Gargi Sharma says that we should really only be eating cashews a day. Super disappointing. Seven whole shelled nuts is the recommended amount of walnuts per day. Always be careful about how the pistachios are served, or any nut for that matter. Pecans help fight heart disease and cancer as well as boost your immune system. Following the one ounce of nuts per day rule, you should be eating about 15 pecan halves. Pecans are great for vegetarians because they make an excellent substitute for meat.
Packed full of protein and cholesterol-free , these nuts are a good idea for non-vegetarians too. Brazil nuts are very high in selenium, and too much selenium can cause brittle hair and nails. What most of us refer to as 'nuts' actually aren't nuts at all. It's no secret that the peanut has been nothing more than an imposter, a legume seizing our throats and making us itchy since who knows when.
But almonds, cashews, coconuts, pecans, pistachios, macadamias and walnuts aren't nuts either — they're drupe seeds. Who knew?! Whatever they are, research clearly shows they're really good for us, with health experts saying we could probably be eating more nuts for our health.
In fact, one study found people who ate a handful of nuts a day were likely to live longer than those who didn't eat nuts. From raw versus roasted to whether you need to know or care about activated almonds, here's everything you need to know about eating nuts. It's users choice when it comes to which nuts to buy and eat, but if health and nutritional benefits are on your mind, you'll want to mix it up, University of Otago's Department of Human Nutrition Associate Professor Rachel Brown says.
Nuts offer beneficial vitamins and minerals in varying quantities, and eating a variety ensures we're reaping the benefits of each.
Choosing raw and unsalted varieties is preferable says public health nutritionist, Rosemary Stanton. Raw nuts will have a shorter shelf life than roasted ones says dietitian Belinda Neville, but if you're an avid crunch seeker, it might be worth buying raw nut varieties and roasting them at home.
Studies conducted by Dr Brown found there was no difference in the cholesterol lowering properties of roasted nuts compared to raw nuts, when roasted for 10 minutes at degrees Celsius.
Generally, nuts will keep at room temperature for a few months when stored in an airtight container in a cool dark spot. However, not all nuts are created equally. Ones that are high in polyunsaturated fats like walnuts, pine nuts and Brazil nuts are best consumed quickly or stored in the fridge or freezer to ensure they remain fresher for longer, says Dr Brown.
Polyunsaturated fats are susceptible to oxidation — in short, they become rancid which is what can give nuts that "off" taste and weird smell. Studies have shown that those of us who eat nuts regularly, tend to gain less weight over time than those who don't. Copper is an important mineral involved in many aspects of your health, including nerve cell function, immune health, and the production of red blood cells 2. Meanwhile, thiamine , or vitamin B1, is essential for converting carbohydrates into energy to help fuel your body 3.
Pecans are a great source of monounsaturated fatty acids, a type of fat that may benefit heart health 5. One study in people with coronary artery disease, which is characterized by the narrowing of arteries, found that eating 1 ounce 30 grams of pecans daily for 12 weeks improved the ratio of total cholesterol to HDL good cholesterol in the blood 6.
Similarly, an older study in 19 people with normal cholesterol levels found that those eating 2. Other research shows that an increased intake of tree nuts, including pecans, may be linked to reduced levels of total cholesterol, LDL bad cholesterol, and triglycerides — all of which are risk factors for heart disease 8. Some research suggests that pecans may promote better blood sugar control, which may be partially due to their fiber content.
Soluble fiber dissolves in water, forming a gel-like material that moves through your body undigested and slows the absorption of sugar into the blood Insulin is the hormone that transports sugar from your bloodstream into your cells Similarly, a review of 12 studies showed that adding tree nuts to your diet could help lower levels of hemoglobin A1C, a measure of long-term blood sugar control Pecans are brimming with nutrients that may benefit brain function, including mono- and polyunsaturated fatty acids.
Monounsaturated fatty acids, in particular, have been linked to decreased mental decline and reduced inflammation 13 , In fact, a large study in over 15, women lasting over 40 years linked a higher consumption of nuts with improved long-term cognition That said, more research is needed to evaluate how pecans specifically may affect brain function. Some research suggests that pecans may help improve heart health, brain function, and blood sugar control. Although pecans have been linked to several potential health benefits, there are some downsides to consider.
First, those with an allergy to tree nuts should avoid them, along with other types of tree nuts like almonds, cashews, chestnuts, and walnuts. Those with a tree nut allergy should not consume pecans or other tree nuts. Pecans are also high in calories and could contribute to weight gain if consumed in high amounts.
Pecans are loaded with essential nutrients and can be an excellent addition to a well-rounded, healthy diet. Be sure to pay attention to your portion sizes and stick to around 1 ounce 28 grams , or about 20 pecan halves, at a time.
