15 Best Fiber-Loaded Foods You Should Start Eating Every Day Over 40 For Reduced Inflammation & Weight Loss, Dietitians Say: Oatmeal, Sweet Potatoes, More

Fiber has so many benefits, so it’s essential to get enough of it in your diet – especially once you reach the age of 40! Diets packed with fiber are associated with a lower risk of type 2 diabetes , heart disease , stroke , and bowel cancer , not to mention being great for digestion , reducing bloating , and preventing constipation.

As well as having many health benefits and helping you maintain a healthy digestive system, a fiber-rich diet is great for the waistline too. Foods with plenty of fiber can make you feel fuller for longer, therefore stopping snacking on unhealthy foods between meals.

Some of these foods include fruits, vegetables, whole grains, and legumes, and contain both soluble and insoluble fiber, which work together to support overall gut health and contribute to overall well-being. Take a look at 15 of the best fiber-packed foods recommended by dietitians and health experts for reduced inflammation, healthy digestion, and weight loss below…

1. Avocado

"Avocado is one of the healthiest fats on the planet. It is very high in monounsaturated fats as well as dietary fiber. It is also a great source of B vitamins, vitamin C, vitamin E, vitamin K, folate, potassium, magnesium, and antioxidants. The healthy fats in avocado is great for supporting brain health as well as proper blood lipid levels which is essential for heart health," Jesse Feder, RDN, CPT says.

He also notes that the abundant dietary fiber in avocados plays a crucial role in supporting the gastrointestinal tract, enhancing nutrient absorption, and promoting overall health. Furthermore, the copious nutrients and antioxidants present in avocados prove beneficial in optimizing bodily functions and combating inflammation.

2. Oats

Oats are rich in both soluble and insoluble fiber. Soluble fiber forms a gel-like substance in the digestive tract, which helps slow down digestion, promotes nutrient absorption, and stabilizes blood sugar levels.

"Oatmeal with chia seeds is an ideal high-fiber, high-protein breakfast for weight loss due to its nutritional composition," Lisa Richards, nutritionist and creator of The Candida Diet, says. "This nutrient-dense breakfast supports weight loss by fostering a sense of fullness, promoting digestive health, and supplying essential nutrients for overall well-being."

3. Nuts

Nuts' fiber content helps digestive health by supporting proper digestion and preventing constipation.

"Nuts are a great source of both insoluble fiber and healthy fats," Feder shares. The beneficial fats and fiber content in nuts are effective for lowering harmful cholesterol levels while boosting the beneficial ones, thereby mitigating the risk of artery blockages and enhancing cardiovascular well-being. Nonetheless, Feder cautions individuals mindful of their weight: "It is important to only have one or two handfuls of nuts due to them being very calorically dense."

4. Lentils

Lentils are a nutritional powerhouse and a top choice for maintaining digestive health. Their rich fiber content aids in regulating digestion, promoting regularity, and alleviating digestive discomforts commonly experienced in many individuals.

"The high fiber content in lentils can promote healthy digestion by supporting regular bowel movements and the growth of healthy gut bacteria. Additionally, the combination of protein and fiber in lentils can support stable blood sugar levels, which can help reduce cravings and aid in fat loss," Joanna Wen, certified weight loss coach and founder of Spices & Greens, says.

5. Barley

Barley stands out as a high-fiber food with significant benefits for digestive health. Rich in both soluble and insoluble fiber, barley aids in maintaining healthy cholesterol levels, lowering the risk of heart disease. Moreover, barley's fiber content helps stabilize blood sugar levels, further supporting overall well-being.

"These fibers help in decreasing gut inflammation by enhancing the growth of healthy bacteria," Dr. Erik Natkin says when it comes to whole grains such as barley.

6. Spinach

Spinach, the vibrant leafy green beloved by many, is not just a culinary delight but also a secret weapon for maintaining digestive wellness. Bursting with fiber, spinach offers a double dose of health benefits. Its soluble fiber content aids in managing cholesterol levels , a crucial aspect of heart health as we age. Meanwhile, the insoluble fiber in spinach keeps digestion running smoothly, combating common digestive issues that often arise down the line.

Feder says this green food is "loaded with fiber and other nutrients including vitamins A, C, K, folic acid, iron, and calcium. The high amount of antioxidants is great for fighting off inflammation throughout the body, including your brain, and heart. The high amount of fiber promotes healthy digestion and nutrient absorption which is also important for whole body health. Lastly, the key nutrients in spinach has been directly associated with improvements in cognition and cardiovascular health."

7. Chia Seeds

Chia seeds, a small but mighty superfood, are an exceptional choice for nurturing digestive health. The insoluble fiber aids in digestion, easing common digestive discomforts. "Chia seeds expand and form a gelatin type substance in the digestive tract. This is great for slowing down digestion, increasing nutrient absorption, and helping you feel full for long periods of time," Feder says.

"They are also powerful seeds that are bursting with protein, fiber, calcium, iron, and omega-3 fatty acid," Sheri Berger, RDN, CDCES, tells us. "A 2021 review found chia seeds help to increase high density lipoprotein (HDL), also known as good cholesterol and lower low density lipoprotein (LDL), also known as bad cholesterol."

