Higher intake of linoleic acid (a polyunsaturated fat) is associated with a lower risk of type 2 diabetes, specifically in men under 65 years of age and those with a BMI less than 25 kg/m2.
If you are a man under 65 and have a healthy weight (BMI <25), increasing your intake of linoleic acid (found in vegetable oils like sunflower, safflower, and corn oil) may help lower your risk of type 2 diabetes. This benefit was not seen in older or overweight men, so age and weight matter when considering this dietary change.
Linoleic acid was associated with a lower risk of type 2 diabetes in men <65 years of age (RR 0.74, CI 0.60 – 0.92, P for trend < 0.01) and in men with a BMI <25 kg/m2 (0.53, 0.33– 0.85, P for trend < 0.006) but not in older and obese men.
Why this rating
Large prospective cohort with stratified analysis showing significant interaction terms for age and BMI.

- Frequent consumption of processed meat (≥5 servings/week) is associated with a significantly higher risk of developing type 2 diabetes compared to low consumption (<1 serving/month), independent of BMI and other lifestyle factors.Good
- Higher intake of total and saturated fat is associated with an increased risk of type 2 diabetes, but this association is not independent of Body Mass Index (BMI) and disappears after adjusting for BMI.Good

- Total daily protein intake of 1.6 g/kg/day is sufficient for maximizing resistance training-induced muscle gains, with an upper confidence interval of 2.2 g/kg/day.Strong
- Resistance exercise training combined with sufficient dietary protein intake acts synergistically to maximize skeletal muscle hypertrophy, with protein intake saturating around 1.6 g/kg/day for general populations and potentially requiring 2.0-2.2 g/kg/day for resistance-trained individuals.Strong
- Trans fats should be completely eliminated from the diet, as they increase LDL cholesterol, decrease HDL cholesterol, and are directly associated with increased coronary risk.Strong
