Naturally occurring plant compounds called stanols can help reduce cholesterol. But they may not be found in large enough amounts in butter substitutes to reduce cholesterol levels in the body.

That's because statins, a common type of medication that lowers cholesterol, have both real and perceived side effects, such as muscle aches. To stay on a statin, one can ease into use with a low-dose or an alternate-day dose strategy, consider if other medications or circumstances are to blame for discomfort, try gentle stretching, take coenzyme Q₁₀, or replenish low vitamin D levels. Another strategy is to take a non-statin drug that lowers cholesterol.

Older adults must pay special attention to their intakes of calcium, vitamin D, and protein. These important nutrients are crucial for maintaining bone health. Doctors say it's probably best to take a supplement to get enough vitamin D. Calcium and protein are best when they come from foods, such as canned salmon with bones, sardines, beans, dairy products (cheese, yogurt, cottage cheese, milk), leafy greens, or nuts. Other important nutrients for bone health, such as magnesium, phosphorous, and potassium, can be obtained by simply eating a diet rich in fruits, vegetables, legumes, nuts, seeds, and lean proteins.