8. Popcorn

The fiber in popcorn promotes a feeling of fullness and satisfaction without excess calorie intake, making it suitable for individuals monitoring their weight. As a complex carbohydrate , popcorn undergoes slow digestion, providing a steady release of energy throughout the night and helping to stabilize blood sugar levels.

Destini Moody, RD, says that "in terms of calories per serving, popcorn is arguably one of the best snacks for weight loss because it takes up a relatively small amount of volume in the stomach, making you feel full without going over your calorie budget." She also adds that "about 3 cups of air-popped popcorn is only 100 calories and contains nearly 4 grams of insoluble fiber, making it a perfect high-fiber, nighttime snack."

9. Raspberries

Raspberries are an excellent choice for a pre-bedtime snack to support digestion. Additionally, raspberries are rich in antioxidants, such as flavonoids and polyphenols, which have anti-inflammatory properties and may protect against digestive issues. Their high water content contributes to hydration, essential for maintaining healthy digestion, especially during sleep when dehydration can occur.

With just 65 calories, Moody says, "One cup of raspberries contains about 8 grams of fiber, and they can make for a refreshing, low-calorie snack when you have a sweet tooth. Eating raspberries before bed is a much better alternative to other snacks high in refined sugar, and the fiber content in berries can help with digestion as well as better blood sugar control."

Whether savored solo, blended into a nourishing smoothie, or sprinkled over your evening yogurt, raspberries offer both a tasty treat and a boost for your digestive well-being.

10. Artichokes

Don't sleep on the power of artichokes! According to Alanna Kate Derrick, sports nutrition coach: "Artichokes are another all-star bloat-buster, providing around 10g of fiber per medium artichoke." Not bad at all! She notes that "the specific type of fiber artichokes contain actually feeds the good bacteria in your gut, improving overall digestion."

If you're looking to fit more artichoke into your diet, she recommends grilling artichoke hearts or enjoying steamed artichoke leaves dipped in zesty yogurt-based sauce. Sounds delicious!

11. Okra

Dr. Sarah Mathis, a board-certified physician, says that the often-overlooked okra is one high-fiber food you can snack on while you're on your weight loss journey. "It is so slimming and packed full of fiber!" she raves. And it's great for your digestive health, too. "Okra helps to slow down your digestion while also helping to 'clean' everything out," she continues.

If you're looking to get more okra in the diet, Mathis offers some advice. "Its taste is hidden when blended into smoothies or even healthy desserts," she says. "Or, you can add it into your soups or stews or even air fry it and make it super crispy!" Doesn't that sound tasty? Of course, you'll want to avoid breaded and oil-fried okra which can actually cause more fat buildup.

12. Sweet Potato

We love sweet potatoes and all of their health benefits —including the high fiber content. Moody offers one word of advice regarding this veggie: "Don't make the mistake of peeling your potatoes if you want to increase your fiber intake!"

You can mash the peels into mashed potatoes or eat them like they are – half of the potatoes' fiber is in the peel, so it can add a nice texture to your dishes. "Furthermore, potatoes cause a more profound feeling of fullness than other carbohydrate sources and may even be more satiating than some lean proteins, according to studies done on satiety."

13. Bananas

A great source of lasting energy, bananas are one of the best fibrous carbs to include in your day-to-day diet for a faster metabolism and less bloating. There's a common misconception that because bananas are higher in calories than most fruits that they're not good for you, but in fact they can provide more lasting energy than most, making them a great addition to your diet for weight loss.

"There is a strong association between higher fiber intake and lower body weight. This is so since the body requires more time to digest fiber. For this reason, eating fiber keeps you full for a longer time and one doesn't feel hungry and therefore, it becomes easier to avoid unhealthy snacking," notes Clara Lawson, RDN.

For bananas in particular, you'll find that green bananas are actually the best option for weight loss, improving satiety over time. "Green unripe bananas might be more beneficial for losing weight since they have resistant starch, which is a carbohydrate that doesn't digest easily. Eating two bananas regularly in your breakfast is highly recommended after 2 glasses of water," says Lawson. Pair your banana with a source of protein such as eggs in the morning and you have a filling and delicious breakfast perfectly tailored for weight loss.

14. Pears

If you're craving fruit, pears make a fantastic, fiber-packed option. "In addition to soluble fiber, pears also contain insoluble fiber," Moody tells us.

"Additionally, they contain pectin, a fiber that can boost immune function, improve gut health, and prevent constipation. Just one medium pear contains just 100 calories and 6 of fiber, making them a great snack between meals for those trying to lose weight." Sign us up!

15. Beets

Beets are another high-fiber food that can help reduce fat accumulation. This root vegetable contains 3.4 grams of fiber, which can help relieve any digestive issues and lose weight.

"Beets are high in fiber and can help with digestion, owing to their Betaine which is a digestive enzyme," Dana Ellis Hunnes, PhD, MPH, RD, says. She notes that beets can help with hydration as well. "As we get older, we tend to drink less and stay less well-hydrated, which can stop us up," she continues. "[High-fiber] foods can really help, especially when they come from fresh vegetables, whole grains, fruits, etc, because they contain moisture in them as well." Noted!
