There is good trial evidence that eating foods rich in fibre such as vegetables, can help lower weight, and improve levels of risk factors known to cause heart disease. The present observational study can not overcome such evidence and its conclusions can be debated since the authors may have over adjusted for factors that account for lower intake of vegetables, the results are not surprising. Picking out one single component and assuming just adding it to the diet, e.g., vegetables, is not likely to result in the desired effect.
