Final determination regarding regarding partially hydrogenated oils removing trans fat. For health benefits the active bioavailable dose appears to be an important parameter to consider rather than the dose ingested. It is essential to have a deep understanding of the physicochemical properties of these compounds so that their behaviour in the gastrointestinal tract during digestion can be predicted.
As discussed in section 3, the degree of complexity of the food matrix and its structural organisation can have an impact on health by acting on two levels, the macro- and micro-scales. On the macroscale, the structure of the food will affect how nutrients and bioactives are released, thereby influencing the rate and extent of their digestibility. Firstly, a reduced rate of nutrient digestion is likely to have health benefits related to gastric emptying, satiety, glucose and lipid metabolism.
This is because over-processed foods are often highly digestible, causing an overload of physiological cues elicited by a rapid and large release of nutrients. Secondly, the reduced rate of digestion will also permit a sustained release of bioactives as observed with antioxidants.
The capacity of oats to sequester bile acids has been found to be higher, presumably resulting in greater bile acid excretion for complex sources of the polymer i. Because phytosterols have limited solubility both in water and lipid, their bioavailability and efficacy rely on many factors, such as the quantity of lipid, the type of phytosterol i.
The mixture of free i. Polyphenols when associated with dietary fibres have been shown to reduce cholesterol levels. It seems reasonable to venture the hypothesis that the proportion of compounds present in oat, and the complex associations between them, influence the bioavailability and activity of the bioactives.
A thorough analysis of the literature on the cholesterol-lowering effect of oat, together with current knowledge of the food structure, suggests that the concerted action of the oat constituents, delivered in an optimal amount in relation to each other, could enhance the functionality of oat and elicit a positive, or balanced, physiological response.
One of the main challenges faced today by the industry is to find the right balance between none or little food processing and high levels of food transformation. As discussed above, oat requires to be processed to make it safe to consume but not to such an extent that it loses its nutritional values and processing become detrimental. A distinction ought to be made between oat-based foods according to their degree of processing, which will help identify the foods with optimal health benefits.
In order to avoid fluctuations between batches and to ensure a high quality of the products, detailed characterisation is fundamental to define the ranges of bioactivity. These foods also have to be attractive to consumers if the health impacts are to be fully realised, which is another challenge to the food industry. Further research should therefore aim at identifying the most active forms of oat and the combination of nutrients and phytochemicals in relation to cholesterol levels and risk of cardiovascular disease.
A better characterisation of the structural form of oat that is ingested and as it progresses through the gastrointestinal tract is still required to provide valuable information for the design of healthier food products.

Abstract Epidemiological and interventional studies have clearly demonstrated the beneficial impact of consuming oat and oat-based products on serum cholesterol and other markers of cardiovascular disease. Introduction It is widely recognized that the intake of dietary fibre in a typical Western diet is below recommendations.
The oat matrix and its impact on cholesterol and risk of cardiovascular disease 2. Oat structure and composition A food matrix can be described as the structure and hierarchical organisation from molecule to tissue of the components of a food product. Open in a separate window. Structural representation of the oat grain presenting different oat tissues i.
Oats and their cholesterol-lowering effect In this review, we chose to investigate the effect of oat and oat-based products on lipemia cholesterol and triglycerides and other cardiovascular risk factors based on the differences in food matrices in order to correlate differential effects according to the physicochemical characteristics of these matrices. Table 1 A summary of some of the human studies on the effect of oat-based products on lipemia.
Oat bran Oat bran as such has been tested in animal models and in humans. Oat flakes Different diets e. Degree of processing and functionality 3. Effect of processing on oat grain structure and constituents Despite being necessary for food safety, conservation, convenience, palatability and digestibility, processing can generate foods whose regular consumption has been associated with the development of chronic lifestyle related diseases i.
Effect of processing on oat functionality As we had previously underlined, processing can influence the oat matrix qualitative effect and its composition quantitative effect.
Synergistic action of oat constituents In their article published in , Jacobs and co-workers clearly presented the concept of food synergy 24 and later, in , Fardet and co-workers showed the necessity for nutrition research to move towards a holistic, integrative approach. Oat cholesterol-reducing agents Oat groat is rich in a wide range of bioactive compounds, some of them present in small quantities.
A can of 4 bean mix can be thrown into salads and stir-fries for a quick and easy cholesterol lowering boost. An important part of a healthy Mediterranean diet, the mono unsaturated fats in extra virgin olive oil may help to lower LDL cholesterol when used to replace saturated fats found in meat and butter.
Top tip: Make your own salad dressings using extra virgin olive plus lemon juice or apple cider vinegar. Drizzle olive oil over steamed or baked vegetables. Replace butter and other oils in recipes with extra virgin olive oil. For a quick heart-healthy breakfast why not try multigrain toast spread with avocado and served with baked beans?
Apples and pears are rich in pectin, a soluble fibre which is also found in strawberries, oats and beans. Pectin helps to reduce cholesterol absorption and may help to lower LDL cholesterol.
One apple contains approximately one gram of soluble fibre and a large pear contains roughly three grams. Top tip: Choose an apple or pear as a naturally sweet treat to satisfy afternoon cravings. Chop up an apple and serve it with nuts and yoghurt as a heart-friendly snack or healthy breakfast.
Add them sliced to your favourite salad recipe. Look for ways to add these cholesterol-lowering foods to your weekly and daily diet. As part of a healthy diet and lifestyle, these foods may help to reduce your cholesterol and lower your risk for heart disease. A morning bowl of oatmeal can give you benefits towards heart health, including lowering your cholesterol. Oatmeal is made of ground oats that can be made into a variety of foods, including porridges, cookies, and snacks.
Studies also have shown that oatmeal has some heart-healthy benefits. This is mainly due to the rich source of water-soluble dietary fibers , particularly beta-glucan, that are found in oatmeal. Over the years, there have been many research studies that have proven the benefits of oatmeal in lowering cholesterol levels. The U. Food and Drug Administration is convinced. Oatmeal was one of the first foods to carry the heart healthy distinction on its label because of promising research findings.
It is thought that the oat fibers in the oatmeal mix with cholesterol in the small intestine, then bind to the cholesterol molecules and carry it out of the body instead of it being absorbed into the blood.
According to the studies in adults, LDL cholesterol may be lowered by 10 percent in some cases. In these studies, anywhere between 40 and 60 grams or roughly one bowl of oatmeal was consumed by each subject per day. The cholesterol-lowering benefits of oatmeal are also dose-dependent.
That is, the more oatmeal you eat, the lower your cholesterol will go. Although oatmeal is helpful in lowering cholesterol, some of the ingredients placed in oatmeal may not be. These include butter , chocolate, whole milk, and cheese.
