Control Center at Weill Cornell. Patients with type 2 diabetes typically use a finger prick test to check their glucose levels throughout the day. Maintaining normal levels, specifically after meals, is of the utmost importance, because if a diabetics' blood sugar level is consistently high or frequently spikes, they risk complications of their disease, including hardening of the arteries and eventually death from heart disease.

This study looked to validate and advance previous research that showed eating vegetables or protein before carbohydrates leads to lower post-meal glucose levels.
