How to Get More Natural Fiber

They make fiber supplements you mix up with water.

Well, I had a look at my diary going a few days back, and I often exceed 50 grams while staying within your calorie limit (give or take). Have a look if you like. I do eat a lot of fruits and vegetables and whole rye bread.

According to the experts I am supposed to be eating about 38grams of fiber each day. I find it easy to get to about 25 eating lots of fresh vegetables, beans, multigrain etc. But getting from 25 to 38 is really hard while getting my 130grams of protein and staying under 1750 calories. What would you do? Not interested in supplements.

I just started growing wheatgrass. I plan to grind it up in morning smoothies.

Kiwis are your best friends

Pumpkin purée, oatmeal, steel oats, ground flax seed, sweet potatoes, black beans, navy beans, brown rice pasta, quinoa, butternut squash, all veggies and stick with berries for fruit. Don't forget peanut butter and nuts!!

It's not 100% necessary to actually hit the 38 mark. It's an approximate number. For most people, between 25 and 35 is a comfortable place to be.

Good tips, thanks!

I played around with your suggestions and the calculator a bit and this is what I'll try (or close to it).

Breakfast:
Red mill oat bran with flax 150Cal 10g Fiber

Snack:
Apple 80cal 7g fiber

Lunch
1/2 cup beans in a salad 110 cal 7g fiber

Snack
2 carrots 60 cal 4g fiber

Dinner:
2 cups cauliflower or brocc 60cal 6g fiber

Total:
460 calories/ 34g fiber

I figure I'll the other 4 grams from other stuff.

A banana would do it.

I seem to get much of my fiber from breakfast, usually a smoothie with a banana and frozen berries. Nuts have a lot of fiber, too, though also calories of course.

Oh, and someone mentioned berries for fruit... this is a good idea. I used to eat an apple or two everyday, but now I'm having blueberries or strawberries more often. They seem to be higher fiber per calorie and they are lower in sugar. I find that strawberries, especially, can squash my cravings and up my fiber pretty quickly. Almonds and high fiber and protein, too, but they are higher calorie than some snacks. If you have room for the fat and calories, they are a great option.

One of my MFP friends posted this today:

1/2 c. pumpkin puree 1/4 c. egg whites (from an egg or carton) Sweetener Cinnamon or pumpkin pie spice Directions: 
Mix together all the ingredients. If you prefer a flan-like texture, add more pumpkin; if you prefer a cake-like texture, add more egg whites. Microwave for two minutes. Use a mix of Greek yogurt, hazelnut cream cheese, and pumpkin pie spice for the icing. Top with toasted pecans. Makes one serving.

You could do the same thing with sweet potatoes instead of pumpkin.

I am not one for supplements and it is always better to get what your body needs from foods. Get some oat bran and you can add to yogurt or make into porridge or make cookies. The list of ways to use oat barn is endless. Enjoy!

Supplements are exactly that: to SUPPLEMENT your food when, as was stated, you can't get fulfill your nutritional needs with diet alone. That said, there's no reason you shouldn't be able to get enough fiber from your diet. All more vegetables and fruits and you'll be good.

Just one thing I thought I would throw in -- the fiber recommendation varies depending on how many calories you are eating. If you are eating fewer calories, you need fewer grams of fiber. The suggested intake is 14 g of fiber per 1000 calories. You may know this already, I can't really tell, so forgive me if I am boring you with this! But a lot of websites just give the standard fiber numbers without stating they are derived based on the assumption that people are eating the standard recommended amount of calories.
I usually aim for about 1500 calories a day, so my recommended fiber intake is a minimum of 21 g. If you are eating under about 2700 calories per day, you may not need as much fiber as the "one size fits all" fiber page is telling you that you need. Not that there is anything wrong with eating lots of fiber, of course!
