Your english is so good that it never occurred to me that you might be translating! I hadn't considered that you might be counting beans in as veggies - they are very high in fibre, so definitely might be what is putting you at the top or over some days.
The general recommendation for healthy adults is based on a 2000 calorie per day diet and is 25g-35g. For those of us with different medical conditions, we may need more or less. As we age and have a lower calorie requirement, the recommendation can change (eg. 21g for women 50 and older). The trick is to figure out what works the best for you personally, and working with your medical provider or dietitian can really help.
As has been mentioned, the more fibre that you have, the more water you should be drinking with it. Also, increases in fibre intake should be gradual, as your body will take some time to get used to processing it. The same with any large decreases in fibre - your body will need some time to get used to functioning without it.
If you are currently eating up to 45g of fibre per day, and your body is functioning well at this level, then I would think that it's not something that you should be concerned about. If you are having issues with constipation or diarrhea, then you should have a look at the amount of fibre and make some adjustments.
@ those trying to increase fibre:
With my medical situation, I ended up increasing my fibre intake from virtually nil (low residue diet) up to the current 30g-45g over the period of a year. I am a huge veggie fan, but the majority of my fibre comes from grains.
Yesterday is a good example at 41g fibre for the day:
Breakfast was oatmeal with add'l 2 Tbsp each of oat bran and wheat germ with 1/2c blueberries for a total of 10g fibre
Lunch was 2c raw cauliflower with tomato meat sauce (includes onions, mushrooms, and broccoli) for a total of 7g fibre
Dinner was a chicken strata (crustless quiche - includes steel cut oats and oat bran, along with onions, mushrooms, and broccoli) for a total of 5g fibre
Snacks were carrots (3g fibre), yogurt with cocoa powder and hemp hearts (3g fibre), muffin with crunchy peanut butter (3g fibre), popcorn (7g fibre), and hot cocoa (4g fibre)
For any other Canadians looking for an easy, tasty fibre add: Fry's Cocoa Powder is 2g of fibre per Tbsp! You can see how much I have to suffer to get enough fibre --- the sacrifice of having to flavour my yogurt with cocoa or have a hot chocolate or eat popcorn
(Somehow I'm thinking I'm not going to get a lot of sympathy on this...)
Seriously, I found that the easiest way for me to add fibre is to add a couple of tablespoons of oat bran, or wheat germ, or cocoa powder to almost everything. That 2g or 3g of additional fibre in everything really adds up quickly, and they aren't a ton of additional calories.
