By Here are some simple ways to increase your fibre intake
Increasing fibre intake is a great way to improve overall health and reduce the risk of various diseases. While the blog post provides some valuable information, let’s dive deeper into the topic and explore additional aspects of fibre and its benefits.
We’ll also discuss more fibre-rich foods that readers may need to know and provide relevant research to support our claims.
Fibre is a carbohydrate in plant-based foods that our bodies cannot digest. Instead, it passes through the digestive system relatively intact, providing numerous health benefits.
There are two main types of fibre – soluble and insoluble
Soluble fibre dissolves in water, forming a gel-like substance in the digestive tract.
It helps regulate blood sugar levels, lowers cholesterol, and promotes a healthy gut microbiome. On the other hand, insoluble fibre adds bulk to the stool, aiding in regular bowel movements and preventing constipation.
How much fibre should you be eating?
The recommended daily fibre intake varies based on age, sex, and overall health. The current dietary guidelines provided by reputable health organisations suggest the following daily fibre intake:
The American Heart Association:
Women: 25 grams of fibre per day
Men: 38 grams of fibre per day
The European Food Safety Authority (EFSA):
Adults: 25 grams of fibre per day
These recommendations are meant to serve as general guidelines and individual fibre needs may vary based on factors such as activity level, calorie intake, and specific health conditions.
However, studies consistently show that most people need to consume more fibre.
Surveys and research conducted in various countries, including the United States, the United Kingdom, and Australia, indicate that the average fibre intake falls significantly below the recommended amounts.
For instance, a study published in the Journal of the Academy of Nutrition and Dietetics analysed data from the National Health and Nutrition Examination Survey (NHANES) in the United States and found that the average fibre intake was approximately 16 grams per day, well below the recommended levels.
Similarly, the National Diet and Nutrition Survey in the United Kingdom revealed that adults consumed an average of 19 grams of fibre per day, below the recommended intake.
Low fibre intake is a concern because it can contribute to various health issues, including constipation, elevated cholesterol levels, increased risk of heart disease, diabetes, and obesity. Therefore, it is essential to increase fibre consumption and meet the recommended daily intake consciously.
Now, let’s delve into some other high-fibre foods that readers may need to become more familiar with.
One: Artichokes
Artichokes are not only delicious but also a fantastic source of fibre. The fibre content of artichokes is primarily attributed to two components: inulin and cellulose. A medium-sized artichoke can contain around 10 grams of fibre, making it one of the highest-fibre vegetables. They also provide antioxidants and are known for their liver-supporting properties.
Inulin: Artichokes are rich in inulin, a type of soluble fibre. Inulin is a prebiotic fibre that serves as food for the beneficial bacteria in our gut. It promotes the growth of these beneficial bacteria, known as probiotics, which play a vital role in maintaining a healthy gut microbiome. A healthy gut microbiome has various health benefits, including improved digestion, enhanced immune function, and reduced inflammation.
Cellulose: Artichokes also contain cellulose, which is an insoluble fibre. Cellulose adds bulk to the stool and promotes regular bowel movements, helping prevent constipation and maintaining a healthy digestive system.
It’s worth noting that some of the health benefits of artichokes are better preserved when cooked gently or steamed rather than heavily processed or fried. So, incorporating artichokes into your diet, whether in salads, dips, or as a side dish, can contribute to a fibre-rich, nutritious, and delicious meal that supports your overall health.
Two: Brussels Sprouts
Brussels sprouts are cruciferous vegetables packed with fibre.
Half a cup of cooked Brussels sprouts can provide around 4 grams of fibre.
The soluble fibre, such as pectin, dissolves in water and forms a gel-like substance in the digestive tract. Insoluble fibre, mainly cellulose, adds bulk to the stool. Combining soluble and insoluble fibre promotes healthy digestion, prevents constipation, and supports regular bowel movements.
Additionally, they are rich in vitamins C, K, and folate and are a good source of antioxidants.
