How Much Fiber Per Day? Grams, Sources, Benefits, and More

Guidelines advise different amounts of fiber depending on your age and sex. As you age, your fiber needs may go down.

According to the Food and Drug Administration, the Daily Value for fiber is 28 grams per day for adults on a 2,000-calorie diet. This number may also depend on age or sex.

The USDA’s Dietary Guidelines for Americans suggest the following amounts of fiber:

• Women under 50: 25 to 28 grams per day
• Men under 50: 31 to 34 grams per day
• Women 51 and older: 22 grams per day
• Men 51 and older: 28 grams per day

Children ages 1 to 18 should eat 14 to 31 grams of fiber per day, depending on their age and sex. Even higher fiber intakes, seen in countries around the world, may significantly reduce chronic disease risk.

Fiber does digestive grunt work but doesn’t get the same glamour as vitamin D, calcium, and other nutrients.

It’s important to get the right amount of fiber to keep your digestive system running smoothly. Fiber also provides a lot of health benefits beyond digestion, such as help with weight loss and with balancing gut bacteria.

The average American eats only about 16 grams of fiber per day. That’s quite a bit less than the daily recommended intake for a lot of people. Read on to learn more about the benefits of fiber, where to get fiber, symptoms of consuming too much fiber, and more.

As a whole, fiber delivers a lot of health benefits:

• supports weight loss
• reduces cholesterol and blood sugar levels
• lowers risk of cardiovascular diseases such as stroke, heart disease, and more
• lowers risk of diabetes
• increases digestive and bowel health
• fuels healthy gut bacteria
• may lower risk of colorectal and breast cancer

In general, “dietary fiber” is an umbrella term for the parts of plants and other foods that your body can’t digest. Your body does not break down fiber. Instead, fiber passes through your system and eases symptoms such as constipation.

It’s important to eat a wide variety of foods instead of relying on one source for fiber intake.

The best way to get fiber without consuming too many calories is to eat high fiber foods. Most vegetables, fruits, and other plant-based foods contain fiber.

If your body is slowly adjusting to more fiber, spread out your portions across multiple meals instead of eating a lot in a single serving.

Here are more high fiber foods to try:

Fiber-rich foods	Grams (g) per serving size
split peas, cooked	16.4 g per cup
lentils, cooked	15.6 per cup
black beans, cooked	15.4 per cup
lima beans, cooked	9.2 g per cup
green peas, cooked	8.8 g per cup
raspberries	8 g per cup
cooked barley	6 g per cup
oat bran	6 g per cup
medium pear with skin	5. 6 g per pear
medium apple with skin	4.8 g per apple
bran flakes	5.5 g per 3/4 cup
cooked Brussels sprouts	6.4 g per cup
almonds	3.6 g per 1 oz.
chia seeds	8.4 g per 1 oz. (2 tbsp.)

Fiber is a type of carbohydrate that comes in three main forms: soluble, insoluble, and fermented fiber.

• Soluble fiber dissolves in water and slows down digestion. It can help lower your cholesterol and blood sugar levels.
• Insoluble fiber doesn’t dissolve in water and plays a different role in digestion. It adds bulk to stool and passes through your system more quickly. Basically, it helps keep your pipes working regularly and prevents constipation.
• Fermentable fiber can come from either of the previous two categories, although it is more often soluble fiber. Fermented fiber helps increase the healthy bacteria in your colon.

It’s best to gradually add fiber to the diet. You don’t want to shock your system with too much bulk. “Start low, go slow,” as the International Foundation for Functional Gastrointestinal Disorders puts it.

Here are some tips for adding fiber — but not too much:

• Eat whole fruits such as pears and apples instead of drinking fruit juices.
• Opt for whole grain foods instead of white rice, white bread, and white pasta.
• Snack on vegetables instead of pretzels and chips.
• Eat beans and lentils daily.
• Sprinkle chia seeds on cereal, smoothies, or salads.
• Make sure you’re drinking plenty of water when you eat fibrous food.

You may also find it helpful to track the foods you eat and note the fiber content to better understand how much you’re actually eating. Some people who find it hard to eat enough fiber may want to consider taking a fiber supplement.

That said, too much fiber can also be a bad thing. And your body will speak up (literally and figuratively) with a variety of symptoms if you’re eating too much of it. Fiber supplements have also not been found to be nearly as beneficial as eating high fiber foods.

Keep in mind that everyone’s body reacts to fiber a bit differently. Some people with a condition called irritable bowel syndrome may not tolerate fiber well.

Fiber is also known as “bulk” or “roughage,” and it can make some noise as it passes through your stomach and intestines. While there is no daily upper limit for dietary fiber intake, consuming large amounts may cause discomfort and symptoms such as:

• gas
• bloating
• constipation
• diarrhea
• abdominal cramping

Cut back on your fiber intake if you experience these symptoms and feel that they are the result of your diet and not another condition, like the stomach flu, that has similar symptoms.

If you experience severe symptoms, consult your doctor or visit an urgent care center or the hospital. In rare but serious cases, consuming too much fiber can cause an intestinal (bowel) obstruction, which is a blockage that prevents contents from moving through.

