Many of us give thanks for our health on Thanksgiving. Well, let’s follow through with this theme. While eating healthy may be furthest from our minds during the holidays, it is so important.

Instead of making Thanksgiving a holiday of regret, eating foods that cause weight gain, fatigue and that increase your risk for chronic diseases, you can reverse this trend while maintaining the traditional theme of what it means to enjoy a festive meal.

What can we do to turn Thanksgiving into a bonanza of good health? Phytochemicals (plant nutrients) called carotenoids have antioxidant and anti-inflammatory activity and are found mostly in fruits and vegetables. Carotenoids make up a family of more than 600 different substances, such as beta-carotene, alpha-carotene, lutein, zeaxanthin, lycopene and beta-cryptoxanthin (1).

Carotenoids help to prevent and potentially reverse diseases, such as breast cancer; amyotrophic lateral sclerosis, also known as Lou Gehrig’s disease; age-related macular degeneration; and cardiovascular disease — heart disease and stroke. Foods that contain these substances are orange, yellow and red vegetables and fruits and dark green leafy vegetables. Examples include sweet potato, acorn squash, summer squash, spaghetti squash, green beans, carrots, cooked pumpkin, spinach, kale, papayas, tangerines, tomatoes and Brussels sprouts.

Let’s look at the evidence.

Breast cancer effect

We know that breast cancer risk is high among women, especially on Long Island. An American woman has an average risk of 12.4 percent for getting breast cancer (2). Therefore, we need to do everything within reason to reduce risk.

In a meta-analysis (a group of eight prospective or forward-looking studies), results show that women who were in the second to fifth quintile blood levels of carotenoids, such as alpha-carotene, beta-carotene and lutein and zeaxanthin, had significantly reduced risk of developing breast cancer (3).

Thus, there was an inverse relationship between carotenoid levels and breast cancer risk. Even modest amounts of carotenoids can have a resounding effect in potentially preventing breast cancer.

Amyotrophic lateral sclerosis: Lou Gehrig’s disease

ALS is a disabling and feared disease. Unfortunately, there are no effective treatments for reversing this disease. Therefore, we need to work double time in trying to prevent its occurrence.

In a meta-analysis of five prestigious observational studies, including The Nurses’ Health Study and the Health Professionals Follow-Up Study, results showed that people with the greatest amount of carotenoids in their blood from foods like spinach, kale and carrots had a decreased risk of developing ALS and/or delaying the onset of the disease (4). This study involved over 1 million people with more than 1,000 who developed ALS.

Those who were in the highest carotenoid level quintile had a 25 percent reduction in risk, compared to those in the lowest quintile. This difference was even greater for those who had high carotenoid levels and did not smoke, a 35 percent reduction. According to the authors, the beneficial effects may be due to antioxidant activity and more efficient function of the power source of the cell: the mitochondria. This is a good way to prevent a horrible disease while improving your overall health.

Positive effects of healthy eating

Despite the knowledge that healthy eating has long-term positive effects, there are several obstacles to healthy eating. Two critical factors are presentation and perception.

Presentation is glorious for traditional dishes, like turkey, gravy and stuffing with lots of butter and creamy sauces. However, vegetables are usually prepared in either an unappetizing way — steamed to the point of no return, so they cannot compete with the main course — or smothered in cheese, negating their benefits, but clearing our consciences.

Many consider Thanksgiving a time to indulge and not think about the repercussions. Plant-based foods like whole grains, leafy greens and fruits are relegated to side dishes or afterthoughts. Why is it so important to change our mindsets? Believe it or not, there are significant short-term consequences of gorging ourselves.

Not surprisingly, people tend to gain weight from Thanksgiving to New Year. This is when most gain the predominant amount of weight for the entire year. However, people do not lose the weight they gain during this time (5). If you can fend off weight gain during the holidays, just think of the possibilities for the rest of the year.

Heart attack risk: Even in the short term

Also, if you are obese and sedentary, you may already have heart disease. Overeating at a single meal increases your risk of heart attack over the near term, according to the American Heart Association (6). However, with a little Thanksgiving planning, you can reap significant benefits. What strategies should you employ for the best outcomes?

• Make healthy, plant-based dishes part of the main course. I am not suggesting that you forgo signature dishes, but add to tradition by making mouthwatering vegetable-based dishes for the holiday.

• Improve the presentation of vegetable dishes. Most people don’t like grilled chicken without any seasoning. Why should vegetables be different? In my family, we make sauces for vegetables, like a peanut sauce using mostly rice vinegar and infusing a teaspoon of toasted sesame oil. Good resources for appealing dishes can be found at www.PCRM.org, www.DrFuhrman.com, www.EatingWell.com, www.wholefoodsmarket.com and many other resources.

• Replace refined grains. A study in the American Journal of Clinical Nutrition, showed that replacing wheat or refined grains with whole wheat and whole grains significantly reduced central fat, or fat around the belly (7). Not only did participants lose subcutaneous fat found just below the skin but also visceral adipose tissue, the fat that lines organs and causes chronic diseases such as cancer. For even better results, consider substituting finely chopped cauliflower for rice or other starches.

• Create a healthy environment. Instead of putting out creamy dips, processed crackers and candies as snacks prior to the meal, put out whole grain brown rice crackers, baby carrots, cherry tomatoes and healthy dips like hummus and salsa. Help people choose wisely.

• Offer healthy dessert options. Options might include dairy-free pumpkin pudding and fruit salad.

The goal should be to increase your nutrient-dense choices and decrease your empty-calorie foods. You don’t have to be perfect, but improvements during this time period have a tremendous impact — they set the tone for the new year and put you on a path to success. Why not turn this holiday into an opportunity to de-stress, rest and reverse or prevent chronic disease by consuming plenty of carotenoid-containing foods.
