Good Health Isn’t Always Just Luck

Many people have at least one superstition that influences their behavior or well-being. But finding a heads-up penny from the year you were born won’t increase your longevity or reduce the risk of disease if you’re not eating a healthful diet.

A low-fat, plant-based diet is associated with lower risks of heart disease and diabetes. However, a recent study from the American Institute for Cancer Research shows that fewer than half of Americans know that a diet high in plant-based foods can reduce cancer risk. And despite the mountain of evidence showing a link between red and processed meat and colorectal cancer, only 35 percent of Americans are aware of the risks that come with eating hot dogs and bacon.

Superstitions can be murky, but the science is clear. Here are some studies published within the past three months that link plant-based diets to disease prevention:

Vegetarian Diet Protects Against Colorectal Cancer
Vegetarian Diet Leads to Weight Loss
Whole Grains Protect Against Heart Disease
Vegetarian Diet Reduces the Risk of Heart Attack
Plant-Based Diet Reverses Angina
Plant-Based Diets Lower Risk of Heart Disease in Obese Children
High-Fiber Diets Increase Lifespan

Good health isn’t just dumb luck. Fortunately, we can empower ourselves with the knowledge that we can influence our risk of disease. Just fill your plate with fruits, vegetables, whole grains, and legumes.

Foods that Fight Depression

This is a guest post from Ulka Agarwal, M.D.

As a psychiatrist, my patients often ask me if there are dietary changes they can make to improve their depression. Many cannot tolerate antidepressants, don’t benefit from them, or are reluctant to try medications or seek counseling due to stigma. As a result, they miss an average of 19 work days per year, costing employers up to $44 billion dollars a year in lost productivity. Depression can aggravate other chronic illnesses as well, like diabetes and heart disease. We know that plant-based diets prevent and even treat these chronic illnesses, but can they also improve mood? Our recent study published in the March/April issue of the American Journal of Health Promotion demonstrates how a plant-based nutrition program improves not only depression, but anxiety, fatigue, productivity, and other markers of well-being.

This 18-week study analyzes the health benefits of adopting a plant-based vegan diet in a corporate setting. Study participants, GEICO employees who were either overweight or struggling with type 2 diabetes, adopted a low-fat vegan diet, favoring high-fiber, low-glycemic foods. They learned about preventive nutrition and new cooking tips through weekly “lunch and learn” sessions led by a clinician or cooking instructor. They also formed bonds, sharing helpful health tips along the way and connecting with the group on a daily basis through an online forum. Study participants alleviated symptoms of anxiety, depression, and fatigue, and improved their productivity both at work and outside of work, according to the 36-Item Short Form Health Survey (SF-36) and the Work Productivity and Activity Impairment Questionnaire (WPAI):

They also lost an average of 10 pounds, lowered LDL cholesterol levels by 13 points, and improved blood sugar control, if they had type 2 diabetes. When people improve their physical health they become more physically and socially active and their overall quality of life improves.

How does a plant-based diet improve depression? Depression is related to inflammation in the body and low levels of serotonin. Plant-based foods naturally lower inflammation in the body because they are naturally low in fat and high in antioxidants. High vegetable intake increases the amount of B vitamins in the diet, which have been found to affect mood.

So what are you waiting for? Jump right in with a low-fat, plant-based diet! It’s the best prescription to boost your mood, energy, and productivity, while reducing your risk for chronic illnesses. I know I’ll be prescribing a plant-based diet to all of my patients for their emotional and physical well-being.

Fiber is the Key to Good Health

regular-people-FB

Fiber plays a key role for digestion, weight loss, and cancer prevention, and can even increase lifespan! But don’t be fooled—many packaged food companies are trying to boost sales by adding extra fiber to their gummy candy or yogurt, but the best source of fiber is plants themselves! Yes, natural fiber is found only in fruits, vegetables, whole grains, and legumes. So make sure you’re filling your plate with whole, plant-based foods.

What is fiber?

There are two types of fiber: soluble and insoluble. Soluble fiber is found in oats, beans and other legumes, and some fruits and vegetables. Soluble fiber lowers cholesterol levels. Insoluble fiber—found in whole grains, fruits and vegetables, kidney beans, and bran—acts like a broom, cleaning your digestive tract.

Both types of fiber are only found in plant foods—meat and dairy products contain no natural fiber. Don’t be fooled by yogurts that prominently advertise their fiber content! That fiber was added during processing. Since dairy products are high in saturated fat and cholesterol, skip the yogurt and head to the produce aisle. Just one cup of raspberries has 8 grams of fiber! One cup of red lentils has 16 grams of fiber—and 18 grams of protein.

Weight Loss

If you’re looking to lose weight, filling up on fiber-rich foods is your best bet. My colleagues and I recently published a study in the Journal of the Academy of Nutrition and Dietetics showing that simply switching to a plant-based diet leads to significant weight loss, without any calorie counting or exercise.

Cancer Prevention

Not only can fiber help you shed pounds or relieve your digestive woes, it can decrease cancer risk. By improving the intestinal transit of food and waste, fiber helps your body eliminate carcinogens. The U.S. Polyp Prevention Trial also found that a high-fiber diet reduced the occurrence of colon polyps. A meta-analysis published in the Journal of the National Cancer Institute examined 13 studies and found that the risk of colorectal cancer decreased as fiber intake increased.

How Can I Get Enough Fiber Each Day?

I recommend a dietary intake of 40 grams of fiber per day—while most Americans are only getting 10-15 grams. But there’s no need to count. It’s easy to boost your fiber content with a few easy swaps. Trade white bread for whole grains. Ditch sugary cereals for heart-healthy oatmeal. Add some fruit to your breakfast or grab an apple or banana when you’re in a hurry. Make sure that everything on your plate has at least a little bit of fiber. Most importantly, skip the animal products. When your menu is plant-strong, you’ll be getting the fiber you need.
