Research Round-Up: Saturated Fats & Lung Cancer; Almonds & “Good” Cholesterol
Saturated Fats Raise Lung Cancer Risk
An analysis of 10 studies from the US, Europe, and Asia, identified 18,822 patients with lung cancer over a mean follow-up of about nine years. High intakes of total and saturated fat were associated with an increased risk of lung cancer, while high intake of polyunsaturated fats showed a decreased lung cancer risk. The increased risk in high saturated fat consumption was more evident among current smokers than non-smokers and for squamous and small cell carcinoma.

Almonds Improve “Good” Cholesterol
Eating almonds every day increases HDL (“good”) cholesterol levels and improves its function in the body, according to researchers. In two separate six-week diet periods, which involved 48 men and women with elevated LDL (“bad”) cholesterol, diets were the same except one group snacked on a handful (43 grams) of almonds, while the other snacked on a banana muffin. The almond snackers’ HDL increased by 19 percent and improved cholesterol function (gathering cholesterol and helping transport it from the body) by more than six percent.

Sugary Drink with Protein Meal Packs on Pounds
During this study, 27 healthy adults ate two meals with 15 percent protein one day and two meals with 30 percent protein the next. Participants drank a sugary drink with the first meal each day and a sugar-free drink with the second. The sugared drink reduced the breakdown of fats by an average of 7.2 grams in the 15 percent protein meal, and 12.6 grams in the 30 percent protein meal, compared to the sugar-free drink, showing the impact of the sugared drink on metabolism when paired with a higher protein meal.