Fiber in the diet: how much and why?

Fiber is a polysaccharide that is a structural part of a plant, its cell. If you look at such a cell under a microscope, you will see long filaments that fill the space of the cell – fibers. Therefore, fiber is also called dietary plant fiber.

How does fiber work?

1. Reduced GI of foods, blood sugar and insulin levels
2. Overeating help
3. Help with constipation
4. Food for intestinal bacteria
5. Natural sorbent

Fiber Guidelines

Modern nutritionists and nutritionists recommend 30 to 50 grams of fiber per day for an adult. For children: 10 grams + 1 gram for each year of life. That is, for a child of 10 years old, the norm of fiber will be 20 grams / day.

Is added fiber needed?

Now let’s talk about the added fiber and the nuances of its use.

First, is added fiber really necessary? There has been a lot of controversy on this topic lately. Judge for yourself. Ideally, dietary fiber should come from a variety of foods – fruits, vegetables, herbs, cereals, legumes, nuts. The key is that it should be a variety of whole plant foods that have not been industrially processed or minimally processed. However, in fact, the diet of the average city dweller is oversaturated with animal products, in which there is no fiber at all, as well as refined plant products. It’s all white: white bread, white rice, white sugar, white pasta. Refining is detrimental in that it removes the most valuable fiber from the product. With regard to whole plant foods, they are present in diets either in insufficient quantities or are processed to reduce the amount of fiber in them (squeezing juice, cooking jam, etc.). The fiber content in some products, so that you can navigate: in 200 grams of buckwheat porridge there is only 5 grams of fiber, in 100 grams of greens – 2 grams, in 100 grams of carrots – 2. 4 grams Obviously, with such a nutritional pattern, the introduction of additional fiber is necessary.

How to use added fiber without gastrointestinal consequences?

Let’s start with contraindications. They are: gastric ulcer in the active stage, colitis and enterocolitis. Pregnancy and breastfeeding are not contraindications.

More is not better. It is a mistake to think that the more fiber you eat, the more benefits you will get. Moreover, eating more than 50-60 grams of fiber per day (meaning all the fiber in a day: from foods + added) can cause bloating and gas. Also, excess fiber impairs the absorption of trace elements from foods. Dietary plant fibers, consumed in large quantities, accelerate the movement of food through the gastrointestinal tract, reducing the absorption of nutrients by the intestinal walls. The body simply does not have time to absorb the right amount of nutrients before the food leaves it. However, if the recommended dose is observed and taken in courses, this effect is not observed

How much fiber is needed for health?

Margarita Provotorova, leading expert of the CMD Center for Molecular Diagnostics, explains.

Fiber is one of the few substances in food that our body is not able to digest, and its nutritional value, to put it mildly, is not high. It would seem that eating it is useless. Nevertheless, both doctors and medical experts do not get tired of talking about the importance of fiber content in the diet.

How much to hang in grams?

Adults need at least 30 g of this complex carbohydrate daily to maintain health. Alas, in our country, the average fiber intake is usually less than half the recommended amount – only about 12-15 g. Such figures are worrying. After all, diet has a huge impact on health.

Here’s an example: 30 g of fiber reduces the risk of cardiovascular disease and its complications, such as heart attack and stroke. The substance takes part in cholesterol metabolism, lowering it, and also affects blood sugar metabolism. This reduces the risk of developing type 2 diabetes. Fiber is also indispensable for normal bowel function – due to the sufficient content of dietary fiber, stools are normalized. There is evidence that a sufficient carbohydrate content in food is the prevention of colorectal (colon) cancer.

And, especially during the cold season, a fiber-rich diet contributes to the health of the immune system, reduces the number of infectious, including respiratory, diseases. It is thanks to dietary fiber that our microbiome can fully function and produce beneficial bacteria. For the normal activity of lactobacilli, dietary fiber is also necessary. They have a healing effect on the intestines due to the fiber substrate.

If you’re watching your weight or worry about gaining extra pounds, consider what’s on your menu and whether it’s high in fiber. Studies show that if you add an additional 10 g of fiber to your diet, the likelihood of gaining weight decreases.

What healthy foods will help you get the optimal amount of fiber?

1. Try to eat whole grain bread, and eat white from premium and 1st grade flour as little as possible.
2. Choose whole fruits. It is better to eat an apple than to drink a glass of juice. Alas, these drinks, especially without pulp, contain very little fiber.
3. Prefer pasta? Choose whole grain varieties.
4. Give preference to unpolished cereals. For example, brown rice is much healthier than polished white rice.
5. Legumes, such as beans, chickpeas, lentils, must be regularly present on your table.
6. Snack not on chips and cookies, but on healthy snacks – slices of vegetables or fruits. Cut carrots, broccoli, cauliflower, add yogurt sauce or hummus, top with cereal bread.
7. Record holders for fiber content among berries are raspberries, blackberries and gooseberries. Yes, the season for fresh berries is short, but their frozen version is perfect for autumn and winter.
8. Do not forget about one of the main rules of a healthy diet – five servings of fresh vegetables and fruits daily. But do not rush to get rid of the feijoa peel, peel an apple or a pear. Their outer shell is very rich in fiber.
