After just 14 days of eating a healthier diet, women’s blood was able to slow down breast cancer cells growing in petri dishes—killing 20–30% more cancer cells than before the diet change. Researchers linked this effect to lower levels of IGF-1, a cancer-promoting growth hormone.
People eating plant-based diets for 14 years have half the amount of IGF-1 in their bodies and more than twice the IGF-binding protein than those eating a more westernized diet.
What benefits do lifestyle changes have on breast cancer survival?
➡️ A significant breast cancer survival advantage is associated with eating five or more servings of fruits and vegetables a day and walking about 30 minutes a day, six days a week.
➡️ Randomized studies show that when people with early-stage breast cancer lower their saturated fat intake, there is an increase in breast cancer survival.
➡️ A higher fiber diet was associated with a 37% lower risk of dying from all causes put together and a 28% lower risk of dying specifically from breast cancer (among breast cancer survivors). There was about a 10% drop in death risk for every increment of 5 daily grams of dietary fiber.
🥦 That’s like 1 cup of oatmeal or broccoli, or just 1/3 cup of beans, a day.
The diet that helps prevent cancer also helps prevent heart disease. By living and eating more healthfully, we can increase our chances of living a long, healthy life.
