New Year’s resolutions are all well and good, but we know that maintaining them is another matter altogether. Improving eating habits may be the most popular resolution, so here is a list of some of the best foods to start with from Rodale’s Organic Life.

Grapefruit
Good for your nose and your ticker, this fruit usually gets passed up in favor of its more popular relatives (oranges, tangerines, and clementines) or consumed via sugary โ€œjuice cocktailsโ€ that contain more sugar and food dye than actual grapefruit juice. But its hefty vitamin C content can reduce cold symptoms by 23 percent, studies have found, and a single grapefruit was found in one Israeli study to lower cholesterol. Opt for ruby red varieties, which are sweeter than white and more palatable and reach their height of flavor in early winter.

Beets
These hearty root vegetables store well and will likely pop up at your farmersโ€™ market until summer. Eat them and save your brain. Beets are high in nitrates, naturally occurring minerals that help transport oxygen to your brain. A study from Wake Forest University recently found that older adults with high dietary levels of nitrates (the naturally occurring nitrates found in whole foods, rather than the synthetic versions used in processed meats) showed greater activity in their frontal lobes, suggesting they were better able to ward off dementia, compared to when they were on low-nitrate diets.

Brussels Sprouts
Theyโ€™re full of belly-filling fiber, which will help you stick to those New Yearโ€™s resolutions, and you may still be able to find them at your local farmersโ€™ market. Another benefit to Brussels sprouts: They contain high levels of folate, B vitamin best known for warding off birth defects of the brain and spine when consumed by pregnant women. And surveys suggest thereโ€™s a whole lotta baby-making going on in January, which falls nine months before September 16, the most common birthday in the United States, according to Harvard research.

Turkey
Eating a healthier diet means moving beyond the produce aisles. Thereโ€™s a reason you should include more turkey and poultry in your diet during the winter: The tryptophan in turkey can help ward off the winter blues or its more severe form, seasonal affective disorder, because it gets converted to mood-boosting serotonin in your body. This same amino acid exists in seafood, grass-fed beef, and healthy fats, such as coconut oil and butter from grass-fed cows.

Cauliflower
Cauliflower reaches its peak from December through March. Itโ€™s one of the few vegetables youโ€™ll find at year-round farmersโ€™ markets in January, depending on the climate of your hometown. Like turkey, this cruciferous vegetable has tryptophan, and some of the highest levels of any vegetable. Use it in place of white potatoes to make a waistline-friendly, low-carb version of mashed potatoes.

Pumpkin Seeds
Pumpkin seeds are rich in magnesium, which helps your body convert tryptophan into serotonin, and theyโ€™re basically free, every time you cook a pumpkin, which you may still be able to find locally this time of year.

Avocados
In addition to being rich in tryptophan and magnesium, avocados contain healthy monounsaturated fats, which provide a more sustained form of energy than the quick-burning carbs people tend to crave in winter. Having sustained energy levels will keep your mood elevated, too.

Eggs (vitamin D)
Eggs, particularly those from pasture-raised hens, are rich in vitamin D, a disease-fighting nutrient that comes primarily from sunlight. Since itโ€™s not always practical to head outside, half-naked, to soak up some D in the winter, load up on eggs, which are also filled with mood-promoting omega-3 fatty acids, zinc, B vitamins, and iodide.

Yogurt
Yogurt contains a bacterium called Lactobacillus reuteri that has been found to block the replication of viruses that invade your body when you get sick. Not all brands contain that particular strain of beneficial bacteria, so look for a brand that does. We recommend going organic with yogurt from Stonyfield Farm, which does contain L. reuteri.
