Fiber from whole grains
Among fiber sources besides vegetables, whole grains are the most accessible and diverse group. Whole grains such as barley, whole wheat, brown rice, buckwheat, oats, and quinoa all contain significantly higher amounts of fiber than refined grains. These are sources of both soluble and insoluble fiber, which have the effect of supporting cholesterol reduction and stabilizing blood sugar.
For example, oats and barley contain beta-glucan, a form of soluble fiber that can slow down sugar absorption and lower bad cholesterol levels. Meanwhile, other whole grains are high in unsaturated fiber, which helps stimulate the gut to function more effectively.
Fiber from beans and legumes
Beans, lentils, chicken beans and soybeans are not only rich in plant-based protein but also one of the richest sources of fiber. A cup of cooked black beans provides much higher amounts of fiber than the same amount of white rice or potatoes. This type of food is also very versatile when processed such as salads, soups to traditional dishes such as curry or chili.
In addition, these legumes also contain many vitamins and minerals such as iron, folate and potassium, which contribute to maintaining energy and enhancing cardiovascular health.
Fiber from fruits
In addition to vegetables, fresh fruits are also a great source of fiber. Apples, pears, berries (such as strawberries, raspberries, blueberries) and avocados all contain high levels of fiber, especially when eaten with the skin. Fruit peels often contain mostly unsaturated fiber, which helps increase stool volume and promote digestion.
In addition, fruits also provide many antioxidants, vitamins and minerals - important factors in protecting cells from damage and supporting the immune system.
Nuts
Chia seeds, flax seeds, pumpkin seeds and other nuts not only contain healthy fats but are also a rich source of fiber. Chia seeds and flax seeds, when soaked in water, have the ability to create gel because soluble fiber helps prolong the feeling of fullness and supports digestion.
In addition, these nuts are also rich in omega-3, vitamin E and minerals such as magnesium and zinc, bringing comprehensive health benefits.
Although green vegetables are very important, to meet daily fiber needs - an average of about 25-38g/day depending on gender and age, you should combine many different food groups. Focusing on sources of fiber rich besides vegetables will make meals more diverse, delicious and scientific.
