A diet high in fiber and yogurt is associated with a reduced risk for lung cancer, according to a study by Vanderbilt University Medical Center researchers published in JAMA Oncology according to Medical Express.
The benefits of a diet high in fiber and yogurt have already been established for cardiovascular disease and gastrointestinal cancer. The new findings based on an analysis of data from studies involving 1.4 million adults in the United States, Europe and Asia suggest this diet may also protect against lung cancer.

In a lot of ways fiber reminds me of what Mark Twain said about the weather. “Everybody talks about it, but nobody does anything about it.” So, here is an excellent rundown on fiber from the Tufts Health & Nutrition Letter.
It is recommended that adults consume between 25 and 30 grams of dietary fiber a day. The average American currently gets about half that amount. According to the latest Dietary Guidelines for Americans, dietary fiber is a “nutrient of public health concern,” meaning this low level of intake could actually be detrimental to our health. So, it’s potentially good news that food manufacturers are adding fiber to processed foods. But is that fiber as good for our health as fiber found naturally in fruits, vegetables, nuts, legumes, and whole grains?
Health Benefits of Fiber. According to a research review co-authored by Nicola McKeown, PhD, a scientist with Tufts’ Nutritional Epidemiology program and an associate professor at the Friedman School, there is reproducible evidence that dietary fiber found naturally in foods has a role in lowering cholesterol, improving glycemic control, and preventing constipation. And fiber may have more health benefits as well. “Research in this field is continually expanding,” says McKeown. “We’ve only begun to consider things like how the gut microbiota utilize different types of dietary fibers to potentially impact health.” Continue reading →
Unlike the weather, as in Mark Twain’s famous quote, “Everybody talks about it, but nobody does anything about it” fiber is different. Everybody talks about it and there is plenty we can do about it. Following is what the Academy of Nutrition and Dietetics has to say about it.
Fruits, vegetables, beans and whole grains all contain dietary fiber, a type of carbohydrate that provides minimal energy for the body. Although the body can’t use fiber efficiently for fuel, it’s an important part of a healthy eating plan and helps with a variety of health conditions.
Heart disease: Fiber may help prevent heart disease by helping reduce cholesterol.
Weight management: Fiber slows the speed at which food passes from the stomach to the rest of the digestive system – this can make us feel full longer. Foods that are higher in dietary fiber often are lower in calories as well.
Diabetes: Because fiber slows down how quickly food is broken down, it may help control blood sugar levels for people with diabetes by reducing blood sugar levels after meals.
Digestive issues: Fiber increases bulk in the intestinal tract and may help improve the frequency of bowel movements.
The recommended amount of dietary fiber is 14 grams for every 1,000 calories per day, or, about 25 grams for women and 38 grams for men each day. Your exact needs may vary depending on your energy needs.
Whole grains and beans tend to be higher in fiber than fruits and vegetables, but all are sources of dietary fiber and contribute other important nutrients. Make sure to include a variety of these foods regularly to meet your dietary fiber needs. These are a few tips to help increase your fiber intake from foods:
Mix in oats to meatloaf, bread or other baked goods.
Toss beans into your next salad or soup.
Chop up veggies to add to sandwiches or noodle dishes such as pasta or stir-fry.
Blend fruit into a smoothie or use it to top cereal, pancakes or desserts.
It also is important to drink plenty of water and to increase your fiber intake gradually in order to give your body time to adjust.
How much fibre people ate before they had a heart attack did not affect how long they lived after a heart attack. But people who increased the amount of fibre they ate after a heart attack were less likely to die during the study than people who didn’t increase how much fibre they ate.
After having a heart attack, people who eat foods containing fibre, in particular cereal fibre, may live for longer than people who eat less fibre.
What do we know already?
A heart attack happens when the heart doesn’t get enough oxygen and part of it dies. This usually happens when one of the vessels that take blood and oxygen to the heart is suddenly blocked.
Heart attacks are medical emergencies, which need to be treated in hospital straight away. After a heart attack, making lifestyle changes can help some people to recover and live for longer.
A previous study of people who’d had a heart attack looked at whether those who ate more foods with a lot of fibre (such as beans and lentils, wholegrain cereals, oats, fruits and vegetables) lived for longer than people who ate less fibre. It suggested fibre wasn’t linked to how long people lived after…
