No-Bake Apple Walnut Tart
Prep and Cook Time: 30 minutes, chilling time: about 1 hour
2-1/2 cups walnuts
1-1/2 cups dates (Medjool dates work well)
sea salt to taste
3 green apples, such as Granny Smith, sliced
juice of 1 lemon in 2 cups water
1/4 tsp cinnamon
1/2 tsp allspice
1/8 tsp ground clove
2 TBS honey
1/2 cup apple juice
1/4 cup raisins
Combine walnuts and dates in food processor. Make sure you remove pits if dates have them and cut off end where stem was. Process until well mixed and ground, but not smooth (about 40 seconds). It should be a coarse texture when done. Press evenly into a 9-inch tart pan. Set in refrigerator while making the filling.
Slice apples by cutting into quarters. Cut out core and slice crosswise in 1/4 inch thick slices. Put into lemon water while you finish cutting apples. Drain well in colander when done.
Place apples in a large skillet with rest of the ingredients and cook for about 10 minutes, stirring frequently on medium heat.
Remove apples with a slotted spoon from hot pan to a bowl and cool completely.
Reduce liquid to about half the volume and then cool.
Spread apples evenly over crust. Brush apple-juice syrup over apples. The tart can be served right away or it will keep in refrigerator until needed. Keep tart covered in refrigerator so it doesn’t pick up moisture. Top with a little vanilla yogurt if desired.
The Latest News About Apples
Apples are such commonly consumed fruits that it’s easy to overlook their amazing and unique health benefits. Apples combine certain nutrients in a way that sets them apart from all other fruits and makes them a food of choice for achieving several health goals.
What’s New and Beneficial About Apples
The phytonutrients in apples can help you regulate your blood sugar. Recent research has shown that apple polyphenols can help prevent spikes in blood sugar through a variety of mechanisms. Flavonoids like quercetin found in apples can inhibit enzymes like alpha-amylase and alpha-glucosidase. Since these enzymes are involved in the breakdown of complex carbohydrates into simple sugars, your blood sugar has fewer simple sugars to deal with when these enzymes are inhibited. In addition, the polyphenols in apple have been shown to lessen absorption of glucose from the digestive tract; to stimulate the beta cells of the pancreas to secrete insulin; and to increase uptake of glucose from the blood via stimulation of insulin receptors. All of these mechanisms triggered by apple polyphenols can make it easier for you to regulate your blood sugar.
Even though apple is not an excellent source of dietary fiber (it ranks as a “good” source in our WHFoods Rating System), the fiber found in apple may combine with other apple nutrients to provide you with the kind of health benefits you would ordinarily only associate with much higher amounts of dietary fiber. These health benefits are particularly important in prevention of heart disease through healthy regulation of blood fat levels. Recent research has shown that intake of apples in their whole food form can significantly lower many of our blood fats. The fat-lowering effects of apple have traditionally been associated with its soluble fiber content, and in particular, with its fat-soluble fiber called pectin. What we now know, however, is that whole apples only contain approximately 2-3 grams of fiber per 3.5 ounces, and that pectin accounts for less than 50% of this total fiber. Nevertheless, this relatively modest amount of pectin found in whole apples has now been shown to interact with other apple phytonutrients to give us the kind of blood fat lowering effects that would typically be associated with much higher amounts of soluble fiber intake. In recent comparisons with laboratory animals, the blood fat lowering effects of whole apple were shown to be greatly reduced when whole apples were eliminated from the diet and replaced by pectin alone. In summary, it’s not fiber alone that explains the cardiovascular benefits of apple, but the interaction of fiber with other phytonutrients in this wonderful fruit. If you want the full cardiovascular benefits of apples, it’s the whole food form that you’ll want to choose. Only this form can provide you with those unique fiber-plus-phytonutrient combinations.
The whole food form of apples is also important if you want full satisfaction from eating them. Researchers have recently compared intake of whole apples to intake of applesauce and apple juice, only to discover that people report less hunger (and better satiety, or food satisfaction) after eating whole apples than after eating applesauce or drinking apple juice. But especially interesting was an additional finding about calorie intake following apple consumption. When healthy adults consumed one medium-sized apple approximately 15 minutes before a meal, their caloric intake at that meal decreased by an average of 15%. Since meals in this study averaged 1,240 calories, a reduction of 15% meant a reduction of 186 calories, or about 60 more calories than contained in a medium apple. For these researchers, “getting ahead” in calories with a net reduction of 60 calories was a welcomed outcome of the study, and an extra benefit to their study’s primary conclusion-the importance of whole apples (versus other more processed apple forms) in helping us manage our hunger and feeling more satisfied with our food.
Scientists have recently shown that important health benefits of apples may stem from their impact on bacteria in the digestive tract. In studies on laboratory animals, intake of apples is now known to significantly alter amounts of two bacteria (Clostridiales and Bacteriodes) in the large intestine. As a result of these bacterial changes, metabolism in the large intestine is also changed, and many of these changes appear to provide health benefits. For example, due to bacterial changes in the large intestine, there appears to be more fuel available to the large intestine cells (in the form of butyric acid) after apple is consumed. We expect to see future studies confirming these results in humans, and we are excited to think about potential health benefits of apple that will be related to its impact on bacterial balance in our digestive tract.
Apples belong to the Rose family of plants and are joined in that family by a wide range of very popular foods, including apricots, plums, cherries, peaches, pears, raspberries, and almonds. Foods in the Rose family are simply too diverse in their nutrient value to allow for any one single recommendation about the number of servings that we should consume from this family on a weekly basis. However, when focusing specifically on apples, several anti-cancer studies show daily intake of this fruit to provide better anti-cancer benefits than lesser amounts. So there may be some truth to that old phrase, “An apple a day keeps the doctor away!” Still, we don’t recommend that everyone eat one apple on a daily basis, given the wide variety of available fruits and the nutritional uniqueness of each type. But we do recommend that everyone eat at least 2-3 whole fresh fruits per day, or the equivalent of 2-3 cups’ worth of fresh fruit. Within this framework, if apples are a type of fruit that you strongly prefer, there would be nothing wrong with consuming one on a daily basis, and you may get some special health benefits by doing so.
Apples provide numerous health benefits including:
- Antioxidant properties
- Cardiovascular support
- Blood sugar regulation
- Lung health support
- Anti-asthma benefits
Apple polyphenols are standout nutrients in this widely loved fruit. These polyphenols include flavonols (especially quercetin, but also kaempferol and myricetin), catechins (especially epicatechin), anthocyanins (if the apples are red-skinned), chlorogenic acid, phloridizin, and several dozen more health-supportive polyphenol nutrients. Apple is a good source of fiber, including the soluble fiber pectin, and it’s also a good source of vitamin C. Apple nutrients are disproportionately present in the skin, which is a particularly valuable part of the fruit with respect to its nutrient content.