Additional nutrient advantages Brussels sprouts provide:
Antioxidant-rich: Brussels sprouts contain various antioxidants, including vitamins C and E, beta-carotene, and flavonoids.
Antioxidants help neutralise harmful free radicals in the body, reducing oxidative stress and protecting cells from damage. This antioxidant activity is linked to a lower risk of chronic diseases, including heart disease, cancer, and age-related macular degeneration.
Cancer-fighting potential: Brussels sprouts belong to the cruciferous vegetable family, known for their potential cancer-fighting properties.
They contain compounds called glucosinolates, which are broken down into biologically active compounds like sulforaphane. These compounds have been shown to have anti-cancer effects, including inhibiting the growth of cancer cells and enhancing the body’s detoxification processes.
To maximise the nutritional benefits of Brussels sprouts, it’s best to cook them lightly, such as by steaming or roasting, to retain their nutrients. Incorporating Brussels sprouts into your meals can provide a flavorful and nutritious addition to a balanced diet, supporting digestive health, offering antioxidant protection, and potentially reducing the risk of chronic diseases.
Three: Flaxseeds
Flaxseeds are an excellent source of dietary fibre, particularly soluble fibre.
The soluble fibre in flaxseeds absorbs water and forms a gel-like substance in the digestive system, which aids in promoting satiety, regulating blood sugar levels, and maintaining regular bowel movements.
The high fibre content of flaxseeds contributes to improved digestive health and may help prevent constipation.
Two tablespoons of ground flaxseeds provide about 4 grams of fibre. They are also an excellent source of omega-3 fatty acids, lignans (which have antioxidant properties), and plant-based protein.
Additional nutrient advantages flaxseeds provide:
Omega-3 fatty acids: Flaxseeds are one of the richest plant-based sources of alpha-linolenic acid (ALA), an omega-3 fatty acid.
Omega-3 fatty acids reduce inflammation, support heart health, and promote brain function.
Consuming flaxseeds can contribute to achieving an adequate intake of omega-3 fatty acids, particularly for individuals following a vegetarian or vegan diet.
Lignans: Flaxseeds are abundant in lignans, plant compounds with antioxidant and estrogenic properties. Lignans have been associated with a reduced risk of certain cancers, particularly breast, prostate, and colon cancers. Additionally, lignans may help balance hormone levels and support overall hormonal health.
Potential hormonal benefits: Flaxseeds contain phytoestrogens, which are plant compounds that mimic the effects of estrogen in the body. Phytoestrogens may help alleviate menopausal symptoms, such as hot flashes and night sweats, although more research is needed to confirm their effectiveness.
When incorporating flaxseeds into your diet, consuming them in ground form or as flaxseed oil is essential to maximise their nutritional benefits. Whole flaxseeds may pass through the digestive system undigested, reducing their potential health benefits. Adding ground flaxseeds to smoothies, cereals, yogurt, or baked goods is a convenient way to enjoy their nutritional properties.
It’s worth noting that flaxseeds are also a good source of minerals like magnesium and manganese and provide a modest amount of protein. However, consuming flaxseeds in moderation is important due to their high caloric density. Consulting with a healthcare professional or registered dietitian is recommended for personalised dietary advice and to determine the appropriate intake of flaxseeds based on individual needs.
Four: Quinoa
Quinoa is considered an excellent source of dietary fibre, with both soluble and insoluble fibre present in significant amounts.
Soluble fibre forms a gel-like substance in the digestive tract, helping to regulate blood sugar levels, improve satiety, and promote healthy cholesterol levels. Insoluble fibre adds bulk to the stool, aiding digestive regularity and preventing constipation. The fibre content in quinoa contributes to a healthy digestive system and supports overall gut health.
Additional nutrient advantages quinoa provides:
Complete protein: Quinoa is unique among plant-based foods because it is a complete protein, meaning it contains all the essential amino acids our bodies need.
