Mushrooms are rich in vitamins, nutrients and antioxidants. The team’s findings show that these super foods may also help guard against cancer. Even though shiitake, oyster, maitake and king oyster mushrooms have higher amounts of the amino acid ergothioneine than white button, cremini and portabello mushrooms, the researchers found that people who incorporated any variety of mushrooms into their daily diets had a lower risk of cancer. According to the findings, individuals who ate 18 grams of mushrooms daily had a 45% lower risk of cancer compared to those who did not eat mushrooms.

Veg Out For Your Heart
5 Fruits and Veggies a Day May Be Optimal for the Greatest Mortality Benefit
Five servings of fruits and vegetables a day — in particular, three vegetables and two fruits — provide the greatest mortality benefit, according to an observational study and meta-analysis in Circulation.
Researchers analyzed results from the Nurses’ Health Study and Health Professionals Follow-Up Study. Over 100,000 people regularly completed food-frequency questionnaires and were followed for up to 30 years. During that time, nearly a third of participants died.
After multivariable adjustment, the greatest mortality benefit was seen for five servings of produce a day, compared with two servings (hazard ratio, 0.88). Eating more than five servings a day was not associated with greater risk reductions.

Five Simple Guidelines for Good Vegan Nutrition
1. Eat at least three servings per day of beans, tofu, tempeh, soy milk, veggie meats, peanuts or peanut butter.
2. Consume a wide variety of fruits and vegetables, including leafy greens and dark orange vegetables plus good sources of vitamin C like peppers, citrus fruit, and strawberries.
3. Get most of your fat from healthy sources, like nuts and nut butters, avocados, seeds, and moderate amounts of oils. Be sure to eat a good source of the essential omega-3 fat ALA found in flaxseed, hempseed, canola oil, and walnuts.
4. Eat three cups of calcium-rich foods every day including fortified plant milks, fortified juices, tofu made with calcium sulfate, and cooked kale, collards, bok choy, or turnip greens (double the amount of greens if you eat raw greens instead of cooked).
5. Don’t shun supplements. All vegans need vitamin B12 from supplements or fortified foods. Most also need a supplement of vitamin D, at least during the winter months. You may wish to consider vegan DHA and EPA supplements. If you don’t regularly use iodized salt, it’s prudent to take an iodine supplement. Vegan.com maintains a supplements page that provides current and helpful information for all these nutrients.

The PREDICT 1 Study – Link between Gut Microbes, Diet and Illnesses Revealed
The PREDICT 1 (Personalized Responses to Dietary Composition Trial 1) analyzed detailed data on the composition of participants’ gut microbiomes, their dietary habits, and cardiometabolic blood biomarkers. It uncovered strong links between a person’s diet, the microbes in their gut (microbiome) and their health.
Researchers identified microbes that positively or negatively correlate ‘good’ and ‘bad’ with an individual’s risk of certain serious conditions such as diabetes, heart disease and obesity. Surprisingly, the microbiome has a greater association to these markers than other factors, such as genetics. Some of the identified microbes are so novel that they have not yet been named.

Eat More Carrots – VRG Scientific Update
Researchers began studying close to 50,000 women in 1984 when their average age was 48 years old. They collected information about the women’s diets over the next 22 years. The women’s cognitive function was assessed at 28 or 30 years after the start of the study. At that point, 41% had good cognitive function, 47% had moderate function, and 12% had poor function. Women who had the highest long-term intake of total carotenoids were 33% less likely to have poor cognitive function and 14% less likely to have moderate cognitive function than those who had the lowest intake. The same results occurred when the researchers examined individual carotenoids.

An Avocado a Day Keeps Your Gut Happy
The researchers found that people who ate avocado every day as part of a meal had a greater abundance of gut microbes that break down fiber and produce metabolites that support gut health. They also had greater microbial diversity compared to people who did not receive the avocado meals in the study.

Eat More Dried Fruit
The researchers found that people who ate dried fruit were generally healthier than those who did not, and on days when people ate dried fruit they consumed greater amounts of some key nutrients than on days when they skipped. However, they also found that people consumed more total calories on days when they ate dried fruit.
Previous research has found that poor diet contributes to nearly half of deaths from cardiovascular disease in the U.S., with a lack of fruit being a major factor. According to the researchers, fruits provide an abundance of nutrients, including fiber, potassium and several heart-healthy bioactives.

Does Olive Oil Lower Cardiovascular Risk in U.S. Populations?
Does Olive Oil Lower Cardiovascular Risk in U.S. Populations?
Definitely maybe.
This study confirms what most of us likely recommend to our patients — replace saturated fats with olive oil. The CVD prevention benefit of olive oil seems to extend to all populations, including Americans, who consume far less olive oil on average than Mediterranean populations. As with all observational studies, residual confounding might explain some of the associations, and the healthcare professionals studied may not be generalizable to other more diverse groups. However, results from the PREDIMED trial (N Engl J Med 2018; 378:e34) support this well-conducted study. Recommending routine use of olive oil seems like a no-brainer.
Walnuts may be good for the gut and help promote heart health
Walnuts may be good for the gut and help promote heart health
In a randomized, controlled trial, researchers found that eating walnuts daily as part of a healthy diet was associated with increases in certain bacteria that can help promote health. Additionally, those changes in gut bacteria were associated with improvements in some risk factors for heart disease.
